Impossible
I have played a lot of online backgammon and Ive never seen dice cooperate with an opponent as much as Ive seen with this app. The makers explanation of how it uses advanced algorithms to bring about random dice just doesnt jibe with the incredible ability of the computer opponent to get the perfect rolls when it needs them. I will be looking for another backgammon app.
My only explanation for this app is it must have been created by Apple to get people to smash their IPhones in frustration .
