This game has obviously been changed...

It’s been changed for the worse. I already commented about the new format giving too many clues by graying out numbers etc. There are no options to turn these off. I got a new phone and I had to update to latest version. I immediately noticed that I’ve either suddenly gotten really good at this game or the makers have dumbed it down. I play expert all of the time and I used to average about 20-25 minutes per game. (I have no clue whether that is good or bad. I play it for the challenge.) But with the update my games are done in under 15 minutes every time. I’m not that good! It is noticeably easier and not as fun. I know there is no other Soduko app out there as good as this one was. I searched. But making it easy does not win me over. You’ve lost me. I’ll check back next month to see if my paid for app has been updated back to its old self.

Hi Cliff, thanks for your helpful feedback! We'll definitely consider those suggestions for a future update.

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. :)

The best. Except one kiiiind of big issue...

I love this sudoku app. It has THE best setup / functionality compared to all other sudoku apps I’ve tried. I’ve played it basically every day during quarantine. However, there is one really big issue which unfortunately has caused me to have to find a new sudoku app: As I start to play (I mostly play on Hard if that’s relevant), my phone starts to get really HOT and the battery starts plummeting. I have an iPhone 8 Plus, and I’m fairly certain it’s not a phone issue because I have many other apps that I’m on throughout the day. My phone is totally normal for everything else but this app. If I open the app and start playing at 100% battery, it will be at 5% in about 20 minutes. My phone literally gets burning hot to the touch to the point where my fingertips are legit slightly burned (visibly a little red, but mostly not visible just can feel they are clearly burned). I know I sound like a crazy person and my friends were like what the actual F,’s real! So. Yeah. 4 stars.

TLDR - It burns.
