Hanchan

Un hanchan 「半荘」 est un format de partie de mahjong japonais. Une partie typique comprend deux tours appelés Est puis Sud. Même si une partie se termine prématurément, par exemple lors de la faillite d'un joueur, la partie est malgré tout considérée comme complète. Pour des parties plus courtes il est possible d'adopter le format tonpussen 「東風戦」 (vend d'Est uniquement).

À l'exception du cas de la faillite, le nombre minimum de mains jouées est de 8. La longueur de la partie réelle varie ensuite selon le nombre de redonnes et certains autres aspects. En prenant en compte le cas de la faillite, il est bien sûr possible que la partie se termine au premier tour.

Une partie typique commence avec le tour d'Est ou tonkyoku 「東局」. Une fois terminé, la partie passe au tour du Sud ou nankyoku 「南局」. Il peut arriver que la partie se poursuive au tour d'Ouest ou shaakyoku 「西局」. Pendant la partie, un jeton de donneur est utilisé pour tenir le compte du donneur initial ou parfois du donneur de la donne courante. Il montre aussi le tour auquel on se trouve (Est ou Sud).

Appellations des donnes

Kyoku 「局」 est l'appellation de chaque donne jouée pendant la partie. Il fait appel à une juxtaposition du vent du tour, du numéro de la donne, et du décompte des honba. Par exemple, la première main est toujours Est donne 1, honba 0 「 東 1 局 0 本場」. En tant que première donne de la partie, il est impossible qu'elle ait une appellation différente. Les donnes suivantes peuvent varier selon les différentes façons dont peut se dérouler la partie.

For every wind rotation, the designation for the wind round increases by one. After East Round 1, then the game moves onto East Round 2. This indicates that the player to the right of the initial dealer has become the new dealer. This continues onto East Round 4, which is the last round for East. If the game continues from here, then the designation becomes South Round 1. Here, the initial dealer once again became the dealer. Only this time, it is the South Round. Most games end after South Round 4. If necessary, the game continues into the West Round.

Barring certain conditions, the dealer has the ability to retain position and deny a wind rotation in the next hand. In this case, renchan occurs.

Renchan

Renchan 「連荘」 are additional hands, by which the wind seating do not rotate. Under English terminology, a renchan may be considered as a "bonus hand". This is possible when the dealer wins a hand, an abortive draw occurs, or the dealer is tenpai at exhaustive draw. This is a clear advantage to the dealer position, with the ability to continually retain the dealer position given the two conditions. Comebacks are very much possible and doable from taking advantage of the dealer seat.

In the event when the wind seating does not change, then the honba count increases by one. For each honba, the hand value for any player is increased by 300 points. To mark honba, the dealer uses a 100 point stick to mark the number of renchan currently. The points are used as markers only temporarily and is not spent by the dealer. When the dealer seating rotates via a hand winning, the dealer receives the markers back. A game cannot end with a renchan on board. A seat wind rotation is part of the end game criteria. Under specific conditions, this honba count is able to increase even during a wind rotation.

In the event of chombo, the wind seating may rotate if the dealer commits the penalty. Otherwise, it may not without an increase to the honba count depending on rule specifications.

End of game

Game ends before any hand rotation.

The game may end according to different scenarios. Normally, the last hand of the game is in South 4 (for tonpussen, 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.

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.

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 target points (typically 30,000) after South 4. 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 tonpussen, the South round takes on this role.
