Two players, Black first, on a 9×9 board. Connected groups without liberties are captured. Suicide and repetition of any earlier complete board position are forbidden (positional superko; passes are exempt). Two consecutive passes start scoring. Either player may mark whole dead groups; every change resets both confirmations. Chinese-style area counts living stones plus surrounded empty points, with 7.5 komi for White. Both must confirm to finish. Dead groups are never guessed automatically: resume the unchanged position and play out a disagreement. These are stated casual rules, without tournament adjudication or special ko procedures. Resigning is allowed.

Rooms expire 24 hours after the last action. Refresh to reconnect; leaving ends the current game.
