Rules & objective
Two people share this screen. Black starts on a 15×15 board. Five or more stones in a horizontal, vertical or diagonal line wins. Overlines win; there are no forbidden moves. This table has no computer opponent or online matchmaking.
Hints inspect this board only: complete a five first, then block a direct opposing five, then consider local lines. They do not predict the full match or place a stone.
Controls
Take turns placing stones on empty intersections on the shared screen.
Worked example
Black and White alternate placing stones. Five or more horizontally, vertically or diagonally wins; this freestyle edition has no double-three or double-four restrictions.
