Gomoku
Be the first to line up five stones on a 15×15 board.
How to play
Players alternately place a stone on an empty intersection. Black moves first. The first player to make an unbroken row of five or more stones, horizontally, vertically or diagonally, wins. If the board fills up, the game is drawn.
Gomoku with Swap2
Because moving first is a big advantage, this variant balances the opening, and exactly five in a row is needed (six or more does not win).
- Player 1 places two black stones and one white stone.
- Player 2 then chooses: play White; play Black; or place one more black and one more white stone and let Player 1 pick a colour.
- Play continues normally with White to move after the first option, or Black to move after the third.
