Analysis Software (Desktop)
eXtreme Gammon (XG) — The Gold Standard
Platform: Windows | Price: Paid ($99+)
eXtreme Gammon, known universally as “XG,” is the most powerful backgammon analysis tool ever created. It plays at a level that no human can match and provides move-by-move game analysis that serious players use to identify and eliminate errors.
Key features:
- Neural-network engine at superhuman playing strength
- Full game import and analysis (shows every error with severity rating)
- Rollout analysis to determine true equity of any position
- Match equity tables built in
- Cube decision analysis
- Extensive database of positions and matches
Who it’s for: Intermediate to advanced players who want to improve seriously. The analysis feedback is extremely detailed and requires some backgammon knowledge to interpret.
Why it matters: The strongest human players benchmark themselves against XG. A “0 errors” game versus XG is essentially a perfect game by any human standard.
GNU Backgammon — Free and Excellent
Platform: Windows, Mac, Linux | Price: Free (open source)
GNU Backgammon (gnubg) is the best free alternative to XG. It uses a neural-network engine that plays at a very strong level — stronger than any human, though slightly below XG’s ceiling.
Key features:
- Free and open source
- Solid neural-network engine (plays at approximately expert level)
- Game import and analysis
- Rollout capability
- Available on all major platforms
Who it’s for: Players who want powerful analysis without paying. GNU is good enough for the vast majority of players to find and fix major errors.
Limitation: Less polished interface than XG; analysis is slightly less accurate at the highest level; no active development of new features.

How to Use Analysis Software Effectively
Simply playing is not enough to improve. Here’s how to get maximum value from analysis tools:
- Play a game (against strong AI or a real opponent)
- Import the game into XG or GNU Backgammon
- Review the analysis — focus on moves marked as blunders (red) or errors (orange)
- Understand why each highlighted move was wrong — don’t just see the correct move, understand the reasoning
- Look for patterns in your errors — do you consistently misjudge race positions? Cube decisions? Hitting choices?
- Review after every session, not just occasionally
Players who review games improve 5–10× faster than those who only play.
Frequently Asked Questions
What is the best free backgammon software?
GNU Backgammon is the best free analysis software — it plays at expert level and analyzes games in detail. For online play, FIBS is free and has a large community. Backgammon Galaxy has a generous free tier with strong features.
How does eXtreme Gammon (XG) work?
XG uses a neural network trained on millions of backgammon positions to evaluate every possible move. It calculates the expected outcome of each move through rollouts (simulating thousands of games from a given position) and recommends the highest-equity option. Top players import their games into XG for move-by-move error analysis.
Can I play backgammon on my phone?
Yes. Backgammon NJ, VIP Backgammon, and Backgammon — Lord of the Board are all available on iOS and Android with strong AI and/or multiplayer. You can also play BackgammonHit.com in your mobile browser for free without downloading anything.
Is there a backgammon app with a strong computer opponent?
Yes. eXtreme Gammon (XG) has the strongest AI. For mobile, Backgammon NJ and GNU Backgammon (mobile version) offer the strongest AI opponents. The top difficulty settings in these apps are competitive even for intermediate-level human players.
What software do professional backgammon players use?
Professional players universally use eXtreme Gammon (XG) for game analysis. They play competitively on platforms like Backgammon Galaxy, FIBS, and in person at tournaments. Many also use rollout tools and reference position databases to study specific situations.
Is online backgammon rigged?
Reputable platforms (Backgammon Galaxy, FIBS) use certified random number generators for dice. The random results can feel “rigged” because humans are poor at intuitively understanding truly random sequences — we expect balanced distribution within short runs, but truly random dice don’t guarantee that. Play enough games and the distribution normalizes.
