Good puzzles, allows mini numbers and color coding. And best of all, NO ADS! My only request is to highlight a square after a couple seconds, and the ability to toggle a highlight of certain numbers. For example, if I'm trying to focus on 2s, I'd like to highlight all the 2s. Also, if 9 of a certain number is places, they could change color and not show/gray out on the keypad anymore, maybe?

Time taking problems. That's what I like. They produce a nice set of difficult sudoku solving problem. Each level in accordance to their difficulty. 9/10.

The only reson for this 5-star is the stupidest 1-star review ive seen complaining about obnoxious ads when there is clearly no ads, i don't like sudoku but i don't like people who give 1-star ratings to something that isn't even an annoyance in the first place, so this will be a message to others, actually look into the games before you review it, so to the creators, thanks for the first game without ads ive ever seen, this 5-star should help the game just a bit more, that's all I will say for now.

I don't know how anyone could give this less than 5 stars. Zero ads freeware no Wi-Fi game with all the features of a paid game or ad choked game. Must be competing developers who want you to watch their ads.

I spent few hours for solve one level, and when it was solved timer don't stop, I check all several times - all digits is dark . All right. But timer keep going level don't stop. Game just allow only one right variant. And now I want to ask . How this game was born ? You check every cell with right digit inside ? Why you don't check the rights instead of check every cell ? I understand, it's free. But common I killed few hours of my life, I can write better in JS.

Was nice at first, but I would say 10 to 20 percent play were not successful because the app would not be able to reject or accept my results. I think there is an inherent flaw in the validation of the result where it doesn't cross-check the results.
