GNU Chess

GNU Chess is a program that plays the ancient board game, Chess. It is licensed under the GPLv2. The original version of GNU Chess, written by Stuart Cracraft, was one of the first major games to be developed deliberately as free software. On the game Free Software Foundation founder Richard M. Stallman said "We even developed a chess game, GNU Chess, because a complete [free] system needs games too." Version 6 of GNU Chess is based on Fruit, a chess engine by Fabien Letouzey

With Flatpak GNU Chess can be played by installing Sugarchess, a graphical front end made specifically for it. A contemporary version was included on the 100 Great Games for Linux shovelware collection.
