Gomoku Online
The classic five-in-a-row on a wooden board — against a sharp AI or a friend.
Renju Rules
Black must place exactly 5 in a row. Double-three, double-four, and overline are forbidden. White wins with 5 or more in a row.
01Connect five
Players take turns placing stones on the intersections. Black moves first. The first to line up five in a row — horizontally, vertically or diagonally — wins.
02Black's forbidden moves
Because Black moves first, Black may not make a double-three, a double-four, or an overline (six or more). Forbidden points are marked with ×.
03White plays free
White has no restrictions and also wins with an overline. Try to trap Black into forbidden points.
