WILLIAMS GAMING REVIEW

Williams Gaming, or WMS, is the kind of gaming manufacturer that new companies are hoping to become. Almost as old as the legal forms of gambling, WMS Gaming was founded in 1943, under the name Williams Manufacturing Company.

Play WMS Slots at Online Casinos

In 1991, a new division was launched and shortly after, Williams Gaming released the first video lottery terminal, followed by the slot cabinet Reel’em In, which became an instant hit.

The 90s were marked by a series of highly successful products: Jackpot Party, Filthy Rich, Boom… Williams Gaming grew together with the legalization of gaming across the state, becoming a corporation in 1999 and focusing on large-scale gaming cabinets manufacturing, distribution, leasing, etc.

2013 has brought significant changes in the company’s structure and business model – WMS parent company (WMS Industries) became a part of Scientific Games, the owner of Bally Technologies. Currently running 4 divisions (lottery, digital, social, and gaming) SG continued to expand and build the gaming imperia, founded on the trust, legacy, and reputation of one of the gaming industry pioneers – WMS. In 2016, SG recorded a somewhat unexpected revenue increase and some of the profit was invested in acquiring Red7, a renowned casino games and sports apps developer.

LIST OF BEST WILLIAMS GAMING ONLINE CASINOS

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.

LIST OF TOP WILLIAMS GAMING SLOTS

You will find over a hundred slots titles in the WMS online portfolio and the selection includes many different themes and subjects. Many of their slots will be familiar to those who have had the chance to play in land-based casinos.

Games such as Raging Rhino, Montezuma, Gold Fish and several others were expertly adapted for instant online play. Williams Interactive slots often boast bold, vivid colours and crisp detailed graphics, delivering a range of exciting in-game features.

WILLIAMS GAMING SLOTS RTP

All of us, as casino players, always demand fair odds. We’re also savvy enough to opt for games with the highest possible RTP percentage rates. From the perspective of slots, RTPs can have a wide range of values. The RTP of WMS online slots oscillates from around 94% up to above 98%, offering a fair deal to players who know what they are getting into.

The highest returns come with slots like Ooh Aah Dracula with 99% RTP, Moon Shadow with a 98.10% RTP, Wild Knights: King’s Ransom with 98% RTP, whereas most games have percentages around 96%. Monopoly Once Around Deluxe has the lowest return at 94%, while Monopoly Roulette Hot Properties is a bit higher with an RTP of 95.47%.

Rome & Egypt Slot 96.00% 88

WHAT CASINO GAMES DO THEY PROVIDE?

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.

WILLIAMS GAMING FEATURED GAMES

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.

Williams Gaming featured games

WILLIAMS GAMING TABLE GAMES

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.

PROGRESSIVE JACKPOT GAMES FROM WILLIAMS GAMING

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.

WILLIAMS GAMING LIVE DEALER GAMES

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.

WHAT ELSE?

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:

  • Bonus Game (picking games)
  • Bonus Wheel
  • Free Spins
  • Multiplier
  • Jackpot
Red Tiger Gaming History
