GNU Backgammon Reaches 1.0 Milestone!
After 15 years GNU Backgammon has reached the 1.0 milestone and moved from a testing stage to official release. Thanks to Gary Wong and his vision to start this project, and everyone who has helped develop, maintain, and contribute through the years. Over time this product has seen its speed improve, and the neural network become stronger. Most Linux distributions are now moving GNU Backgammon 1.0 into testing and hopefully over the upcoming months will become more widely available thanks to our many downstream maintainers.
To mark this milestone GNU Backgammon 1.02.000 (July 28th, 2013) is being officially released for the Apple OS/X and MS Windows platforms.
- Download setup program for MS Windows 2000SP4 or later operating system with approximately 128MB of available RAM.
Apple Mac OS/X 10.5.x (and later) require the latest version of X11/Xquartz to already be installed to run properly. XQuartz can be downloaded from here. Please see the README1ST file inside the DMG for more installation information.

GNU Backgammon wins the 2006 Computer Olympics !!
I'm back from Torino where GnuBG has just won the 2006 Computer Olympics Backgammon "tournament", defeating its only opponent, BGBlitz by Frank Berger. Final score is 3-1 (best of 5 matches, 15pts each), with individual scores of 3-15, 16-12, 15-8 and 17-13.
Analysed matches (supremo, g11 met) can be downloaded here
For the records, BGBlitz is truly strong: it has been rated by gnubg analysis in the 4 matches as 1997.4, 2004.5 2035.1 and 2025.4 (FIBS rating) and in the first two matches, Frank used by mistake the "old" engine (winning one of them anyway).
One-sided race database reaches the midpoint
A one-sided race database that extends to the 13-point is now available for download. The file is a large one 1.6 GB, and may take close to a day to download even on broadband.
Other bearoff and hypergammon databases can be downloaded from here.
General information about using bearoff databases can be found here, including instructions for rolling your own.
Documentation wiki released
I'm happy to announce the release of the GNU Backgammon Documentation Wiki. Please visit the Wiki here
The documentation and user manual for GNU Backgammon is still a bit sparse. Hopefully things will improve. Meanwhile you can take a look at these links:
