Our Expert Score

94/100

Backgammon NJ is frequently cited by enthusiasts as the gold standard for mobile Backgammon. The reason is simple: the AI. It uses neural networks to play at a world-class level, providing a challenge that is genuinely fair. Many people complain about 'rigged dice' in card and board games, but Backgammon NJ allows you to verify the dice rolls using a manual seed, proving its integrity.

The UI is clean and efficient, focusing on the board and the moves rather than flashy effects. For those looking to improve, the 'Hint' and 'Tutor' features are powered by the same top-tier engine, showing you the mathematical probability behind every move. It’s more than a game; it's a professional-grade training tool for one of the world's oldest strategy games.

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
