As far as I can tell there are only 3 different puzzles. The 350 easy puzzles are all the same. And the same goes for the 350 medium puzzles. I didnt even bother messing with the hard puzzles before deleting this app. Unless you actually give 1000 different puzzles you shouldnt claim 1000 puzzles. I am just glad I didnt pay for this garbage. I would give it no stars but I am forced to give at least 1 star.
