WMS has a long history in gaming that started in 1943 under the name of Williams Manufacturing Company. It was a popular producer of pinball machines, but as the arcade industry declined in the 1990s, the company started looking into other markets. It created WMS Gaming in 1991, which released its first slot machine in 2006, called Reel 'em In.

WMS Gaming quickly expanded its offering and became a leading slot developer. In 2010, WMS started offering its best games online. In 2013, the company was acquired fully by Scientific Games Corporation and is now a wholly-owned subsidiary.
