WMS has played a decisive role in games and entertainment since Harry Williams founded his Chicago-based company in 1943. A Stanford engineering graduate who devised the “tilt” mechanism for pinball machines, Williams changed the nature of pinball in wartime America. He and his firm had an unsurpassed ability to devise new game features and stay in touch with the changing tastes of the amusement market. The company retained this inherent strength when it entered the home video market in the 1980’s and, eventually, casino-style gaming in the early 1990’s.

We stand as one of the world’s leading slot suppliers with an unmatched reputation for innovative game design and development. Our portfolio includes many of the industry’s most popular and profitable branded casino slots and state-of-the-art gaming technologies.
