How to play:
Choose a mode and table type, then enter a match under standard Japanese riichi rules with optional OVERLORD-themed settings.
Draw and discard tiles each turn to form valid yaku; track dora and wait shapes to maximize hand value.
Call chi, pon, or kan to adjust your hand’s tempo, or stay closed to enable riichi and higher-scoring hands.
Declare riichi when in tenpai, place the stick, and win by ron or tsumo to score points and swing the round.
Defend when pressured by reading enemy discards, folding with safe tiles, and avoiding furiten traps.
Unlock and equip collaboration cosmetics, complete event missions, and climb ranked tiers in multiplayer or practice in solo modes.
