The winning condition may vary between closed-hand only, or opened-hand allowed. Though even with an openable choice, this hand is still pretty rare, and really hard to accomplish. The difficulty comes from the process of collecting those twelve tiles with continuous numbers in one suit, while only the [[kamicha]] can help to feed the tiles. This is also why this yaku generally doesn't apply the [[kuisagari]] rule to downgrade the value of an opened hand, which is usually widely applied for shuntsu-based yakus. | The winning condition may vary between closed-hand only, or opened-hand allowed.
