War Galley is a game of naval warfare, which can be built and played using only matches.
Players create their galleys out of matchboxes, and give them orders using order matches. Movement and firing are done simultaneously after orders are revealed.
Enemy ships are attacked by dropping matches on the table, and hits are scored if a match points at the enemy vessel.
