⭐ What makes these the best WMS slots to play in 2022?

The 10 titles included in the list best represent the ability of WMS Interactive to produce industry-leading games. These are premium casino games that feature a high RTP, exciting bonus rounds, and all the features that best showcase why WMS is considered to be one to the top slot game developers in the world.


⭐ Who are these games for?

Like most WMS products, these slot machines speak to the heart of 'traditional' slot fans, bringing to the screen the same top-quality entertainment gamblers grew to love at land-based casinos in Las Vegas and Atlantic City.


Amazon Queen

Amazon Queen slot

Amazon Queen has the standard 5-reel layout and it comes with a total of 20 fixed paylines. This WMS slot game features up to 100 free spins bonus rounds, however, you won't see any multipliers.

The highest payout can go as high as $45,000 and you can achieve it by wagering the maximum of $60 per spin. The minimum bet, on the other hand, is set at $0.01, which means anyone can play the game.

Even though the slot's RTP is a bit below the average, the high volatility game makes the gameplay rather thrilling. Besides, who wouldn't want to try this high-resolution lively gem setup in the Amazon jungle?


Crime Pays

Crime Pays Slot

Crime Pays is one of the highest RTP WMS slots. It features 5-reels and 50-paylines that players can adjust.

You can bet as low as $0.5, and as high as $60 per spin. And with the medium-volatility-high-RTP combo, this video slot machine pays out wins more often than most.

You can land on 4 different scatters, trigger a 2x multiplier, or get lucky with the wild symbols. And if it's your lucky day and you manage to trigger a bonus round - the 30x multipliers will be activated.


Dancing in Rio

Dancing in Rio's RTP may look low at first glance, but when you see the maximum jackpot - you'll change your mind. With a maximum bet of $50 per spin and a little bit of luck, you can become heavier for $250,000.

Event-themed WMS slot machines are not a rarity, but the 5-reel and 40-payline grid is something we don't see often. And WMS Gaming has created a slot that is just as fun as the Rio Carnival.

This online casino game features 5 jackpots - Mini, Minor, Major, Burst, and Pulse. The Pulse brings a multiplier of 500 times!


Wizard of Oz: Ruby Slippers

Wizard of Oz: Ruby Slippers Slot

Wizard of Oz: Ruby Slippers brings to you another jackpot party with a win as high as $250,000. The even better news is the RTP which is almost at 96%, which is the industry standard.

Apart from being one of the most popular WMS slot games of all time, it is among the few slots that are based on TV shows.

You get a chance at the maximum win when you land on all scatters, which will multiply your winnings by 500x. And then there are the magic bonus boxes, where you'll be looking for the Witch's broom. Even if you don't find it - you'll be greeted by some amazing prizes.


Enchanted Kingdom

Enchanted Kingdom

What more could you ask of online slots than a $765,000 jackpot? Like many other free WMS slots, Enchanted Kingdom works with a medium volatility model and a slightly below-average RTP percentage.

Younger players may have never stepped into land-based casinos, but WMS Industries brings the best to their mobile devices. The Enchanted Kingdom slot features a win of 9,000x your wager and it follows a fairytale story.

Even though these aren't mechanical reels, they provide you with a couple of bonus features, and you can place bets ranging from $0.30 to $150.


KISS Shout It Out Loud

Kiss Shout It Out Loud!

If you love KISS, have a thing for slots, and are looking for a fun game - KISS Shout It Out Loud might be the perfect pick for you.

This WMS rock-themed slot comes with an RTP of 95.90%. The 5-reel, 4-row, 100-payline layout lets you play with up to $40 per spin.

Unlike other software providers, most WMS games don't lack bonus features - and KISS is not an exception. You will have the chance to pick between 3 different bonuses once you unlock the slot's bonus round.


Monopoly Mega Movers

Monopoly Mega Movers

We're sure you've played the Monopoly board game, but have you ever tried Monopoly Mega Movers? Deciding to give this game a go will not only give you access to the base game, but it will unlock the world of three more wheels.

These wheels give out various bonuses, such as an upgrade, free spins, and jackpots. Apart from the extra wheels, you get wilds, free spins bonus rounds, and Monopoly Mega Movers jackpots.

Giants Gold

Giants Gold Slot

Giants Gold is among the rare WMS slots that work under a low volatility model. This magic-themed slot has an average RTP of 96.21% and it can get you a maximum cashout of $100,000.

However, the low volatility is not the only thing that sets this online casino game apart from the others. In fact, Giants Gold features 2 separate slot machines. One is a 4-reel 5-row grid, while the other is a 12-reel 5-row grid that has up to 100 paylines.

Expanding wilds, free spins, multipliers, and a wild symbol is what you get if you decide to start playing Giants Gold.


Spartacus Gladiator of Rome

Spartacus Gladiator of Rome Slot

If you're up for playing with 100 bet ways, this WMS Gaming slot is the right choice for you. Apart from the stunning graphics, this 5-reel 5-row grid features transfer from the base game to the Colossal Reels, and a variety of other bonus gameplay specials.

US players can place bets ranging from $0.01 up to $5 per 2 lines. The maximum win may not seem much compared to the rest of the WMS slots, but the game-play is as thrilling as it can get.

The maximum multiplier that this slot machine has is 20x, and when you land on 5 Colosseums, you get 20 free spins too.


Cool Jewels

Cool Jewels Slot

We saved the best for last - Cool Jewels is a WMS slot like no other! This is a truly unique slot game, as it has no paylines.

Cool Jewels has a 6x6 layout and instead of fixed paylines, you can see meters that show you the number of free spins you have, as well as the paytable.

Cascading reels, exploding wilds, and 10 free spins are only some bonus features available at this cool slot. Bet as low as $0.50 or as high as $200 and aim for the highest win of $250,000!
