The player with the highest double (double 6 therefore) begins the domino game. If no one owns this domino, it will be the player with the strongest double. The next player in turn must place a domino having the same number of points on at least one side of the previously placed domino.
To win the game, you just have to be the first player to place all your dominoes. The game may be blocked. Then the player with the fewest points is declared the winner.
