5 stars: Great app. Difficulty can be from very easy to extremely challenging. Every puzzle is solvable with logic (no trial and error) and there is a button that tells you if you made any mistakes. If only there were more free levels available.
4 stars: Great game, and we'll designed. I would give it 5 stars if it had more free games (at least one a day, currently it gives one a week, and a very simple one), or if prices for packages were not so over the top.
5 stars: Great interface and reliable. Nice choice of puzzles. Wonderful app.

4 stars: Sleek and smooth. No bells, no whistles. Nothing extraneous either. Now that it's asked me to rate it, I might get some ads but none so far.
