Gomoku - AI & Friends

One move can change the game.
Practice against AI or challenge a friend on a 15×15 Gomoku board. Start playing without creating an account.

CHALLENGE FOUR AI LEVELS
Choose Beginner, Intermediate, Advanced, or Master. Learn the basics at your own pace, then take on a tougher opponent. AI matches work offline, so you can play without an internet connection.
Choose black, white, or a random stone color before you begin.

PLAY WITH FRIENDS ON ONE OR TWO DEVICES
Take turns on the same device for a face-to-face match.
Or connect two nearby Android devices and play on your own screens without the internet. For nearby play, install the app on both devices, enable Wi-Fi and Bluetooth, and allow the required connection permissions.

SAVE YOUR PROGRESS AND REPLAY YOUR GAMES
Resume unfinished AI matches and same-device games from where you left off.
Check results and move counts in your match history. Replay saved games one move at a time or adjust the playback speed to revisit the moments that decided the match.

PLAY WITH FORBIDDEN-MOVE RULES
Black cannot play double-threes, double-fours, or overlines. Black wins with exactly five stones in a row; White wins with five or more. Lines can be horizontal, vertical, or diagonal. The app prevents forbidden moves and shows an explanation on the board.

MAKE EACH MATCH YOUR OWN
• Undo moves in AI and same-device matches.
• See the last move highlighted on the board.
• Adjust stone sounds, vibration, and the keep-screen-on setting.
• Switch between English, Japanese, and Korean.

Settle in for a quick game or take your time reading the board. Your next move is waiting.
