About WMS
WMS, founded originally as Williams Manufacturing Company, back in the 1940s, began its journey in the entertainment world by developing pinball machines. They saw rapid success, and quickly became one of the leading names in the industry – and before long, they transitioned into producing video lottery terminals and slot machines.
Over the years, WMS became a subsidiary of Scientific Games – alongside other providers like Barcrest. They are now part of the Light & Wonder group – a rebrand of SG, essentially. WMS slots are fully regulated and licensed by the UK Gambling Commission, and this ensures you’re guaranteed fairness whenever you play them.
Today, the extensive list of WMS slot machines ensures you can enjoy free WMS slots at many online casinos. The slots WMS produces are often packed with exciting bonus features, and while many are offline-only, their online offering continues to grow exponentially.

Another game worth checking out is KISS, of course, inspired by the legendary rock band of the same name. Offering five reels and a massive 100 paylines, the game boasts an RTP of 95.94% alongside a unique “dual reel” setup.

Montezuma
Montezuma, one of the top WMS Gaming slots, is a 5-reel, 30-payline game that’s set in an ancient Aztec civilisation. The game offers a superb free spins round where wins are multiplied by up to 10x, and it’s also possible to re-trigger them an indefinite number of times, scooping up to 25 new free spins each time you do.
Raging Rhino
Raging Rhino is one of the most volatile WMS free online slots, and it’s designed around a 6-reel, 4-row setup. You’ll find 4,096 ways to win, and it takes you on an African safari adventure. It’s famous for its free spins round where multiplying wilds come into play.
Bruce Lee
Inspired by the legendary martial artist of the same name, Bruce Lee is a 5-reel, 60-payline slot with an RTP of 96.05%. The game offers a unique mixture of free spins, wilds, and scatter symbols. There are three different bonus rounds – including an elusive super free spins.
Ruby Red Slippers
WMS casino slots like Ruby Red Slippers are world-renowned, and this title is available at both online and offline casinos. Based, of course, around the magical world of The Wizard of Oz, the game has five reels and boasts 30 paylines. There are multiple bonus rounds, including Emerald City free spins.
Amazon Queen
Amazon Queen is a jungle-themed slot with five reels and 20 paylines, offering an RTP of 95.94%. While there isn’t too much happening within the base game, landing three or more Amazon Queen symbols awards up to 100 free spins – and here, the wild symbols expand, and can land on all five reels.
Frozen Inferno
While not perhaps one of the best-known WMS Gaming slot machines, Frozen Inferno is a unique title worth playing, if you get the chance. It offers a unique five-reel, 40-payline setup, and boasts an above-average RTP of 96.36%. You get to choose between two game modes: Frozen Wilds, in Frozen, or Expanding Wilds, in Inferno.
88 Fortunes Megaways
88 Fortunes Megaways is a relatively new slot from WMS, and this is based, of course, on the original 88 Fortunes – one of the most successful slots released to the Asian market. This version features Big Time Gaming’s Megaways mechanic, and the game boasts cascading reels, free spins, and even a localised jackpot feature!
Black Knight 2
Black Knight 2 is a sequel to the popular WMS slot Black Knight, featuring a mediaeval theme with 5 reels and 40 paylines. The core of the game is its unique bonus, triggered by landing three or more scatter symbols. During these free spins, the Black Knight acts as an expanding wild. When they land, they lock in place for the remainder of the spins.
KISS: Shout It Out Loud!
KISS: Shout It Out Loud is a rock-themed slot based on the legendary band KISS. If you play WMS slots, there’s a good chance you’ll have already seen this title, as it’s one of their most popular – and the action unfolds on a unique dual-play arena, with a combined 100 paylines active.
The Wizard of Oz
Finally, there’s the Wizard of Oz – one of WMS’s most iconic slots, based on the classic 1939 film. This five-reel, 30-payline game takes you on a magical journey to Emerald City, and, if you’re lucky, you’ll encounter the game’s bonus features like Glinda the Good Witch’s random wilds, the Wicked Witch Free Spins, and the Road to Emerald City bonus round.

| Pros of WMS Mobile Slots | Cons of WMS Mobile Slots |
|---|---|
| Convenience - you can play WMS slots free anywhere, anytime. | Data Usage - some of WMS’ slots are quite graphic-heavy, which can consume a lot of your mobile data. |
| Compatibility - today, most WMS slot titles work on most mobile devices | Limited Titles - not all WMS slots are currently mobile-optimised at the time of writing. |
| Fairness - WMS’ mobile slots are certified by organisations like eCOGRA, too. | Screen Size - WMS’ mobile slots aren’t as “good” as those from, say, NetEnt - which means not all titles automatically adjust to fit your screen size. |
