This used to be my second favorite sudoku app, due to satisfying difficulty but hated the user interface. Then one day I thought I found a bug in the puzzle emailed the dev and he emailed me right back, so I told him my suggestion about the interface. Today I jumped on for the first time in a few weeks to learn he got the change deployed and the experience is even better than I expected, love it!!

This is a great sudoku app! The app itself is nice and has all the features you want in a sudoku app. But the puzzles are where it's at! There are 4 types of Sudoku puzzles to choose from which gives a good but of variety. You do have to pay for the puzzle packs, but the puzzles aren't computer generated which sets this app apart from the other Sudoku apps out there, making these puzzles more interesting and fun to solve. I'd highly recommend this app to anyone that loves Sudoku!

I enjoy all the variations On the mega size puzzles I wish there was a way to enlarge the block. My eyes have trouble seeing the tiny option numbers.
