The game features specific rules for number tiles, requiring at least a 2-number gap between them and prohibiting consecutive numbers within the same suit. Players must also gather all Wind and Dragon tiles to achieve victory. With engaging gameplay that tests your Mahjong skills, Thirteen Fray offers a strategic challenge for both newcomers and seasoned players.
