Ratings and reviews

I have been playing this version of Einstein puzzle and others, some no longer available, for years. I can affirm that the app is stable across multiple Android device brands and that I have yet to encounter an error and I've played hundreds of games. Really appreciate the upgrade too as I didn't think it was still supported so yay!

Full of errors, to elaborate. Running larger puzzles causes the game to give incorrect and conflicting clues that end up making the puzzle unsolvable. For example giving clues for different items in the same slot so that it will give you an error no matter which you chose. Other times choosing the right choice gives you an error even though when you un select it and select again, it works fine.

I want my money back since I wasted it downloading this app to use it 1 time for 10 minutes before I discovered that it's terrible and almost impossible since it does not have enough helpful clues, no way to mark out or erase listed items that do not go with that column. Fix those two things and I'll try the app again, unless you charge me again to reinstall it.
