Finish with more discs of your colour than your opponent.
- Place a disc so that it traps a straight line of opposing discs between it and another of yours. Every trapped disc flips to your colour.
- Marked squares are your legal moves. With none, your turn passes automatically.
- Corners can never be flipped back, so they are worth having.
- The game ends when neither side can move.
