The classic board game is here, in your browser!
Reversi (or Othello) is a strategy board game for two players. You play on an 8×8 uncheckered board.
There are sixty-four identical game pieces called disks, which are light on one side and dark on the other. Players take turns placing disks on the board with their assigned color facing up. During a play, any disks of the opponent's color that are in a straight line and bounded by the disk just placed and another disk of the current player's color are turned over to the current player's color.
The object of the game is to have the majority of disks turned to display your color when the last playable empty square is filled.
The rules sounds a little bit difficult but if you like strategy board games where you need to think you'll love this one.
