Like other popular land-based developers like IGT and Aristocrat, WMS started out developing mechanical slot machines and pinball games. The company was first established in 1943 by Harry Williams, who invented the tilt mechanism for pinball machines. It was a long time before WMS entered the gambling market, as the company did not create its first slot machine until the 1990s. Since then, the company has become a leader in the casino gambling market, developing some of the most popular games in the market.
