Taiwanese 16-Tile Mah Jong

This rule preset represents modern Taiwanese Mah Jong, where the most prominent feature is one additional set that is needed in a winning hand. Thus each player is given 16, instead of 13 tiles in the dealt hand (dealer being given naturally one additional tile to start the deal). A winning hand must contain 5 sets of Chows/Pungs/Kongs and a pair.

As for pattern selection, the Taiwanese Mah Jong is fairly classical, though some patterns have been added and some removed because of the additional set (e.g., Nine Gates cannot be collected in 16-tile Mah Jong; on the other hand, a limit is paid for patterns like Five concealed triplets). In addition, certain new patterns typical to New Style have been adopted, e.g., Three Chows of 1 suit, step 3, Two concealed triplets, Little Three Winds, Big Three Winds, Exposed hand and No Honors

As in all modern versions of Asian Mah Jong, only the winner is paid. But unlike most of the other modern Chinese versions, the Taiwanese rules do not use a faan-laak settling table to determine the final score. Instead, scores for patterns are simply added up. The payoff scheme is unique (though also used in Chinese Official Mah Jong): if the winner goes out self-drawn, all losers pay the winner directly the amount of his final score, but if the winner goes out on a discard, discarder alone pays the amount of the winner's final score (not for all losers but just for himself). 

Other features not normally seen in other Chinese versions of Mah Jong include a unique system of rewarding the East winner, especially for going out on continued deals: instead of using the classical East pays/receives double system, a cumulative bonus for continued deals is used. The bonus is paid to the East winner by each loser if the winner goes out self-drawn, and by the discarder alone, if the winner goes out on a discarded tile; on the other hand, if non-East wins self-drawn or if East discard the winning tile, East must pay himself the specified bonus to the winner.

16-tile version of Mah Jong is played also in Philippines, often with more classically oriented rules using a point-double scoring system, where East receives and pays double, and losers pay each other according to the difference of their final scores.

Note: As the Taiwanese Mah Jong does not use a settling table to specify the final score, it is very typical that scoring assignments vary greatly from version to version.
