About
The classic disc-flipping strategy game. Legal moves are dotted, flips animate, the last move is marked and passes are announced automatically. The CPU combines a positional weight table (corners good, squares next to corners bad) with mobility in an alpha-beta search one, two or three plies deep. Your best disc count against the CPU is saved.
Objective: Have more discs of your colour than your opponent when neither side can move.
Modes: vs CPU Easy, vs CPU Normal, vs CPU Hard, 2 Players
