About WMS

WMS was founded by Harry Williams in 1943 (nearly 70 years ago) as he invented the ‘tilt’ device for the much played pinball machine. WMS then applied this innovative approach and began making video games in the 1980s and 1990s. Subsequently, WMS focused on the casino gaming industry in the early 1990s (1994 to be precise) and started producing slot machines.

Since 1994, WMS has since become one of the leading suppliers of innovative casino gaming devices worldwide. They created some of the most popular games of all time including proprietary titles such as Reel ‘em In and Jackpot Party with licensed titles such as Monopoly, The Wizard of Oz, Top Gun and Star Trek.

The culture is to be innovative and focus on their players – they have introduced 4 revolutionary technology platforms which as Community Gaming, Sensory Immersion Gaming, Transmissive Reels Gaming and Adaptive Gaming. The company has been listed on the New York Stock Exchange since 1982 too which shows their transparency too.

As a result, they have won much deserved recognition and awards such as the Best Slot Product, inclusion in ‘America’s 100 Best Small Companies’ in 2010 by Forbes, inclusion on Information Week’s list of the 500 most innovative business technology organizations, a spot on Casino Journal’s Top 20 Most Innovative Gaming Technology Products and the ‘Favourite Bonus Round’ in Casino Player Magazine amongst others.

As you can see, they have a huge wealth of experience and expertise that they have now applied to their first online casino venture, Jackpot Party Casino. Launched in late 2010, they bring all WMS’s unique games to the online world for the very first time. The casino is also licensed in Alderney which is the strictest jurisdiction around. Their aim is provide you with the ‘most exclusive and authentic online gaming experience’ possible though.

Despite WMS’s success in the United States of America (especially in Las Vegas), Jackpot Party is only open to UK customers at the moment due to legislative issues. Once online gambling in the US is legal, their casino will fly. The casino software itself offers all types of casino games but their main selling point is their slots. They can only be played in your browser though (no download needed).


Here at CasinoManual.co.uk, we are in love with their video slots. As mentioned above, they offer land based classics such as Zeus and Wizard of Oz. The Zeus slot can reward you with up to 100 free spins with an unlimited retrigger feature and the Wizard of Oz slot has lots of bonus features, footage from the iconic film and free spins.

You can also play their sequels (Kronos and Wizard of Oz Ruby Slippers) which are just as good. They do offer many good games but I really like Black Knight. It’s all about the free spins feature where you get 7 free spins. What makes it great is that you can get up to 3 sticky wild reels during the feature. If you get them early on, you could be in line for a huge payout!
