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!

Some of it is wordy and I wish when you select something your guesses would dissappear. Also an undo button would be nice. I don't mind the error message but it's easier to just backup instead of making a mess. Id also like to see a 'could be' option instead of 'not this' some of the things are hard to read (the cigarettes lol etc. When they're small

Thank you for the review. I made a note about undo button. I'll try to add it for the next release. Not sure how to add 'could be' option without making a mess in UI. I'll try to think of something. Thanks.

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'm sorry that you feel that way. One thing that I can guarantee is that every puzzle is solvable and clues are not conflicting with each other. Usually confusing comes from how these clues are expressed. Like "next to" (at the left or right from...) vs "immediately after" (at the right from...). So yes, that could be improved.
