Domino

Domino (or dominoes) 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.

The traditional set of dominoes contains one unique piece for each possible combination of two ends with zero to six spots, and is known as a double-six set because the highest-value piece has six pips on each end (the "double six"). The spots from one to six are generally arranged as they are on six-sided dice, but because there are also blank ends having no spots there are seven possible faces, allowing 28 unique pieces in a double-six set.

The most popular type of play are layout games, which fall into two main categories, blocking games and scoring games.

-Most domino games are blocking games, i.e. the objective is to empty one's hand while blocking the opponent's. In the end, a score may be determined by counting the pips in the losing players' hands.
-In scoring games the scoring is different and happens mostly during game play, making it the principal objective.
