Dominoes 03-01 (reversed) pairs, and generic backsides. Dominoes Dominoes is a family of tile-based games played with rectangular "domino" tiles. Each domino is a rectangular tile with a line dividing its face into two square "ends". Each end is marked with a number of spots (also called "pips", "nips", or "dobs") or is blank. The backs of the dominoes in a set are indistinguishable, either blank or having some common design. The domino gaming pieces make up a domino set, sometimes called a "deck" or "pack".

Chinese dominoes a throw of two six-sided dice. Each combination is only used once, so there are 21 unique possible patterns. Eleven of these 21 unique patterns are repeated to make a total of 32 tiles in a Chinese dominoes set. The tile set consists of 32 tiles in two "suits" or groups called "military" and "civil". There are no markings on the tiles to distinguish these suits; a player must simply remember which tiles belong to which group. The tile set contains two each of eleven civil suit tiles (6-6, 1-1, 4-4, 1-3, 5-5, 3-3, 2-2, 5-6, 4-6, 1-6, 1-5) and
