WMS currently stands in an exciting position in the iGaming industry. The software provider is both a traditional old-school provider and one looking for a bright future of innovation. This page will help you become familiar with WMS and understand this fascinating contrast. After reading the following guide, you will know the best WMS slots to play and the top online casinos where you can play them.

Before we delve further in, we first must look to the past. It all started in 1994 when WMS debuted as a developer of slot cabinets for brick-and-mortar casinos. After several hugely successful games and an online gambling revolution, the company brought its land-based hits to online casinos. Since then, WMS has released a steady stream of virtual versions of its classics while embracing modern video slots.

In 2013, WMS merged with Light & Wonder (previously Scientific Games) to become a wholly-owned subsidiary. Since the merger, WMS has continued to deliver top-notch slots to players worldwide.

About WMS Gaming

In the world of online casino slots, there are experienced software developers, and then there's WMS Gaming. The brainchild of Harry E Williams and born out of the Williams Manufacturing Company, Williams Electronics Inc first came on the gaming scene in 1974. In the days of mullets, mustaches, and mistakes in the fashion department, WMS had a different look than it does today. Indeed, the first games it produced were coin-operated arcade games and pinball machines.

Despite several changes in its status as a business (it went from independent to owned by Seeburg and then independent again), "leisure" games remained the company's forte. By 1987 it was all changed when the company rebranded itself as WMS Industries Inc, a name later shortened to WMS. A year later, it acquired rivals games company Bally/Midway, and that's when its move into casino gaming started.

By 1994, WMS had started developing its casino software, and in 1996, it released its first video slot, Reel'em In. Offering multiple win lines, adjustable betting, and a bonus game, this was one of the first examples of a "modern" video slot and helped set a marker for the iGaming industry in years to come. After offloading Ballys/Midway and its video gaming department in 1998, WMS closed its pinball division in 1999 to focus all of its attention on slot machines.

As well as expansion in the US, WMS started to make a name for itself across the Atlantic. The company's Monopoly-themed slot machines became popular in pubs and clubs, and, from 2001 onwards, it found a niche in the live gaming world with its movie slots. By 2010, WMS had not only shown that video slots could be networked across live casinos to create mega jackpots, but it had also started offering online gaming to players worldwide.

This was followed by a move into the mobile slot games market in 2012 and the launch of a Facebook slot game, Lucky Cruise. Eventually, by 2013, WMS was purchased by Scientific Games, and today, it forms part of an industry-leading slots and casino games developer. Under the guidance of Light & Wonder (previously Scientific Games), you can now find WMS-powered slots across many of the best real money slot sites and social media networks such as Facebook.

WMS Slots

As a company launched in the land-based slot machine industry, WMS has stuck to its roots even following the transition to an online slot provider. The company has full virtual game versions of its land-based classics. However, as the modern age of video slots has evolved, WMS slots have become more complex, especially following its acquisition by Light & Wonder (previously Scientific Games). 

The WMS gaming portfolio has a nice balance of basic games (three reels) and high-concept slots. There are around 150 WMS games, making selecting the absolute best WMS slots challenging. We recommend playing a collection of WMS games in demo mode to see which titles suit your budget, betting styles, and gameplay preference. 

In the meantime, below are some of the best WMS casino games we think are worth checking out:

Raging Rhino – RTP: 95.91%

Avoid a stampede and complete your safari among Africa’s wildest animals to take home the jackpot on Raging Rhino. A relatively straightforward game, this slot is primary but still looks great with its African savannah backdrop. Gameplay is over 6 reels with up to 4,096 ways to win while betting limits welcome beginners and high rollers alike. We love the free spins round, where you can gain up to 100 free spins with 2x or 3x multipliers. 

Zeus – RTP: 95.97%

With its Las Vegas slot vibes and stylish design, Zeus from WMS feels like a bridge between old-school slots and modern video slots. Since 2013, this has been one of the best and most popular games in the WMS portfolio. It includes 5 reels and 30 paylines and uses Greek mythology to create an exciting game. Zeus also features an up to 100 free spins mechanic, while wild symbols can cover entire reels during the free spins bonus. 

Spartacus Calls to Arms – RTP: 96.05%

Launched in 2017, Spartacus Call to Arms is a modern slot with five reels and 50 paylines. With its ancient battle theme, it is an all-action game featuring a main reel set and two rows above. When you get a wild on top, it moves to a random position on the central reels. Spartacus Call to Arms also boasts a free spins bonus, where 20 free spins are available with multipliers of 1,000x.

Over the years, WMS has been a prolific creator of online slots. That production has increased since the company merged with Light & Wonder. You can now expect a bunch of new WMS slots launched each year. Below are the latest games from the provider that have arrived in 2024 or the year before:

  • Kronos Megaways
  • Direct Hit Featuring Money Zone
  • Invaders Megaways
  • Spartacus Super Colossal Reels
  • Cluedo Cash Mystery

Types of WMS Slots

Regarding slot types, WMS has always had a penchant for themed games. These spinners fall squarely into the "video slots" category and offer the perfect combination of entertainment, interaction, and potential payouts. Indeed, because WMS started life as an arcade game developer, it knows how to make something "fun," and that's what you'll find when you play its latest slots. Everything from the Raging Rhino slot and the Bruce Lee: Fire of the Dragon slot to the aforementioned Monopoly can be found when you scroll through the lobbies of any WMS partner site. However, it's not all about video slots.

Although 3D slots aren't a significant part of the WMS menu, you will find classic slots with all the traditional bells and whistles (i.e., fruits, in this instance). Moreover, you'll also find a growing selection of WMS progressive jackpot slots when you spin around the internet's best sites. Given that WMS started experimenting with networked games in the nineties, it's little wonder that it's now using that experience in the virtual arena. In 2016, WMS released its first progressive jackpots online, the Dancing in Rio slot, and it's now looking to create even more as we move through 2024 and beyond.

New WMS Slots

As you'd expect from a developer pumping out games for over 40 years, WMS constantly adds new slots to its collection. This is great news for slot players because it means you can join one of our partner sites and gain instant access to the newest WMS slots in an instant.

WMS Progressive Jackpot Games

WMS Gaming has a unique history with progressive jackpot slots. These games have a jackpot that grows over all versions of the game across all casinos and bets. However, WMS has taken a different approach. 

Firstly, in 2011 the company launched Jackpot Party, a bespoke online casino that has since come under the ownership of WMS parent Light & Wonder. Jackpot Party is unique because it collects land-based Las Vegas slots and allows gamblers to play them online. These virtual versions of traditional slot machines have a five-level progressive jackpot pool that randomly drops: Jackpot Party Mega, Super, Blowout, Surprise, and Confetti.

For its online slots, WMS developed a feature known as Sitewide Progressive. This is essentially a local progressive jackpot that accumulates only in the casino and not across all casinos where a game is present. Therefore, this means jackpots are lower than network progressives but still higher than a regular fixed jackpot. 

It is also worth noting that Sitewide Progressive is attached to any WMS slot the online casino stocks. In other words, all WMS video games in a casino that supports “Sitewide” will be progressive.

WMS Mobile Casinos

Gambling on your mobile device is much more convenient and allows you to access WMS slots wherever and whenever you want. What’s not to like about carrying an online casino in your pocket?

Our WMS casino review team looks explicitly for mobile-friendly leading casino operators. All casino sites support mobile these days, but we select the casinos that truly make the mobile experience memorable. 

Perhaps the easiest way to enjoy one of our recommended casinos is through your mobile web browser. Simply head to the casino, sign in, and start playing. Modern casino sites are built on HTML5 technology to ensure the website runs as smoothly on mobile as on desktop. 

If the casino you pick provides a dedicated casino app for iOS and Android, we recommend installing it. An application has several benefits over a mobile browser site, including better performance and less load on your battery. Furthermore, an app will send you notifications about the latest bonuses and games while providing a UI designed specifically for mobile devices.

WMS Casino Bonuses and Free Spins

You don’t need to look far to find lucrative WMS promotions. Many online casinos have free spins for online slot players. These promos are handy because they give you extra spins on a slot game chosen by the casino operator. Sometimes, the casino you choose will select a classic or new WMS slot for its free spins promotion. 

Other WMS casino offers players can enjoy include deposit matches and no deposit bonuses. Of course, you can also claim a welcome bonus when you register with one of the WMS casino sites we list on this page. Welcome packages are a fantastic way to boost your bankroll as you start playing.

However, please always read the terms and conditions of any casino bonus you'd like to claim. Here at, you can always find the best online casino bonuses and the standard bonus offers that are always offered to new players. Operators have specific limitations, such as which payment methods you can use and what games contribute towards the offer. Promotions also come with a wagering requirement; the number of times you must wager the bonus amount before cashing out related winnings.

WMS Gaming vs Other Game Providers

There is no shortage of well-known online slot providers out there. Each offers its selection of games with different themes, designs, features, and volatility. When you visit the WMS gaming sites we recommend on this page, you can also play games from a wide selection of providers. Yet, choosing the best of the best is challenging. That’s why we’ve listed our top-rated software companies that have a worldwide reputation and availability:


Microgaming is the oldest and biggest iGaming software provider. A trailblazer in game fairness testing and industry regulation, Microgaming works with many subsidiaries and now has a portfolio totaling over 500 slot games.


There are so many benefits with NetEnt; the company’s slots are available at most online casinos, and games are known for innovative features and fantastic visuals, while the company also has hundreds of games, some of them the most popular online slots ever made.


From the casino floors of Las Vegas to the online casinos worldwide, IGT is a developer that has conquered the land-based and online industries. Some of the most recognizable slots come from this developer, creating noteworthy games since 1990.


An all-around online casino giant that also provides software for casino sites, Playtech slots are popular. Over the years, the company has become known for its games based on movies, but it also has plenty of excellent original slots. Playtech is also known for having a wide selection of progressive jackpot games.

Pragmatic Play

A much newer company than the others on the list, the growth of Pragmatic Play has sent the company into the big leagues. A prolific developer that rolls out multiple slots each year, Pragmatic Play is gaining a reputation for feature-rich games with striking graphics.

How We Rate and Review WMS

Never miss out on the best online casinos again. Our online review and rating system allows us to recommend only the leading casino operators. Plenty of care and attention goes into picking a casino site; we never choose one randomly. We conduct a painstaking multi-step review that leaves no stone unturned. 

Ultimately, we aim to provide the ultimate WMS casino slot experience, so we consider every aspect of an online casino. If a casino cannot meet our strict standards, we will not recommend it on this page. So, what exactly does our review process look like? Well, we cover the following criteria for every casino we visit:


The first sign of reputability is a license, so every WMS casino we recommend must have a license with the United Kingdom Gambling Commission (UKGC) or another legitimate gambling authority.


You should never worry about your personal information falling into the wrong hands. We check casinos have an ironclad privacy policy and use encryption technology to protect data.


WMS slots are independently tested to ensure they are fair, and we expect online casinos to go through the same process to prove their reputability.


Gamblers like as much choice as possible when depositing and withdrawing. We check for diverse payment options like debit/credit cards, e-wallets and prepaid cards. Moreover, we only select casino operators who partner with secure financial companies.

Game Selection

Alongside the best WMS gaming slots, the casino sites we recommend provide a wide selection of other slots, table games, and live casino offerings from a range of top providers.


At our online casinos, you can grab generous welcome bonuses, deposit matches, and free spins. We specifically look for casinos that have lucrative promos with fair requirements.


Whether it is an FAQ section or points of contact, such as live chat, we demand all casino operators take care of their customers. This is important if you need support when there is a problem.


Whether you gamble on a desktop or mobile device, the UI should be easy to use and look good. Sure, aesthetics are subjective, but our reviewers never compromise on functionality.

How Safe Are WMS Games?

Any company that's been around the gaming and casino industry since the 1970s and survived has to be doing something right. With reputation and trust worth their weight in gold, WMS couldn't afford to compromise on anything back in the day or now. Of course, a reputation for being safe, secure, and fair is all well and good, but today's online slot fans want some evidence. Fortunately, WMS and its parent company, Scientific Games, have just that. Under the guidance of Scientific Games, each WMS slot machine is checked, verified, and certified as fair by eCOGRA. Testing each game's random number generator (RNG), eCOGRA can assure customers that WMS offers safe real cash slots and that it's fully compliant with the regulation procedures set out by agencies such as the Malta Gaming Authority.

New Slots Calendar

New slot games are popping up more often than you think. Over the years we’ve built up relationships with the internet’s leading slot game developers, so if a new game is about to drop it’s likely we’ll hear about it first. If you don’t want to be behind the curve, stick with us.
