Founded in 2007, Simon Says Casino is one of the earliest gambling operators of the new wave. It is also one of the few that chose Rival gaming as a main software provider for its games. The casino is licensed and regulated by the government of Curaçao while the games are audited for fairness by TST.

The decision to stick to a single niche software developer has resulted in a small collection of games for Simon Says Casino. Slots dominate the lineup, followed at a distance by table games and video pokers. It is possible to play them against the random number generator, in the browser or as downloadable content.
