What Gomoku Can Do
This Gomoku game delivers authentic five-in-a-row gameplay with modern conveniences. You choose your difficulty level, and the AI adapts its strategy accordingly.
Game features:
- 5 difficulty levels (Beginner through Expert) to match your skill
- Real-time board display showing all pieces and legal moves
- Win detection across horizontal, vertical, and diagonal lines
- Instant move validation with visual feedback
- Move history tracking so you can review your strategy

Step-by-Step Guide
- Choose your difficulty: Select a level from Beginner (if you're learning) to Expert (if you know Gomoku strategy).
- Make your first move: Click any square on the 15x15 board. You play as the first player (traditionally black stones).
- Watch the AI respond: The computer evaluates the board and places its stone. Higher difficulties require more calculation time.
- Build your five: Place stones to create a line of five while blocking the opponent's lines.
- Win or learn: Get five in a row to win, or lose to understand where your strategy needs improvement.
Use Cases
Board game enthusiasts learning Gomoku: Beginners start on Easy difficulty to learn legal moves and basic tactics. After 10-20 games, they understand opening positions and advance to Normal difficulty.
Casual gamers looking for quick strategy sessions: Gomoku games average 5-15 minutes, making it perfect for breaks between work. No account setup means you go from clicking the site to playing in seconds.
Competitive players training against AI: Advanced players use Expert difficulty to refine their middle-game tactics and endgame calculations. Playing dozens of games against consistent AI helps identify weaknesses faster than human opponents.
Students exploring game theory: Computer science and mathematics students analyze how the Gomoku AI evaluates positions, then compare strategies across different difficulty levels.

FAQ
What happens if neither player makes five in a row?
On a 15x15 board, if the board fills completely without anyone getting five in a row, the game ends in a draw. This is rare on Easy difficulty but possible on Expert when both players defend perfectly. Some Gomoku variants use larger boards (19x19) to reduce draws.
Can the AI ever lose on Expert difficulty?
Yes. The Expert AI plays near-optimally but isn't unbeatable. It can make rare miscalculations when multiple threats exist simultaneously. Beating it requires understanding opening theory and recognizing when you've created an unstoppable advantage.
Is Gomoku the same as Five in a Row?
Gomoku (meaning "five stones" in Japanese) and Five in a Row are the same game. Some countries call it Pente. Rules vary slightly (some versions restrict the first move to center), but this Gomoku implementation uses the standard rules played internationally.
