### 4/5 — Undo needed

*2026-01-17*

Nice app, but needs an undo feature

### 1/5 — Was great

*2025-12-12*

Used to be a great app but now it’s pushing ads like no other. Ads were part of it that was fine to deal with but latest update pushes ads too much. If you even pause the game you have to sit through an ad to get back to the same one you’re already playing. Junk game now that is being deleted!

### 1/5 — WILL NOT SYNC

*2025-08-28*

I purchased this game on my iPhone, iPad ad Mac k pro because it said it was able to sync between devices. Well, they don’t Thanks for the deception!

### 1/5 — Mac purchase on IOS

*2022-09-13*

i purchased the paid version on mac thinking i could use it across all my devices but the paid version only works on mac. annoying and not what was advertised

### 3/5 — Okay, but I’ll shop around...

*2021-05-08*

Pros: nice theme and design customization. I really like the dark mode option.

Cute gamification with the levels, profile pic and daily challenge.

Cons: 

Full-screen ads that block and interrupted are a pain. 

The multi-number selection option could be better. I’d rather “paint” each number in one after another than select all the cells first and then set the number.

Doesn’t ask permission to access my photos for profile picture. Usually if you click a feature that wants to access something like your photos, or camera, or mic... there’s an extra bit of security thats set in place to ASK PERMISSION. This app doesn't and it’s kind of concerning.

### 4/5 — 数独好き

*2020-09-27*

slide overでできる数独を探していて、2、3個しかない中で、1番良かったです。個人的には、入力箇所を選択してから数字をタップするよりも、数字を選択してからポンポン連続で入力できるタイプの方が操作が楽で好きなんですが、ペンのジェスチャーがあるので、慣れると結構快適にできています。ダークテーマだと選択数字の色がわかりづらいと思いました。

### 1/5 — Has political ads

*2020-07-29*

Awesome game but ads are political. We are bombarded in every area of our lives with politics, many people use games to escape from the BS. I understand that free apps need to be supported by ads but political ads have no place in an app of any app. After each game I get a Biden ad. I don’t care if it is Biden, Trump or anything else political it has no business here. There are too many Sudoku games out there that I can download. I will be finding another Sudoku game and deleting this one. Developers, keep your politics to yourself.

### 5/5 — i love this gamei am
