Tsumo
Also called: 自摸, self-draw, zimo
Winning by drawing your winning tile yourself from the wall.
Tsumo is winning by drawing your own winning tile from the wall — no opponent involved. In Riichi, tsumo gives a Menzen Tsumo bonus on closed hands (1 han). In other variants, tsumo typically pays a flat bonus split across all opponents. The Bloody Battle (Sichuan) variant pays self-draws especially aggressively because they continue the round.
