15×15 freestyle Gomoku against the computer: play black or white, black moves first. Wins, timing and the move record are judged deterministically by the program — the AI only decides moves, adds brief commentary and reviews the game afterwards.
Play 15×15 Gomoku against AI online in your browser. Choose Black to move first, or play White and let the AI open.
This is freestyle Gomoku with no forbidden-move rules; five or more stones in any direction wins. The rules engine validates moves, determines the result, tracks time, and keeps the move record, while the AI chooses moves and gives short reasons.
Follow each side’s move count and cumulative thinking time during the game. After the game ends, generate a review covering turning points, your attack and defense, and two suggestions for your next game.
