Williams Gaming might not be a software developer that will be hitting the headlines too often these days. The company’s approach is simple – they let their work speak for themselves. Therefore, it comes as no surprise to see the list of online casino sites working with WMS grow regularly.

Williams Gaming has released over 130 titles for online market, simultaneously supplying land-based casinos with gaming machines. Some of the hottest cabinets available in brick and mortar WMS casinos are James Bond Thunderball, James Bond Casino Royale, The Lord of the Rings Rule Them All… The online gambling community is better acquainted with Williams Gaming slots, designed or adapted for browser and mobile play – Raging Rhino, Amazon Queen, Frozen Inferno, Bruce Lee… The average payout value of WMS slots is around 96% while fantasy, mythology, Orient, fairy tales, Sci-fi, and ancient civilizations are the most commonly exploited themes.
WMS is particularly well-versed in branded slots. Thanks to a licensing agreement with Hasbro, they have created numerous games based on the Monopoly board game. They have also launched a range of slots based on The Wizard of Oz films, and themed slots on the rock band Kiss, the movie Anchor Man, the performer Elvis in Elvis: The King Lives, the Star Trek franchise and the martial arts icon Bruce Lee.
No table games, just slots, slots, slots. WMS is known in the world of casinos for manufacturing innovative and engaging cabinets and their extensive experience shows in the online slot universe, too. We can only assume that if they wanted to develop table games for web-based casinos, they would have done it by now. So, no virtual roulette, poker or blackjack, but still one of the most well-versed slot developers out there.
Progressives are not the primary focus for WMS developers, but the company has some options on offer if you care to spin the reels of a machine that is connected to a progressive jackpot pool. WMS first started experimenting with networked games back in the 90s, so it’s not surprising that the company is now using that formerly acquired experience in the digital gaming arena. In 2016, WMS released its first progressive jackpot online slot, called Dancing in Rio. It has 5 reel and 40 paylines and a Rio de Janeiro carnival theme.
Casino games and live dealer titles are not a part of WMS arsenal and, for the time being, there are no indications that the company will break into this part of the online gambling market. For too long, they have been contributing to the development of slot machines and everyone knows WMS to be synonimous with slots, so going into live casino would just seem like a strange move for them.
Let’s not forget to mention that WMS games are all available for iOS and Android. In their core, they remain the same; the only difference is the shrinkage of the interface for a smaller screen. All features from the desktop versions are present, with some slight changes to the user interface, to make the game easier to play on a smartphone or tablet.
With the few exceptions here and there, the following bonus features are typically found in games signed by WMS:
The company Williams Gaming has a rich history and quite a lot of priceless experience in the development of both land-based and online slot machines. This is a reputable and reliable company that has partnered with various leading casinos worldwide which means that video slot machines from WMS can be found in an abundance of online casino sites. Similarly to IGT, WMS first swarmed the casino floors of Vegas with their cabinets. Now you can enjoy their timeless slots from the comfort of your home.
