A magnetic duel for 2 players by Susumu Kawasaki.
In GAUSS, each player has a set of fifteen discs: ten in their color and five in the opposite color. Player take turns placing a disc on the board. Like the poles of a magnet, discs of opposite color are attracted to each other whereas discs of the same color are repelled. Each time 4 or more discs of your color get connected you score points. The player with the highest score at the end of the game wins.
