Click an edge between two dots to claim it. When you complete the fourth side of a square, the square is
filled with your initial and you get another turn. Chains of captures are claimed automatically.
Use the New button to start a new game with options (grid size, who starts, names, difficulty).
Play vs Computer toggles are available in the New Game dialog. Computer plays as the second player by default.
Smaller dots and a lighter grid make it easier to see claimed lines.
