"[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."

Great app Play it lots, on line and against the phone.

It cheats! The AI is used to roll the dice in favor of the CPU. I played many games at the expert level and the app got 'lucky' on EVERY roll. I'd be happy to conduct an analysis of THE BEST MOVE vs numbers rolled to show that the app cheats... On second thought I have better things to do.

Pass on this one Was good for several months. However, since the last couple of upgrades/downgrades, it is sooooo predictive. Pathetic!

Great AI works very well. It doesn't cheat, it's just statistically perfect so stop complaining when it appears to get lucky. The ai can maximize its roll potentials making it nearly impossible to win long matches. Undo doesn't work as expected when playing against ai.
