Dominoes is a family of boardgames 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 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. The traditional Sino-European domino set consists of 28 dominoes, featuring all combinations of spot counts between zero and six. A domino set is a generic gaming device, similar to playing cards or dice, in that a variety of games can be played with a set.
