Apparently, after having played a lot of games, I can tell that, when a double is accepted by me, the computer gets so much doubles that it is impossible to win. Also, when hits are possible, the computer takes it all. Great app, but chances aren’t shared equally

Without a doubt, the worst backgammon app I have come across. The game has always been one of both luck and tactics, I.e. the luck of the draw, or the throw of the dice. That has all been taken away. As an example. If I need to throw a 3 to get back onto the board, if all other slots are taken by the opposition, I can guarantee the 3 will not come up until the opposition has all his counters back into his home table. Perhaps the algorithm has to be written in such a way that it allows for novice players to have a chance, and experts to have less of one, but if you’ve been playing the game for the best part of 60 years, as I have, you may as well give up at the point where you know you’re not going to throw the number you need, because you won’t.

For the dice rolls to be ‘random’ with the results the computer gets it’s a joke.

This app is surely rigged against you! The staggering number of doubles that come up against you it is clearly evident of problems in the underlying software. It is just there to frustrate you so the enjoyment of the game is lost. Would not recommend this app.

Please can you resolve the issue which is driving me mad: the app forces you to make certain move combinations and there is no way to over write it. Sometimes the hint button does what I want but often it does not. Please can you sort this out as I’m regretting my purchase

Despite claims that the rolls are predetermined and therefore “cheating” is impossible, the AI’s dice rolls seem highly improbable—not just in terms of the numbers rolled but also when they occur. For instance, the AI frequently gets exactly the rolls it needs at crucial moments, such as when bearing off, entering from the bar, or right after doubling. This happens far too often to be mere coincidence. Furthermore, while the dice statistics might show an even distribution of rolls overall, they don’t account for the timing of key rolls, like doubles. Players often get doubles when stuck on the bar, while the AI conveniently gets them while bearing off. It’s a truly infuriating experience!

By using the hints, I can check my judgment against the games.

I liked it until I noticed how insanely often and conveniently the computer throws double or just right. If you want to have the dice roll (behave) more realistically switch to manual roll. I found it f#ing irritating. sometime 4 out of five rolls are doubles. I deleted the app, waste of money.

Best bg app around. Would suggest two improvements: First, have a setting where you can dictate your own range of Elo rating to be matched up with. The plus/minus 200 point thing is weak. Secondly, don’t include turns on the bar and forced moves in the calculation of the error rate. The error rates are inflated (deflated?) due to this. XG does not include these two things in their er calculation.
