WMS Gaming

WMS Industries, established in the 1940s, initially founded WMS Gaming. Before the company became part of casino games, it created arcade games, specializing in pinball games.

WMS Gaming, as we know it, was founded in 1974 and started as Williams Manufacturing Company. It’s gone through many changes since becoming Williams Interactive, and SG Gaming purchased it in 2013. It became part of the SG gaming profile, delivering quality games with excellent bonus features.

Nowadays, WMS is integrated with Scientific Gaming Digital, which recently rebranded to Light and Wonder. As WMS, the brand first released a slot machine in 1996 named Reel ’Em In and has since continued to expand its portfolio. This company started offering online slots later than other providers, but most of their online slots are now available on mobile and use HTML5.

Its game library has multiple titles, offering over 100 titles, ranging from video slots to roulette. WMS Gaming produces some creative branded casino slots and has won gaming awards before. WMS titles also use RNG and offer fair and reliable gameplay.

What Makes WMS Online Casinos Stand Out?

WMS is one of the oldest names in the iGaming industry, right up there with Microgaming and NetEnt. While it might not have jumped on the iGaming bandwagon as fast as the other two, it still offers quality titles. WMS stands out thanks to its years of experience in the entertainment industry, ensuring it delivers quality games.

Its focus is on satisfying players, and WMS games reflect that focus. You’ll find many popular bonus features, like bonus wheels, in its slots. There are also various pop culture references found in the slot themes. Large progressive and local jackpots, high RTPs, and intriguing game mechanics are often seen in the titles.

While its parent company, Light and Wonder, is legal and licensed in 29 jurisdictions, WMS isn’t left behind, holding UK Gambling Commission and Malta Gaming Authority licenses. This brand is known for providing quality and fair products to casinos.

Another aspect to keep in mind is that, as a subsidiary of Light and Wonder, WMS slots have access to the same network and services as Light and Wonder. This means that WMS casinos get titles using the latest technology and connections to Light and Wonder. Overall, WMS is a brand that offers quality and security, which boosts its popularity.

Popular WMS Gaming Casino Games

WMS slots are known for their creative and unique themes and innovative technology. The brand’s games were good before becoming an SG Digital subsidiary and only continued improving after the merger. You’ll find slots based on movies, classic titles, 3D slots, and more.

WMS offers over 100 slot titles, which make up the majority of its gaming library. WMS offers some table games, specialty games, and even video poker. However, this singular focus on slots resulted in popular slots like Zeus and Montezuma.

This company values the player experience, and the games it releases are always innovative, exciting and feature fun gameplay. You’ll often find bonus features providing multipliers and free spins. Another excellent aspect of their games is the branded titles they provide. These games range from Bruce Lee and Monopoly Grand Hotel, to Star Trek and Willy Wonka.

Most of the titles are based on slot machines by WMS, which they rebuilt for online play.

How We Rate Our Top Recommended Sites

We care about our readers and take your safety seriously. As such, we always provide the latest information and thoroughly research online casinos to recommend only the best platforms to you. Not all online casinos are safe and trustworthy, so we do an in-depth platform investigation and rate it according to our company guidelines.

The guidelines include testing the site and looking into the following services and features of the site:

Fast Withdrawals

Fast withdrawals mean the casino’s processing time and payout speeds need to be quick. Many new players don’t realize that the processing time adds to the payout time. We look for shorter processing times, ideally less than 24 hours, and standard payout speeds in a casino.

Mobile Friendly

All casino games must be mobile-friendly, as many players use their smartphones to access casinos. The world-class HTML5 used to design these games and platforms ensures the game and platform perfectly renders to fit your screen. We test the mobile interface and see how it compares to the desktop one.

Fair Bonuses

Don’t get fooled by a significant bonus amount. For a promotion to be fair, it needs to offer reasonable bonus terms. These terms include the wagering requirements, the minimum deposit, the winnings cap, the expiration period, and more. Players must be able to complete the bonus terms within the allotted time.

Game Offering

The game selection is vital, as that’s the reason you’re on the site. The casino can list hundreds to thousands of titles, but we check whether all the WMS games, from slots to table games, are available. Only then will we be satisfied with the game offering of the online casino.


If a casino neglects and mistreats its players, you can immediately see it in comments and reviews. While we test the platform ourselves, we also take into account the online casino’s existing reputation.
