All variants
Rules and table scoring
  1. 108 tiles: characters, bamboo and dots, without honors or flowers.
  2. Deal 13 tiles each, plus one for the dealer. Remove three tiles of one suit from each hand. Subsequent hands use ten concealed tiles plus a draw, winning with three sets and a pair.
  3. Declare a void suit. Discard tiles of that suit first and hold none of it when winning. No chows; pung and kong are allowed.
  4. A win has priority over pung/kong, which have priority over chow. Multiple discard wins are allowed. Concealed kongs and added kongs draw a replacement tile. An added kong can be robbed.
  5. After winning, reveal and lock the waiting hand. Keep drawing: win again on suitable tiles, otherwise discard the drawn tile. No new exposed melds; a concealed/added kong is legal only if the waiting tiles remain unchanged.
  6. Table fan: basic win zero, all pungs one, seven pairs/full flush two, a root or kong bloom one, and self-draw one. Combinations stack. Points are 2 to the fan power, capped at four fan in Sichuan and eight in other tables.
  7. Kong payments at this table: an exposed discard kong receives two points from its discarder; an added kong receives one from each other active player; a concealed kong receives two from each. Discard wins are paid by the discarder; self-draw wins by all other active players.
  8. At a wall draw, remaining players are checked for the void suit and readiness: a flower pig pays 16 to each clean remaining player; an unready hand pays each ready hand its highest available capped win.
  9. The room starts with a five-minute deal limit and 40 seconds per turn. A timed-out turn is covered by a bot; an unfinished deal at the time limit ends without declaring a winner.
