About the game

Reversi Classic is the disc-flipping board game, played in 3D. You and your opponent take turns placing one disc. A move only works where it traps at least one enemy disc in a straight or diagonal line between your new disc and one of yours, and every trapped disc flips to your color.

Dots show where you can go. Corners can never be flipped back, so grab them early. If you have no legal move, your turn passes, and the game ends when nobody can move. Whoever holds more discs then wins.
