"[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,

"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.", May 2012
