How to play
- Place a black disc so that it traps white discs (horizontally, vertically, or diagonally) between two black discs, and every trapped white disc flips to black.
- You can only place a disc where it would flip at least one opposing disc.
- If you have no legal move, your turn is skipped automatically.
- When neither side has a legal move left, the game ends and whoever has more discs wins.
Where does Reversi come from?
Reversi is a classic board game first devised in Britain in the 1880s. It became a worldwide hit in the 1970s when a Japanese company commercialized the now-standard 8x8 version under the product name "Othello." The rules look simple, but the number of possible positions is enormous, which is why it's enjoyed by players of all ages.
Frequently Asked Questions
Do I move first?
Yes β you play black and move first, then alternate turns with the computer (white).
What if I don't see any highlighted squares to play?
You can't place a disc anywhere that wouldn't flip at least one opposing disc. If there's truly no legal move for your color, the turn passes to the computer automatically.
