Rules: you place a disc so that it traps a straight line of enemy discs between your new disc and another of your own discs. All trapped discs flip to your colour. You must flip at least one disc. If you cannot, you pass. The game ends when nobody can move, and the player with more discs wins. Corners can never be flipped, so they are very strong. The squares next to a corner are risky. Keys: Z undo, H hint, N new game.
