Quick Step-by-Step Slot Play Guide for Vegas Beginners Choose Your Casino: Las Vegas offers a plethora of casinos with different themes and atmospheres. Pick a casino that appeals to you, keeping in mind factors like location, reputation, and any other specific preferences you might have. Set a Budget: Decide how much money you're willing to spend on playing slots and stick to that budget. Slots can be very entertaining, but it's crucial to gamble responsibly. Get Cash: Most slot machines in Las Vegas accept both cash and ticket-in, ticket-out (TITO) vouchers. You can either bring cash or use ATMs available within the casino. Avoid using credit cards at ATMs to prevent overspending. Select Your Slot Machine: Walk around the casino floor and explore the various slot machines available. They come in different themes, denominations, and styles. Look for a machine that appeals to you visually and fits your budget. Insert Money: If you have cash, insert it into the bill acceptor or use the designated slot to add your bills. If you prefer to play with a TITO voucher, locate a redemption machine to exchange your cash for a voucher. Choose Your Bet: After your money is in the machine, you'll need to select your bet amount. You can usually adjust the bet per line and the number of lines you want to play. Keep in mind that betting more per spin can lead to larger potential payouts but also increases your risk. Spin the Reels: Once you've set your bet, press the "Spin" button or pull the lever (if it's a classic slot machine). The reels will start spinning, and the symbols will land randomly. Watch for Winning Combinations: Keep an eye on the paytable, usually displayed on the slot machine or on a nearby screen. This shows the winning combinations and their corresponding payouts. If the symbols align in a winning pattern, you'll receive your winnings. Collect Winnings: If you win, the machine will automatically add your winnings to your credits. You can either continue playing or cash out by pressing the "Cash Out" button. If you're playing with a TITO voucher, you can redeem it at a redemption machine or take it to the cashier. Know When to Quit: It's important to recognize when to stop playing. If you've reached your budget or have been playing for a while without significant wins, it might be time to walk away. Enjoy the Experience: Slot machines are designed to be fun and entertaining. While winning is exciting, remember that slots are primarily a form of entertainment, and the odds are usually in favor of the casino. Join the Player's Club: Many casinos offer player's club memberships that provide perks like discounts, free play, and other rewards. Sign up if you plan to spend time in the casino. Remember, playing slots should be done for entertainment, and it's essential to gamble responsibly. Set limits, stick to your budget, and most importantly, have fun while you're in Las Vegas! How to play slots in Las Vegas While casinos offer plenty of entertainment options, from table games to big-name shows to sports betting, slot machines have become the most popular form of casino wagering in recent years. They are simple to play and modern machines offer plenty of amazing graphics, sound effects, and fun beyond vintage games that may have simply featured three reels spinning with a few symbols on each. Instead, slot fans now can find games with slot themes of every variety. Pop culture has become a popular theme in recent years. Players can expect games featuring: Movies and TV shows Music bands and singers Animals and nature Activities such as sports Asian-themed slots Video poker And much more There is literally something for everyone and at every limit level as well. Most games start at simply one cent per payline, the lines used on the reels to designate winnings spins. Now that you know a little about these machines, how exactly do they work? A slot is basically built around a set of reels that spin vertically. In the old days, these were real mechanical machines with symbols that were used to show a win if they lined up correctly on the payline. Modern slots, however, are based on software and RNGs (random number generators) within the machine. Reels are also mostly represented on a video screen now on most games. Players no longer need to pull a mechanical reel to activate the reels, and can simply press the “spin” button. Click here for further information on slot machine reels. Modern slots also offer more paylines to add more opportunities to win. Players now enjoy bonus games, which may even require user interactivity, and free spins to add even more chances to win. Wild symbols can also substitute for other symbols on the reels to make for extra winning combinations. Players new to a slot may want to check the pay table as well when starting to play. This is usually located on the video screens and shows the best winning symbols and combinations – including what needs to align to win a jackpot. The entire process of playing a slot in Las Vegas or at any other casino is simple and here’s a guide with a few concepts to remember.

How to play progressive slots in Las Vegas Players new to slot machines may have seen occasional stories in the news about eye-popping jackpots occasionally paid out to players. These can top $1 million with the largest jackpot ever paid checking in at much more. In 2003, a player at the Excalibur Casino in Las Vegas hit a $39.7 million jackpot after depositing $100 in a Megabucks machine. This type of machine is called a progressive slot machine. These games take a portion of each spin and place that into a separate prize pool. The games are linked together in a certain jurisdiction or area, and that prize pool continues growing until someone hits it big and scores a massive chunk of the total prize pool. This is what allows a slot to pay out such staggering prizes. Players dropping some cash in these games also have chances at some other smaller, yet still large, jackpots as well. Most casinos in Las Vegas as well as in other casino destinations offer at least progressive slot games. These offer chances at massive paydays but it’s important to remember: Massive jackpots are rare. Most progressive slots require players to play maximum credits to qualify for the largest jackpots. Some progressives require higher stakes than non-progressive slots. Those traveling to play in Vegas will find many opportunities to try out a progressive slot machine. Playing progressive slots offers a chance to dream about what it might be like to really hit one of those huge jackpots. That likely isn’t going to happen, but some nice wins could still come your way as you try to hit it big.

They often feature elaborate storylines and interactive bonus rounds. These machines aim to provide a more cinematic feel to slot gameplay. Fruit Machines: Fruit machines, inspired by British pub-style slots, are less common in Las Vegas but can still be found in some casinos. They typically have basic gameplay with fruit symbols, nudges, and bonus boards. Multi-Line Slots: Multi-line slots allow players to activate multiple paylines on a single spin, increasing their chances of winning. Players can choose how many lines to play and how much to bet per line. Some machines offer up to 100 or more paylines. Penny Slots: Penny slots are designed for players on a tight budget. These machines accept low-denomination coins or bets, typically starting at one cent per line. They are an affordable option for those who want to extend their playtime.

These machines allow for significantly higher bets per spin and offer the potential for larger payouts. Branded Slots: Branded slots feature popular themes from movies, TV shows, music, and other entertainment franchises. Examples include "Game of Thrones," "The Walking Dead," and "Star Wars." These machines often incorporate familiar characters and soundtracks into the gameplay. Skill-Based Slots: Skill-based slots are a newer addition to the casino floor. They require a level of skill or strategy to win, rather than relying solely on luck. Players may need to complete tasks or mini-games to earn prizes. Reel Grid Slots: Reel grid slots, also known as cluster pays or grid slots, replace traditional paylines with a grid of symbols. Wins are achieved by forming clusters of matching symbols adjacent to each other. Virtual Reality (VR) Slots: Some casinos in Las Vegas are experimenting with VR slots, offering an immersive virtual reality experience. Players wear VR headsets to enjoy 3D graphics and interactive gameplay. When exploring the casinos in Las Vegas, take the time to try different types of slot machines to discover which ones you enjoy the most. Each type offers a unique experience, and part of the fun is exploring the variety of options available on the casino floor. Whether you prefer the simplicity of classic slots or the excitement of progressive jackpots, there's a slot machine in Las Vegas to suit every player's preferences. Are slot machines “rigged” in casinos? The quick answer to this question is no. Players must realize, however, that slot machines are not rigged and feature a house edge. The games pay out a certain amount back to players while the casino keeps a certain amount for itself. That house edge can’t be overcome, so it’s important to realize that. However, playing slowly and within your means can make for real entertainment. The RNG within the slot determines if a spin will be a winner or loser, no matter what a player does. Do slot machines pay out less on the weekends? Answer: No, slot results are based on the RNG and the software within the machine no matter what time of day or week. The machines generate random results and your win or loss is based on a random result. Do casinos put the “loosest” slot machines near entrances? Answer: This is also a myth and the game’s performance is based on the RNG and internal programming. These games are computers and provide random results. Are some casinos due to pay out a jackpot? Answer: This is also a monomer and come machines may pay out jackpots two or three times within a certain amount of time. Other times they may experience a “drought” before paying out. The results are random based on the random number generator. How to get free play in Las Vegas? Free play refers to a slot that a player receives without having to use any of his or her own money. Players can cash in for real winnings with these spins and it’s always worth taking advantage of these bonus spins when they are available. How does one actually get some free spins in Las Vegas or at other casinos? Many properties offer players some free play simply for signing up for the casino’s rewards card, especially some of those located away from the world-famous Las Vegas Strip. A rewards card is always worth getting as well because if you’re going to play slots, table, games, or video poker, you might as well earn points toward some of those rewards. Many properties “comp” players with free meals, hotel rooms, and other prizes depending on the amount they play at the casino and the number of points accrued. Those rewards can also include free play sometimes as well. Players may be rewarded with a certain number of spins or a certain amount toward playing. Any winnings collected during these spins can be cashed in for possibly even bigger prizes. A rewards member may also even be invited to a slot tournament. These are sometimes free or may have a minimal buy-in, and have players competing on the slots in a tournament-style competition. The goal is to beat other players within a certain time limit with a chance at some nice cash or prizes put up by the casino. Click here for further information on slot tournaments. Free play can be a lot of fun and doesn’t cost a player anything with a real chance to win. What is the best time to play slots in Las Vegas? This question may depend on the person. Weekends tend to be the busiest and finding a spot at your favorite slot might be more difficult because of so many visitors looking for some winnings themselves. However, those who like the energy of a busy casino may want to hit the slots in the evening or on a weekend. There may be a bustling energy when visiting a casino during this time. On the other hand, for visitors who like a more subdued feel with plenty of room to roam, the morning or daytime might be a better option for playing some slots in Vegas. There tend to be fewer players during this time, which might make for a more relaxed experience. Earlier in the week can also be a good time to play some slots as well. There tend to be fewer players in town and you may have better access to your slots of choice. There is one thing to remember when it comes to the best time to play slots: the actual games are unaffected by the time of day or day of the week. Slots don’t pay out at certain times over other times. As noted, the computer programming within the slots determines a payout at random. The RNG determines a winner as soon as the “spin” button is pressed, zipping through millions of combinations almost instantaneously. That next jackpot may pay out on Monday at noon, Friday at 7 p.m., or Sunday’s early morning hours at 4:33 a.m. You just never know. When it comes to winning, players have no real insight into what’s the best time to play a slot. Those nice payouts and jackpots come at completely random times. Do casinos get rid of slot machines that pay out too much? Many players may think the casino has stacked the deck against them. In a sense, that’s true when it comes to the idea of the house having an edge over players. However, casinos mostly just want to keep slots on the floor that players enjoy and keep playing. Remember, casinos generally keep a percentage of the entire coin-in to their slot machines. That means they make their money from players actually playing at the slots. That’s why casinos offer players free drinks and the chance at comps like free meals and rooms. The casinos want players gambling and are less concerned with player payouts – property managers know they have the edge in the long term. Those games that don’t receive much play are generally the ones that can be removed. More popular games that are generating plenty of coin-in may be repositioned into better locations and properties may also add more of them. The payout to players is often determined by the slot manufacturer and referred to as RTP (return to player). That’s the total percentage of coin-in paid back to players overall. The higher the RTP, the better the chance of a payout for players. This figure also can apply to casinos, gaming jurisdictions or areas, individual slots, a section of games (such as high limits), and more. Sometimes casinos may even make changes because of player interest. In recent years, many Las Vegas properties have phased out a lot of the nickel slots at their properties. Penny slots have become more popular and replaced many of those former nickel games. Those one-cent slots, however, have numerous paylines and each spin can cost much more than a penny. As TripAdvisor notes: The casinos didn't really mind, because the penny machines have a much lower payback percentage. How often does someone win big in Las Vegas? This may be a hard question to quantify. What may be a large payout to one person may not be the same to another person. Players all across Las Vegas book winning sessions at the slots daily. Players also record five- and six-figure jackpots regularly in Las Vegas as well as in other casinos around the world. It’s important to remember that the house holds an edge over slot players and that’s just a fact players have to deal with. Slots are meant for entertainment and if you book a nice win, so much the better. When it comes to major jackpots in the $1 million-plus range, those are much rarer. These seem to occur a few times a month and make headlines when they happen. But winning at that level certainly isn’t the norm. As noted, these payouts generally come on progressive slots where players play at higher limits with the maximum bet in place. These may offer the opportunity at bigger payouts but can also eat away at a player’s bankroll. How do I pick a slot machine to play in Las Vegas? Picking a slot machine is dependent on a player’s mood or interests. There is something for everyone and every taste – from modern machines featuring pop culture to classic games with lucky symbols like 7s, fruits, and more. Those who like to cash in on frequent spins will look for games offering a low variance of payouts. That means they pay out small and medium payouts more frequently while the larger payouts are rare. Higher volatility slots tend to pay out less often but often larger payouts when they deliver a win to a player. There are numerous online sources to check out some of your favorite slots and how they stack up in these areas. Considering RTP is also a good idea and there are numerous online sources, including slot manufacturer websites, that offer this type of information. A higher RTP means more money is paid back to players and you may have a better chance at winning. There are numerous online sources available to check out various Vegas casinos’ RTP as well as those percentages for individual games and areas. Strategies and Tips for Maximizing Your Vegas Slot Experience While slot machines are primarily games of chance, there are a few strategies and tips you can consider to maximize your enjoyment and potentially increase your odds of winning in Las Vegas: Understand the Odds: It's essential to recognize that slot machines are designed to be random, and outcomes are determined by a random number generator (RNG). Each spin is independent, and past results do not affect future spins. This means there is no guaranteed strategy to beat the slots. Set Win and Loss Limits: Before you start playing, establish both a winning and a losing limit. Decide on a percentage of your bankroll that, if reached, will prompt you to cash out. Conversely, set a limit for losses at which you'll walk away. Stick to these limits to help manage your bankroll effectively. Choose Machines Wisely: Look for slot machines with higher RTP (Return to Player) percentages. RTP represents the average amount of money returned to players over time. Machines with higher RTPs generally offer better long-term odds. Casinos may post this information for some machines, but you can also find it online. Play Max Bet on Progressive Jackpots: If you're playing a progressive jackpot slot, consider betting the maximum amount, as this is often a requirement for a chance to win the progressive jackpot. While it may be more expensive per spin, it's the only way to win the big jackpot. Manage Your Bankroll: Stick to your budget and avoid chasing losses by increasing your bets. Remember that slots are designed for the casino to have an edge in the long run. Avoid overextending your budget to prolong your playtime. Take Advantage of Player's Club Rewards: Join the player's club at the casino you're playing in. Membership often comes with perks like free play, discounts on dining and entertainment, and access to exclusive promotions. Even if you're playing slots casually, these rewards can add up over time. Try Different Machines: Don't be afraid to switch machines if you're not having luck on one. Slot machines operate on RNGs, so each spin is independent. A new machine may bring a change in fortune. Time Your Play: Some players believe that playing at certain times of the day or on specific days of the week can improve their chances of winning. However, these notions are generally based on superstition and not backed by solid evidence. Practice Responsible Gambling: The most important tip of all is to gamble responsibly. Set strict time and budget limits, and never gamble with money you can't afford to lose. If gambling becomes a problem, seek help immediately. Enjoy the Entertainment: Remember that slots are meant to be entertaining. Even if you don't win big, enjoy the thrill and excitement of playing. If you're lucky enough to hit a jackpot, it's a bonus! While there are no foolproof strategies to consistently win at slots in Las Vegas, these tips can help you make informed decisions and enhance your overall experience. Keep in mind that slots are games of luck, and the most crucial aspect is to have fun while playing.

Beyond simply offering plenty of entertainment, slot machines offer a chance at a nice payout and that’s the overall goal for most players heading to a casino to play or even those looking for some action online. Line up those reels in just the right combinations and a payout will be heading your way. Players dream of hitting a major jackpot or even a big winning session. Slot payouts vary from game to game, but having a general idea of how they work can make that slot machine session a bit of a better experience. This article offers you everything you might want to know about slot payouts. Slot machine payout schedules and paylines Players new to a slot machine may be a bit confused with so much going on – from spinning reels and the numerous symbols to bonus games and pay lines. There’s a lot to keep up with and it can all be a bit overwhelming. The good news is that today’s modern computerized games keep up with all the payouts and intricacies for you. However, having a general idea of what’s going on when that machine cranks up can add to your experience and help you know how your gaming session is going. Here are a few terms to become familiar with before dropping a few bucks into a game or playing slots online. Payout – This is the term used to describe the number of credits a player receives when the symbols on the machine line up in a certain winning combination. These can vary widely from small payouts that may not even equal the amount you bet on a spin-up to mega jackpots. Payline – These are the lines used across the front of the reels to determine winners. Most early machines only used a single payline across the front of the reels. Today’s games now offer numerous ways to win with pay lines often crisscrossing wildly on the reels. Having more pay lines offer players more ways to win. Pay Table – This is the table that displays how much a player can actually win when certain combinations appear on the reels. Players will find a table going from the lowest payouts at the bottom of the table rising to the largest jackpot payout at the top. These are also divided vertically by the amount bet from the left (the lowest) to the right (the highest payout). The more a player bets per line, the larger the possible payout. Credits/Coin-in – This is the term used for the amount of money deposited into a machine. Your money is usually listed as credits somewhere on the machine, allowing you to track your wins and losses. Coin-in refers to the amount of money in a machine as well, although coins aren't really used in slots anymore. Ready to up your slots terminology game? Read the full article now! A player dropping some money in a machine has numerous options now when playing a slot game. You can determine the number of pay lines you’d like to play as well as the amount of bet per line. Some slot machines allow players to bet as little as one cent per line. With many lines in play, however, the total amount wagered can be much more than that. How and when does a slot machine payout? As noted above, slot payouts are based on how the reels line up but that itself is determined by the machine’s RNG (random number generator). The software inside the machine predetermines a random outcome each time you press the “spin” button. Today’s slots are completely computerized and no longer function based on mechanical inner workings. This ensures that every spin is completely random. Obviously, the odds are much longer for hitting the combinations with the largest payouts. Those lucky enough to hit wins on the top of the paytable can expect some major six-, seven-, and even eight-figure jackpots. There are a few myths that some players hold when it comes to payouts. Here’s a look at a few of those: A slot machine is “due” to pay off – This notion that a game that hasn’t paid out in a while should pay off soon isn’t correct. A payout is based on the RNG and is completely random. A machine paid out recently so it won’t pay out again soon – Again the results of a spin are completely random. There’s no reason that a slot that recently paid out a nice amount won’t dial up another win soon. “Hot” and “cold” slots – The idea that slot machines payout based on a general outlook or certain disposition is also untrue. The RNG determines all payouts on modern machines and randomness rules the day. Which slot machines have the best payouts? Everyone playing a slot is hoping for a nice or maybe just a winning session. Payouts are based on the RNG, as noted earlier, but there are a few things to remember when it comes to trying to find a machine with a better chance of winning. A few key terms regarding this include: RTP (return to player) – This is the amount returned to a player in a certain game. Payout percentage – This is the percentage that a machine or a property itself pays back overall to players. Progressive jackpot – This is a jackpot awarded among machines linked together in a certain area or jurisdiction. These award the massive jackpots that can make major headlines. A higher RTP means a player has a better chance of winning. Payout percentages offer some insight into how much money is being returned to players on a certain game. Some properties and individual games may get over 95%, meaning that the house is keeping, on average, only about 5% of all money put into machines. Those looking for a chance at a massive jackpot will want to play a progressive slot. A small amount is removed from each wager and funneled into the progressive jackpot pool. Those lucky enough to hit the best of winning spins will find massive payouts. However, it’s important to note that only those playing the max bet on most machines have an opportunity at the progressive jackpots. When it comes to paying out jackpots, not many beat the Wheel of Fortune line of slot machines. The games have paid out more than $3 billion since their launch in 1986. How to find the payout percentage on a slot machine Looking at the payout percentages of an individual game or property will help you find machines that may offer the best chance at booking a win. These are often easily available online and you can decide which games might be worth dropping a few dollars in. There are numerous online resources for checking out the payout percentages for casinos, individual slot machines, and even online slots. This allows players to determine which properties and games offer the best chance of winning. Here’s a look at some resources to check out: American Casino Guide – offers payout percentages for all U.S. states Compensation Advisory Partners – a detailed on using payout percentages Slot machine screen – some countries require payout percentages posted right on the machine’s screen Manufacturer websites – many slot developers post their games’ payout percentages right on their websites Beyond these, some individual gaming commissions and control boards also track payout percentages and make them publicly available online. Online slot payouts Players looking for some slot play right from the comfort of their own homes also have some nice chances at some winnings. Some platforms offer numerous games, such as at Jackpot Party, and even progressive jackpots. Manufacturers are now moving beyond the casino floor and offering their titles in numerous formats including in real-money online gaming options, free-to-play gaming apps, and social media gaming options. “That’s where the world is trending because in iGaming, particularly in the United States, the land-based operators are getting digital licenses, and they want to provide their player's 360-degree access to the games that they have,” Scientific Games CEO Barry Cottle told the Wall Street Journal. Online slots offer numerous limits and gaming styles as well and you can play whenever you’d like without the hustle and bustle, travel expenses, and smoking that might be associated with a trip to the casino. Most of all the aspects involved with playing at a live casino also apply online. Payout percentages are also available for numerous real-money online slots as well. Those offering better payout percentages should be moved to the top of the list. Those not paying out very high may want to be disregarded. As at a brick-and-mortar casino, a little research may give you a much better shot at cashing in.

Any gambler who’s watched a vintage movie about Las Vegas has likely noticed the iconic mechanical slot machine. These traditional slot machines, unlike today's games which rely on a random number generator, operated using tangible moving parts to determine outcomes. Charles Fey from San Francisco is credited with inventing the very first mechanical slot machine in the late 19th century, aptly named the "Liberty Bell." Since its introduction, slot machines have evolved with various technological advances. Yet, for many years, players' fortunes depended on the intricate mechanics of these beloved machines, where wins and losses were determined by gears and levers rather than digital computations. Keep reading to find out a bit about how these mechanical slot machines worked and if they can be found for playing today. How Do Mechanical Slot Machines Work? Most slot players take the act of popping a few dollars in a slot machine or opening up their mobile phone or laptop to spin some reels for granted. It's pretty easy to get in on the action and modern games feature plenty of “bells and whistles” – from high-definition video with mind-blowing graphics to cinema-style sound effects to easily-changeable betting options. But these types of options weren’t always the case. Early machines featured single denominations of stakes and very few bells and whistles (although bells were a common symbol on early machines). Despite these limited options, early slots were highly popular with gamblers. Machines are the main draw and gambling revenue drivers for most casinos around the world. “There has never been any other gambling device which has produced such enormous profits with so little effort on the part of the operator,” Scarne’s New Complete Guide to Gambling notes. The author adds: “The slot machine is the only mechanical device with a mechanical banker that collects losing bets, pays off winning bets, and makes fewer mistakes than any human dealer in any casino banking game.” Early machines were manufactured in machine shops and made use of mechanical gadgets instead of techno-wizardry, although there definitely was some skilled engineering to make these gambling devices work. Many of these classic games made use of typical machine-style components including: a cabinet (often metal in the early days) to encase the mechanics gears levers metal shaft to support the spinning reels notched discs kicker connected stoppers Classic machines may vary a bit, but this is the general idea of how the mechanical inner workings of a slot machine work. A metal shaft is a key part of the machine’s functions by supporting the reels (usually only three on older machines), which display various symbols and signify a certain action such as a win, loss, or jackpot. The shaft is connected to a handle protruding from the machine (hence the nickname “one-armed bandit”). Some modern machines feature a handle as well, although they only activate the slot’s computer software. But in these older machines, the handle actually worked to get the mechanical reels spinning and in motion. A braking system brings the spinning reels to a stop to signal a win or loss. Later machines also made use of sensors to enable payouts based on the position of the reels. More advanced mechanical reels eventually also used coin detectors to initiate the game after a coin was inserted into a “slot” – giving the games the name “slot machines.” This mechanism released a brake so a player could move the handle and go for a spin. Here are a few of Jackpot Party's most famous Vegas slots: Click here to uncover our selection of free slots. What is the Kicker and Stoppers? There’s a bit more to this mechanical process with devices called “kickers” and “stoppers” playing a major role. The three reels on the central shaft also house three notched discs. A second shaft supports the slot kicker. This piece is made up of three paddles that intersect with and push against the disc notches. This second shaft also supports several connected stoppers, which protrude into the disc notches. The kicker and stoppers are joined to springs, which lock them in a “standby” position. When the handle is pulled, these are released until they come to a stop and the reels display that spin’s results. Line them up just right and some slot token or cash are headed your way. The actual specific mechanics of the machine varied by manufacturer, but as noted, this is the general idea of how mechanical slots work overall. It seems as the world became more industrialized and new manufacturing processes gained favor, creating a machine that mixed entertainment and gambling just seemed inevitable. Who knew how immensely popular these games would actually become? “With the emphasis on streamlined production and mechanization that came with the Second Industrial Revolution in the late 19th Century, it was only a matter of time before someone invented a machine that could help people gamble faster and more efficiently,” author David Schwartz notes in Roll the Bones: The History of Gambling. Which Pays Better, Video or Mechanical Slot Machines? Part of the fun of playing a slot is the hope that a nice win is heading your way. But cash payouts weren’t always the case. Charles Fey invented the first coin-paying slots in San Francisco in 1895. Earlier machines were more mere amusement devices and paid out prizes such as: cigars chewing gum candy more free spins on the machine free drinks But Fey’s machine revolutionized the gaming industry, transforming this amusement device into a gambling slot machine. His first machine, known as the Liberty Bell, paid out 50 cents when three bells lined up across the three reels. Slots can now be found in casinos throughout the globe as well as online on real-money gaming platforms and in social media mobile gaming options. Gaming options have changed dramatically but the general idea that payouts come via finding fortuitous luck on those spinning reels remains. Obviously, as advances were made, payouts advanced beyond that initial 50-cent win on a Liberty Bell. Players could wager higher denominations and also win on multiple lines. Modern video slots offer much easier ways to win at much higher denominations. However, players must also be willing to wager more per spin because of so many paylines now available to players. Modern slots also offer the chance to win progressive jackpots as well, which can reach staggering sums. These are reached by games being linked across numerous locations and jurisdictions. A small portion of each spin is put into the progressive payout pool and players getting extremely lucky can take all or even a smaller share of that total. In general, players now have many more opportunities to win on a video slot machine or a game with spinning reels but also using modern software and technological engineering. How Do Mechanical Slots Produce Random Results? The mechanics of a mechanical slot help produce random spins based on the actual spinning of the reels. The kicker and stoppers eventually help bring them to a stop as the reels begin to slow. Is this truly random? That depends on one’s perspective. But in the age of computer software, probably not a perfectly random outcome. The mechanics of these games may have favored certain results occasionally but manufacturers were working with real machine parts and worked to make these results as random as possible. Gaming commissions also worked to make sure these were fair games. This is much different than modern slots. These games make use of a random number generator (RNG) to predetermine an outcome before a player even spins the reels. The software predetermines the outcome based on slot machine algorithms for a completely random result. Modern slots are much more computer and software than an actual machine. How to Fix Vintage Mechanical Slot Machines? Many people love the feel of old mechanical slot machines, but sometimes they can have problems. Here's a simple guide to fixing the most common issues: Safety First! Before diving into repairs, always remember to unplug the machine or ensure it's not connected to any power source.

Solution: - Open the front panel using a slot machine key or a suitable replacement. - Carefully remove the coin mechanism from the machine. - Inspect for foreign objects, bent coins, or debris. If found, gently remove them. - Check moving parts for any visible wear or damage. If worn out, consider replacing them or seeking professional help. Stuck or Non-Spinning Reels: If your reels aren’t spinning, the cause might be a broken or misaligned spring, or an issue with the internal gears. Solution: Carefully remove the machine's back panel. Examine the springs connected to the reels. Replace any that appear stretched or damaged. Check the internal gears. Clear any debris or accumulated dirt using a soft brush. If gears appear worn out or damaged, sourcing replacements might be necessary. It's advisable to consult with a specialist if you're unfamiliar with the gear system. Non-Functional Pull Lever: If the lever isn't working, it could be due to a disconnect between the lever and the internal mechanism, or it might be broken. Solution: Open the side or back panel to access the lever mechanism. Check for disconnections or breaks in the linkage. Reattach or replace as necessary. Apply a light lubricant to the lever joints to ensure smooth movement. Misaligned Payout System: Sometimes, the machine doesn't release coins even after a win. Solution: Open the machine's front or back panel. Examine the coin release pathway for any obstructions and remove them. Check the payout discs and tubes for misalignments. Ensure they line up correctly with the payout slot. Regular Maintenance: To keep your machine running smoothly: Regularly clean and dust the internal components. Apply a light machine oil to moving parts annually to reduce friction and wear. Always handle internal components gently to avoid causing inadvertent damage.
