Seattle-based game maker Big Fish said late Monday that it has launched its real money, betting game in the United Kingdom. Big Fish said its new app, Big Fish Casino UK, allows users to make bets with real money while playing the iOS game. The game--which runs on the iPhone, iPad, and iPod touch--is being powered by a deal with gaming provider Betable. Big Fish said the casino game has more than one million worldwide monthly active players; the new, real-money betting feature is available for users in the UK App Store. Big Fish had announced its plans to start offering real money casino gambling in August.
