Dominoes (or
dominos) is a game played with rectangular "domino" tiles. 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, colloquially nicknamed
bones,
cards,
tiles,
tickets,
stones, or
spinners. 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. 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.
