Weiqi
Play 9x9 Weiqi in the browser against easy, normal, and hard AI, with normal already applying real pressure and hard being difficult to beat.
Board
This is a 9x9 Go board. You play black and move first; the game scores after both sides pass in a row.
How It Works
Difficulty & Levels
Normal starts caring about shape, sente, and territory efficiency. Without some practice, most players will not beat it easily.
Board Info
The endgame uses territory estimation with 5.5 komi for white. Current captures and estimated area stay visible on the right.

Controls
Captures, suicide prevention, and simple superko are supported. Two consecutive passes end the game automatically.
If you surround an entire enemy group and remove all of its liberties, that full group is captured automatically.
When the board is mostly settled, you can pass. Two consecutive passes trigger final scoring.
Normal values connection points, cutting points, and territory borders more seriously instead of diving at every nearby capture.
Hard runs more local simulations and punishes thin groups more reliably, so fights on the 9x9 board get sharper.
