The Company History Up To 2024

The company history for WMS casino software dates all the way back to 1943 when the company began producing pinball machines. In the 1970s, they branched out into coin-operated arcade games such as Paddle Ball, Defender, and Robotron: 2084. In 1988 they acquired Bally/Midway (Midway were known for titles like Mortal Kombat). Williams Interactive stopped creating pinball machines in 1999 when they turned their focus to slots and gambling machines.

The company was initially called Williams Gaming and in 1991 the production of video lottery terminals began. It was in 1994 that the company entered the slot machine market and it has been producing some of the best Las Vegas casino slots for both land-based and online casinos using Williams Interactive software ever since.

A big focus for Williams Interactive was the creation of slot machine cabinets for brick and mortar casinos and these would be sold or leased to different operators. In 1999 the company named changed from Williams Gaming to WMS Gaming. In 2000, WMS introduced their Monopoly series of slots where became a huge hit and because of this, they secured licenses for other big brands such as Men in Black, Star Trek, and The Wizard of Oz. In 2013, Williams Interactive merged with Scientific Games and it became a fully-owned subsidiary of Scientific Games.

The higher the RTP the better chance you have of winning over the long term. RTP stands for Return To Player and is the percentage amount you can expect to win. For example, if you play one of our top 10 WMS casino slots that has an RTP percentage of 96% it means that you will win $0.96 for every $1 wagered over a period of time.
