New OS/X Installations Available
There are new packages available for Mac OS/X (20110822 Snapshot)
Mountain Lion Users (10.8.x):
Download the DMG file, and read the README1ST file for information on
installing X11 on this platform. GNUBG will fail to run if X11 is not properly
Please read the README1ST file for installation requirements (X11), trouble shooting and miscellaneous help. If you experience random crashes in 3D mode on OS/X Lion 10.7, please see the README1ST file for a possible work around.
GNUBG must be installed to the /Applications folder.
If you need support for OS/X please contact Michael Petch at email@example.com
Building gnubg from source on Ubuntu
Here are some simple instructions to build gnubg straight from source on linux. The example is using Ubuntu 8.10, but the steps should be similar for any type of linux.
New Packages for GNU/Linux distributions
There are also new packages for GNU/Linux distributions available including 3d-support and some optimizations:
: built on OpenSuSE-10.1
: built on RedHat Advanced Server 4
The snapshots have been divided into two branches, a stable "rel_0_15" (rpms are built from these) and a current "MAIN" branch. The "MAIN" branch will be updated daily, the "rel_0_15" from time to time. Please note that "rel_0_15" doesn't contain any new features but only bugfixes.
Both tar.gz balls are available here

MS Windows distributions and exes
Two versions of GnuBG are currently available:
- current MAIN (CVS tag MAIN, current version 0.90): most recent source code (snapshot 20121023)
- Installation program (win threads, sse2)
- The installer will automatically detect if your CPU supports SSE2 and install the appropriate executables.To see if SSE2 exes have been installed, use the "Help/About gnubg" menu, "Build info" button: if "SSE.SSE2 supported" should be listed amongst the features, if your CPU supports it. To manuallly check if your PC supports SSE2, you can download and unzip this archve (TestSSE2) in any directory, then run the executable.
- Executables only archives:
- If your PC does not support SSE2 instruction set, use these:
- the old 0.15-stable (CVS tag rel_0_15): stable, but outdated. Use only in case of troubles with the most recent version.
Sources are available here.
Please reinstall fully if you have an installation older than 20121023, otherwise you can just download the exes and put them in the installation directory (you may want to rename them once unzipped).
Note: in case of problems with older MS Windows versions (i.e. 98, ME), you can try this older gnubg installation archive.
Building gnubg on MS Windows
Here's some instructions that allow you to build the latest version of gnubg on MS Windows. It is mainly aimed at people wanting to develop or test gnubg.
GNU Backgammon tutorial at GammonLife.com
Getting started with GNUBG, A guided tour.
Zorba (Robert-Jan Veldhuizen) has written a good tutorial for GNU Backgammon at GammonLife
. If you need an introduction to GNU Backgammon and how to analyse your games and matches, this introduction is great. Thanks Zorba.

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).
MS Windows commandline build with SSE support
Some are asking if there is a commandline version available for MS Windows with SSE support. Yes, now there is. Download here
. This build has not been tested much, so please report if there's something wrong. I believe it should work with Tony Lezards Dueller
