Backgammon Guru holds a lot of promise but alas, has a lot of bugs. The analysis is pretty nice with its ability to reset a game to a certain point in time, point out good and bad moves, and allow you to resume from that point. The AI, a common weak point with other backgammon games, is pretty good. User interface is pretty weak, with 1980s era/Flash-port graphics. It can be hard to select a piece and dropping it on a point can require more precision than it should. But these are minor complaints compared to the quality of the AI. The bugs, though, make this game hard to live with. A new game can set up with a random piece somewhere on the board that is not really there (but will stay there for the game... distracting at best). Resuming a suspended game can result in the rolls being out of sequence (ie youre white and the dice roll is for white but the computer moves the black). And often, a crash takes you right out of the app. Probability of making it though a game? About 90%. I note this is version 1.0.1. Im looking forward to an update.
