Dominos, a game which has been traced by some authors to the Greeks, Hebrews, and Chinese. Its first appearance in western Europe is not ancient, it having been introduced into France from Italy about the middle of the last century. The domino is a small flat oblong of wood, ivory, or bone, divided on one side by a line into two compartments. Each of these is marked with a certain number of dots, from 1 to 6, or is left a blank, so that upon each domino there is a different combination of numbers. The game is played with 28 dom-inos, the reverse sides of which are unmarked and all alike. This side being up, each player takes an equal number of the dominos. The person who has drawn the one which has the highest number of points puts it down; the next domino played has to be one with a number the same as one of the two numbers presented by the first, and the two similar ends are joined. The next may match the remaining number of either the first or the second domino, and thus the game continues till one player has put down all his pieces. There are a number of variations in the mode of playing this game.

The combinations are neither very varied nor intricate, and yet it requires memory and calculation.
