fun game and love the subjects!

Blue Pine

I just got this today, and love it so far! It works just right, and I bought the 2nd pack too. I might try the other pack when I run out. There are lots of different subjects, and they even have a UFO puzzle - definitely something for everyone! Especially in the Age of Seti and exoplanets! :) Gotta love it!!! If you like logic puzzles, this is the real deal, with lots of difficulty levels. If you've never tried logic puzzles, you're missing out in my opinion. I'm an addict now though, so watch out! It's that kind of puzzle!

It’s ok


I downloaded this app yesterday, and I’ve already finished all 20 free grids. Seems a bit ridiculous to charge $1.99 each time you want more. Just not challenging enough. I did not find any errors in the clues as others have claimed. The point is to be a bit confusing. I’m deleting the app now because I’m not paying $1.99 over and over, and there’s nothing left to do after less than 24 hours from the time I downloaded.

larger displays needed

The puzzles are very good. They are creative and challenging. The difficult thing--reason for the low rating is that the grids are too small and when you get to the squares on the edges it is difficult to tap them and gets frustrating. The grids should be made where they are expandable. Otherwise this app is great. Should minor fixes such as being able to increase size especially on larger puzzles I would purchase additional content.
