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

This game is best for people:

NOTES

1) Stats for online matches against live opponents are not available during the match because stats can help one play better than his actual skill level. After the match ends: view stats, export match file, & analyze in GnuBG.

Stats for offline matches are available at all times because there are no live opponents.

2) If an online match ends for any reason, you'll receive the Elo points you deserve. FAQ: http://gamecenter.njsoftware.com
