### 5/5 — Great sudoku app

*2026-08-17*

Great puzzles, lots of variations, hints are actually helpful and the premium is a lifetime so more than worth it.  And weekly themed puzzles every week.

**Developer response:** Thank you so much for the wonderful 5-star review, and for supporting us with the Lifetime premium. The hints are built to teach the next logical step rather than just hand you the answer, so we are very glad you find them genuinely helpful. Enjoy the weekly puzzles.

### 5/5 — Melhor app possível

*2026-08-16*

Pra quem gosta de variantes, esse é indiscutivelmente o melhor app. Atualizam o app com novos sudokus frequentemente, possuem a maior quantidade de variantes interessantes e alguns bem difíceis. Mas o melhor são as questões de qualidade de vida como seleção múltipla, cores, anotações, tudo. Já bichei muito Sudoku e esse é disparado o melhor app.

**Developer response:** Thank you for your review.  Our app is our passion and we'll never stop supporting it. We are working on a major new release of the app. We have improved the hints and the strategies in addition to many other features. It takes us a bit longer than usual but a new release is coming in a few weeks with new variants and new puzzles.

### 5/5 — Best game ever

*2026-08-08*

It’s been my favourite game for years now. I’m addicted to logical games and puzzles and this is by far the best one I’ve ever played. Only subscription I pay for and haven’t regretted.

**Developer response:** Thank you so much for the wonderful 5-star review! Knowing this has been your favourite for years, and the one subscription you don't regret, means a great deal to us. We will keep adding puzzles and variants to keep it worth it. 💙

### 5/5 — 100% worth

*2026-08-08*

If you enjoy Variant Sudoku this app has it all, premium is a very reasonable price to pay for so much. Any puzzle below hard difficulty is extremely easy in my opinion but there’s so many challenging puzzles to go through.

**Developer response:** Thank you so much for this wonderful review. We're very glad you find the variants worth it and that premium feels reasonably priced. Thank you also for the note that puzzles below hard feel too easy, we have passed that on to the team.

### 5/5 — Fantastic variants!

*2026-08-04, version v4.2.3*

Very interesting and challenging variants. Very well designed app.

### 5/5 — Topp!

*2026-08-02*

Bitte die Anzahl der Ladebildschirme reduzieren.

**Developer response:** Thank you for your review. We are very glad that you enjoy our app.

### 5/5 — Super!

*2026-07-25*

Meilleure appli de sudoku!! Je suis abonnée premium et ne le regrette pas, ce jeu est génial! Les variantes le rendent passionnant et l’ergonomie est top! Mais un bug depuis la dernière mise à jour: Quand on colore une cellule puis on y met un nombre, la couleur disparaît!!☹️ Pouvez-vous corriger cela? Merci et bravo

**Developer response:** Thank you very much for your 5-star review!!!

### 1/5 — Premium ad in app

*2026-07-23, version v4.2.3*

I got an ad to go ‘lifetime premium’ after I am already ‘lifetime premium’. Test your apps and updates. Unacceptable.

### 5/5 — Besser geht es wirklich nicht!

*2026-07-20*

Ganz klar das beste Spiel meines Lebens! Ich liebe es. 😊

### 5/5 — Excellent

*2026-07-18*

Excellent access to variant sudoku, using varying gimmicks at. Varying levels.  However, zip lines having been defined as covering an odd number of cell, I have encountered a puzzle with evenxelled zip lines. I suspect they have been wrongly coloured.  X Terence Clarke

**Developer response:** Thank you for your review. All our puzzles are tested for accuracy and single solution. If you encountered Zip line with even number of cells, it is probably because the first and the last cells are the same, which makes the line an odd number of cells and logic wise it mean that the center cell must be even number. I hope this helps.
