Take turns placing stones
The board has 15 × 15 intersections. Black moves first. Each player places a stone on an empty intersection; placed stones stay in position and are not captured.
Form a line
An unbroken line of five or more stones of the same color wins, horizontally, vertically, or diagonally. There must be no gap in the line.
Freestyle variant
This app uses freestyle Gomoku rules. It does not apply Renju restrictions, the Caro rule, or a win condition limited to exactly five stones.
End of the game
The game stops as soon as a winning line is formed. If the board is full and neither side has won, the game is a draw.
A situation to observe
Black has four consecutive stones on D8, E8, F8, and G8. C8 and H8 are empty. Playing H8 creates an unbroken line of five black stones.
