A minute to learn, a lifetime to master
Reversi is played on an 8×8 board with discs that are black on one side and white on the other. On your turn, place a disc so that one or more of your opponent’s discs are trapped in a straight line – across, down or diagonally – between your new disc and another of yours. All trapped discs flip to your colour. If you cannot flip anything, you must pass. When neither player can move, the one with more discs wins.
Play against the computer on five levels – level 1 plays randomly, level 5 looks several moves ahead and plays the endgame perfectly – or with a friend on the same screen. Legal moves are shown as dots, and you can turn them off for a harder game.
How to use
- Choose the computer (and a level) or two players. Black moves first.
- Tap a square with a dot to place your disc – trapped discs flip automatically.
- If you have no legal move, your turn is skipped.
- The game ends when no one can move; most discs wins.
Ideas for using it
- Corners. corner discs can never be flipped – they are the most valuable squares.
- Avoid X-squares. the squares diagonally next to corners often give the corner away.
- Mobility. having more possible moves than your opponent is often better than having more discs.
- Kids. level 1 and the move dots make it easy to learn.
