REVIEWS
(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, 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."

    Really nice to play. I don't understand why anyone thinks the dice are fixed. Turn on hint mode for a bit and see where you're going wrong. It's really improved my game. Changed comment: Please add a difficulty level between hard and expert.

    I've been playing Backgammon NJ for years, on Android and IOS. It's smart and has helped me to up my game. But despite the developer's incessant "Proof here" diatribe I'm still able to predict what the computer is about to roll far far too often. I thought I would try a little experiment. I tried to play as poorly as is humanly possible, and force the computer to backgammon me over and over. It's

    Best backgammon app available. Playing against the computer is very challenging and will help improve your game.

    I have watched it auto finish games and it will give itself free doubles when there is zero chance of the other player winning. I have played most of the good backgammon programs on pc and android and this cannot complete with the better pc programs but it will dust the other phone programs. And the developer apparently does not actually read these reviews as he responds same way regardless of

    This game does a lot of things good. But it's still up to you to use all the features. The number one best thing NO CRY BABY'S!!.The games rolls are fair but you need to read the instructions not just play to see this.If your looking to up your game this BG game is for you.
