### 3/5 — Informative but updates needed

*2026-02-16*

It’s a cool tool but needs and update! Scrolling feature is buggy, and additional links to learn more about the strategies would be helpful.

### 2/5 — Nur Englisch

*2025-12-13*

Wäre sehr schön, wenn es eine Sprachauswahl zu Deutsch geben würde. Bin zwar nicht schlecht in Englisch, aber übersetzen und gleichzeitig die Strategien lernen, funktioniert bei mir nur schlecht.

### 4/5 — Helpful!

*2025-04-23*

Difficult to navigate (scrolling with two fingers can be difficult in the small area that allows it), but the app really helps explain all the strats that you can use to beat any sudoku level that you may come across. Plus it’s free!

### 2/5 — Tips would be great if they worked!

*2024-11-15*

I’ve been on the hunt for a sudoku app that can teach me the different techniques, I thought this was the one until I tried to read one of the tips only to find that I couldn’t scroll down to read it properly 🫠

### 1/5 — It doesn’t scroll

*2024-05-02*

Strategies do not scroll, else great concept. Fix and I buy

**Developer response:** Thank you for your feedback.
You can scroll the hints with 2-finger-mode, 1st finger: tap the box, 2nd finger: scroll the hints. 
Sorry for the inconvenience.
