Quantum is an abstract strategy game, played on a simple squared board, with three different types of pieces. A quick game may be played on the central 60 squares of the board, or the full game on the entire 96 squares.
Initially, all pieces move just one square. A square piece moves horizontally and vertically, a circle moves diagonally and a cross combines the two moves. Opposing pieces are captured by landing on top of them to form towers. A tower may move as many squares as pieces it contains. "Power" squares in each corner allow unrestricted movement. Once a tower reaches the height of six pieces, it can no longer move or be captured. The game is won when black or white owns three towers of 6 pieces.
Both offensive and defensive strategies are possible and players should remember that a tower of 6 cannot move or be captured, but it can still block!
