Overall a good design and game. TY ### 5/5 — My brother *2026-08-07, version 7.0.3* I love Joseph. ### 3/5 — Not a BAD AI backgammon game *2026-07-27, version 7.0.3* Well, it still cheats. Yes I have read the statistics, but I also got a set of physical dice and rolled the move for each player. With the manual tools, the win rate between the human and the AI is about 50/50. Without the manual rolls, AI wins all the time, having exactly the needed rolls at exactly the correct time. The interface is fabulous, the piece movement is great. You can’t blame the AI for wanting to win and having a way to make it occur! ### 5/5 — Not Random *2026-07-24, version 7.0.3* The rolls are not true. I play all the time with a board and other apps. ### 1/5 — The computer cheats *2026-07-22, version 7.0.3* I’ve put it to the test. It’s not random or coincidence. ### 1/5 — Cheats *2026-07-22, version 7.0.3* Regularly pulls high odd roles out of it’s pocket. ### 1/5 — Completely rigged *2026-07-17, version 7.0.3* Game is so rigged you can predict the rolls. Total joke. ### 4/5 — Great version *2026-07-15, version 7.0.3* Discovered recently you can look at future dice rolls for either player. Interesting but don’t use it. The one thing I’d LOVE is a tutorial mode. Telling me when there’s a better move - and maybe why. Even without it’s a great way to learn how to play. ### 2/5 — Cheats *2026-07-13, version 7.0.3* Very frustrating. I love the UI. I am an experienced backgammon player. The dice are not random. This app cheats. ### 5/5 — Been playing this a long time *2026-06-30, version 7.0.3* I am a very good backgammon player and have played ever since I was a kid. I started playing backgammon NJ several years ago and have I gotten play regularly on expert level. It has definitely improved my game over time and I have learned new strategies, some of which are almost counterintuitive. Specifically it has taught me to be more aggressive and take appropriate risks. Great game. ## Frequently asked questions about Backgammon NJ HD ### What is Backgammon NJ HD?
