All Threes Domino

Start by drawing 7 domino tiles each for a two-player game. Place the first tile on the board to begin the domino chain. Take turns placing tiles to either end of the chain, making sure that the matching numbers touch. Score points by creating 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. Continue playing until one player has no more of tiles or no more moves are possible. Whoever with the highest score at the end claims victory.
