Your goal is to align three O pieces in a row, either horizontally or vertically. You win when three O pieces are connected in a straight line.
You win when three O pieces (including your player piece) form a straight line horizontally or vertically. The line must be three consecutive cells with no gaps.
You lose if three X pieces align in a row before you complete your winning line. Be careful not to accidentally push X pieces into a winning position!
Move your player with the arrow keys, WASD, or by swiping on a phone. Walk into an X or O piece to push it one square. You win when three O's stand together in a straight line, and your player counts as one of the O's. If three X's ever stand together in a line, the puzzle is lost.
