### 4/5 — IPhone runs very hot

*2026-05-26, version 4.4*

iPhone gets really hot when I play in flight mode.

### 3/5 — Ras la pub

*2025-12-10*

Pub systématique et trop longue

**Developer response:** La publicité permet aux applications de haute qualité comme la nôtre de rester gratuites. Si vous êtes frustré par la publicité, offrez-vous la mise à niveau unique "Supprimer les annonces", pour moins que le prix d'une tasse de café. Nous espérons que vous continuerez à profiter de Pure Sudoku.

### 2/5 — Flashing red

*2025-10-15, version 4.1*

Love this app but the flashing red email link to advertisements makes it unbearable

### 2/5 — Unable to restart a level

*2025-06-07, version 4.0*

Obviously gone wrong on a
 Level but there’s no option to clear the board and start again. Very frustrating

### 1/5 — Invasive ads

*2024-07-27, version 4.0*

I’ve had this app downloaded for years. Today was the last straw. I looked away from my screen for a second and didn’t realized an ad started. I tapped on my screen to avoid my phone auto-locking. Well, I ended up clicking on an in-game ad which redirected me to God-knows-what kind of link. I really hope it didn’t download anything malicious.

Such an excellent app! User friendly, clarity of suggestions and deletions - wish all apps were so thoughtfully made.

### 1/5 — Unusable with the ad

*2024-04-29, version 4.0*

This app has an ad running that needs to open a browser every 20 seconds. In itself, that is annoying enough, but it opens to an insecure URL that is blocked by the browser. It is now completely unusable as a soudoku puzzle app.

The app allows you to check for errors, but it marks red incorrectly, then when you recheck, it corrects itself., The good . . . wait . . . . Ah, better way of selecting your choices. At the end of the day, I ended up deleting the app, mostly because they opened me to malware.

There are pluses and minuses. It’s intrusive ads are videos, which makes the game a top batter drainer.
