"[I] know strong bg play when I see it. This app is the strongest iPhone bg app I've played with by far. It does not cheat period. ...Analyzing these matches with eXtreme Gammon confirms a world class level of play with normal luck factors. If you are losing, get over it. So would 99.9% of the other backgammon players in the world. It is just that good. Learn from it." -Richard Munitz, Giant of Backgammon, #21 world ranking in 2009

"Backgammon NJ plays at an extremely high level with an excellent interface, and I often use it to practice on my iPhone when I am traveling. I recommend it highly to my students and friends." -Phil Simborg, Professional Backgammon Teacher and Player, www.mindgamescenter.com

"I've played over 500 games now; I've checked about 5% of these against World Class Desktop programs (GNU, BGBlitz); and I've actually used some of the competition. NJ has the best interface and has more useful functions than any other backgammon apps out there."

"As someone who has played a lot online (FIBS, Gamesgrid, and others) and live, playing this app (on its hardest setting) is like playing a master player or like playing GNU."

Best bg app Best backgammon app available. Greatly improves your game and fun to play. I bought extreme gammon for my iPad and it pales in comparison - particularly in the areas of graphics and unobtrusive tips. It would be nice to be able to hide pip count with option to view it at "match info" or "hint."

Yawn You will quickly tire of the ai always getting perfect rolls and more doubles, lots more. Oh, stats will show about equal doubles but you'll get yours when they don't really count. And when you have a piece on the bar and two points to enter you will roll 5, 6, 7 times without rolling one of those two numbers. This is not unusual. All together just terrible.

Really top game. At higher level it is hard to beat! Best backgammon program I have found. It can play an incredible back game which I love to compete against! April 2014.....however I wonder why my opening throw is so often 6 & 3. At least 1 in every 3 games. Also when bearing off the computer gets more than its fair share of double 6s.

Much better than what I used before While there is an issue with the frequency of double dice for both AI and human, this app seems to have fairer AI than the app I used before. Note that you can use manual dice here if you so choose. The higher skill level actually seems like a better player as opposed to relying on the extremely fortunate dice rolls that are the hallmark of many other apps. I wish one could customize the look of the board, but this is minor. Bottom line, this is worth paying for.
