End game scenarios

Game ends before any hand rotation.

For Japanese mahjong, the game may end according to different scenarios. Normally, the last hand of the game is in South 4 (for tonpuusen, it is East 4). This last hand is generally designated as oorasu. However, depending on the rules, the game may very well not end in South 4 (East 4); and it may extend into an extra round. Finally, the game could end well before oorasu, when a player's points drop into the negatives.

Goal score

Both a start score and a goal score are set for games. The start score is self-explanatory, indicating the starting number of points for each player. The goal score is the minimum number of points required for the game winner to attain after the final regular hand of the game. Under most settings, players begin with 25,000 points and aim to be the highest score above 30,000 points. Of course, these point settings can change in accordance to club, parlor, or tournament hosts.

Enchousen

Enchousen 「延長戦」 is an extra wind round. The extra round functions like an "overtime sudden death period" This extra round continues, when no player scored above the goal score after the final regular hand. The instant a player scores above the target points with a winning hand, then the game ends immediately; and the same player wins the game. However, ryuukyoku cannot end the game. For a regular hanchan game, this extra round is indicated as the West round. For tonpuusen, the South round takes on this role.

Tobi

Tobi 「トビ」 pertains to negative scores. In general, games end when a player falls below zero points. However, some game settings allow the continuation of the game despite the negative scores. This is particularly applicable to televised games, which do not desire the premature ending to a game.

Oorasu

Oorasu 「オーラス」 is designated for the last dealer of the game; the term is derived from all last. This is the South 4 hand; for East only, it is the East 4 hand. By this point, every player has had the chance to be the dealer twice (once for East only). Naturally, if the last dealer wins, renchan may occur for another hand. Though, the game may end if the last dealer happens to be the points leader; or if the other players force a wind rotation. This depends on agariyame.

Agariyame

Agariyame 「和了り止め」 is a specialized rule applied at oorasu, where the last dealer can end the game, while holding the lead after one hand. This decision enables the last dealer to prevent other players from additional chances of improving their point standing. Naturally, the last dealer with the lead secures the win for the whole game. Otherwise, the same player may make the call to continue an additional hand, or renchan. The game can end, if a player aside the dealer wins the hand.

When the rule setting is set to "nashi", then the game continues until one more wind rotation is invoked. In this case, the last dealer has the privilege of retaining the dealer seat to continually attain points until a proper end to the game.
