Top Slot Games by WMS

WMS Gaming Software Developer


WMS, short for Williams Interactive, is one of the oldest game studios in the business. It started operating in 1974 in Las Vegas and was mainly known as a pinball cabinet manufacturer in the beginning. As the company grew, it branched out and started developing numerous other types of games. Over time, WMS Gaming became one of the most recognizable names in the industry.

Since 2013, WMS Systems is part of Scientific Games. The acquisition led to the creation of numerous hit slots including Jackpot Part, Star Trek, Monopoly, The Wizard of Oz, Reel Em In, and many other popular slot titles. WMS is also behind major industry hits such as James Bond – Thunderball, James Bond – Casino Royale, James Bond – Diamonds and Forever, The Lord of the Rings Rule Them All, etc. As you can see, the famed developer has numerous branded slots in its library.

The WMS software isn’t focused on online slots only. Thanks to the Scientific Games merger, its library now includes many table games as well you can play for free or real money. WMS is not just big in the online gaming industry. Land-based casino fans can easily recognize the company’s cabinets such as Blade S32 built for premium content. With powerful casino game hardware under the hood and HD displays, these cabinets are the real deal.

The real steps forward were taken with the G+ and G++ series WMS slot game series. These slots came with a luxury seat and Bose speakers installed in the cabinets, creating a great 3D effect when you hit certain bonuses. WMS wants to provide its offline and online customers the best possible experience and it shows.

If you want a real quality experience, WMS casino slots are among your best choices.

Best WMS Slots – Most Popular WMS Slot Games In The US

WMS is behind some of the greatest slots in the legal US online casino industry. Ever heard of Montezuma and Montezuma Megaways? Or Spartacus Gladiator of Rome? Those and other hits such as Clint Eastwood, The Dukes of Hazzard, Top Gun, The Wizard of Oz, Bierhaus, and Men in Black among others have all been created by WMS hard-working team. The studio has released a bunch of branded slots that have no doubt played a major part in its popularity over the years.

WMS Gaming has revolutionized the industry with innovations such as Stacked, Expanding, and Chained Wilds for years. The Transmissive Reels tech is another one of WMS’ inventions that has taken video slot machines to a whole new level.

WMS Free Slots

If you want to try out all of the studio’s innovative special features you’ll try its slots for cash. However, you can also play WMS free slots if you’re a beginner or you’re just looking to have some fun.

As a matter of fact, playing slots for free before spending your bank roll is a very good idea. All of the online gaming sites with WMS software on our list allow you to play WMS slots online for free. Games such as Black Knight! Or Monsters & Mermaids offer top prizes for cash, but they are just as exciting when you play for free.

You may not win real coins, but virtual coins offer a similar level of satisfaction when you hit a big win. However for players coming from the UK, demo WMS slots are not available due to the recent UKGC restrictions.

Highest paying WMS real money slots

Most WMS slots have a RTP around the industry-standard 96% mark. Some older slots go below it, but there are some with a RTP as high as an amazing 99%! Hits such as Monopoly and Zeus are at 96% and 96.05% respectively. However, if you want the highest possible chances to win, you’ll go for Moon Shadow (98.10%) or Ooh Aah Dracula at 99%.

Although all WMS game types are truly exciting to play, your chances of hitting regular wins are much bigger with the higher RTP slots. Monopoly Big Event is our recommendation. Based on the popular board game, it offers excellent gameplay with a supercharged RTP of 99%.

WMS Mobile Slots And Apps


As one of the oldest companies in the business, WMS’ transition to online gaming has been a bit slow. However, the company evolved with times and adapted to the new reality in order to keep up with the competition. Not offering mobile-optimized games is corporate stupidity in 2020 and thankfully, WMS has not made that mistake.

You can play all the games on Android and iOS smartphones and tablets with ease. They’re all developed on HTML5 and suitable for a variety of screen sizes. WMS’ old-school gambling approach translated to modern technology is pretty cool. Don’t take our word for it – visit any WMS online casino from your smartphone and give the slots a try.

All the classics such as Montezuma and Zeus are mobile-optimized. Even the highest RTP WMS slots such as Monopoly Big Event can be played straight from your phone. You don’t need to download and install apps for them all. Just visit our list of mobile casinos with WMS software on your phone and enjoy the games remembering to gamble responsibly at all times.

WMS Progressive Jackpot Slots

Over the years, WMS has dabbled into literally all types of slots. From 3-reel classics to slots with the Megaways engine, the company evolved side by side with the industry. Besides the classics and modern slots, WMS has developed a number of progressives in its rich history that still stand on top of top jackpot lists.

Some of the progressive jackpots WMS has developed over the years are Jackpot Party, Leprechaun Gold, the Royal and Reel’em In series, Life of Luxury series, Money to Burn, and more. The company’s progressives can be divided into separate sections. The ones we mentioned are true progressives, but there are also wide area progressive jackpots such as Bigger Bang, Big Event, Press Your Luck, the Wizard of Oz series, Top Gun, Monopoly Series, and many more.

The two most popular jackpots in the studio’s portfolio are the Jackpot Party and Monopoly Series. Jackpot Party is a real party that consists of several slots with prizes that go beyond your imagination.

Monopoly is even better. Some of the slots in these series such as Monopoly Big Event have a RTP of 99% which is awfully close to a full 100%. Thanks to the Big Bet game and in-game bonus features such as the wilds, you can win a pretty big jackpot in this game if you’re lucky. With a RTP of 99%, we guess that you’ll certainly enjoy the ride trying them out.

WMS Casino Bonuses In The US

Many of the WMS software casinos on our list offer brilliant bonuses and promos that could boost your bank roll from the start. From deposit and no deposit bonuses to various other promos, you can spend all that cash on most WMS slot games if the bonuses were specifically designed for them.

Of course, not all casino bonuses are specifically aimed at WMS slots. That’s why we urge you to check and double check the terms and conditions to learn what games you can spend the bonus on.

The T&Cs will also ‘spell out’ the wagering requirement and other important stuff you need to pay attention to. These include minimum bets, games that qualify for the bonus funds, and the period you’ll need to complete the wagering in.

WMS Casinos No Deposit Bonus

A no deposit casino bonus is probably the best type of bonus you can earn in WMS online casinos. As the term obviously suggests, it’s a bonus you get for literally nothing (without a deposit). This type of bonus is pretty rare, but you can find them on the top gaming sites on our list.

In many cases, you can use these bonus funds on WMS slots. However, we strongly recommend checking out the T&Cs before you claim them. They will indicate the slots you can use the bonuses on, the wagering requirements, minimum bets, and other conditions you must meet to convert the bonus to cash.

Failure to do so will result in the casino forfeiting your bonus funds. Since no one wants that, read the fine print, understand the wagering req and specifics, before you click on the Claim button.

WMS Casino Free Spins

Among all the online casino game bonuses and online gambling promos you can earn in WMS casinos, free spins stand out as the best. This is not your typical bonus – instead of funds, you’ll be getting slot games spins for free on particular or all slots in a casino.

That’s not all the free spins you’ll be getting. Most WMS slots games come packed with free spins a player can earn by getting certain symbols on paylines across the reels. Some of the most notable examples are Top Gun and Raging Rhino. You’ll certainly win dozens of free games in these slots via the bonus features. When you add to that amount the free spins you get as part of the welcome package, that’s a lot of spins you get for free on desktop, tablet or a mobile casino.

You can use the free spins from welcome offers to try out new WMS slots. Or play your faves with them – whatever you do you won’t go far wrong.

WMS Software Alternatives For Slot Games

WMS’ slot games stand as among the most popular in the industry. They’ve caught up with the times, offer a seamless experience across all devices, and some of them come with RTP as high as 99%.

Still, some players will be looking for another challenge and luckily, the industry has a lot to offer. Games from juggernauts such as Playtech, Microgaming, Yggdrasil Gaming, and NetEnt all deserve a try no matter if you’re into WMS or not.

If you love playing slots that look and feel like video games, Yggdrasil’s games are a no-brainer. The Maltese developer was founded in 2013 and has done a great job of modernizing the slot industry overall. Its slots are true modern masterpieces with amazing graphics and a bunch of special features that can lead to sky-high jackpots for the lucky people out there.

NetEnt is another excellent provider that has dominated the industry for over a decade. Creator of mega popular slots such as Starburst and Gonzo’s Quest, NetEnt is one of the most exciting developers out there. Its portfolio is ever-expanding with a variety of games besides slots and casino games, making NetEnt one of the true iGaming powerhouses.

Along with NetEnt, Microgaming is considered the undisputed ruler in the industry. With hundreds of excellent slots and casino games, Microgaming has been dominating the online gaming landscape for a long time. The studio isn’t planning to hand over the reins soon with new releases that are bigger and better than their predecessors.

There you have it. If for some reason WMS’ slots simply don’t do it for you, you can switch to other alternatives and have a virtual blast.

WMS Awards

WMS has won a lot of awards during its history. Some of the trophies have been handed to it by leading industry organizations which speaks volumes of WMS’ reputation.

Some of the biggest awards the studio has received are four ‘Most Innovative Gaming Technology Product Awards’ trophies from 2008. The free online WMS slots that won these awards are Reel’Em In! Compete to Win!; Powerball Power Seat; Bluebird 2, and Ultra Hit Progressive.

The company is always striving to improve its products and portfolio. New WMS titles are adding exciting and high-paying features that will keep players interested in the studio’s games. We’re sure that new WMS hits are arriving soon and have no doubt that they’ll win more than a few awards.

WMS Reputation Gaming Licences, And Safety


As mentioned, WMS is one of the oldest companies in the industry and as such, it enjoys an excellent reputation. The company has licenses from the biggest governing bodies in the industry which ensure that it’s a reputable provider.

You don’t have to doubt the safety of its games as well. They are regularly tested for fairness by leading testing agencies. Even the free WMS casino games offer random results and you can expect the same if you play for cash.

This, however, doesn’t matter if you pick an unreliable on unregulated casino. To avoid making that mistake, choose a WMS casino from our list of top sites that use the studio’s software. You’ll be joining a properly licensed casino that offers gaming in a safe and secure environment.
