Many gamers may have an interest in playing slot machines but don’t know quite where to get started. If you have questions about how slots work, payouts, jackpots, how a player wins, and other topics, this article may help you become more familiar with these popular games. Slot machines can mean a fun night at a casino or simply passing some time on a mobile phone or tablet device with some free social gaming. The chance to win some money can only add to the experience. Free-to-play online games can also be quite entertaining and have become extremely popular as well. How Slot Machines Work A slot machine is a game making use of vertically spinning “reels” that may line up in a certain pattern to potentially determine a random prize for the person dropping money into the machine. That money is collected into a pool and slot machines pay out a certain percentage. Prize amounts vary depending on each machine. The first slot machine was invented by Charles Fey of San Francisco, California, in 1899. That first machine featured three spinning reels containing a total of five symbols: horseshoes, diamonds, spades, hearts, and a Liberty Bell. The machine became known as the Liberty Bell and Fey spawned a growing industry. Those first machines were placed in bars and restaurants throughout San Francisco and paid out not in cash, but with prizes like chewing gum and cigars. Competitors followed with different symbols and many of the symbols one might see on a modern slot trace their roots to these early games. Those first machines are paid out based on the mechanical functions of the machine. There were real reels and how they spun determined payouts. However, modern machines not only often use video reels but also make use of random number generators instead of mechanical workings to determine winners. Modern slot machines have become high-tech machines with advanced video, sound, graphics, and gameplay. A player has numerous games to choose from, something for every taste and interest. In recent years, slot developers have embraced licensing popular movies, celebrities, TV shows, sports teams and leagues, and more. Online slots and social slot-style games have also become extremely popular, with big payouts also coming to players using computers, mobile devices, and tablets. Slots remain the most popular form of casino gaming and are a multi-billion dollar industry. Bottom Line: Slot games date back to the late 19th Century and have become a multi-billion dollar industry. Most modern slots are now high-tech machines with high-tech graphics, sound, video, and more. Here are a few of Jackpot Party's most famous Vegas slots: Click here to explore all of our free slots. RNGs (Random Number Generators) A random number generator, or RNG, is a computer technology that is used to determine payouts and jackpots. Money paid out to players isn’t based on the reels themselves. An RNG creates a sequence of simulated random numbers to determine where those reels will land, and thus which payouts are distributed to players. The RNG creates these sequences at a rate of hundreds and thousands per second. Early mechanical slot machines used actual mechanical workings within each machine to determine winners. Now, a payout and jackpot is determined as soon as the player hits the button to spin the reels. Some slots even still have an arm (as in one-armed bandits) that a player can pull as if playing an old-fashioned casino where a player pulled an arm to spin the reels. This arm only starts the casino reels via the computer innards and the RNG still determines a winning or losing spin. The RNG creates a fair system for players, making slots payout completely at random as the name implies. There isn't as much room for mechanical error and RNGs help make sure the system is also fair to players. One important thing to remember is that payouts and jackpots are completely random. Some players believe a machine that may seem “due” to pay out. This is flawed thinking and payouts all depend on the RNGs. The idea of “hot” and “cold” slots are also misnomers. A player familiar with the concept of RNGs will know that all payouts depend solely on random number generators and while a slot may be “cold,” that can change at any time and the same goes for machines that may seem “hot.” Bottom Line: Slots no longer use mechanical reels to determine winners. The computer inside a game uses a random number generator to determine the result of every single spin. This allows for complete randomness and also allows for differing ways for players to win on the numerous paylines seen on today’s slots, both at a casino and online. Whether you think a slot is “hot” or “cold” doesn;t matter, a slot pays off only according to what is generated by the random number generator (RNG) in the slot’s computer. Paylines, Credits, and Pay Tables Those new to slots may not quite have a grasp on how much money (also known as coin-in) is required and how the differing payouts work. Here’s a look at a few terms that are a key part of this aspect of playing a slot machine: Paylines These are the various lines that will payout on the slot reels. Early slot machines only paid out when certain symbols lined up perfectly across a single line on the front of the machine. Video slot machines however can have numerous paylines with more visible symbols than in early machines. These can go horizontal or diagonal on the front of the reels with some machines even paying out vertical lines. Some payout lines can even run seemingly randomly, depending on the visible symbols. In most modern machines, the number of lines that will pay off for a player depends on the number of credits (money or coin-in) wagered on a particular spin. The more wagered, the more paylines that can pay off for a player. Credits This is simply the name for the denomination a player is paying. Someone playing on a 5-cent machine playing 20 credits has $1 on the line on that spin. A play on a penny machine playing 60 credits has 60 cents on the lines on that spin of the reels. Players who win on a certain spin will find any winnings added to the “Credit” sign on the machine. Those using a slot machine can easily check their balance by looking in this area and determining if they need to add more. Players can also withdraw their funds by hitting “Cash Out.” A user will then receive a paper voucher with the balance amount that can be used in another machine. Vouchers can also be converted back into cash at the casino cashier or a kiosk in the casino. Online slot players can also view their balance at any time and send winning back to their bank accounts as well. Pay Tables Each slot machine has a pay table that shows what symbols need to align for a payout of varying sums. These are arranged with the largest payouts, known as the jackpot, at the top of the tables and subsequent payouts below those. The higher on the table your reels line up, the larger the payout. A table also includes an amount paid out depending on the number of credits a player puts in the machine. Payouts differ depending on the number of credits you play and coin-in can range from one to five credits. Slot manufacturers usually pay out more for players who play “max credits,” meaning the highest number of credits per spin. The highest jackpot, for example, will often be significantly higher for a player at the max-bet amount – someone playing all five credits in the case above. Many slot experts recommend playing at max credits or at least as high as possible so players can receive bigger payouts when they do land on some nice spins. Visit the full article to learn more about slot terms Bottom Line: Knowing the basics of how coin-in and payouts work is essential. Credits are the denomination of “coins” (could also be dollars) a player wagers. Players determine the number of coins they’d like to wager per spin. Paylines are the lines on the reels where a player can win and the pay tables are the charts on a machine that show how much a player wins for certain symbols showing up, depending on the number of credits wagered on a spin. Setting Your Bet Options When making a slot machine wager, players have a few options to choose from. Some slots allow players to select the denomination they’d like to play throughout the session. For example, a player may select a denomination of a penny or a nickel. This means each credit a player plays will be worth a penny or a nickel, depending on which one is selected. Players can also select the bet amount they’d prefer for each spin of the reels. For example, if a machine has a max of five credits allowed per spin, the player can select the bat amount preferred. That could range from a minimum, of one credit, to a maximum of five credits. It’s easy to alter the number of credits you’d like to play as well. Simply toggle through the betting amounts to determine which one you’d like to wager. It’s important to remember that the amount wagered corresponds to payouts on the pay table. Payouts will be larger for a player wagering four credits versus someone betting only two credits. Also, a max bet will pay out substantially larger jackpots than even a four-credit bet. Bottom Line: Players have complete control on the number of credits to wager on each spin. Players can generally determine if they’d like to wager from 1 to 5 credits per spin. You can alter this as needed at any time. Slot Features – Bonus Rounds, Free Spins, & More Bonus Rounds Early slot machines mostly consisted of three reels and a few symbols. Line up some symbols and you can win a few bucks. Modern slots, however, make use of computers, video, and high-tech sound to offer players more of a sensory experience. Manufacturers go out of their way to make games special to keep players not just gambling, but also entertained. Bonus games offer a great way to accomplish this. These are “extra” opportunities for players to win some extra credits without having any real risk. A bonus game is triggered when certain symbols line up, connect, or via some other method included in the machine’s programming. When these are triggered, look for distinct sounds, videos, and other “bells and whistles.” These events allow players an opportunity to compete in some extra games, which could range from touching the screen to making a selection themselves or some other mini-games. Bonus games are extremely popular and add something different to a slot machine experience. Game developers work hard to create a unique experience. These games also regularly include opportunities to win jackpots and grab some multipliers, which “multiply” the amount won by a certain factor. Free Spins Another popular bonus is the addition of “free spins.” These go beyond the credits that a player already wagered on the current spins. The game may include an icon or symbol for “free spins” or may trigger this extra by some other means. These free spins can come via more subdued means, with the player simply making a few extra spins and hopefully winning some nice extra credits. However, many modern slots make free spin opportunities much more of a production as seen in bonus rounds. Players may see extra visuals, sound effects, and even more rapidly spinning wheels. For example, let’s say a player is awarded an extra 10 spins. This player can rack up some extra credits as those reels spin and stop during that time. The winnings are tabulated throughout the free spins and then added to your balance once the session comes to an end. The good news is you can even win jackpots during these spins. It’s also possible to rack up added free spins that only keep the session going longer. These same extras can also be found in online slots and social gaming slots. Slot developers are creative and may have even more ways to win in side games and extra options. These not only allow for winning some extra cash, but they’re fun too. Bottom Line: Bonus games and free spins are extra features that allow players to win some extra credits. Bonus games usually involve a completely different game with added graphics and sounds. These can reward jackpots as well. Free spins allow players to earn more credits and even additional spins, with multiple free spins usually running quickly one after another and add to the fun of playing a slot. Slot Odds As noted here, slot machines and online slots are house-edge games, meaning a player is up against the house, unlike games like poker. You also can’t shift those odds in your favor via card counting or superior play as in blackjack or video poker. But what are the odds of winning in a slot machine game? That all depends on the property and the actual machine. Some experts estimate that odds of winning a jackpot can range from 1 in 5,000 to 1 in 34 million, depending on what a person is playing. Progressive jackpots feature extremely long odds, but also massive payouts for winners. Check out the article on how to play progressive slots. Because of the long odds, expecting to win a huge jackpot is probably unrealistic. Hitting millions of dollars is similar to winning the lottery. Players looking to win need to look at the payout percentages of each property, meaning the percentage of coin-in that is paid back out to players. A property boasting a payout percentage of 94% means that the casino is only collecting about 6% of all money going into the machine for the house. Payout percentages can be programmed into a machine and those in the upper 90s can be very favorable to players and offer better odds at winning. Online slot players may find even better payout percentages than what might be found at live casinos. Players should also lower expectations of big wins because of the long odds involved. Slots should be seen as any other form of entertainment, but with a shot of winning some money. Slot gambling can produce huge results occasionally, but even a win of a few hundred dollars is a nice night. Those who enjoy playing social gaming slots may find their odds much better than when playing real money slots online or in a casino. Social games tend to reward players more, with winning sessions and nice scores much more common as players accumulate points and other rewards to advance up certain steps or levels. Bottom Line: Players face long odds when it comes to winning a major jackpot, especially on a progressive machine. However, winning smaller amounts is certainly possible. Determining casinos with higher payback percentages offer players more chances to walk away as winners. Payouts A payout is a term for money paid out to players who score a winning spin. Modern slots offer many more payouts that might be seen in earlier slot games. Developers know that players want to win and work to at least allow players to win some of their money back. A spin may pay back only a portion of the amount wagered on that particular spin, double the total, or even more. This gives players at least some sense of winning and keeps them playing. This also allows for longer sessions so that a player’s bankroll will last longer. Those who take their time and aren't afraid to walk away for a bit can make that money last even longer. (See Slot Tips Below) A player who can find more winning spins than losing spins can hopefully accumulate a winning session. Those who keep finding winning payouts don’t have to put more funds in a machine, and those who continue playing have a chance at some of the larger payouts, also known as jackpots. See more on that below. Payouts are determined by symbols. Hit a spin with more of the common symbols or graphics and a player can expect a smaller win. Those rarer occurrences will bring larger payouts. Winning credits is the same as a payout, and the goal when playing a slot game. Bottom Line: A payout is a total won for a particular spin. A player doesn’t have to win huge amounts to see a payout. Players who score a nice win can hit the “Cash Out” button at any time to take some of those winnings and visit the cashier. Players at online slots will find the same scenario and can cash out some of those winnings at any time as well. How Jackpots Work A jackpot is a big payout determined by certain symbols aligning just right in a slot game. These payouts may vary in size and are a bit rarer than typical payouts on a machine and are generally much larger. A jackpot is built by a certain machine putting “aside” a certain amount of coin as players battle it out at the slots. That prize pool continues to build in the event those certain numbers are generated by the RNG and one lucky player scores some big money. Hitting a huge jackpot isn't easy or everyone would be winning big. Many machines pay jackpots on several levels. A player may not always hit the biggest payout, but at least has a shot at a few smaller jackpots that still may be larger than typical payouts on an average spin. For example, a game may offer players jackpots using terms like these: Mini –  a smaller jackpot, but can still be a nice payout. Major – an even bigger prize that rewards winners nicely. Grand – the largest jackpot available on the machine that stands out and may trigger a bell for a payout from casino staff. Online slots follow a similar system and allow players to win some major jackpots as well. As noted in the next section, progressive slot machines offer players a chance to win even bigger jackpots with life-changing money heading to lucky winners. Bottom Line: Jackpots are larger prizes that pay out much more than average payout on a typical spin. Those lucky enough to win a jackpot may score thousands and thousands of dollars. Slot manufacturers also include smaller jackpots that can still pay out significant amounts to players. Progressive Jackpots Certain machines offer players a chance at some really staggering payoffs. That could be in the millions of dollars and numerous lucky slot players have taken home seven-figure sums. These games are known as “progressive” slots. How do these payouts get so huge? Progressive machines are linked in a certain geographic region. For example, a player on a progressive in Las Vegas can play a machine that is linked to all of those same machines within Nevada. As more and more players add coin-in (the term for the amount of money put into a machine), a certain percentage is set aside for jackpots. The more these machines are played, the larger the jackpot gets. There is usually a mega jackpot and also some smaller jackpots as well. These pay off when a player hits the jackpot just right. This is rare but can have huge payouts when someone does hit it just right. The largest progressive jackpot came in 2002 at the Excalibur in Las Vegas on a Megabucks machine. This lucky gambler took home a score of $39.7 million after spending just $100. That was quite a score and certainly made for a nice Vegas vacation. Check out the article on the biggest jackpot wins in history. Bottom Line: Progressive jackpots can pay much more than a typical jackpot because these games are linked with other games throughout a certain region. Each machine “sets aside” a certain amount for the prize pool, which can really accumulate considering there are so many other machines connected to the system. A player hitting it big on these games for a progressive jackpot has a chance to win millions and millions of dollars. Slot Tips, Do's and Don'ts The first thing a player might want to realize when playing a slot is that casinos always have an edge. Unlike games like blackjack, poker, and video poker, a player can't flip the odds in his favor based on superior play or strategy. However, there are a few important concepts to remember when playing slots to offer not only the best chance to win but also a chance to at least make a player’s bankroll last longer. Here are just a few tips to remember. Set Your Limits – make sure the money plan to wager is a major part of your budget. Slots and gambling are forms of entertainment. Make sure losing your slot bankroll isn't more than you can realistically afford to lose. Try not to avoid heading to the ATM machine – your budget is important. Check Out Payout Percentages – A payout percentage is an amount a casino’s slots pay back to players. The higher the percentage, the better chance a player has to have a winning session. The same can be said for slot manufacturers, some pay back more to players than others. A simple Internet search should help you determine this and it’s a good idea to play more of these properties and games. Slow Down – Playing faster only keeps more of your hard-earned dollars flowing into the slots. A more leisurely pace helps a player make his money last longer. It’s also great to take a break or find another game if you hit a losing streak. Get Rewarded – It’s always key to join a casino’s players club. The property’s rewards card offers you a shot at extras as you play, such as free meals, hotel stays, entertainment options, and other perks. Many casinos also offer “free play” options, meaning a player earns a certain amount of slot play for nothing. A player hitting a nice win on these spins can keep the winnings. Move Down If Needed – Those who find their dollars flying away at higher denominations shouldn’t be afraid of moving down in denominations. A person playing at quarter credits may want to try nickel slots if the bankroll is looking particularly strained at that level. Those who can afford higher denominations may also want to consider this as well. Higher credit levels tend to have higher payouts, but again only do this if you can truly afford it.

Join the player’s club for a shot at some free rewards as well as hopefully some free slot play. These are just a few of the good ideas to remember when planning that next slot getaway – or even just playing online at home. Slot machines can be a fun way to pass some time at home or to plan a full casino vacation. Practicing and learning how to play slots, as outlined here, can make for a much more rewarding experience.

Playing a slot machine can bring hours of entertainment and excitement, but like many games, these popular devices have their distinct terminology. Beginners may be a bit overwhelmed when playing at a live casino or on an online gaming platform. From jackpots and payout percentages to bonus games and progressive games, numerous terms exist to learn and consider when jumping into the action. While not a complete grasp of all the ins and outs of a slot isn't required, having a basic knowledge can be understandable. With that in mind, here's a look at some of the terminology that goes along with playing a slot at your local casino or simply on your mobile phone. This article offers readers everything they might need to know about slot terminology and some of the key concepts synonymous with slot machines. Slot Payout and Money-Related Terminology These terms involve a player's money and credits on a machine. You'll find these terms helpful in adding credits to a machine, determining how much to play for, and what to expect when cashing out. Balance – This is the amount of money you have in the machine. Once you deposit your money, you should see this on-screen in the form of credits for that machine. For example, if you slide $100 into a 25-cent machine, the balance should be 400 credits. This amount goes up and down depending on winning and losing spins. Cash-out – This simply means taking your funds out of the machine. There is usually a "cash out" icon on the screen or a real button on the machine itself. Once a player has cashed out, he or she will receive a voucher. This can be used in other slots instead of cash or can be taken to the cashier to exchange for cash as well. Online slot players can also cash out their winnings and go to a different game. Coin-in – This is an industry term for the amount of money input into a machine. Slot machines pay a certain percentage of coin-in back to players. Credits (also known as units) – This is the amount of a coin-in you have inserted into a machine. A single credit is the lowest denomination allowed on a machine. For example, a player on a penny machine may put in $20. That would mean the player would have a balance of 2,000 credits to begin the session. Minimum bet – As the name implies, this is the minimum credit that can be bet on a certain slot game online or in a live casino. Payline –  These are the lines on a machine or online slot where the game's symbols must line up to determine a winner. The paylines can be horizontal but also vertical, diagonal, and run in other directions, especially on video slots. On more traditional-type slots, these can be found right on the exterior of the machine in front of the reels. However, on video slots, the paylines can be determined in many ways and the machine will visually display the multiple ways a player has won using paylines. Also, players have the option to play numerous paylines on modern video slots as well. This system can also be found on online free slots. Active payline – These are all the paylines in play during a certain spin of the reels. A player with the max paylines will have all paylines active on each spin. Payout Percentages (also known as RTP, meaning a return to player) – This is the amount of coin-in paid back to players at a particular casino. These numbers are usually available online, and finding properties with better payout percentages may offer a better chance for players to win. Players may want to look for rates above 90 percent. Occasionally, some of these get higher than 95 percent. Pay Tables – This is a chart (or table) found on the machine itself or the screen of a video slot. This details the combinations that will win and how much they return depending on the slot machine symbols that appear on the machine. The table features several rows to show higher levels of combinations and also columns that show various payouts depending on the number of credits paid per spin. Progressive Slots – Progressive jackpots are slot games that are linked to a certain region or jurisdiction. A certain amount of each player's spin is siphoned into a much larger prize pool. With so many players linked together, those player pools can grow extremely large. Online slot players can also benefit from playing these types of games as well. Some of these mega jackpots regularly pay out seven figures; historically, some have even reached eight figures. Click here to learn how to play progressive slots. Ticket or voucher – The paper coupon printed by a slot machine when a player cashes out. This functions as cash at a slot machine and can be input at another slot to continue playing. You can also exchange these for real cash at the casino cashier or kiosks throughout the property. Take your pick and enjoy our incredible slots below: Click here to dive into our wide array of free slots. Slot Gameplay Terminology Auto-play/Auto-spin – This is a setting on a slot where the reels spin automatically and a player doesn't have to keep hitting the "spin" button. Auto-play spins the reels automatically for a certain amount of time, with atop-spin keeps the reels spinning for a certain number of spins. Basic slot – This is a traditional-style slot with only one payline and fixed payouts. Bonus game – This is an extra game aside from the normal spinning of reels on a game. Players can activate these bonus features depending on a combination of symbols that show up on the machine. These games may have players making certain selections or competing in other forms. Bonus games offer players a chance at more significant wins and can help create a winning session. Second screen bonus – A bonus game that shifts the action to another screen, often found above the main screen. These usually offer players options and other secondary games to determine further winnings and possibly a jackpot. Cascading reels (also known as tumbling reels) – This is another fun twist seen on some modern slots where certain symbols disappear, with others sliding in to take their place. Free play – These are free spins often given to players who join a casino's slot club (also known as a players club or a rewards club). Many casinos offer a certain amount of free play just for signing up for the club. You may also earn free play as you accumulate reward points for playing. Free spins – This is a type of bonus that certain symbol combinations in a game can also trigger. The game often begins spinning the reels automatically and counts down from the free spins. Players can accumulate wins and credits without having to dip into their balance. This offers an opportunity for players to accumulate extra wins toward a nice session. Hit frequency – This is the term used for the number of times a slot may be expected to pay out. Hopper – This type of machine features an option where players can keep certain lines on one spin and then "hop" them into another. This gives players an extra shot at landing highly-sought combinations that might result in larger wins. Jackpot – This is a larger than the typical payout on a slot machine. Players will usually find that games in a live casino and online have several jackpot tiers, from a small jackpot to even much larger payouts. These are often mini, major, minor, and mega jackpots. That range offers players multiple ways to win more than the average amount that can be found on an average spin of the reels. Players on online slots also have a shot at these jackpots. Loose slots – These slots are deemed to have a high payout percentage, meaning that a higher-than-normal amount of coin-in is paid back out to players. These offer players a higher chance at a winning session. Max bet – A player is betting the maximum amount of credits per spin allowed on a machine. There is often a "max bet" button on the machine itself or as an icon on the screen. Max bets pay the most for win on the pay table. Players usually have from one to five credits allowed to be played per spin. Mobile slots – Games that can be played on a mobile phone or tablet device. This is a fast-growing segment of real-money casino gaming, but this can also refer to free-to-play games. In addition, social gaming in the form of fun and free slot games has also seen significant growth in the gaming industry. Multiplier – This symbol or image allows players to see their point total multiplied by a certain amount if activated. Nudge slot – This is a popular feature on many modern slots in which machine may "nudge" the reels up or down into a winning position. What may have looked like a losing spin may turn into a winner once the nudge function repositions the symbols on the reels. Reels –  vertical cylinders spin within a traditional slot machine that display various symbols to help determine a player's win or loss. Originally, these were mechanical devices, and where they stopped was totally determined by the mechanics of the machine. In modern slots, however, the random number generator (RNG) determines a winning spin. Many games that look like traditional machines may still have reels, but the RNG still determines where they stop and with what symbols are displayed. Video slots, including digital online and social gaming slots, also feature "reels". Still, these are simply graphical, but mimic a slot's traditional look and feel but with modern gameplay twists. Three-Reel Slot – As the name implies, these are simply games featuring three vertical reels as found in traditional slots Five-Reel Slot – This is just simply a game with five spinning reels. There were three reels when slots were invented, but games have expanded through the years to offer more reels and ways to win. 3-D slots - 3-D slots are modern video slots often found online that feature three-dimensional images and graphics. RNG – This stands for "random number generator" and is the key to how the results turn out on a modern slot game. No longer do machines make use of mechanical reels to determine if a player wins. Instead sophisticated software and casino algorithms are used as part of the machine's random number generator to determine completely random winners. Slot tournaments – These are multi-player contests in which players spin the reels of a slot machine in competition. Casinos often run these as promotions for loyal players. Slot tournaments are often large payouts and other prizes from the casino for winners. Symbols (also known as icons) – These are the graphical images used on the front of reels as well as on video and online slots that visually display a slot result. If the RNG determines a win then these will align in a certain pattern or combination. Traditional and historic symbols include fruits, bars, 7s, playing cards and suits, and much more. Video slots now use numerous symbols, video, and other graphical elements. Wild multiplier – A wild symbol that can activate a multiplier when triggered, giving a player more winnings than might otherwise have been awarded. Those winnings are multiplied by a certain amount. Other slot terms Here are some other terms players may want to know as they begin playing slot games. Free play – This is free slot play usually given to players as a reward for a certain accomplishment. Many casinos offer free play for those who join the casino's rewards program. Regular players in a players club may also earn free play as they accumulate reward points. Hold percentage – This is a casino's amount of money played into a slot machine. This is the house edge and the money a casino collects from all players' coin-ins. Hot and cold slots – Generic terms for a machine that has been paying out a lot (hot) and one that hasn't been paying out (cold). However, these notions are mostly a myth with modern slot machines, as the RNG determines random winners. Lever – This is a remnant of early slots in which a player pulled a lever on the side of the machine to spin the reels. Modern technology has made this part of a slot machine obsolete. However, some machines still offer a lever as a throwback to those classic machines. You can pull the lever to activate the reels, but the lever doesn't have a mechanical function. The machine's computer activates the reels with the lever functioning like the "spin" button. Licensed slots – This refers to a game using a popular character, TV show, movie, or other brands in pop culture. This has become a trend in modern slot games, with more slot manufacturers offering players a bit of pop culture or nostalgia. Mechanical slots – This refers to older, classic mechanical slot machines that feature real mechanical mechanisms inside the machine. Modern slots no longer need mechanical parts or a lever crank to get the reels spinning. Mobile slots – These are just online slots that can be played on a cell phone or tablet device. Multi-line slots – These are games that feature numerous paylines beyond just the traditional horizontal paylines found on older machines. Players club (also known as a loyalty or rewards club) is the casino's program to reward loyal players. Those who play often at the casino can earn free play., hotel stays, food comps, and other prizes. It pays to join the rewards club. Players will receive a player card to insert every time they play a slot game. This helps track your play so that you accumulate points based on your play. Online casinos may also have rewards programs that offer prizes and bonuses. Volatility – Refers to a game's payout frequency. Those with a "high volatility" pay out high amounts but with fewer payouts overall. "Low volatility" slots pay out more often but in smaller amounts overall. Conclusion These are some basic terms a player may want to be familiar with when heading to play some slots. However, don't get overburdened with jargon. Instead, learn the basics, know what you're getting into, and have fun!

Heading to a casino to play some slot machines can be a great way to relax, celebrate, enjoy some time with friends, and take in some entertainment away from home for a bit of relaxation. Slot games also offer a chance at taking home a few extra bucks in your pocket as well. But how do these games work and what can a new player expect when taking a seat at a machine or perhaps playing a slot online or in a social media environment. These games are more than just a few reels with a spin button. There’s a lot that goes into these casino offerings that have become the most popular gambling options in a casino. They’ve also become extremely popular in real-money online gaming as well as a free-play reel-spinning option as a social game to pass some time on a mobile phone or tablet. Keep reading to learn more on how things games work and how to have some fun – hopefully with some winning results. Inside a Slot Machine Whether at a live casino or online, modern slots are advanced computing devices. No longer do machines make use of a handle to spin real mechanical reels (hence the old name, “one-armed bandits). Today’s slots are computerized devices making use of complex software, high-end graphics and sound systems, and much more. Today’s games might have more in common with your home computer or video game system than early slot games. Wins are no longer dependent on those reels really at all. They may line up and display certain graphics and icons, but how a player fares is determined by a random number generator (RNG) programmed into the computer’s software. This guarantees a completely random outcome and is made possible via slot machine algorithms within the game’s programming that are based on digital simulations. Payouts are simply based on the inner workings of the game running millions of simulations per second to reach a random result. For more information, read the article: Are Slot Machines Trustworthy A slot’s results on every spin of the reels are completely random outcomes and the idea of a “cold” or “hot” machine isn’t a reality. Some may pay out more but this is more of an act of randomness. The idea that a machine is “due” to pay out is also a myth. That doesn’t mean a casino can’t manipulate a slot machine at least when it comes to payouts. A casino can determine how much of the coin-in (credits used to play on a machine) is paid back out to players. This is known as the payout percentage and the higher that is the better it is for players. The more money paid out the more opportunities for a player to win (more on that subject below). How Slot Machines Pay Out Winning is certainly a big part of playing a slot machine – at least that’s the goal. So how does a slot machine payout work? The first thing to know is that each machine has a limit. Some may be penny machines while others start at a nickel, quarter, or dollar. That is just the minimum coin-in to spin the reels. However, players usually will want more than one active “pay line” on each machine. The pay lines determine whether a player is a winner, depending on how the icons on the spinning reels align. Most games today feature video reels and those whirl around and then come to a stop. Different icons or graphics “determine” which prize a player wins (remember, the RNG actually determines each spin). Modern slots allow players to play numerous paylines, which may feature several horizontal lines as well as some running vertically, diagonally, and numerous other directions. These additional pay lines offer players more chances to win on each spin of the reels. This adds to the fun and keeps players winning at least sporadically as they play on one of these casino games. Players who line certain icons up just right can also earn additional chances to win through such popular extras as bonus games and free spins. Bonus Games often involve additional graphics, sounds, and player selections to determine larger prizes. These often payout out some form of jackpot as well, usually noted using words like: Mini Jackpot/Award Minor Jackpot/Award Major Jackpot/Award Hitting some of these can add some extra excitement to a slot session. If you’re lucky enough to find a nice payout, that score can make for a nice winning session. Free Spins are also a great way to accrue extra winnings as you spin away without touching your current credit balance. These can also win players other extras on the game that can add to their winnings, such as additional Bonus Games. Along with these traditional payouts, players can win smaller amounts on each spin. These more marginal wins at least offer you some sort of payout to keep your bankroll lasting longer. That then allows you to play longer and hopefully land a larger win.

Those new to the world of slot machines may notice a table on the game screen, or somewhere on the game itself when taking a seat. The table features several rows of columns, offering information on what to look for when playing. The rows start with smaller payouts at the bottom and work up to the larger payouts toward the top. The jackpot-level payouts are located at the very top of the table, as the odds of hitting a jackpot are the smallest, but they come with the biggest prize. The columns in the pay table represent the payouts based on the number of credits, or coin-in, that a player pays per line. There are usually five columns, but there may be as few as three depending on the machine. Players can play the minimum credits per line, but may also want to pay more per line. The more credits per line you wager, the higher payouts you can win on each spin of the reels. Many experts recommend playing the “max bet” if at all possible. This strategy allows players to win more throughout their sessions at the slots when they do hit some nice spins. Additionally, some games pay out considerably more at higher wins for some of the upper levels on the pay table. It’s important to note that despite all the bells, whistles, and payout structures, the slots software and RNG (random number generator) still randomly determine the actual prize a player will win. The digital aspects of the game may mimic mechanical reels and movements, but the computer inside is the brains behind the operation. When playing a slot it’s important to remember: RNG (random number generator) – determines the result of a spin Pay lines – display visually the result of a “spin” as determined by the RNG Payout percentage – the amount of coin-in that a property pays out to players Pay table – shows how a slot pays out when certain symbols appear in certain combinations Slot Machine Types Those gamers heading to a casino to play some slots will usually find a wide variety of games to check out. There is something to suit every mood or taste. Here’s a look at some of the machine types a player might find in a casino. Traditional-Style Slots When it comes to slot machines, many players may think of classic games featuring 7s, fruits, playing cards and suits, horseshoes, and other icons. These original devices featured real mechanical spinning reels and didn’t offer the numerous payout lines available today. They lacked the modern “bells and whistles” seen on many of today’s video-based slots. While slots may have changed, many players still enjoy these types of games and manufacturers still work to give these traditional games a modern twist. Many games still feature some of these traditional setups but also feature multiple payout lines, Bonus Games, and other modern additions to the games. Modern Slot Machines Those thinking of old-school mechanical reel slots may be surprised when heading to the gaming floor at a modern casino. Today’s games use plenty of technology to entertain slot players. These involve highly innovative design, sound, video, and other digital aspects one might expect at a movie theater rather than a casino. Speaking of movies, many slot manufacturers have also added elements from popular films, TV shows, musicians, and much more. That often includes videos that appear on the screen while playing. There's a good chance some of your favorite rock bands or musicians have their slot machines. From Ozzy Osbourne to KISS and Michale Jackon and Dolly Parton, artists across the musical spectrum have lent their names and songs to casino games. On the TV and movie side, look for every major pop culture title from Ghosterbusters, Goonies, and Jurassic Park to Sex and the City, Baywatch, and Star Trek. Developers are going out of their way to appeal to all types of players with their favorite song, artists, storylines, and characters. Slot manufacturers continue to raise the bar each year with many offering new features and innovations every year. Online and social gaming slot developers also continue to offer creative options for players looking to play at home on their computers, mobile phones, or tablet devices. Slots have certainly come a long way. Progressive Jackpots Modern slot machines also allow players to play for truly remarkable jackpots through the use of progressive slots. These are games that are linked via computer technology to others within a certain state or region. A portion of all coin-in is funneled to progressive jackpot payouts. With so many players a part of the jackpot pool, these can build to millions of dollars. Players have regularly been paid out in seven figures and these massive jackpots regularly produce some major headlines. The largest progressive jackpot payout came in 2003 at the Excalibur Casino in Las Vegas. A lucky player from Los Angeles hit it huge on a Megabucks for $39 million on a $100 wager. Progressive slots offer players a chance to play for real life-changing money. Not every player jumping in a progressive slot is going to hit it big. However, most of these games also have differing levels of jackpots. A player may be rewarded with a smaller jackpot that pays out considerably as well, but maybe in five or six figures instead of seven or eight. Progressives offer you a nice slot experience and plenty of opportunities to dream of really hitting it big. Other Slot Options Beyond these slots, there are a few others players might consider. Video poker often referred to as “poker slots,” is often found in the slot machine area of a casino as well. This is a fixed-odds game based on a five-card draw poker game. Instead of fruits, 7s, and other icons, players use playing cards to work toward a win. Players are dealt five cards and decide which they want to keep and which they want to discard and draw. There are various versions of these games including Jacks of Better, Deuces Wild, and others. Unlike traditional slots, however, there can be some real skill to video poker. Players who can learn and incorporate basic strategy for these games can trim the odds and in some cases (which may require rewards comps earned along the way), flip the odds in their favor. One interesting game that also is similar to slots is the Fortune Cup and Sigma Derby horse racing games. These allow for some group dynamics as players crowd around the game and make their selections. Each selection even comes with differing odds as seen in a real horse race. You can then cheer as your horse races around the track. Konami's live mechanical Fortune Cup adds some nice realism. This can be a fun addition to that next casino slot machine outing. A nice slot jackpot followed by a horse racing quinella could make for a perfect weekend. Check out this article on the types of slot machines. Slot Payout Percentages As noted above, payout percentages are the amount of money that goes into a machine that a casino then pays out to players. Many online resources are available for finding which properties offer the highest payout percentages, especially in casino hotspots like Las Vegas and Atlantic City. This allows a gambler to determine what properties would be better to visit with the best chance at seeing some of those credits a machine pay off in the form of a nice win. Not every session at a slot machine can be a winner, but higher payout percentages offer you a chance to hopefully some of that return back to your credit balance, hopefully with some excellent returns along the way. Percentages can top 90 percent in some properties with some of those numbers even climbing above 95 percent. These are nice figures in a slot player’s favor, considering the house always has an edge when it comes to these casino games. Beyond payout percentages for casinos, some slots also pay out a larger percentage of dollars put in the machines than others. This can often be found online and finding a few of your favorites among the better-paying machines may be a good idea for the next time you head out to a casino. Another idea to keep in mind is that machines with higher limits tend to pay out more than those with smaller buy-ins. If you have a budget you could play nickel- or quarter-slots rather than penny machines. Along with offering higher payout percentages, you’ll also earn more along the way on these higher denomination machines when you do hit a nice winning streak. Slot Credits, Coin-in, and Balances At one time, slot players could be seen carrying around buckets full of coins. These were filled with coins or metal slot tokens that players used to play in their favorite machines. There was an actual “slot” that a player would input the coin or token into, thus the name “slot machine.” The days of needing a bucket full of coins have been gone for many years, save for a few classic slot machine offerings one might see at downtown Las Vegas casinos such as The Plaza and D Las Vegas. Instead, players can now slide cash directly into a machine with the stakes of their choice. You will then find that amount showing up in the “balance” area of the screen and often in another area of the slot near the “spin” button. The display may also show the number of credits you have in the machine based on the money you’re inserted into the game. For example, $100 put into the machine at a $1 machine means you have 100 credits available to bet. If you put $100 into a quarter machine, you’ll have 400 credits to get. Players can usually bet between one and five credits on each spin. Again, consult the pay table on the machine to see what the payouts are for various coin-in levels. Once you’re ready to move on to another machine or take a break for a while, simply press the “cash out” button on the machine or the screen to retrieve your cash. Don’t look for real money to come from the machine, however. Slots now print out vouchers that can be inserted like cash at another machine. This will transfer the remainder of your balance to the next slot you choose to play. If you’d rather have cash, you can take this to the cashier (also known as the cage) to exchange it for real money. Most casinos also have kiosks where you can input the voucher to receive cash as well. Online and social gaming slot players will find a similar setup. However, depositing money usually involves going through a signup process and using a major credit card, ACH bank transfer, e-wallet, or some other safe deposit method. Once that’s complete, you should then be able to begin playing at whatever stakes level you choose. Like brick-and-mortar casinos, online gaming companies also offer a wide variety of games (many times even more than live casinos) and stakes. These online casinos make it easy to move from one slot to another. A player’s balance will automatically move between games and players can also cash out at any point. Many online slot operators will transfer a withdrawal directly to your bank account or via your preferred deposit option. While free-money social gaming slots don’t usually pay out real money, there may be prizes, badges, elevated tiers, extra points, and other elements that players can win along the way on their slot journey that make it a fun experience.. Slot Rewards and Players Clubs When heading to a casino, a wise move is to join the players club first. These clubs are free and you’ll earn rewards points as you play. Simply insert your player’s card every time you sit down and play. Rewards points can earn a player: free play restaurant and hotel comps other prizes Some properties also offer regular special giveaways for club members. Often, simply signing up for a player’s card also earns a player some free play and maybe even a meal or free drink. Online players may also earn rewards as they play as well. Many online casinos also offer bonus offers for players making their first deposit. These can be as much as 100 percent of your deposit and sometimes even more. Players' rewards and bonuses are worth the effort.
