REVIEWS

"[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 & friends." -Phil Simborg, Professional Backgammon Teacher & 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 & has more useful functions than any other backgammon apps out there."

"For serious backgammon players, Backgammon NJ is the way to go." -Macworld.com, May 2012

Relatively accurate

The levels are all or nothing. Easy is too easy and hard is too hard. It would be more realistic if the proportion of hard rolls were intermittent but increasingly prevalent as the levels got harder. Similarly the fortuitous rolls could be intermittent with the majority of rolls random. Maybe that's what the designers were aiming for but the hard levels are so persistently punishing that it's not worth attempting them. I am a very reasonable when I lose but those hard levels are ridiculous. I love playing on this app but there needs to be a smaller step above medium level.

Excellent

Have been playing this game for some time and more recently the online version via iPad. Online seems slow at times but it is fun to play others and try and improve ones rating. Offline is very good. Dice seem generally good and we could argue all day about it, it does seem to throw better dice for the computer side on the hard rating. Overall though very pleased.

These dice are loaded..

I have been playing long enough to know that one player cannot have that much luck, the dice rolls should be random but this game is obviously designed to frustrate the player into playing game after game when there is little chance to win. I will be deleting this game.

Developer Response ,

The app is honest & has random rolls. Proofs here: http://www.njsoftware.com/note.html
