About Reversi
Reversi — the same game sold as Othello — takes about ten seconds to learn and a lifetime to stop losing. You place a disc so that it flanks a line of your opponent's discs between the one you just dropped and another of your own, and every disc caught in that line flips to your colour, in any direction at once. The catch that makes it deep: you may only play a move that flips at least one disc, so your options are constantly dictated by the shape on the board. Beginners grab discs greedily and get crushed; the counter-intuitive truth is that holding fewer discs mid-game keeps your mobility high, and the corners — which can never be flipped once taken — are worth more than any pile of pieces. A single late move can flip an entire row and swing the majority, so nothing is settled until neither side can move. Play free in your browser against an easy or hard computer, with your wins saved between sessions.
How to play
- Place a disc so it traps a line of the computer’s discs between your new disc and another of yours.
- Every trapped disc in that line flips to your colour — in any direction, including diagonals.
- You can only play a move that flips at least one disc. If you have no move, your turn passes.
- When neither side can move, whoever owns more discs wins.
Strategy & tips
- Grab the corners — they can never be flipped, so they anchor your position.
- Avoid the squares next to a corner early; they often hand the corner to your opponent.
- Do not flip too many discs early; keeping fewer discs (mobility) mid-game is often stronger.
- Aim to control edges, which are hard for the opponent to flip.
- Late game, count carefully — a single move can flip a whole row and swing the majority.
FAQ
Is Reversi the same as Othello?
Yes. Reversi and Othello are the same disc-flipping strategy game on an 8x8 board.
How do I win?
Own the most discs when neither player can make a legal move. Trapping and flipping lines is how you take the lead.
Why did my turn get skipped?
If you have no legal move that flips at least one disc, your turn is skipped automatically and play passes back to the computer.
