Not worth the time and money.

It seems like the puzzles are computer generated (not artist created). That it a bummer because many times the challenge is taken away by obvious solutions.

The user interface is very buggy. Selecting a box and then a number can be very frustrating. The number may be 300 pixels thick but only ten of them actually select the number you are trying to select. Then, ten number selections later that box that was giving you trouble before returns to plague you by mysteriously changing numbers on you. That requires you to once again find those ten special pixels, but this time the box changes back and laughs at you every time you finally manage to correct its spiteful shenanigans.

The app has many fun puzzle types to choose from. But until the developer chooses to put some time into making it work properly, the risks out weigh the fun and is therefore not worth its time and money.
