I love backgammon and have been playing for a few years now. It can be hard to find people to play at times and find people with same or greater skill to challenge myself, so I play online or against bots. A problem I have with other apps is that as I play my skill increases the bots do not, so with other apps I know when the bots have made critical errors and I can the exploit it.
This app gives you a good incremental challenge. Even the "easiest" posed a challenge when I first starry using this app. The hint button gives some good tips and you can use this as training "why is this a better move?"
Great app and worth the $
