Unfortunate update

I like this app but wish I hadn't updated. Now the statistics (prev. scores) are hard to read and in a ridiculous scroll box. When you complete a game that makes a high score, you are no longer notified. It's galling that the developer calls these regressions 'improvements'. When does the next version come out?
What I wish they would have fixed: my app consumes 400MB and climbing, most for app data. What could it be storing?? The board and scores consume a minuscule amount of space. Of course I could delete and reinstall, but I would lose my game records.
Other vast improvements would be not disappearing the board the second it's complete; and improving the ad experience (esp. the obnoxious audio ones (usually I'm listening to my own music while playing)).

If you haven't updated your app yet and are still using a version from before September 9, 2018, DO NOT UPDATE. The game no longer works with that update. It will not even register that you are touching the screen. In spite of numerous reports and complaints, the developer has yet to do anything useful about it.

Previous review: Simpler is better! After using a few programs with silly bells and whistles, this is definitely my favorite. It best replicates the comfortable feeling of doing the puzzle for yourself, rather than to necessarily beat the clock or hit a certain score. You have a clock if you want to beat it, but its presence is unobtrusive and pressure-free. You won't get hit by onerous penalties if you touch the wrong number or button (unlike a competing version that I have since uninstalled) and it's pretty hard to hit a wrong button anyway, because everything is arranged so well on the screen. If you DO feel competitive, you can check your position on the leaderboard and keep an eye on the clock, but none of the competitive aspects will ever get in the way of those times when you just want to relax with a favorite number puzzle. Get this Sudoku app and you'll forget all about the others.

Hi Lara, thanks for your review. So sorry you were experiencing this issue, and for the delayed response. We have since then fixed this issue. We hope you'll check out the most recent version of the app and consider updating your review. :)

Impossible to do...

So, I had thought that I couldn’t finish the puzzles on the ‘hard’ level because I had it on that level of difficulty... but I always encountered the same problem... Every single time I tried a puzzle on ‘Hard’ difficulty, I would get the puzzle close to being done and then would not be able to make a single next move.. and this happened A LOT. I would come back to it the next day and double checked multiple times and still could not go anywhere with what there was unless I just guessed a number.... so I would have to end the game and start a new one. i have been playing sudoku for a very long time and have never had this problem before. And then today, I played on ‘Medium’ and the numbers that are already set have the 9s placed to where it’s impossible to put a 9 in a box section that needs a 9. I have a picture to prove it. It just makes no sense and the numbers given to start out with are poorly set up to where it’s impossible to solve. So now I’m thinking I wasn’t crazy when I couldn’t finish the puzzles on ‘Hard’ difficulty when that is usually the level I play on. Will be deleting...
