5 stars: Excellent! I love the choices of levels, rather than being forced to advance. I am handicapped and depending on the day I can work at a level that is workable for me. Also, I appreciate the ability to self check as I progress if desired, this facilitates learning much better than just finding out at the end. BRAVO to the designers, and a big thank you.
5 stars: I cannot believe how AMAZING this app is. I am now combining it with Andoku Capture. I photograph the extremely difficult puzzles, get them as far as I can, then ask for a hint. THEN, in incredibly clear tutorials this app teaches me techniques I cannot learn anywhere else. I could not find these methods explained anywhere else. If you SERIOUSLY want to learn how to solve the most difficult Soduko, get this app!! THANK YOU.
4 stars: This app is an awesome sudoku app overall. I would personally recommend this app to any beginner wanting to get into sudoku and to any casual or advanced player. Although I couldn't pronounce myself on the expert side, Because I am not one. PROS: great sudoku app overall, tutorials for different techniques, no ads during sudoku so yoi don't get distracted, a lot of settings customization CONS: no practical applications for the tutorials
5 stars: other than the annoying ads, this is a fantastically fully featured sudoku game! it has many levels of difficulty, tutorials on all the techniques, auto deletion of candidates when a # is selected, checking, back button... even ...
