'''Ippatsu''' {{kana|一発}} is a yaku completely dependent on [[riichi]]. | '''Ippatsu''' {{kana|一発}} is a yaku that is completely dependent on [[riichi]]. After declaring riichi, if the player wins before their next discard, and before anyone makes a [[naki|tile call]], then ippatsu is awarded. | ||
You must declare riichi to score ippatsu, so a hand can never have ippatsu by itself. The earliest possible chance to win with ippatsu comes from the shimocha's discard (player to the right). The latest possible chance to win with ippatsu is with the player's next drawn tile after the riichi declaration. | |||
While ippatsu is generally considered to be a standard yaku, certain [[rule variations|rulesets]] do not use it, in order to reduce variance and lower the value of a riichii. In general, when sitting down to play a game, ippatsu is counted unless otherwise specified or agreed on before the game. | While ippatsu is generally considered to be a standard yaku, certain [[rule variations|rulesets]] do not use it, in order to reduce variance and lower the value of a riichii.

In order for ippatsu to be counted, the hand must win before the hand in riichi discards its next tile. | In order for ippatsu to be counted, the hand must win before the hand in riichi discards its next tile. Furthermore, no interruption to the turn must occur. This means that [[Naki|tile calls]] will immediately end the chance for ippatsu. This includes any calls for [[kan]] ''except'' for a robbed kan ([[chankan]]). In [[sanma]], the call for [[kita]] also denies ippatsu. If the riichi player declares kan or kita, ippatsu is still denied. | ||
To repeat: even if a hand is won before the next discard, if a call is made, ippatsu is denied. Thus, players can purposefully make tile calls in order to disrupt another player's chance for ippatsu. | |||
