AI difficulty
Easy focuses on nearby threats. Normal balances attack and defense; hard searches more candidate moves and deeper sequences. Every level checks immediate wins and the opponent's immediate winning threats first. Choose black, white or random to begin.
Hint · Game review
Hints suggest a point without playing it. Undo removes your previous move and the AI reply. Assisted games are recorded separately. Your latest ten completed games and preferences are stored in this browser.
Computer
The AI uses a Gomoku search algorithm in a separate browser worker. It does not call a paid language model for each move. Saved games can resume after refresh. Clearing this site's browser storage deletes those records.
