Mansion88, also known as M88, is an Asia-focused online betting brand launched in 2007 and operated by Mountain Breeze Limited. The site combines a full sportsbook, casino, live casino and poker-style products under one wallet, backed by long-term deals with major sports properties such as La Liga, AC Milan and the Badminton World Federation, plus ambassadors like Manny Pacquiao.
The casino lobby features around 2,500+ titles from well-known providers, including slots, jackpots, table games and multiple Asian-style live dealer studios. On the sportsbook side, Mansion88 offers deep coverage of football, basketball, esports and niche Asian markets, with a strong in-play section and competitive odds for major leagues.
However, Mansion88 operates on offshore licenses from the Philippines and Vanuatu rather than a UKGC license and is regularly promoted as a non-GamStop option. Review sites and player forums highlight serious issues such as unfair or restrictive terms and conditions, delayed or voided withdrawals (including crypto), uncredited deposits and slow or unhelpful customer service. Mansion88 can appeal to high-volume bettors in Asia, but it carries a higher risk profile than fully regulated UK or EU operators.
