About WMS Gaming
Most slot studios have a history measured in years. WMS Gaming has one measured in decades, and before that, in pinball machines.
The company that eventually became WMS traces its roots all the way back to 1943, when Harry Williams founded the Williams Manufacturing Company in Chicago. For the best part of half a century, Williams was one of the defining names in pinball, producing legendary machines and dominating arcades. When that world began to fade, Williams did something most companies in decline fail to do: it pivoted, successfully, and built an entirely new empire in a different industry.
The Williams Gaming division was created in 1991, entering the slot machine market in 1994 and striking gold almost immediately. Their 1996 release Reel ’em In changed the conversation around what a slot could be, introducing multi-line, multi-coin secondary bonus payouts at a time when the rest of the industry was still thinking in single lines and fruit symbols. From that moment, WMS became a genuine force on independent casino floors across America and beyond. Jackpot Party, Zeus, Bier Haus, Spartacus and the Wizard of Oz series followed, each one cementing the studio’s reputation for delivering games with real personality and floor presence.
What made WMS stand apart from most of its contemporaries was where their creative instincts came from. This was a team built on video games and arcade culture, not casino tradition, and it showed. They brought the energy of interactive entertainment into slot design, pioneering the use of licensed intellectual properties in ways that had never been done before. Men in Black, Top Gun, Star Trek, The Lord of the Rings, Monopoly and The Price is Right all became WMS slot experiences, creating games that appealed far beyond the traditional casino audience. The Colossal Reels format, which stacked an enormous reel set alongside a standard grid, was another WMS invention that competitors rushed to imitate.
In 2013, Scientific Games acquired WMS for $1.5 billion, and following a further corporate restructure, the brand now sits under the Light and Wonder umbrella. The WMS catalogue remains available online and continues to attract players who grew up on these games in land-based casinos, as well as a new generation discovering them for the first time.
RTPs across the portfolio vary by title, volatility ranges from low through to high, and the sheer breadth of the library means there is something here for virtually every type of player. With decades of innovation behind every release, WMS is one of those rare studios whose back catalogue is as worth exploring as anything releasing today.
“WMS are a proper institution. The Zeus games, the Wizard of Oz series, Bier Haus on the casino floor, these are titles that shaped what people think a slot should feel like. A genuinely important studio in the history of the industry and the games still hold up brilliantly.” Mark, Content Editor
“Grew up seeing WMS machines in casinos and they always stood out. Playing them online now still brings that same energy. The catalogue is huge and there are some absolute classics in there. Definitely worth digging into if you haven’t already.” Jamie R, Streamer
