Goal

Own the most discs when the board fills up or neither player can move. Black always moves first.

Placing a disc

• You may only place a disc where it traps one or more of your opponent’s discs in a straight line - horizontal, vertical, or diagonal - between the disc you place and another of your own.
• A move that traps nothing is illegal: if a square captures no discs you cannot play there.
• Placing a disc flips every opponent disc it traps to your colour, in every direction at once.

Passing

If you have no legal move, your turn is skipped automatically and your opponent plays again. You never choose to pass - the game passes for you and the board shows whose turn it is.

Winning & Draws

• The game ends when the board is full or neither player has a legal move.
• Whoever owns more discs wins; an equal split is a draw.
• Either player may offer a draw; the opponent can accept or decline.
