Make five in a row on a 15×15 board against a four-level computer or a friend.
You (Black) to place a stone.
How to play
- Players take turns placing a stone on any empty point. Black goes first.
- Get five (or more) in an unbroken line — across, down or diagonally — to win.
- Easy builds its own lines and often misses yours. Hard always blocks your strongest line. Extreme checks your best reply to each of its moves. Nightmare searches several moves ahead for up to about 0.6 s.
