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==
Normally, the game ends after the dealer loses in South 4 (for [[hanchan]]s) or East 4 ([[tonpussen]]). However, depending on the rules, the game might not end then and there. In addition, a game can end early if a player runs out of points.
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, [[jansou|parlor]], or [[tournament]] hosts.


===Enchousen===
== Rule overview ==
'''Enchousen''' {{kana|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 [[scoring|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.
A game can end under the following circumstances (though it can vary by ruleset):
* It is [[#Oorasu|all last]] (East 4 for [[tonpuusen]], South 4 in [[hanchan]]), the dealer did not [[renchan]], and at least one player is above the [[#Goal Score|goal score]].
** If no player is above the goal score, the game continues for a maximum of one wind round, known as [[#Enchousen|enchousen]]. If someone reaches the goal score by winning then, the game ends immediately. After South 4 / West 4 ends, the game ends even if nobody reached the target score.
* If someone [[#Tobi|falls below 0 points]], the game ends immediately.


==Tobi==
If a ruleset does not use a goal score, the game ends after all last.  
'''Tobi''' {{kana|トビ}} pertains to negative scores.  In general, games end when a player falls below zero points.  However, [[Scoring_variations#Tobi|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==
'''Oorasu''' {{kana|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 [[tonpuusen|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.
'''Oorasu''' {{kana|オーラス}}, or "all last", is the term used for the last round of the game, barring [[renchan]]. This is South 4 for hanchans, and East 4 for East-only rounds. Once the dealer fails to [[renchan]], and the top player has reached the goal score, the game ends.
 
===Agariyame===
'''Agariyame''' {{kana|和了り止め}} is a [[Rule_variations#Agariyame|rule]] which dictates whether the dealer can [[renchan]] or not during all last. There are three main settings:
* A 1st-place dealer must end the game once they win in all last. Non-1st place dealers must renchan if they win. (Most notably, this is the rule used in online clients like [[tenhou.net]] and [[Mahjong Soul]].)
* A dealer must start a new renchan if they win in all last, even if in 1st place.
* Any dealer, regardless of place, can choose to end the round once they win in all last.
 
If [[tenpai]]-renchan is enabled, the same rules apply for a dealer in tenpai as they do for winning. Regardless, this setting affects all players' ability to change placement.
 
==Goal Score==
The goal score, or 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. Some rules do not have a goal score.
 
===Enchousen===
If first place's points are below the goal score by all last, the game starts an '''enchousen''' {{kana|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.


==Agariyame==
Most, if not all, rulesets with a goal score only allow a maximum of one wind round's worth of enchousen. If the game goes on past West 4 (hanchan) or South 4 (tonpuusen), the game ends, even though no one reached the goal score. While a few house rules may allow indefinite enchousen, by default, assume that it lasts only 1 wind round maximum.
'''Agariyame''' {{kana|和了り止め}} is a [[Rule_variations#Agariyame|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 [[gyakuten|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.
==Tobi==
'''Tobi''' {{kana|トビ}} is a rule that ends the game once a player falls below 0 points. [[Scoring_variations#Tobi|Some game settings]] disable tobi, thus allowing the game to continue even when a player goes negative. Tobi is often disabled for televised matches, which do not desire a premature ending to the game.

Game ends before any hand rotation.

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 then and there. In addition, a game can end early if a player runs out of points.

Rule overview

A game can end under the following circumstances (though it can vary by ruleset):

  • It is all last (East 4 for tonpuusen, South 4 in hanchan), the dealer did not renchan, and at least one player is above the goal score.
    • If no player is above the goal score, the game continues for a maximum of one wind round, known as enchousen. If someone reaches the goal score by winning then, the game ends immediately. After South 4 / West 4 ends, the game ends even if nobody reached the target score.
  • If someone falls below 0 points, the game ends immediately.

If a ruleset does not use a goal score, the game ends after all last.

Oorasu

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

Agariyame

Agariyame 「和了り止め」 is a rule which dictates whether the dealer can renchan or not during all last. There are three main settings:

  • A 1st-place dealer must end the game once they win in all last. Non-1st place dealers must renchan if they win. (Most notably, this is the rule used in online clients like tenhou.net and Mahjong Soul.)
  • A dealer must start a new renchan if they win in all last, even if in 1st place.
  • Any dealer, regardless of place, can choose to end the round once they win in all last.

If tenpai-renchan is enabled, the same rules apply for a dealer in tenpai as they do for winning. Regardless, this setting affects all players' ability to change placement.

Goal Score

The goal score, or 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. Some rules do not have a goal score.

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.

Most, if not all, rulesets with a goal score only allow a maximum of one wind round's worth of enchousen. If the game goes on past West 4 (hanchan) or South 4 (tonpuusen), the game ends, even though no one reached the goal score. While a few house rules may allow indefinite enchousen, by default, assume that it lasts only 1 wind round maximum.

Tobi

Tobi 「トビ」 is a rule that ends the game once a player falls below 0 points. Some game settings disable tobi, thus allowing the game to continue even when a player goes negative. Tobi is often disabled for televised matches, which do not desire a premature ending to the game.
