About Gomoku
Place black stones on an 11×11 board and make five in a row before the white heuristic AI. The board is fixed at 11×11 and the human always plays Black first.
Win detection checks horizontal, vertical and both diagonal directions for a connected count of at least five. The AI evaluates every empty cell using its own pattern score plus 0.9×the player's pattern score and a small center bonus.
How to Play Gomoku
1Click an empty intersection to place a black stone.
2Watch both your own potential five-in-a-row and the white AI's developing lines.
3Create a horizontal, vertical or diagonal line of at least five black stones first.
Gomoku Rules
- Occupied cells cannot receive another stone.
- Five or more connected stones in any checked line direction wins immediately.
- The source has no explicit full-board draw handler, so this page does not claim automatic draw resolution.
