Reversi is a minute to learn and a lifetime to master. Place a disc so that it traps a line of your opponent's discs between it and one of yours, across, down or diagonally, and every trapped disc turns over to your colour. Corners can never be taken back, edges are precious, and the board can swing on a single move. Play the computer at Easy, Medium or Hard: it looks a fixed number of moves ahead at each level, so everyone faces the same opponent. Each level has its own Plocky leaderboard for the biggest win, with the faster time breaking ties. Or play a friend on one screen. Legal moves are marked for you, and taking a move back is always allowed; it just makes the game practice.
