Just Sudoku is simply what the name suggest. Lots of unique regular sudoku puzzles wait for your solution.

The new Apple Watch extension gives you a quick sudoku-fix when you are stuck waiting in line.

Just Sudoku was made by a sudoku fan, who was annoyed by all the apps that were feature overloaded.

Therefore it is very simple and to the point. Omitting superfluous frills.

Simple straight-forward puzzle solving like in the newspaper. Ideal for casual playing.


- Tons of unique puzzles

- Classic and jigsaw board layout

- 4 difficulty levels

- Hinting on a cell by cell basis

- Dark friendly version (doesn't hurt the eyes and bother others, when playing at night)

- Smart buttons (great for beginners or more difficult levels)

- Customize font and number sizes

- Landscape and portrait modes

- Take notes with pencil markings

- Display where numbers are already placed in the puzzle.

For all the pros out there: these sudokus will not need advanced solving methods such as X-Wing, Swordfish, Jellyfish and Co. to be completed. Basic logic as well as single, double, triple naked pairs are all you need to know.

4/5 stars

Great app

A very nice way to play sudoku. It's clean and no ads!

My only complaint: if you type in an incorrect number it highlights the number red. If it is correct it is black. I wish it wouldn't tell me right away. I like to figure it out if I mess up.

Other than that it's absolutely the best free sudoku.

5/5 stars
