Hands down best sudoku app

I don’t normally review apps, but honestly this is the absolute best sudoku app I’ve tried, especially for all the variations out there. There’s tons of different puzzles using all sorts of combinations of variations on sudoku, and the developers add new variations now-and-then to keep things fresh, including ‘challenges’ for special events and holidays.

The app does a good job explaining the rules for the different puzzle variations and these tips are always just a button press away when working a puzzle.

They also give you a fairly wide set of tools to help solve puzzles. Pencil marks, coloring, helpers for sandwich and killer variants, and more. I’ve always felt like I’ve had every tool I think I need (and some I didn’t know I needed) when solving puzzles. And just like variants, it seems like the devs introduce new tools now and then to help players along.

The hint system is fantastic. It doesn’t just fill in a cell for you, it tries to explain _why_ you would put that number there, helping you learn more of the logic behind the puzzles.

This was one of those apps that I absolutely did not mind paying for to remove ads and shoot some money to the devs. They’ve done a fantastic job, and I’ve lost more hours than I can count doing puzzle after puzzle in this app.
Thanks for a great sudoku experience!

Top sudoku app by far

I've used the sudoku app with 1.3M downloads, cracking the cryptic's classic sudoku app, and this one. Before last week, CTC was my favorite app - but once the devs pushed out an update to long press to select multiple cells, this app has become the top sudoku app with the best UI, especially with that new feature being combined with double notation (two different sets of notes you can label your sudoku with where most apps only allow one).

Otherwise, all the puzzles look to be handcrafted, so unlike computer generated puzzles (which is what the main sudoku app seems to do), there's typically a very logical path to solving the puzzles, and it feels great when you figure it out.

Overall best sudoku app on the App Store, super underrated. Give it time and marketing and hope this app gets more recognition!

Error Limits

I used to love this app. It was far and away my favorite sudoku app, but after the recent update it’s far more stressful to use than fun. Most of the “errors” I make are just misclicks in which I tap the wrong cell or number by mistake, but I’m being punished for this while solving. This “feature” does not make me better at the game. Why would I be playing a sudoku app in my spare time if I were just going to solve the puzzle by correcting displayed errors? I understand that I could change the settings to check for errors less frequently, but I would prefer to know if I made a true error immediately rather than after I’ve filled half the board with mistakes. I do not mind the ads, as I know the devs need to make money for their work. However, these could just play between puzzles instead of ruining the in-game experience. I am also not willing to pay the ridiculous repeating subscription fee to return to the previous state of the free app I once loved. I hope these mistakes are fixed, but until then I will be looking for a new sudoku app.

Thank you for your review.
First, one of the error settings, handles situation of errors resulting from a slip of fingers... look at the settings!
Second, You have 6 errors!!! before the game is over. In our opinion after 6 errors on a single game, whether you watch an ad or not, the game lost any 'sporting value'.
Third, The is a lifetime payment option.

In any case, we are sorry to see you leave.
