Backgammon NJ for Android users say on Google Play
Still the only backgammon game on android worth playing. Admittedly hit my peak on the medium level, would be nice to have another level between that and hard to give me a chance... Excellent support, too.
Just such a good way to pass the time. I started out as a real beginner but now hold my own around 1600. I should really take advantage of all the features, including online playing. 4 years on. Still love this app. Only gripe is I wish it was easy - and I mean a click of a button easy - to replay the last game (or replay and switch sides). Keep up the good work!
probs the 2nd or 3rd best BG app after XG gammon. not a great UI, not nice colors offered. XG has better interface and engine. worse, is this app just gets ridiculous rolls all the time. when you play it all day every day.... you notice. no matter what the developer says about rolls. try it and you see and you'll be frustrated just like all of us. can't wait for XG to come back, which it is.
I have noticed, statistically, that around the time I start bearing off, my probability of rolling 1-2 or 1-1 goes to near 100%. Meanwhile, the computer's probability of rolling 1-2 or 1-1 plunges, as far as I can calculate (after hundreds of games). In addition, probabilities of rolling doubles seem to be very, very high for the computer early on in the game--when doubles are extremely advantageous. Yours, not so much. You will tire quickly of this insulting nonsense.
Doubles Delirium - Backgammon Edition! Outrageous. If you play long enough, you'll eventually witness the absurdities.
