About the game
Reversi Duel is classic Othello against a computer rival with three strengths. You play black. Place a disc so that a straight line of white discs is trapped between your new disc and another black one, in any of eight directions, and every trapped disc flips to your colour. Dots show every legal move, and if you have none you pass. When the board is full or nobody can move, the bigger colour wins.
For a twist, switch the board to Shifting Rocks. Four rocks, one in each quarter of the board, block their cells, and every ten moves they jump to new empty spots. A corner that was safe can suddenly open up, or an edge you planned on can be cut off, so plans need to bend.
