### 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

### 4/5 — Love the app, hate the battery consumption

*2024-06-22, version 4.0*

The title says it all

### 3/5 — Mixed Bag

*2024-04-25*

There are pluses and minuses. It’s intrusive ads are videos, which makes the game a top batter drainer. It allows you to check for errors, but it marks red in error, then when you recheck, it corrects itself. Wait, the good. . . . Ah, better way of selecting your choices. Though I listed more negatives than the positive, I still use it over other games.

### 3/5 — Over heats my iPhone

*2024-03-25, version 4.0*

This app is over heating up my iPhone 13 Pro

### 2/5 — Data hungry

*2024-02-02, version 4.0*

I have uninstalled this app due to data sharing requirements and the constant need to update preferences. A ‘reject all’ button may encourage me to reconsider but until then I’ll find an alternative app.

### 4/5 — Better than other free ones

*2023-10-22, version 4.0*

I like that all adverts are shown on top the frame and not interrupted in midst of doing the sudoku.
There are couple of things that I find it in convenient.
It can’t be done in panoramic view on iPads. As such the numbers are at the bottom.
Sometimes it doesn’t flag errors even though the segment is completed. I have to check for errors. 
I enjoy doing the puzzles.

### 2/5 — Drains my battery

*2023-05-28, version 4.0*

I do like this app, but it does make my iPhone 11 run very hot and drains my battery quickly.

### 5/5 — Love the app

*2022-08-15, version 3.2.5*

I love your app.  However, you can make it more enjoyable if a game that I am playing on my phone would crossover to my iPad

### 4/5 — Sudoku

*2022-08-03, version 3.2.5*

Its good and doesn’t allow cheating

### 2/5 — Numbers

*2022-07-20, version 3.2.5*

It would be better if the numbers disappeared when they are in every box as in all the twos are in every grid box so the two goes from the pick box

### 5/5 — Sudoku

*2022-06-03, version 3.2.5*

Perfetto

## Most critical reviews (10 lowest-rated)

### 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.

### 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.

### 1/5 — Mixed Bag

*2024-04-28, version 4.0*

There are pluses and minuses. Ads area problem. It’s long intrusive ads are videos, which makes the game a top batter-drainer. The advertisers can take over. Recently, Pure Sudoku force opens trackmenow.life There are other issues. 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.

### 1/5 — Pubblicità

*2024-01-25, version 4.0*

La stringa della pubblicità copre la tastiera numerica e impedisce di giocare. Raccapricciante!

### 1/5 — Sudoku

*2023-11-12, version 4.0*

Ho pagato per non avere pubblicità invece ogni tre minuti viene fuori quel dannato re o qualche altra cosa. È un imbroglio!!

### 1/5 — Consumo eccessivo della batteria

*2023-03-17, version 4.0*

Dopo l’ultimo aggiornamento il consumo della batteria è aumentato a dismisura. Durante l’uso il telefono si scalda parecchio.

### 1/5 — Repeating puzzles

*2022-05-27, version 3.2.5*

Same few puzzles keep repeating. Like 4 or 5 puzzles repeating. Definitely not 500 different ones…

### 1/5 — Hard to play

*2022-05-01, version 3.2.5*

Wish it had different colours because being black and grey hurts my eyes also once one numbers is filled in it would be better if that number disappeared

### 1/5 — Terrible

*2022-03-08, version 3.2.5*

Entered numbers too small to see Couldn’t even get clock to stop or anything else for that matter when I finished the game Number choices should disappear when all are entered I paid to have no adds before I played a game. Don’t make that mistake, play first. You might not like this app.

### 1/5 — Horrible intrusive irrelevant ads

*2022-02-26, version 3.2.5*

Really destroys the experience

## Most praised reviews (10 highest-rated)

### 5/5 — Excellent design and construction

*2024-05-13, version 4.0*

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

### 5/5 — All good again.

*2024-02-07, version 4.0*

Fun app. Very enjoyable.

### 5/5 — Almost perfect app

*2023-09-23, version 4.0*

It does what it should. It’s simple and it works. All the fun and no irritating ads. It just took me a while to figure out to hold the number down to fill the square. Couldn’t find the instructions easily, but probably just me being too impetuous!

### 5/5 — Genial

*2023-08-27, version 4.0*

Buenísimo para ejercitar

### 5/5 — Brilliant app

*2023-08-09, version 4.0*

In my opinion, the developers have really though this through and created a brilliant app. I cannot fault it. Excellent job!

### 5/5 — Perfetta

*2023-05-01, version 4.0*

App perfetta, divertente , tantissimi schemi da risolvere.

### 5/5 — Best Sudoku app

*2023-03-20, version 4.0*

I love this app simple no annoying music or noises just lets you concentrate and solve the problems. I have progressed from beginner to Master I just wish when I finish the last of the Master section I could get another 500 to tackle. Fantastic app highly recommended

### 5/5 — SuperSudoku

*2023-03-07, version 3.2.5*

Sehr schön gemacht, ohne Schnickschnack. Man kann sich gut einüben bis die nächste Stufe erreicht ist. Und jederzeit kannst Du dich in einem Schwierigeren Level messen lassen.
Top! Fünf Sterne

### 5/5 — Ads back and forth.

*2023-02-21, version 3.2.5*

Great app, seriously. 
However 
Occasionally causes irritation. 
It is free and ad supported. 
They offer an ad free experience. At a very reasonable cost. 
At some future point the ads may come back and the ad free choice will go away. 
Needs removal, reinstall twice. 
I have written to the developers and they replied positively. 

So far so good

### 5/5 — Eindeutig das Beste

*2023-01-09, version 3.2.5*

Richtig gutes Sudoku. Habe mir nach kurzem Test die Vollversion gekauft. Der Preis ist mehr als fair. 
Schön wäre es, wenn man das Sudoku auch in Querformat nutzen könnte. Wäre von mir ein Verbesserungsvorschlag.
