While other competitors may match its overall selection, Tropicana has most of them beat when it comes to bingo. The site, which is powered by UK software provider GameSys, offers players a variation of bingo called 90 ball bingo. But while the game is highly popular overseas, it hasn’t really gained that much traction in the US. Even so, with GameSys’s experience in offering online bingo in the UK, it was a no-brainer to add it to their US offering for those interested.
