Strolling through Vegas's vast casino landscape, it's evident that slot machine themes have evolved to capture imaginations, promising not just wins but a journey into another world. So, next time you're in the City of Lights, which theme will call out to you? How Slot Machine Themes are Chosen Modern video slots have given slot developers much more to work with when it comes to adding unique and interesting themes. Today’s technology allows for better graphics and sounds, which means manufacturers can also add more narrative elements that can appeal to players of all different interests. The number of slots sought out by casinos around the world also allows for plenty of research and development to find what games might appeal to certain segments of the market. As seen above, manufacturers utilize numerous themes to meet player interests and demands. But how do slot manufacturers come up with these games and themes? Cameron Stewart, SciPlay group vice president of U.S. Game Development, experiences this entire process first-hand and says the goal is to find key elements that will keep players interested and coming back for more. Elements of theme, gameplay, bonus features, graphics, and music all combine to grab players and keep them spinning those video reels: “Slots for me have always been the world's greatest puzzle,” Stewart says. “With millions of outcomes, themes, and components, the experience for the player is limitless. This will always keep the player highly engaged in the story, wondering what's next!” Companies conduct significant market research to determine what games might work best in the marketplace, according to Rise Up Labs. Much more goes into creating a game than just considering a certain theme. During this process, companies consider concepts like these: Game idea – Have other companies created a similar game or used the idea before? Trends – Is the game idea following recent trends in the industry or the general culture? Languages – Does the idea fit multiple regions or feature diverse language requirements? 2D, 3D, or Virtual Reality – Which medium fits best with the target audience? Cost – Does the game fit within a development team’s budget? Some of this is easier said than done. Numerous other factors must be taken into account including market trends and player preferences when determining which themes seem to be working with players. Gauging the success of other games can be a guide in this. A company with an idea for a game may also not be scared away if another manufacturer already used a similar theme. Piggybacking on that success may give players a similar option and find success as well. Some developers also reach out to consumers directly to see what types of games and themes interest them the most. “There are myriad ways to conduct market research for your slot game,” Rise Up Labs notes. “One way is through surveys. So, if you or your business already have customers, you can conduct surveys among them. For example, you can ask questions like if they would like to play your proposed slot game. What features do they want? As a result, you can gauge some of the requirements.” Pop culture is one recent trend that seems to be working across the spectrum of the slot machine world. As video and graphics have improved, developers have been able to incorporate video clips and music from shows and media that resonate with players. Using that nostalgia angle has been successful for many developers and companies have created slots using a wide range of pop culture icons. That has included musical acts like Ozzy Osbourne and Guns N’ Roses, television shows like the Addams Family and Baywatch, movies like King Kong and Jumanji, and numerous others. Players love the nostalgia of these games and connect well with players who may not only enjoy some of their favorite movies but perhaps also slot machine versions as well. Some of the pop culture areas available in the slot machine world include: Movies Television shows Traditional video games (such as Tetris Super Jackpots, available at Jackpot Party) Stage shows (such as Cirque Du Soleil Kooza, available at Jackpot Party) Cartoons Books Comics Not all themes have worked out well, however. While pop culture connects in a positive way with many players, others don’t always create that same sense of positivity. Using religion in gaming isn’t always a good idea and a game called Lakshmi’s Gold experienced this in 2012. The game featured Hindu religious symbols as well as gods and goddesses, including the important goddess Lakshmi. Many Hindus protested using the religion in a slot machine game with Rajan Zed, president of the Universal Society of Hinduism, calling the game “highly inappropriate.” The developer ultimately discontinued the game. Certain aspects of the pop culture theme don’t always work as well. The TMZ gossip show and website may attract plenty of viewers and readers looking for scoops on famous celebrities but didn’t appeal to slot players. The game never really gained much traction, however. Players don’t like mixing their gossip with their slot play. Designing Slot Machine Themes Once a theme for a new slot machine has been determined, manufacturers must then go about actually designing the game. That includes technical issues, programming software, creating the graphics, adding a narrative arc if needed, and making the game visually appealing. This can apply to both live and online slots as well. “A preliminary version in the online slots development process is crucial,” Game Industry News notes. “The process involves creating a skeletal outline to test software compatibility accuracy and lessen errors to insignificant levels. The team’s focus in this stage is limited to crucial aspects only. What follows is the primary version of the entire project. “User experience in game development strives to offer game twists and moves that a player can easily relate with, given his past interactions. Modern casino developments like gamification, retro vibes, animations, celebrity-inspired slots, and mobile optimization take center stage here. This stage is tricky as the whole team must use research-backed data. The data helps identify the ideal characters and how they transition across scenes.” In recent years, video and animation have been used more and more in slot machines. This offer is not just a way to connect with players but also a way to add interesting, unique features that certainly weren’t available when mechanical reel slots ruled the day. The games are no longer confined to static symbols like fruits, bars, 7s, and other vintage symbols. “The presence of dynamic characters also allows for more complex storylines, which would not be possible with static symbols alone,” AnimationXpress.com reports. “Developers can use these figures to craft unique stories and objectives within the game, creating a narrative that keeps players engaged throughout their gaming experience. This narrative is further heightened by the rich visuals, sound effects, and other immersive elements that dynamic characters bring.” The Wheel of Fortune slot phenomenon shows how the use of a popular theme, in this case, a well-loved television show and a major part of pop culture, can be combined for a massive hit game. The slot takes advantage of the popularity of the show and also offers a real quality design with numerous other versions ramping up the fun. Wheel of Fortune was also one of the first licensed games in the industry. The Wheel of Fortune line of clots celebrated its 25th anniversary in 2021 and that came with some pretty impressive numbers. After a quarter of a century of spinning reels and spinning wheels, the games have reached quite a few major accomplishments: 1,100 jackpots of more than $1 million. Awarded more than $3.3 billion in jackpot prizes. IGT has developed more than 250 versions of the game. Paved the way for hundreds of additional licensed slot games to appear in land-based and digital casinos worldwide. Top Slot Machine Themes of All Time There are numerous slot machine themes for players to choose from and developers continue to offer newer games with even more innovations. There is something for every type of player, but a few themes seem to stand out. Television Shows – As noted, Wheel of Fortune is the most successful of these and remains highly popular still after almost three decades. Game show slots make use of pop culture to connect with players who may be fans of a particular show. Movies – Like television shows, these theme seems like a natural way to connect with players. These games usually feature videos from the actual films to enhance the experience. Animals – Whether in the wild or as pets, players tend to favor these types of games and they remain very popular. Many of these games, such as Buffalo and Wolf Run, offer a look at nature that transports players outside the casino and into the wild. Casino-style, Vegas classic, and vintage slots – These offer a bit of throwback to classic Vegas and casino gaming. Players will see traditional symbols like fruits, bars, 7s, and more but usually with a modern twist. A few examples of these types of games include Blazing 7s and Aftershock. Chinese and Asian slots – This theme remains hot all around the world as players seem intoxicated by games featuring imagery from the Far East. These games often feature symbols related to luck, such as dragons, cold coins, and even some cute babies on occasion. Popular titles with this theme include Fu Dao Le, Jin Ji Bao Xi - Endless Treasure, Dragon Spin, and numerous others. There is much more that goes into creating a successful slot machine than just selecting a popular theme, however. Manufacturers still must create games that appeal to a broad base of players. This includes creating compelling narratives, fun gameplay, nice bonus features, and so much more. Slot Machine Themes of the Future Considering the numerous slot machine themes available, players may be asking “what’s next” when it comes to the world of slot machines. With continuing advancement in technology, there seems no end in sight for slot manufacturers’ creativity. Obviously predicting the future, but gazing at the crystal ball with some realistic expectations may allow for at least some reasonable predictions on where the game may be headed in the future. Here’s a look at what might be in store in the future when players visit their favorite casino or when heading to an online gaming platform. Virtual reality – Tech firms have begun embracing virtual reality in a big way and it seems likely that this new technology will also head to a slot machine cabinet or online gaming platform at some point. This may offer players a chance to actually be part of the game, play in a unique setting away from the casino, or some other angle that would fit well for slot play. Some gaming companies, such as PokerStars, have already moved into this space. Holograms – This offers another unique technology that could be embraced by the slot industry. Hologram music concerts have become normal in recent years, allowing long-passed artists to be “revived” to perform again. Does it seem out of the realm of the possibility that the technology could be used to enhance bonus games or other slot features? Probably not. Video games – Traditional video games remain immensely popular and as younger generations get older, it seems likely more and more manufacturers will embrace traditional video games with a slots twist. Some companies are already doing this with skill-based games that seem more similar to traditional arcade games. Others are licensing popular and classic video games like Tetris and Pac-Man. Cabinet innovations – Emerging technologies possibly could mean complete changes and additions to some of the most popular slot machine games. This could include advanced three-dimensional technology and other enhancements as well as completely different approaches to how to make use of the technology. Mobile and online slots – As manufacturers continue to up their game, look for more innovation in online slots including platforms like Jackpot Party. Companies continue to enhance their offerings and ramp up even more dynamic slot themes. Pick and enjoy our fantastic slots from the options below: Click here to explore all of our free slots. Conclusion Unique and popular themes allow slot companies and casinos to better connect with players.

Developers are constantly working to meet that demand. Modern video and sound technology have made slots a real entertainment option similar to movies, television, and video games. This medium is also now encompassing those elements as well by way of unique and interesting themes including licensing popular titles and characters within the world of pop culture. Slot themes can connect with players in a few ways including: Offering a sense of nostalgia that connects with fond memories. Showcasing a pop culture interest of the player, such as a favorite TV show, movie, or musician. Offering a popular type of narrative or topic, such as history or the Old West. Appealing to a sense of luck or good fortune, as seen in popular Asian or Irish-themed slots. Giving players unique features and bonus games that only enhance or add to the theme’s fun experience. Adding interesting technology that amplifies the theme and gameplay. Players don’t even have to head to a casino to experience some of these slot theme offerings – or wager any cash at all.

Walk into almost any casino and you’ll quickly notice that slot machines are the most popular gambling options on the property. Many major casinos offer thousands of these high-tech computerized games for players to choose from. This wasn’t always the case, and slots are a fairly recent phenomenon when it comes to the history of casino games. Some games, such as roulette and blackjack, trace their roots back centuries. However slot machines were created in the United States less than 200 years ago. Keep reading to learn the complete history of slot machines. 1 – Forerunners to Slot Machines A uniquely American invention, one slot machine forerunner came out of Brooklyn, New York. A firm named Sittman and Pitt of Brooklyn patented a gambling machine in 1891 that featured five drums showing 50 playing card faces. This machine was based on poker and gained a degree of popularity with bars around the Big Apple hosting the games. Players dropped a nickel in the machines and pulled a lever. Like a traditional slot machine, the reels and the player hoped for a nice poker hand. However, unlike modern slots, there was no direct payout from the machine itself. Winning players might earn a free beer for a big pair and higher hands might even pay out more, such as a box of cigars for a royal flush. However, what a player could win was completely up to the bar that hosted the game. Even during those times, there was always a house edge because there were only 50 cards. The 10♠ and J♥ were removed, making it more difficult to make bigger hands. The poker-based play and results proved to be the downfall of the Sittman and Pitt machine. Because of so many possible winning combinations, there was no feasible way to make a machine that featured automatic payouts. As a result, players often had to rely on bartenders or establishment owners to distribute their winnings manually, which led to inefficiencies and inconsistencies in payouts. The sheer popularity of coin-based entertainment also proved to be popular during this time. Vending machines dispensing holy water, invented by mathematician and engineer Hero of Alexandria, dated back to 1 A.D. in Roman Egypt. A person visiting a temple could insert a coin and the machine would dispense a certain amount of the purifying liquid, making sure that the water would last longer for more Romans. By the 17th Century, vending machines were found throughout the UK. These machines offered players a chance to win tobacco and snuff. The popularity of vending machines would continue in the coming years, eventually offering cigarettes, sodas, snacks, and other items for sale after dropping some coins (and eventually paper currency) into a machine. In the 1890s and 1900s, penny arcades became popular entertainment options as well. As the name implies, players could see short movie-like clips, have their fortune read, play non-electrical pinball, and other options. They also eventually included early slot machines, which were often referred to as fruit machines at the time. Penny arcades enjoyed tremendous success and popped up in nearly every town, small and large, across the United States,” AmericanAntiquities.com notes. “The most successful and profitable game was the fruit machine, or as we call it today, the one-armed bandit, which at one time or another was once banned almost everywhere. As penny arcades became more popular, slot machines quickly joined the coin-operated entertainment. Decades later, they are still extremely popular. 2 – The First Slot Machines Eventually, someone would work to perfect a machine that featured coin play, spinning reels with symbols, and automatic payouts. In 1887, San Francisco’s Charles Fey became the man to make all that happen. The German immigrant created the Liberty Bell, the first real slot machine, which he mass-produced and featured three vertical reels. The term “slot machine” also came into the lexicon because of his invention. Players inserted a nickel into a “slot” on the machine to initiate the reels. Just 29 years old, the mechanic built a machine that would eventually dominate the gaming industry. Liberty Bells were the first machines to offer automatic payouts, rewarding winners with a nice jackpot in nickels. Certain combinations could also reward players with free cigars or drinks. This was a bit of a precursor to today’s “comp” system found in most casinos. Those original machines featured three reels and symbols: fruit bells playing card symbols horseshoes stars Many of these symbols can still be seen on today’s slots as well, more than a century later. Fey manufactured the games in his machine shop and installed the games in bars, saloons, and gambling halls around San Francisco. He reached 50/50 revenue-splitting deals with the property owners. Those early games included some masterful engineering and craftsmanship and would eventually go on to revolutionize the gaming industry. They also became extremely popular and could be found all across the city. State officials began to take notice, apparently, and led to some changes in gaming laws. Little could slow down San Francisco’s growing slot industry, not even the catastrophic 1906 earthquake until a 1909 law made slots unambiguously illegal,” author David Schwartz notes in his book Roll the Bones: The History of Gambling. “By then, city authorities had gotten nearly $200,000 each year in taxes on the city’s 3,200 slots. Despite that, slots continued to flourish in a “gray area” with the fruit on the machines representing gum flavors. However, winners could still receive cash payouts. A bit of “creativity” could also help, as the country still retained a bit of the “wild west” mentality. A friendly payoff to the local police or judge almost always guaranteed that the slot rite operator could place machines in public places with little fear of official interference,” Schwartz adds. “Cheating, theft, and hijacking by criminal gangs were the biggest obstacles operators faced. Mechanical improvements eventually made cheating and theft less of a concern, and many operators began providing a cut of the profits as “protection” to avoid potential hijackings. Despite the popularity of his machines, however, Fey still had limited production capabilities in his machine shop and couldn’t meet demand. Despite his slots’ success, he couldn’t expand beyond California. That’s where Chicago’s Stephen Harper Mills stepped in. In 1907 his Mills Novelty Company began manufacturing his machines. These games featured additional fruit symbols and also featured black bar icons that are even still seen today. These “Bell-Fruit-Gum machines” initially awarded winners with chewing gum as a way to get around restrictions on some of the recent bans on gambling. However, savvy bar owners would often simply pay winners in cash. Those gum payouts are believed to be a unique part of slot machine history. Many experts believe the symbol was originally a piece of chewing gum from the Mills Novelty Company. But when those gum payouts went away, the logo was changed into the bar logo still seen on some modern slots. Slot machines continued to flourish up to 1910 and Mills helped locate them in locations around the country. However, the burgeoning industry faced some headwinds. Government officials sought to regulate and in some cases outright ban, slot machines and other forms of casino gaming as well. Despite those efforts, gamblers continued to embrace slots – whether legal or not. 3 – Expansion and Growth By the 1950s, Nevada was the only state in the U.S. offering legal casino gaming. A slot player might have to travel to Las Vegas to play some of their favorite games. These years saw considerable growth in the city, which had only 44,600 residents but more than eight million visitors each year. In 1954, the city saw gamblers dropping $200 million into Sin City casinos. In the 1950s, gamblers could head to properties like the Silver Slipper, the Desert Inn, Binion’s Horseshoe, the Sands, Golden Nugget, the Showboat, Riviera, and others. Slot machines became a bigger and bigger part of the Vegas casino business and this period also saw some major advancement in the games. Some of those that came in the 1950s and ‘60s included: multi-game payouts four-reel machines Multiple paylines electromechanical games The early multi-game payout machines were a bit different than what slot players see today. In essence, three games were attached. A gambler would insert a coin in each machine and be capable of winning on each machine individually or when three bars showed up on the paylines in any of the three machines. Because of their size, the slots were often referred to as “monsters” or ”Frankensteins” and ultimately weren’t very popular. These games eventually faded away, but at least served as a precursor to other multi-payout games that would come on the market later and prove to be much more popular with players. Adding more reels and paylines offered casino goers more entertainment value and more ways to win. Mechanical reels were also being replaced by electromechanical games. Bally Manufacturing started the trend in 1963 with the first fully electromechanical slot machine. That original game was called Money Honey and brought about a major transformation in slot production. Like Henry Ford’s Model T, this three-reel electromechanical slot machine broke new ground, forever changing the landscape of the gaming industry,” the company notes on its website. “The two innovations that the game brought to the casino industry were its reliable electronically controlled construction and the incorporation of a ‘bottomless’ motor-driven payout hopper capable of automatic payouts of up to 500 coins without the use of an attendant. For the next 12 years, Money Honey in its many variations would become the flagship game of Bally Manufacturing’s slot machine division. Honey Money became such a hit that other slot machine manufacturers began debuting their electronic games. This also meant that the lever traditionally used to spin mechanical reels became more of a symbolic device than a real part of setting those reels in motion. But the electromagnetic reels sped up the action, added excitement, and also created a more random game. Multiple coin games were also introduced and grew in popularity throughout the ‘60s and ‘70s. Players could score even bigger wins (and potentially losses) by wagering more coins. Progressive jackpots were also added during this period and both of these features remain key parts of slot machines still today.

The first video slot hit the market in 1963 with the debut of a game called Automatic Blackjack. While that game wasn’t technically a slot, the technology was also included in slot machines as well. The games weren’t particularly popular but the video poker version attracted plenty of attention in the ‘70s and ‘80s. That would help lead to more video slots in the coming year and they eventually gained a foothold and took up more and more casino space. The first progressive jackpot slot also debuted in Nevada. IGT’s wide-area progressives combined the instant gratification of slots with the life-changing jackpots of lotteries – a heady combination unimaginable when the first slots were crafted,” Schwartz writed in Roll the Bones. By the 1990s video slots were taking over more of the industry and the first multi-screen game was in 1996. Players began seeing the use of more technology that Charles Fey probably could have never imagined. More games featured higher-quality video, sound systems, touch screens, card readers to track player reward card points, and more. Random number generators were also introduced to make sure each spin of the reels was guaranteed a completely random event. The 2000s saw coin-operated machines fade away as machines began allowing players to easily insert paper currency instead. Machines could also pay out in casino vouchers instead of slot tokens, which could also be used to insert into other machines. The multimedia aspects of slots ramped up beginning in the 2000s. High-definition screens and sound became more prevalent as did various screen sizes and types. Slot developers began experimenting with skill-based games as well to try and appeal to younger players more used to playing video games than slots. More themes began being used as well to appeal to a wide range of players – from pop culture to mythology to narrative stories and more. The last few decades were a real period of growth for the industry and slot machines became by far the most popular form of casino gaming. 5 – The Rise of Online Slots With the growth of the Internet in the 1990s, some companies envisioned players being able to play slots and other casino games right from their computers. InterCasino became the first online casino when it launched in 1994. More quickly followed, allowing players around the world to play slots without heading to a brick-and-mortar casino. These games certainly didn’t have all the bells and whistles seen in today’s games. They featured basic design and gameplay, but showed the possibilities of playing online. The games began to grow in features and possibilities in the coming years. When mobile gaming grew in popularity throughout the 2010s, more operators began ramping up online slot offerings for players to check out. Users could play for real money right on their mobile phones or tablet devices. Social gaming sites offering slot play for free, such as Jackpot Party, also became much more popular. Players can check out some entertaining slots right on their phones without spending a dime of their own money. Some enjoy playing these games more than actually visiting a real casino and playing for real money. 6 – Conclusion As technology continues to advance, slot manufacturers continue advancing their games as well. Slots have come a long way from those early games of Charles Fey and Mills Novelty Company. Players now find modern technological games with seemingly something for every interest and bankroll. The entire industry reached a total value of $8.5 billion in 2021 and is expected to climb to $20.1 billion by 2028, according to a report by Branded Essence Research. There seems to be no slowing the popularity of slot machines, both in a live casino and online. Players simply love those spinning reels, lights, sound, and the chance to win some big bucks.
