If, as a result of movement, his fighter (or stack of fighters) encounters an enemy, a fight between the two top cards in each stack occurs, the result of which is decided primarily by the color (via a rock-paper-scissors mechanism) and secondarily by the number (highest wins). If the boss wins a fight, its power is reduced by the enemy's power for the remainder of the current fight; if two fighters draw, they both retreat one step toward their own village, possibly precipitating other fights on the same turn. The fight continues until either pile is depleted.
The first player to either defeat all of the opposing fighters or reach the end of the line (and clear out the opponent's fighters in his village) wins.
