Gomoku (Omok)

Record vs AI

Black moves first; players take turns placing one stone.
The first to line up five stones horizontally, vertically or diagonally wins.
Free rule: no forbidden moves, and five or more in a row wins.
Renju: Black moves first and has an advantage, so only Black has forbidden moves. Black cannot play a point that makes a double three (two open threes), a double four, or an overline (six or more), and wins only with exactly five. White has no restrictions.
In Renju, forbidden points are marked with a red X on Black's turn. (This is a simplified check, so very complex shapes may differ from official rulings.)
