The best sudoku Ive tried....and Ive tried a lot of different Skodoku apps. I download them .. try a couple puzzles .. then delete them. But not this one! Im addicted to it. Most user friendly of them all. Love their hard puzzles.....except there arent enough of them. The irregular and diagonal are so fun. I have even been able to complete all the 16x16. I love this app.
