End game scenarios

Normally, the game ends after the dealer loses in South 4 (for hanchans) or East 4 (tonpussen). However, depending on the rules, the game might not end. Alternatively, the game can end early if a player runs out of points.

Game ends before any hand rotation.

Oorasu

Oorasu 「オーラス」, or "all last", is the term used for the last round of the game. This is South 4 for hanchans, and East 4 for East-only rounds. Naturally, if the current dealer wins, the game can go on for another renchan. Once the dealer fails to renchan, and the top player has reached the goal score, the game ends.

Depending on the ruleset, the dealer may be allowed (or forced) to end the game once they are in first place. This is a rule known as agariyame.

Goal Score

The target score is the minimum score that the top player must have in order to end the game. It is set before the game starts. Usually, players start with 25,000 points with a goal score of 30,000 points - but this can change depending on the ruleset.

Enchousen

If first place's points are below the goal score by all last, the game starts an enchousen 「延長戦」, or an extra "sudden death" round. During enchousen, when a player wins a hand and scores above the goal score, the game ends. However, ryuukyoku cannot end the game.

Rulesets will differ on how many enchousen rounds a game can go. Some rulesets only allow one round maximum: if the game goes on to West 4 (hanchans) or South 4 (Tonpuusen), the game ends, even though no one reached the goal score. Other rules do not have a target score and thus do not have enchousen.

Tobi

Tobi 「トビ」 is a rule that ends the game once a player fall below 0 points. Some game settings disable tobi, allowing the game to go even though a player is at negative. This is particularly applicable to televised games, which do not desire the premature ending to a game.

Agariyame

Agariyame 「和了り止め」 is a specialized rule which dictates what the dealer can do when they are first place in all last. There are 3 main settings:

• A 1st-place dealer must start a new renchan once they win in all last.
• A 1st-place dealer can choose to end the round once they win in all last.
• A 1st-place dealer must end the game once they win in all last.

If tenpai-renchan is enabled, the same rules apply for tenpai hands as they do for winning.
