Gomoku: AI Challenge

Enter a quiet, modern game room built around one focused challenge: place five stones in a row before your opponent does. Play the strong on-device opponent anywhere, face a DeepSeek-powered cloud player when connected, or share one device for a two-player match.

Open the app for a quick round on a commute, practise a difficult position offline, or return to a saved match to study where the game changed.

Features:
• 15×15 freestyle Gomoku with black moving first
• One strong, varied offline opponent powered by local-v6
• Optional DeepSeek cloud matches with engine-guided move selection
• Pass-and-play for two people on one device
• Saved match records with step-by-step replay
• Undo up to 3 times per AI game; each undo rewinds your and the AI’s latest round. Without an active AI Pass, one rewarded ad unlocks all 3 undos; an active pass grants them directly. After an undo, eligible ranked games use the final valid game record; finished games cannot be undone.
• Local records and opt-in seasonal leaderboards for challenge score, wins, win rate, fastest wins, and streaks; choose a season and view past history
• Move preview, haptics, sound, reduced motion, and 12 interface languages

No social account is required. Match records remain on your device by default. Cloud play sends the board state and the anonymous session data needed to run the match. Joining public seasonal rankings is optional and is explained before any nickname or verified result is uploaded.
