Pretty good
Pros:
Starts up pretty quickly and jumps right back to the puzzle you were solving.
Unlimited puzzles at 3 difficulty levels
Some nice info on puzzle solving techniques.
Areas for improvement
- It would be nice to be able to enter a custom puzzle like from a newspaper
- Not a big fan of the greyish tint on some of the boxes.
- The pop-up number chooser obscures whatever is underneath. An alternative would be having the numbers in a row below the puzzle which some other apps do.
