The players take turns to "fire" "photons" (pieces of their color) into a 7 7 grid from any edge. A fired photon travels in a straight line until it reaches the opposite edge or another photon: then it stops, and any adjacent photons change color to match it. The winner is the player who has more photons of their color on the board when no more moves can be made.
