Riichi: Difference between revisions

Line 15:

'''Riichi''' {{kana|立直}} or {{kana|リーチ}} is the most commonly used [[List of yaku|yaku]] in the game. This yaku may apply to any closed hand and may be declared upon achieving ''[[tenpai]]''. Due to its common usage, various specific game scenarios must be considered when using riichi.

Unlike other yaku, the call for riichi operates at a player's discretion and is certainly not mandatory. Players may simply opt not to call riichi and retain the secrecy of a hand's tenpai status.

Line 27:

It is not allowed to declare riichi when less than four tiles remain in the wall. The player must be able to draw one more tile in an uninterrupted set of turns. The absolute last chance to call riichi is when the player has a chance to score riichi, [[haitei]], [[ippatsu]], and [[mentsumo]].

===Noten riichi===

A player may actually declare riichi with a noten hand. This is a '''noten riichi''' {{kana|ノテン立直}}. This type of play is highly not advisable. If and when the hand results in [[ryuukyoku]], then it is required of the player to reveal the hand to show tenpai. The noten riichi would naturally show noten; and it is subject to [[chombo]]. Of course, computer based play is usually programmed to prevent players from making such a riichi declaration.
