A '''ba''' {{kana|場}} or '''wind round''' is a complete round of play, where each player is the [[oya|dealer]] at least once barring any premature [[End game scenarios|end game conditions]]. Each round of play is associated with a single cardinal direction and its corresponding [[bakaze|wind tile]]. For the remainder of this article, the term ''round'' will refer to a wind round, although it is sometimes used to mean [[kyoku]] instead.

Normally, a match is played for an agreed-upon number of rounds. Traditionally, this was four rounds (an [[iichan]] {{kana|一荘}}), one for each wind. This is still common in Chinese variants. In modern Japanese play, a match is normally played for two rounds (a [[hanchan]] {{kana|半荘}}) or sometimes for only one round (a [[tonpuusen]] {{kana|東風戦}}). Some rules sets allow the match to extend into additional wind rounds if no player has met the [[goal score]].

When the deal rotates to the fourth time, back to the player who was originally the dealer, the round ends and either the game is over or a new round begins.

The total game length is dependent on the number of game rounds used and the rules pertaining to the end of games.
 
=== Additional rounds ===


In many rulesets, a goal score must be reached by at least one player for the game to end. If this score is not met by any player at the end of the normal rounds of the game, the game proceeds into an '''additional round''', or '''[[enchousen]]''' {{kana|延長戦}}. This round is usually played as sudden death: the game end as soon as a player reaches the goal score. Usually, but not always, the game will also end at the end of the additional round regardless of score; and the game will not proceed into a second additional round.

'''Kyoku''' {{kana|局}} is the identifier for each mahjong hand played during the game.  It uses a combination of the wind round, a number 1-4, and the '''[[honba]]''' count {{kana|本場}}.  As an example, the very first hand is always East Round 1, Honba 0 {{kana|{{kyoku|E|1|0}}}}.  As the first hand of the game, it is impossible for it to have an alternative designation.  All subsequent hands may differ due to the different ways the game plays out.
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.
