While they may now be a part of the Scientific Games family, the company is still a vital player with a great selection of games.

Where to Play WMS Slot Machines
Unfortunately, some players may find it difficult to find some of WMS’ games at land-based casinos. Their feature-rich and big machines don’t always have a place in every casino.
New Jersey and Pennsylvania residents may not always be able to find a wide selection of WMS games at their favorite casino. Although, most casinos should still have a few of their popular licensed games along with some of their more compact machines.
Anyone planning a visit can either contact the casino to ask about availability or see whether they have a slot finder or active slot machine list on the location’s website.
Players willing to play online or through mobile devices may have more luck. While some of the more extravagant machines have not yet been adapted, many fun and exciting older games are available for real money play where it’s legal.
New Jersey residents should be able to find a good selection of WMS games in legal online casinos and apps for land-based casinos.
Pennsylvania residents don’t currently have much of a selection, but it should grow soon as more online operators open.
Best WMS Slot Machine Games
The following set of slot machines should let you see the bonus features and designs that make WMS special.
Reel ‘Em In: Big Bass Bucks – Try out an updated version of the machine that started it all. This 5-reel, 20-line slot machine is themed around a relaxing afternoon at the old fishing hole. The game shines with its fun bonus features. Players who trigger one of three fishing themed bonus rounds get to pick an angler, choose a spot to fish and then watch the casts play out to see what cash prizes await. A great slot machine with an engaging bonus round.
Jackpot Party: Ultimate Party Spin – This is another great update to a classic title. This is a 5-reel slot machine with 30 paylines that has variants for both 60s and 70s party themes. The bonus game is a fun twist on a standard pick bonus game. Players get to rapidly pop balloons that appear on the screen for small credit prizes, and the game only stops when they hit a “party pooper” balloon. Players can win up to 3 spins on the big bonus wheel, depending on how many balloons they pop before hitting an unlucky one. The bonus wheel includes more credit bonus prizes as well as 2 progressive jackpots, along with second-tier bonuses that stack to give players extra spins or enhanced spins.
The Flintstones: Welcome to Bedrock – This is one of WMS’ great licensed titles that captures all the fun of The Flintstones. The main game uses 5 reels and 25 lines, but it’s absolutely stuffed with bonus features accompanied by scenes from the cartoon. Any spin can trigger a Yabba-Dabba-Doo feature that can randomly add wilds, add a multiplier, stretch the reels, double the reels or possibly even do a little bit of everything. There’s also a bonus wheel where players can win extra credits, free spins or a free play of the At The Races minigame. This lets players choose between different bets with different odds and payouts with the result displayed as a simulated dino race. Impatient players can also pay to go to the races at any time. Certain casinos may even activate a progressive jackpot feature.
Raging Rhinos Megaways – This is another update to an old fan favorite. This version of Raging Rhinos adds the Megaways feature to make it a 6-reel machine with potentially 117,649 ways to win across the large reels and extra top row. Each spin includes a cascading reels feature to potentially let the winning spins stack. The free spins bonus round is very loaded. Players lucky enough to trigger the bonus will see free spins with wild multipliers and an enhanced cascade feature that adds a general multiplier to the free spin round for every successful cascade.
James Bond: Casino Royale – Another exciting licensed title from WMS. This James Bond-themed slot machine uses the sights and sounds from the modern Casino Royale movie to spice up the game. This 5-reel, 25-line machine includes deep bonus games that give players a shot at winning big credit bonuses or a progressive jackpot. The chip pick bonus game lets players try to find upgraded chips to unlock bigger prizes and literal shots at bonus and jackpot playing cards. The casino bonus uses a card picking game that gives players a chance to unlock special bonus reel arrays along with big multipliers. For fans of other Bond movies, WMS has a few other similar machines themed around Thunderball and Live and Let Die.
Progressive Jackpots and Innovations
Despite only being in the slot machine game for a few decades, WMS has done a lot to push the envelope and make slot machines more interesting.
Their long history of designing great pinball machines and video games proved to be vital for their slot machine development.
Starting with Reel ‘Em In, WMS has created machines that put entertainment first to let players have a good time while they were trying to hit it big.
Their focus on bonus games and impressive designs is clear even today. Aside from interactive bonus games and features with impressive graphics,
WMS has also tweaked its slot machine game designs to better suit different players. They offer “boosted” reels with fewer rows on the left side to make wins less frequent but much richer, but WMS also offers the Megaways designs to give players ways to stack up lots of small, frequent wins.
In general, their focus has been on providing slots that are easy to play with the right mix of big wins and frequent, smaller bonuses to please any player.
The only downside is that this philosophy means that progressive jackpots are a little rarer in WMS games. Elusive big wins don’t fit quite as easily into their games.
They haven’t completely forgotten about progressive jackpots though, especially in their more recent games developed in cooperation with Scientific Games.
Many of their eye-catching banked machines, such as Jackpot Party: Ultimate Party Spin or the new Invaders Attack From the Planet Moolah, do offer two progressive jackpots along with their general credit prizes.
The more recently developed Bond slot machines also include them.
WMS Slots on Mobile Devices
Players looking to enjoy WMS slot machines on iOS and Android are in luck.
Scientific Games generally pushes its subsidiaries to adapt and develop for the online and mobile markets, but WMS was already a leader in the field before the buyout.
WMS has been adapting and perfecting its online slot machines through the WMS Interactive brand using the social gaming site Jackpot Party alongside contracts with legal online casinos across the world.
Many of their games are ready to play on mobile devices. Interested players can find free-to-play versions through apps such as the Jackpot Party app or Scientific Games’ Gold Fish Casino app. Their crisp graphics generally transfer well to smartphone screens. The only exception is their few machines that feature colossal reels, which are probably best left for desktop and tablet play.
Players in states and countries with legal online slots can find real money versions through apps from land-based casinos and regulated online casinos.
Top 3 WMS Mobile Slots
These mobile slots feature fast-paced spins with nice clear designs that translate well to mobile devices.
Elvis: The King Lives – This rock ‘n roll themed slot machine uses a unique layout to give players boosted reels. The game technically features 11 reels and up to 80 paylines. The design uses 8 individual reels to make up two mini 2×2 reels on the left side of the game. The 3 tall reels on the right complete the set. This boosted reels setup typically makes it a little harder to start a line but makes any winning line multiply into dozens of wins. The free spin bonus game is also rewarding. Players get a bonus jukebox spin for extra free spins or credits, and every free spin is enhanced with giant symbols filling the two leftmost reels to make winning just a little easier.
The Cheshire Cat – A topsy-turvy-themed slot machine with a beautifully clear interface that makes each win easy to see. It is a 5-reel slot machine with 40 paylines in play. The twist on the free spin bonus game is what really makes the game interesting. Before the free spins begin, players get a separate spin with the Cheshire Cat to determine whether any bonus arrays are in play and what reels are set as wild for the duration of the free spin round. It’s a great twist on an otherwise fast and simple slot machine.
Frozen Inferno – This magic-themed slot machine puts a very cool (or hot) spin on a typical slots session. The 5-reel, 40-line slot machine switches between inferno and frozen modes in a little gameplay cycle. Wilds lock into place in the frozen mode and roam freely around the reels during the inferno mode. As the spins continue, players slowly add more locked or roaming wilds to the reels until they hit the cap of 5 and trigger a free spin bonus round. The round guarantees 5 wins and slowly flips the game to the opposite mode. It’s a wonderful twist for anyone looking to settle in for a decent set of spins.
The Early Days of Williams Interactive
WMS technically began as an electronics manufacturing firm in 1943. Harry Williams founded the creatively named Williams Manufacturing Company in Chicago, Illinois.
At first, the company provided a variety of simple electronics, including re-designed pinball games, fortune teller machines and other novelties. In 1946, the company designed its first wholly original pinball game, Suspense, which would prove to be the first step to several decades of success in the pinball market.
The company made a name for itself thanks to innovations such as mechanical scoring reels and tilt mechanisms, and it generally thrived through the golden age of pinball across the 1950s and 1960s.
The only big shakeup in this time would be a buyout in 1964 by the Seeburg Corporation, a major jukebox manufacturer.
In 1972, Williams would make a major change to its business with a step into the newly emerging arcade video game market.
While its first entry was merely a derivative of Pong called Paddle-Ball, it wouldn’t be long before the newly formed division known as Williams Electronics would be an industry leader. They would manage to make a big splash with hits like Defender and Joust and enjoyed a successful run throughout the 1980s.
In 1988, they bought Midway from their future slots competitor Bally. While they would eventually sell it in 1998, their 10 years of ownership included the release of legendary games such as NBA Jam and the start of the Mortal Kombat series.
The Move to Slot Machines
The 1970s and 1980s were generally a prosperous time for Williams. Their parent company Seeburg declared bankruptcy in 1980, but Williams was successfully sold to a private investor who put the company on the road to going public.
When the company went public in 1987, they shortened their name down to the now iconic WMS Industries. The company was soon faced with a new challenge though.
As the arcade craze faded away, their pinball and video game divisions struggled.
While WMS would continue to produce pinball and arcade games until near the end of the 1990s, including hits like the Addams Family pinball machine, management knew that they would need to transition into a new industry.
WMS Gaming was officially formed in 1991 to start distributing video lottery machines. The subsidiary pivoted to the distribution of slot machines in 1994 to take advantage of the growing market of Native American casinos that were opening nationwide.
They wouldn’t really cement their place in the slots market until 1996 with the release of Reel ‘Em In. Taking full advantage of their experience making entertaining video games, the game included an animated second screen bonus game that let players pick a fisherman to try and catch a bonus.
This was a revolutionary development for the American market. WMS would continue to produce interactive machines with great graphics including hits like Filthy Rich and Jackpot Party.
The company would build upon this success throughout the 1990s and 2000s by making licensed slot machines.
Their focus on eye-catching games worked well with these well-known themes and the company released dozens of popular slot machines based around major properties, such as Monopoly, Star Trek and the Wizard of Oz.
These hits kept the profits flowing, and put WMS in a good position to target the new online slots market in the 2010s.
In 2012, the company bought Jadestone Group AB and Phantom EFX to add to its online gaming development under the newly formed Williams Interactive name.
WMS had one last major change ahead of it though.
In 2013, Scientific Games acquired WMS in a $1.5 billion buyout. This would put the WMS slot machine catalog under the SG umbrella, along with its former competitors Bally and Barcrest.
The company is far from gone though. WMS still exists as a thriving division of Scientific Games and continues to produce the same engaging styles of slot machines that made them famous.
WMS (short for Williams) was founded in 1943 to produce electromagnetic games and pinball machines. The company became one of the industry leaders during the golden age of arcade gaming, but its influence declined with the industry throughout the 1980s.
Even though Williams’ video game division was tremendously successful in the early 1990s, the company ultimately had to switch to the production of slot machines. WMS gambling products played a key role in pushing the industry into the era of license-based slots, and their revenue skyrocketed in the 2000s.
In 2013, WMS merged with Scientific Games, (SG), and in 2016, it was fully integrated into SG’s corporate structure.

WMS’ strong background in arcade cabinets and video games allowed the company to produce some rather stunning slots in the ‘90s, but the competition managed to catch up in the 2000s and early 2010s.
Modern WMS slots are not inconsequential thanks to features such as a powerful CPU-NXT3 processor, advanced lighting packages, and high-definition displays. Slot cabinets released under this brand are also known for excellent ergonomics, but most of these traits can only be appreciated in a brick-and-mortar casino setting.
As far as online play is concerned, WMS relies mostly on showcasing popular entertainment brands, such as Star Trek, Monopoly, or The Wizard of Oz.
WMS slots: game spotlights
Over the past 25+ years of producing slots, WMS released plenty of quality games for several generations of casino hardware. Some of the most popular Williams slots include Lord of the Rings, Top Gun, Kronos, and Epic Monopoly. Here’s a short overview of three WMS games that are still popular among online casino enthusiasts in 2019:
- KISS– two sets of five reels, 100 paylines. KISS was the first slot to be released with the colossal-reels setup, which means the screen is divided into a five-by-four game and a five-by-twelve game. As expected from a slot that’s based on the oeuvre of a famous rock band, the music and sound effects are absolutely top-notch. The game allows players to choose one out of three bonuses upon hitting three “Shout It Out Loud” scatter symbols. These bonuses include free spins with a payout multiplier, a pick ’em round, and a random band prize reward.
- Zeus– five reels, 25 paylines. Despite some minor graphical shortcomings, such as the uninspired background and simplified animations, this is still one of the smoothest WMS games available on the internet. The popularity of this slot can likely be attributed to its immensely satisfying free spins bonus round, which can be triggered by putting at least three temple scatter symbols on the reels. Every bonus spin comes with a 3x payout multiplier and hitting additional scatter symbols before it completes awards the player with even more free games.
- Alice & The Mad Tea Party – five reels, 30 paylines, and an absolutely crazy package of bonus rounds. Five of these bonus features activate at random and reward players with additional wilds, multipliers, and re-spins. In addition, hitting the feature symbol on the first, third, and fifth reels will trigger the Mad Tea Party free spins. These come with several pick ’em rounds that provide players with an opportunity to extend the bonus or get a higher payout.
Special slots features
WMS is best known for incorporating popular intellectual properties into their slots and for leasing them to land-based casinos instead of selling them. The latter practice doesn’t have a noticeable impact on the overall gameplay experience, but the former definitely matters for fans and casual players.
Despite the crisp visuals and appealing themes, Williams slots aren’t very innovative when it comes to bonus mechanics. WMS’ design team does a good job when it comes to implementing popular features like stacked wilds or free spins, but its contribution to the industry is limited to aesthetics.
Online slots and land-based machines
As mentioned above, WMS produces some of the best cabinets in the industry, especially when it comes to player comfort and special effects that can’t be replicated in an internet casino.
As for the games, the differences aren’t as pronounced as in Bally titles, but that’s mostly because WMS slots tend to feature fewer animations. Still, there are some differences between both versions that are easy to spot.
For example, in the land-based version of WMS’ iconic Zeus slot, the thunderbolt symbol comes with a satisfying set of animations, while in the online version, the same symbol is animated in a rather simplistic manner.
Most of these differences can be explained by the necessity to transform cutting-edge slot machines into apps that can be downloaded to a mobile phone via a 3G network connection.
However, this doesn’t account for some of the simplified and static 2D graphics, especially when it comes to backgrounds. For example, the aforementioned Zeus slot cabinet is visually impressive as a whole. Even the official paint job is consistent with the theme.
Meanwhile, the background for the online version is made up of a bright sky and a golden Greek temple; there really is no thunder in that. On a brighter note, the gameplay is absolutely on-point in both cases, and the symbol designs are consistent between both versions of the game.
Select games and payback percentages
Return-to-Player (RTP) rates for WMS slots tend to fall within the 95% to 96.5% range, which makes them slightly more profitable to play than most IGT or even SG games. The variance is either medium or low, so the payouts and bonus round activations tend to be fairly consistent during prolonged sessions.
- Raging Rhino – 95.9% RTP
- Amazon Queen – 95.9% RTP
- Cool Jewels – 96.1% RTP
- Montezuma– 95.86% RTP
- Kronos– 95.94% RTP
- Bruce Lee – 95.05% RTP
- Jungle Wild – 95.1% RTP
- King of Africa – 95.1% RTP
- Epic Monopoly II – 96.01% RTP
- Crystal Forest– 96% RTP

Williams Manufacturing Company
WMC was founded in 1943 in Chicago, Illinois by Harry Williams. Its first products were mostly electromechanical games, such as Periscope and Liberator. In 1945, the company released its first pinball machine, which was called Flat-Top and was actually a machine made by another company released with Williams’ artwork.
In 1950, WMC produced the first pinball machine with a modern bottom flipper setup. Over the next 20 years, it became one of the top pinball machine manufacturers in the United States. Some of the most popular WMC pinballs designed in this era include Shangri-La (1967), Apollo (1967), Gold Rush (1971), and Space Mission (1976).
Arcade games and pinball
Williams made its first forays into the fledgling arcade gambling industry in the late 1970s, but its breakthrough hit came in 1980 with the release of Defender. Throughout the 1980s, the company released many other influential video games, such as Joust, Robotron, Sinistar, or Moon Patrol.
It also produced many groundbreaking pinball machines, including Gorgar, Firepower, Black Knight, Jungle Lord, Space Shuttle, High Speed, F-14 Tomcat, Cyclone, and Taxi.
In the early 1990s, WMS started focusing on developing pinballs based on popular entertainment franchises, such as The Adams Family or The Twilight Zone, while its recently purchased video game subsidiary, Midway, released several smash hits, including Mortal Kombat and NBA Jam.
Focus on slot machines
Despite WMS’ best efforts, the pinball machine industry was already in decline in the 1990s, and the company was looking for a new source of revenue. In the end, Williams’ executives decided to bet on gambling, and in 1996, the company released its first slot machine, Reel ’Em In.
WMS’ experience in high-tech pinballs allowed the company to succeed in this new market. By the end of the decade, WMS sold Midway and closed its pinball division to focus solely on producing gambling equipment.
Throughout the 2000s, WMS achieved tremendous financial success thanks to its participation slots model, which boiled down to leasing and licensing slot machines to casinos instead of selling them. It also developed a wide range of slots that were based on readily recognizable entertainment brands, such as Men in Black, Star Trek, The Dukes of Hazzard, and Lord of the Rings.
Merger with SG Gaming
WMS continued developing high-quality slot machines, which often came with interesting mechanical features, such as advanced lighting packages or animated mechanical reels. These cabinets were powered by top-shelf hardware.
For example, the CPU-NXT2 platform incorporated a Pentium IV processor and an ATI graphics card. Even though WMS was doing reasonably well in the early 2010s, the company was sold to Scientific Games for $1.5 billion in 2013 and was subsequently integrated into SG’s corporate structure.

WMS management and corporate structure
WMS was a somewhat independent subsidiary of SG between 2013 and 2016 but was later reorganized to become an independent part of its parent company. There’s no distinction between the two as far as the corporate structure is concerned. The current chief executive officer (CEO) of Scientific Games is Barry Cottle.
