Suukantsu
Suukantsu 「四槓子」 is a standard yakuman, where the hand has collected kan four times. As a result, this hand always has uses a hadaka tanki machi, because four tile calls are required. Of all the hands possible, suukantsu is the rarest. Unlike all the other patterns, this yakuman cannot afford to have particular tiles unavailable via discards, the dead wall, or used in other player's hands.

Viability
This yakuman requires four kan calls. As a result, the hand in tenpai always uses 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 call kan.
- A player has a closed triplet and calls kan on a discarded fourth.
- A player draws all four of a tile type and 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. If any of those tiles are rendered unavailable for kan, it forces the hand to seek other possible tiles to call kan with; or the hand is made virtually impossible.
Value
Despite the greater degree of difficulty and exceptionally low freqency, the value remains as that of the other single yakuman.
