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

Customer Reviews

Great to practice

At its highest level the GnuBG program makes some different moves - even in the openings - than this AI; but on the whole this is a very good program, a great opponent when there is no human around,and very hard to beat consistently. Haven't tried the game center functionality but I bet it is slick like the rest of the game.

Anyone who complains about the dice rolls should take a look at the list of dice rolls that the app will generate for you ahead of the game. It doesn't "make up what it needs" - it will tell you ahead of time what it will roll (menu-> next 100 rolls). You can write those down so you know what the computer will roll next. If you need that help.

On long plane rides I really enjoy playing this game. It is slick and well done.

Horrible!!!!

Try this-play against the computer on "expert". You will never be so frustrated in your entire life. The computer most always will get every magical role it needs. It's supposed to "teach" proper playing, but instead seems to have the unfortunate programming to be set to win at all costs even at the expense of teaching. Wait until you roll the dice 8 times without the one number you need....fun time! The computer needs a 6 & 3 to really mess you up? Guess what?!...the computer gets a 6&3!! It's just plain silly how poorly its programmed. See how many times you get double sixes when the six space is blocked. See how many times you or your opponent get doubles on your last roll. When it is so blatantly obvious it can't be denied. Save yourself the aggravation and get a different app really interested in fair and and teaching you how to become a better player

Why the AI wins!! What you need to know!

Let's get right to it. While the dice rolls against the AI are randomly generated, it is not "fair" because the AI can now "look ahead" and make moves based on what it already knows you are going to roll! Sadly, this is not the "best" learning tool because the AI will leave blots or make seemingly bad moves since it already knows what's going to happen. If you copy down the randomly generated rolls and then replay the game manually your winning percentage will increase. So...why four stars? Because YOU can look ahead too and make it a bit fairer. It's also a pretty good AI when you play in manual mode but it does "cheat" so deduct one star. It's lots of fun if you don't take it too seriously!
