"Note 1" : A common rule in Singapore dictates that any player who collects all 3 triplets of the 3 元 tiles, either by having them in your hidden hand, or by performing Pong (碰 "pèng") to obtain exposed triplets, can declare himself to have fulfilled the 大三元 combination. The combination of the hidden hands, under this rule, does not matter. Invoking this rule when a player collects all 3 triplets earns that player 5 points, instead of 10. Some playing circles consider this a special hand, whereby all players pay double that of the limit, regardless if the hand was won on a self-picked (自摸) tile or not.
