Each player starts with 25 "ovni's" in his own color, 4 blue "ovni's" and 1 white "ovni". The players take turns placing "ovni's", which are gears, on the board, thus creating a chain of gears. The gears must placed so that the gears can still turn. A player can block an opponent's chain by placing a pirate (blue "ovni") at the end of his chain. The player that can make the opponent's gear turn wins.
