Riichi. Riichi (Japanese) mahjong is the modern competitive ruleset centered on the riichi declaration, mandatory yaku, and han/fu scoring — 136 tiles, four players, no flowers in play.
Singaporean. Singaporean mahjong plays much like Hong Kong mahjong with a 148-tile set (144 plus four unique animal bonus tiles) and doubling-based scoring whose minimum and limit vary by house rule.
