Domino is a popular game played with rectangular tiles called dominoes. Each tile is divided into two squares, each marked with a number of dots, similar to a die. Players take turns placing tiles on a flat surface, matching the numbers on the ends of the tiles. The objective is to be the first to play all your tiles or to block your opponents from making a move. The game can be played in various styles, including block and draw games, and can accommodate different numbers of players. Dominoes can also be used for other activities, such as creating intricate designs or structures that fall in a chain reaction when one tile is knocked over.
