Riichi Mahjong

A Japanese variant of Mahjong focused on building a valid scoring hand through specific combinations (yaku) and bonuses (dora). Players draw and discard tiles to complete melds while tracking a one-yaku minimum to claim victory, using riichi bets to lock a ready hand and potentially access hidden ura-dora. The game uses a complex scoring system of han and fu to convert hand composition into points, and includes special rules such as abortive draws and dead-wall dora indicators. Gameplay emphasizes hand construction, timing of riichi declarations, and score calculation rather than simple pattern completion.
