A two-player placement game.
 
The board is surrounded by arrows which denote the direction in which Photons may be fired.
 
The player places a Photon atop one of these arrows and the Photon then fires across the board until it either encounters the opposite edge of the board or another Photon of either color. Where they change any adjacent enemy Photons and all that are directly adjacent in an orthogonal line, each into one of its own color.
 
In order to place a Photon on the board there must be a clear path from one of the arrows which surround the field.
 
A player wins by having the most Photons on the board at the end of the game.
