How to Play Reversi
- You play Black; the AI plays White. The board starts with two black and two white discs in the center.
- Click any highlighted square to place a disc. You must flip at least one of the opponent's discs.
- Discs are flipped in every direction where your new disc sandwiches a line of opponent discs.
- If you have no valid move your turn is skipped. The game ends when neither player can move.
- The player with the most discs at the end wins.
Tips & Strategy
- Corners can never be flipped — capture them whenever possible.
- Avoid placing next to a corner before you own it; it gives your opponent an easy grab.
- Fewer discs mid-game is often better — maximising your mobility matters more than disc count.
