5 stars: Excellent challenge, kept me engaged for hours. The puzzles are well written. The developer(s) has done a brilliant job. If you have an Amazon Fire 8 HD use the Amazon app store rather that Google Play Store to install this game. Thank you for the support you gave Developer. 😊👍
4 stars: You fixed my issue with app crashing and it's been great for a while! Thanks! My newest issue is that you have larger ads at the bottom and they cover up the bottom row of the puzzle so you can't play fully. Old review: I love this game, but it crashes on me non-stop. I've had it on my phone for a while and played regularly with no issues but the last couple of months it crashes all the time.
4 stars: I really like this game. If you're looking for some good brain teasers this is it. Barely any ads. Lots to choose from. Not hassling you for real money, just nice relaxing brain stretching fun. No glitches so far and I've had it at least 1.5yrs. Only four stars cause it seems like very few puzzle can't be solved with the hints given, but not a reason not to download this game. Thanks creators for creating this variety of puzzles👍🙂
