Set your domino tiles on the playing surface to begin the game. Match the numbers on your tile with those on the playing surface. If you can't make a match, take a tile from the boneyard. The aim is to lay down all your tiles before your opponent does. Stop your opponent by carefully choosing where to put your tiles to limit their moves. The game ends when one player exhausts their supply of tiles or when no more actions are possible. The player with the least tiles left claims victory.
