'''Suukantsu''' {{kana|四槓子}} is a standard [[yakuman]] obtained when the hand has called [[kan]] four times. As a result, it always has a [[Tanki|hadaka tanki machi]], because four [[naki|tile calls]] are required. Suukantsu is the rarest hand in the game, even rarer than [[tenhou and chiihou|tenhou or chiihou]]. It is also the longest, requiring 18 tiles total. | |||

This yakuman requires four kan calls. As a result, the hand in [[tenpai]] always uses [[Tanki|hadaka tanki]]. In order to call a single kan, a player must draw at least 3 out of 4 of a single tile type under any of these three scenarios: | |||
* A player has a pair and calls pon, then draws the fourth to [[shouminkan|call kan]]. | |||
* A player has a closed triplet and [[daiminkan|calls kan]] on a discarded fourth. | |||
* A player draws all four of a tile type and [[ankan|calls kan]]. | |||
For this yakuman, a player must repeat any of those kan calls four times. This yakuman is the most difficult yakuman to attain tenpai, let alone score. | |||
*You must obtain a total of 4/4 tiles of four different types. If any tile is rendered unavailable (e.g. in an opponents hand, in the dead wall), the hand is practically impossible. | |||
*You must obtain 3/4 of those tiles by self draw. That feat is already worth a yakuman, that being [[suuankou]]. In addition, a hand that could be suuankou is unlikely to call an open kan, because it's much easier to win with suuankou. | |||
*If any other player has called kan, the hand becomes impossible. If playing with abortive draws, this will trigger [[suukaikan]]. If playing without, then players are still only allowed a combined total of 4 kans in one game. | |||
*Calling four kans adds a total of four kan dora, which will greatly boost the value of others' hands. A player may not want to kan even once in order to avoid the extra dora. | |||
*Calling four kans immediately reveals you have a yakuman hand, so players are likely to defend. | |||
*The hand always has a hadaka tanki wait. In addition to being difficult to win off, it leaves you with no room to defend. | |||
Finally, like any other yakuman, another player could have a faster hand and win before you. | |||

Despite the greater degree of difficulty and exceptionally low frequency of occurrence, the value remains as that of the other single yakuman. | |||
