Limit and Special hands – American hands

These hands are typically acknowledged in American Mah Jong, where the focus is in collecting special hands. Note that many hands are based on the way the American rules associate suits with Dragons: Bamboos are associated with Green Dragons, Characters with Red Dragons, and Dots with White Dragons. In addition, the Bamboo suit is divided in two based on use of red in the tiles: the red tiles are 1, 5, 7 and 9 and green tiles 2, 3, 4, 6 and 8.

Simple Gates
(a.k.a. Chinese Hand)
Note: When prohibition of mixed suits is used (as in American and Australian rules), all tiles of this hand need to be from one suit  (unless an exception is specified in the Exceptions dialog box). In its one-suit version this hand is known in several Western rules as Nine United Sons, Heavenly Gates, etc. Do not confuse this hand with the classical Nine Gates hand (which is also called Nine United Sons) from which the Western versions are obviously derived by bad interpretation. Nine Gates, unlike the Western gate hands, is a regular hand, for which the arbitrary restriction for pairing one of the simples is never applied.
