Since this was the only license plate game I could find for my Kindle I did purchase it despite the mostly negative reviews on Amazon. It's true that as soon as you close the app (or turn off the kindle) you lose all saved plates. We got around that by playing a new game each day, but I also found that licenses would disappear. A choice that we had used the day before for a state would be gone the next day. Beside these couple "bugs" it was an easy way to track plates. One day going through Kansas and Nebraska, we saw 31 states!
