FAQ

Does or will Goban work with the Kiseido Go Server (KGS)?
KGS uses a closed protocol and wants to control both the server and client. They are actively discouraging 3rd party clients. Goban will not work with KGS as long as this is the case.

Does or will Goban run on Mac OS 9, 8, ... ?
Sorry, no. Goban is a Mac OS X only application. Go software for older Mac OS releases is listed on the Shodan web site.

Does or will Goban run on Windows?
Sorry, no. Goban is a Mac OS X only application. We currently have no plans to do a Windows version.

Does or will Goban run on Linux?
Maybe. Goban is currently a Mac OS X only application. We could port it to Linux when GNUstep is sufficiently advanced.

How strong is the program?
GNU Go plays regularly on the NNGS and KGS go servers and its ratings graphed over time are available: NNGS [currently unavailable], KGS. Several GNU Go robots are also playing regularly on the IGS (with a rank of 12 kyu).
