Atamahane
Atamahane 「頭跳ね」, known in English as the "head bump" rule, is a rule that only allows one winner per hand. When two or more players declare ron on the same tile, only the player closest in turn order to the discarder wins - the other players get nothing.[1] For example, if West deals in, North has priority, followed by East.
The alternative to atamahane is allowing double ron. Some rules allow double ron, but abort the hand on a triple ron. Other rules allow double and triple ron. In rulesets where double/triple ron are allowed, the riichi bets are typically subject to atamahane (e.g. if West deals in to North + South, North gets the riichi bets, but both players win.)
Atamahane is relatively more common in real life rulesets, while double ron is relatively more common in online rulesets. However, this is not a hard rule, so offline rulesets can use double ron and vice versa.
