All Threes Domino

Launch by picking 7 domino tiles each for a two-player game. Set the first tile on the board to begin the domino chain. Take turns attaching tiles to either end of the chain, making sure that the corresponding numbers connect. Score points by forming multiples of 3 at the ends of the chain. Figure out your score by totaling the numbers on the ends of the domino chain after each move. Proceed playing until one player has no more of tiles or no more moves are possible. The one with the highest score at the end claims victory.
