In the case of sangenpai (dragon tiles), any player may collect sets of these tiles and attain this yaku. The collection of all three by one player leads to the daisangen yakuman.
With regards to kazehai (wind tiles), the yaku operates in a similar fashion but differently. First of all, at any time, players are assigned a particular "wind seat", relative to the dealer position, who is always seated East. To count for this yaku, players must collect their own set of wind tiles. If the wind is not of their seat wind, then the set is considered to be "off wind", which does not count as yaku. Furthermore, the game has an assigned round wind. Marked by the dealer indicator, the round wind applies as yaku to any player. The first round is almost always East, followed by South. Occasionally, the game moves into West round as well, where the West wind counts as the round wind.
