About Reversi (Othello)
Reversi — also known as Othello — is the classic disc-flipping strategy game on an 8×8 board. You play the dark discs against the computer’s light discs. On each turn you place a disc so that one or more straight lines of the opponent’s discs are trapped between your new disc and another of yours; every trapped disc flips to your colour. If you can’t make a legal move you pass. When neither side can move the game ends, and whoever has the most discs on the board wins. Pick a difficulty to choose how cleverly the computer plays — from random moves to a corner-and-edge-weighted look-ahead. It all runs in your browser. No signup, no download.
Frequently asked questions
You play the dark discs. On your turn, place a disc so it traps one or more straight lines of the computer’s discs between your new disc and another of your discs. Every trapped disc flips to your colour. The board highlights your legal moves; if you have none, you pass.
They are essentially the same game on an 8×8 board with the same flipping rules. Othello is the trademarked version and fixes the standard four-disc starting position in the centre, which this game uses.
The game ends when neither player can make a legal move — usually when the board is full. Whoever has more discs of their colour on the board at that point wins. It’s a draw if both have 32.
If you have no legal move you pass and the computer goes again. If neither side can move, the game is over. The board only lets you click squares that are actually legal.
It depends on the difficulty. Easy plays a random legal move, Normal grabs corners and the move that flips the most discs, and Hard looks a few moves ahead using corner and edge weighting — corners are the strongest squares because they can never be flipped.
