Game of several variations played with a set of flat rectangular blocks (dominoes) whose faces are divided into two equal parts that are blank or bear from one to six dots arranged as on dice faces.
The usual set consists of 28 pieces. Dominoes in China may date to the 12th century AD; the Eskimos have also long played a domino-like game. There is no record of dominoes in Europe before the mid-18th century. The principle in nearly all modern dominoes games is to match one end of a piece to another that is identically or reciprocally numbered. The game may be set at 50 or 100 points.
