### 5/5 — Best of the bunch

*2026-08-05, version 11.0.10*

I downloaded a “few” of these apps, and, once I became familiar with the interface, this is the easiest to use and has clear differing difficulty levels to choose from… some days I just do 3 or 4 easy ones, other days I get a bit more adventurous…

### 5/5 — nice and challenging

*2026-07-04, version 11.0.10*

it grows on you!

### 5/5 — Excellent brain trainer

*2026-05-18, version 11.0.10*

I used to play Sudoku on paper many years ago and enjoyed the brain power challenges that came along with the levels of difficulty. Sudoku on my hand phone is definitely a more convenient game.

### 5/5 — Все отлично работает.

*2026-05-13, version 11.0.10*

Все отлично работает. Чуть непонятен режим подсказки, но это не страшно

### 5/5 — Sudoku Game

*2026-04-20, version 11.0.10*

Very good game to improve your inteligence.

### 5/5 — Great simple game

*2026-04-09, version 11.0.10*

Play it

### 4/5 — Sudoku

*2026-03-22, version 11.0.10*

The ad info bar at the top of the game screen is a huge distraction and is better suited at the bottom of the game screen.

### 4/5 — Just works

*2026-03-14, version 11.0.5*

It just works though the difficulty might be average for professional players.

### 5/5 — Great fun!

*2026-01-22, version 11.0.10*

Sudoku at it's simplest, cool background and good puzzles

### 5/5 — Top

*2025-12-15, version 11.0.10*

I’m enjoying it very much but I’m a beginner. Nothing needs to change. I will love it this way for years to come.
