Place your domino tiles on the playing surface to initiate the game. Match the numbers on your tile with those on the board. If you don't make a match, draw a tile from the pile. The aim is to play all your tiles before your competitor does. Block your opponent by carefully choosing where to put your tiles to limit their options. The game finishes when one player exhausts their supply of tiles or when no more moves are possible. The player with the lowest number of tiles left wins.
