I've spent over 3 years with this app. Lots and lots of puzzles. 2 issues. 1. Ads at the end of game are loud and embarrassing. About 10% of the ads cannot be canceled out of and you must close the app to turn off. With the other 90% offering an X after 10 seconds. 2. True Sudoku MUST ALWAYS have a logical next move. This game cheats a little. 50% of hardest level puzzles require 1 to 4 50/50 guesses to solve. This goes against the purest rules of Sudoko.That being said, I've never lost.

Thank you for your feedback. It's nice to hear from a long time user! I'm not a big fan of the advertising either. I've been considering offering the ability to disable ads for $0.99 through an in-app purchase. Is this something that may interest you? If there's enough interest I may add that to a future release.

Wonderful game, simple and fun. I would like if there was a way to auto fill any cell with the possible numbers in notes mode.

Great little brain teaser/trainer, clue section isn't the best, just tells you what you already know. still great though.
