===Playing Heaven and Nine===
Playing Heaven and Nine (打天九) is a multi-trick game for 4 players.<ref>Celko, Joe and John McLeod. [https://www.pagat.com/tile/cdom/tiengow.html Tien Gow] at [[pagat.com]]. Retrieved 24 January 2016.</ref> All tiles are distributed by the banker so each player gets eight. The banker leads the first trick with a single, double, triple, or quadruple trick and the others must play out with an equal number of tiles. Players that are unable to beat the trick discard their tiles face down (this is characteristic of some [[trump (card games)|trump]]less trick-taking games like [[Madiao]] and [[Ganjifa]]). The winner leads the next trick. The player who takes the last trick or multi-trick becomes the next banker. Players who have not won any of the first seven tricks automatically lose the last trick regardless of the strength of their final tile.

In double tricks, there are two additional suits, mixed and supreme:
*Mixed: Heaven and a Nine; Earth and an Eight; Mankind and a Seven; Harmony and a Five
*Supreme: Six and Final Three

As the supreme suit consists of a single pair, it is unbeatable if led but considered a discard if not led.

In triple and quadruple tricks these are the only valid combinations: Heavens and Nines; Earths and Eights; Mankinds and Sevens; Harmonies and Fives

Triple tricks have a rule that a triplet consisting of two civil and one military tiles can only be beaten by a triplet consisting of the same suit compositions. Likewise, a triplet consisting of two military and one civil tiles can only be beaten by the same.

There are complex rules to the game play and scoring. There is an accumulating multiplier to the winning and loss as the game proceeds. There are bonuses for winning the last trick with certain methods and for different types of slams. It can be adapted to be played with a [[standard 52-card deck]].

The earliest surviving rules were written by Pan Zhiheng around 1610.<ref name="Lo" /> In this version (鬥天九), triple and quadruple tricks were not allowed and Heavens can beat Nines and the Supreme pair. There were also versions for two or three players in which some of the tiles remain undistributed. His rules are more similar to the ones used in northern China during the early 20th century than the Cantonese rules that are dominant in the present. They are also very similar to another game simply called dominoes (骨牌) played in many parts of China.

Bagchen is a Tibetan variation played with a double set of dominoes.<ref>McLeod, John. [https://www.pagat.com/tile/cdom/bagchen.html Bagchen] at [[pagat.com]]. Retrieved 5 April 2016.</ref> Daaluu (Даалуу) is a variation in Mongolia that also uses a double set and plays similarly to [[Khorol (game)|Khorol]].<ref>[http://www.touristinfocenter.mn/cate16_more.aspx?ItemID=89 Mongolian games] at tourist info center.
