How to play
Reversi is a strategy game for 2 players on an 8×8 board. Each disc is black on one side and white on the other.
- Pick a mode. Computer, Online or 2 players.
- Trap and flip. Place a disc so that one or more of your opponent's discs lie in a straight line between it and another of your discs. The trapped discs flip to your color.
- Finish with more discs. When neither player can move, the game ends, and the player with more discs wins.
