Domino is a board game in the course of which a chain of dice (bones, stones) is built, which are in contact with halves with the same number of points, indicating the number of points. This term also refers to other board games, the purpose of which is to place dice on a table or on a special playing field with one or more symbols applied to them so that they touch each other with the same name symbols. Each character in the set usually has a numerical value. The sum of the points of all the dice in one set of dominoes is 168.
