Updated to 5 stars after upgrading to pro. The "no adds" does apply to the auto notes which is great. It's a great, no frills app that does what you want: give you sudoku. I still think that "expert" needs to be split as some require some pretty high level tricks to solve. Suggestion: Right now, if I get stuck, I don't want a hint, I want to know what I'm missing. 'sudoku.coach' has great analyzer. I'd love an equivalent feature or an easier way to transfer to that site's analyzer.

Hello! Thank you for playing, supporting us, and sharing your feedback. We are interested in a better hint option ourselves and are looking into ways to implement what is usually referred to as "Smart hints" to explain the next move. If you'd like to discuss smart hints, contact us at sudoku@digitalchemy.us. Best regards, Nadia

EDIT: As soon as I left a 5 star review about how there were no unskippable ads, it started showing unskippable ads. :/ ORIGINAL REVIEW: This is free app you're looking for! You don't have to watch ads just to play. The banner ads at the bottom are unobtrusive. I am very very pleased, and very glad I found this. Ads with multiple presses to exit after waiting—before and after every game—in other apps were driving me absolutely crazy. And then it still has all the features you'd want on top!

Hello! Sudoku uses ads to support its development. We understand that ads are a compromise - we don't have ads in the middle of the game, and ads that appear after the game should be significantly shorter and skipable. If you are seeing very disruptive ads, a screenshot report at sudoku@digitalchemy.us would be very helpful. Best regards, Nadia

3$ premium is so worth it, especially in comparison to other Sudoku apps which charge upwards of 12 dollars for half these features. It is easy to use and enjoy. I think it would be nice to be able to customize the dark mode color themes a bit more, but there is tons of actual game play customization to make up for it.
