The GNUbik program is an interactive, graphical, single player puzzle. Yes, this is another implementation of the classic game like that invented by Erno Rubik. You have to manipulate the cube using the mouse. When each face shows only one colour, the game is solved.
GNU Gnubik is written in C and Guile. The latter allows you to extend the program using the Scheme language — a simple programming tool which even novice computer users can use. For example, you can use Scheme to write your own automated solving routines or to create patterns.
Gnubik is a graphical program. Look at some screenshots to see how it looks in action.
Some features of Gnubik include:
Gnubik can be found on the main GNU ftp server: http://ftp.gnu.org/gnu/gnubik/ (via HTTP) and ftp://ftp.gnu.org/gnu/gnubik/ (via FTP). It can also be found on the GNU mirrors; please use a mirror if possible.
Using the program is very intuitive — You just point and click! Documentation therefore is somewhat redundant. However a manual is available online. You may also find more information about Gnubik by running info gnubik or man gnubik, or by looking at /usr/doc/gnubik/, /usr/local/doc/gnubik/, or similar directories on your system. A brief summary is available by running gnubik --help.
