Very happy with this app! The functionality is perfect, the different difficulty modes match what I would expect. The ads are there, and noticeable, but not so obstructive that you can't play. Best Sudoku app I've tried! One possible thing to make it better: I would really like to play with the "dark mode" coloring, but the highlight row/column color is a pretty dark gray on the black background and it makes it really difficult to see. A higher contrast would be amazing!

Hello! Thank you for playing Sudoku and sharing your feedback! I have passed the suggestion to the developer team to consider changes to the dark mode for future updates. Hope you a having a great day! Best regards, Nadia

It's pretty much a perfect sudoku app. There are banner ads that just sit at the bottom of the screen and don't interrupt your gameplay, there's even an option to purchase ad-free. You can put in pencil notes for empty squares, and it highlights the number across the board (optional). It doesn't have all the functions I would want even optionally so it's not my favorite, but it's damn good enough. 9/10 get this app for Sudoku, good job devs!

Hello Mariel, Thank you very much for playing Sudoku and for your awesome review! We are currently working on changes that would help reduce accidental inputs, as well as functions that would help learn Sudoku. The ideas for these changes have been shared by the players, so don't hesitate to leave a suggestion. ​ Best regards, Nadia

Upped my rating after playing longer. at first I kept accidentally entering numbers on the board when I meant to select them but I've got over that now. UI is clean and simple and ads are unobtrusive. first soduku app I found where the ads didn't turn me right off.
