This is the one

Brilliant.

Needs auto fill candidates

For people with carpal tunnell

good stuff

love it. great puzzle quality. a few glitches. for example, i finish some puzzle but then the timer keeps counting for some reason, and then there’s a white flag. what’s that mean?

App Too Confusing

Don’t waste your money. This app is way too confusing to use. Sudoku is a simple game. This app makes playing it almost impossible.

Not the very best

I have the other app by Nick Carney: “Cracking the Cryptic curated sudoku puzzles” that I absolutely love. Was somewhat disappointed by this one as it’s not user friendly at all or perhaps I’m somehow unable to figure out how to use it. There are only three colours for shading the cells. I can’t select a number to see highlights of places I’ve noted it. Selection and deselection of cells is rather odd. I really dislike seeing the numbers in a line at the bottom. I wished I could somehow migrate these classic sudokus to the other app 😢

I can at most take off one star because to be fair it’s still way better than other apps apart from the one I mentioned.

Good play, unreliable hints

The game is well designed, easy to play, and offers advanced puzzles. However, the hints are sometimes wrong. Rather than use the r#r#c#c# schema, perhaps table headings with alphanumeric coding on the x and y axes may help prevent the hint errors.

Please add more puzzles

Love the app. Really wish more puzzles would be added though.

so much fun but not enough puzzles

the app was great for learning y-wings, bent quadruples and empty rectangles. i just finished the last puzzle. i need more sudokus please!!!!!!

You are only paying for 100 puzzles

Purchased thinking more puzzles will be eventually added… NOPE!!!

The best

Real puzzles created by real people, not stupid algorithms. Properly educational tips that help you develop your skills. The game play is almost perfect, just a few small niggles, like selection not being part of the undo. One big issue… only 100 puzzles. I finished them all. Please give us some more puzzles!!!!

Cool but

Cool but I lost interest too quickly

Better Tools

The additional notation you can make really helps to solve the puzzles better. Bought the app after watching the YouTube channel for strategies to solve the harder puzzles. Hope they continue to add to this app.

Great but some things missing

I love this app! The design is easy to use, navigate and aesthetically pleasing.

Two suggestions: 1) dark mode 2) upon completion some puzzles say ‘did you spit the’ and I can’t go and look at my completed puzzle to see it!

Help with settings

Have been playing Sudoku on another app but just tried this one and trying to adjust to new settings, etc. I’m unable to find a guide that explain what each setting does, which would be helpful! Looking forward to learning them one way or another and playing some HUMAN-generated puzzles.

More Puzzles Please!!!

This is my favorite sudoku app of all time. I hate playing this game in others, it’s just not the same!

I’ve been playing the same 100 puzzles for a few years now and am ready for more!!

Love the channel

Thanks for these free sudokus! I solved them all and they were really fun

Good Game a little frustrating.

I like the game but I find the hints very frustrating. They are either wildly wrong, often contradicting the given numbers or require reasoning that if you possessed you obviously wouldn’t require the hint.

Absolutely outstanding!

I love this app! Each puzzle is great in its own right and the options available to solve the puzzles are better or on par with anything else I have found. If there was one thing I would add to a wish list is the capacity to review the puzzle after I’m finished. As in the timer stops and I can go back on the history of actions to see what my process was. Specially to compare against the hints if I didn’t use them to see if I used what was hinted or if I came up with something else. But that is minor compared to everything else that this app gets right. If you love Sudoku definitely get this app!

Wishing there was more puzzles added

Love it, just wishing there was more puzzles added.
