How to play

Place a disc so it traps a straight line of your opponent's discs between it and one of yours.
Every trapped disc flips to your colour, in all eight directions at once.
No move that flips? You pass. When neither side can move, most discs wins.
Tips: corners can never be flipped back, so avoid the squares right next to an empty corner. Early on, fewer discs and more choices beat a big pile.
