FAQ
Which computers does it run on?
macOS on Apple Silicon and Windows x64. There is no Intel Mac build. On Windows it needs the WebView2 runtime, which Windows 10 and 11 usually include.
Will my games still be there after upgrading to 3.x?
Yes. Versions 3.0 and 3.1 keep the storage format of 2.x, which kept the format of 1.x, so saved games, the game library, results, practice progress, and settings open as before. The Think setting from 1.x (fast, standard, deep) is gone, and a saved value for it is ignored.
What happens when I import an SGF?
It opens at the last move; the timeline under the board steps through it. If the game is unfinished, press Continue to play on, against the computer too. Import and Paste are at the bottom of Games in the ⋯ menu, or drag a .sgf file onto the window; Export is on the review card.
How strong is the computer?
All four levels use one engine. Beginner blocks your fours but often misses open threes; Normal thinks for 0.55 seconds a move, Hard for up to about 2 seconds, and Extreme runs Hard's search for the full 5 seconds. The computer always waits at least 0.6 seconds before it plays. Under Renju, its search leaves out the points where Black may not play. By default you alternate colours on Hard and Extreme. The rule set is chosen on the New game card and applies when you press Start.
