(Reviews for iOS version)

"[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,

"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."

    Others have said this game manipulates the dice rolls, but I disagree. I think the dice rolls are random, but the app generates the sequence ahead of time, and knowing what is coming influences its moves.

    This is absolutely the best, most professional backgammon app in the playstore, and the new analysis feature is an invaluable tool for improving your game. Toughest ai, too, from what I can tell. So far I've had good experiences playing online as well.
