How to play
- Start at the center. The board opens with four discs. Black moves first.
- Bracket an opponent. Place a disc that traps at least one opposing disc between your new disc and another of your discs.
- Flip every line. All bracketed horizontal, vertical, and diagonal lines turn your color.
- Pass when blocked. If you have no legal placement, play passes automatically.
- Count the discs. When neither player can move, the player with more discs wins. Equal counts are a draw.
