Horrible
Hate that this is advertised as “pen and paper” and has way to many options and auto tells u what potential numbers can fill boxes without the option of turning it off. Deleted immediately and even decided to just pay $14 on a dif app with no adds. Why do all sudoku apps overcomplicate things.
Crashes all the time
Game crashes all the time, if you close out, complete a puzzle
Love it, but it crashes a lot
It’s testament to how much I enjoy this app that I’m still considering paying for it when my Arcade trial runs out even though it crashes all the time. I can only safely play a single game at a time before reloading the app, starting it can take a number of tries, and it won’t tolerate switching between apps or even pulling a phone menu into focus, like to skip back in a podcast if I didn’t quite catch something. True to its name, it’s good enough that other phone sudoku disappoints. I just wish it loved me enough to be reliable.

Love it
Has improved my sudoku skills, really fun to use.
Color schemes not ADA complaint
The color choices in places are very low contrast light blue text on light green background (might have been reverse). Could not figure how to progress in note taking tutorial. Need an option to turn off the various colors put into cell background or explain them. Very frustrating to play.
Recent Issue
I used to be a daily player until about a week ago. The app no longer loads past the loading screen, and remains black. Really missing the daily puzzles.
Please move hint button
Great Sudoku app, but please move the Hint button. I’ve accidentally hit it numerous times when trying to tap the red slash button instead. It’s disappointing when trying to complete the puzzles without using Hint until I absolutely have to resort to using it.
Game crashes
Game crashes after each game
Gives away the answers
Removes the thought from the puzzle. Click on a box and it tells you what numbers are available and removes all thought from the game and over simplifies the puzzles.
Problem writing numbers
I am trying this app & started playing daily and could not get number

It’s great, get it.
However, the HINT button is too close to the others, which makes it easy to occasionally misclick and use a hint when you don’t mean to.

Casual Players Punished
It’s insulting that I’m periodically reduced to beginner just because I have a life and can’t always finish puzzles. It will literally let you advance to expert and then demote you to beginner if you go a few days too busy to play. This is terrible design.
GOAT Sudoku
I love coming back to this game over and over throughout the years! It’s always such a pleasure! The last update was four years ago so I’m not holding my breath BUT it would be nice to add a game mode that advances the difficulty after several games. Like start out beginner eternal and work your way up. Either way! Beautifully made game!

Almost great
Mostly wonderful app, but (1) the most difficult techniques are taught in a very confusing way, and (2) many techniques rely on knowing what was or wasn’t pre-filled on the board, but there’s no way to tell once you’ve started the game. There should be a different font for items we’ve filled vs items that came pre-filled. Would be a very easy fix.

Save and quit bug?
App is great but there appears to be a bug whenever I use the ‘save and quit’ option as the app keeps shutting down and I have to restart the puzzle
It’s the little things
The broad strokes and overall experience is great, but when it comes to both the best and the worst of this app, it’s all in the details.
I love that it detects if you’ve got music or other content playing in the background when you open it, and mutes the in-game music if you are. I love the sound design that makes it so satisfying to clear out the last of a puzzle in one long chain. I love the practice modes for specific techniques.
But I don’t like how opaque the scoring system is. I don’t like how eternal mode doesn’t give you a button to return to home after finishing a puzzle. I don’t like how the eternal mode puzzles can vary so much in difficulty without warning, such that how well you do is incredibly luck based.
And I wish there was support for sudoku variants like sandwich, thermo, and arrow. I wish the training was more extensive. I wish arcade mode could somehow be a little more intelligent about letting you correct legitimate typos without so heavily penalising it as a mistake. I wish it wasn’t so laggy when you first open it and I wish the music didn’t double up sometimes.
But overall, it’s a good sudoku app. Which is exactly what it set out to be.

Bad game
Stopped my game and said the puzzle was unsolvable when it was clearly easy to solve.
Best current Sudoku app I can find, by far
Since Sudoku 401 stopped being updated for new iOS versions, I’ve looked for a replacement in vain, using a clumsy non-mobile-friendly web app whenever I wanted to solve a Sudoku.
Until now.
This game has actual challenging puzzles that require nontrivial techniques, and tools nicely designed to help you apply those techniques. It looks nice, and has a UI that seems to have been designed for mobile, and for extensive use. And it even has some nice uncommon UX, like a way to quickly rewind to before you made it unsolvable. While it has some unnecessary gamification, there’s not enough to get in the way. I haven’t gotten too far into the tutorial or the hint system, but what I’ve seen so far looks great.
Still, as unfair as it is to compare this to a game you can no longer even play (that also benefited from years of me getting used to its quirks), it doesn’t make me stop missing 401.
The biggest problem is that the UI is significantly busier, making it harder for the stuff you care about to jump out at you. Most notably, you rarely care about the difference between a 1-3-8 and a 1-3-red4-8, but that red crossed-out 4 is highly visible, preventing you from noticing that it’s one of three 1-3-8s.
Also, the auto-complete is weird, the way it jumps in as soon as you pause (with singles to be automated) but then stops after doing a single block. On a mobile app, you want even more automation than a PC or web app once you’ve done all the challenging bits (or once you’ve done one challenging bit and want to fast-forward to the next); 401 wasn’t as good at this as some of the desktop apps, but this one seems to be even less so.

Constant crash
I’m mostly just playing good mode, impossible - core. I’m at around 400 games, and now every game would crash at some point, whether is saving, winning, or swiping down to adjust screen brightness. Most of the time no progress is saved and I have to start over. This doesn’t happen as frequently in other modes. Is it a memory management issue b/c I have too many unfinished/finished games?

Unplayable
Low contrast makes it impossible to play for more than a couple of minutes.
