The document summarizes the rules of the classic domino game: - Domino is played with rectangular tiles divided into two squares numbered 0-6, with a full set containing 28 pieces. Variations use tiles numbered 0-9. - The game is usually played by 4 players in pairs who take turns placing tiles so that adjacent squares match. The aim is to use all tiles on one's turn. - The game ends when one player uses all their tiles or a block occurs where no more tiles can be placed, at which point scores are totaled to determine the winner.
