Gomoku AI: Play Five in a Row

Play Gomoku, the classic five-in-a-row board game, against the AI or a friend. Connect five stones on a 15×15 board and practice your opening, attack, and defense. THREE WAYS TO PLAY • Play the AI: choose black or white and test your tactics. • Two players, one device: take turns on the same board. • Nearby multiplayer: host or join a LAN room and play on separate devices. FOLLOW EVERY MOVE Move numbers, a last-move marker, and winning-line highlights keep the position clear. Undo moves in AI and same-device matches to rethink your next move. Black forbidden-move detection includes overlines, double-threes, and double-fours. PICK UP AND PLAY No account required. AI and same-device matches work offline; nearby multiplayer requires local network access. Play on iPhone or iPad in portrait or landscape, with English, Simplified Chinese, and Traditional Chinese interfaces. Fit in a quick practice match or settle in for a thoughtful game with a friend. Your next move is waiting.
