Go Problems on the Internet

A list of collections of go problems that can be found on the Internet, sorted by language. A number of the sites listed below, particularly the Japanese sites, do not specify the character encoding in the HTML sent to the web browser. Therefore, you should modify your browser settings to auto-detect the character encoding. Some require Java.

Note On Selection: As of 2022, problem collections abound on the net, so only the selected ones should be added.

Note On Copyrights: In many jurisdictions, compilations are copyrightable, because collecting, selecting and arranging problems by their difficulty or themes are creative processes. Copying a whole published collection of problems may infringe rights of the compiler: check your local laws. See also Problem collections and copyright discussion.
