Combat Dominoes is a battle against the enemy's dominating dominoes in order to build a base and gain intelligence. Infantry and special-ops dominoes are used in the fight to defeat the enemy in the domino warfare action. Game play is similar to traditional domino games like All-Fives. The player with the highest double places it on the table facing horizontally. This becomes a separator that divides each player's base. On their turn, each player can place a domino only on their side of the divider, unless the other player runs out of viable plays, in which case their base becomes open to invasion by the opposing player. Dominoes with blank ends have unique special-ops graphics printed on them. When special-ops dominoes are played, one of several events can occur, such as swapping domino tiles with the opposing player, or engaging in domino "combat." The first player to shed all their dominoes wins the round. Points are tallied by adding up the number of pips from the dominoes still remaining in the loser's hand. The first player to accumulate 100 points wins the game.
