Best Sudoku App

Perfect for beginners and extremely advance players alike. Tutorials are excellent at teaching you the advanced (and beginner) techniques. Hints are perfect as they start by just pointing you in the right direction, then explain in great detail the relevant technique, which improves your ability to spot the more advanced techniques. And you can scan any puzzle from a newspaper or book or website. Highly recommended!!
