How to play
Two people take turns on the same page, with Black playing first. On the 15ร15 board, connect at least five stones horizontally, vertically, or diagonally to win. These are freestyle rules without forbidden moves; overlines also win. A full board without a winner is a draw.
Select an intersection, then choose Place stone. On a phone, use the direction buttons to refine the selection. On a computer, you can also double-click a position, or use arrow keys followed by Enter or Space. Occupied intersections cannot be used again.
The latest move and winning line are highlighted. P or Escape pauses or resumes while the board is focused. Clicking outside or switching windows pauses automatically. Restart clears the board for a new round.
