Domino Keepers Addition a game for 2 players (or two teams) All of the dominoes are placed in the centre face down. Both players pick up a domino at the same time. Each player tells the sum of the dots on their domino, e.g. 2+4=6, 5+3=8. The player with the highest answer keeps both dominoes. If both players have the same answer, each keeps a domino. The winner is the player or team with the most dominoes when all dominoes have been picked up.
