Sudoku is probably the most popular number-puzzle. If you read resumes of candidates applying for a new hiring on an executive post in an MNC, you’d find out many of them having a hobby of playing Sudoku. That’s because this game is interesting and addictive but challenging as hell and helps you improve your mental strength. So if you can crack a game of Sudoku in say 10 minutes, you can crack almost any interview you’d sit in. Your IQ would be touching the heights of Einstein. But waiting for a new Sudoku puzzle everyday in the newspaper isn’t a good idea if you really want to sharpen your skills. Want some alternative where you can try a new Sudoku any time of the day? Then I’ve got something for you.


I’m talking about the latest Android app called Sudoku Free that has been developed by Astradia. The app is compatible with all the devices running Android 2.2 or any later version of the OS.

Sudoku Free is one of the most intuitive and streamlined Sudoku application that you’d find in the Play Store. After getting this app in your pocket, you’d forget the Paper Sudoku completely. Right now, we’re used to solving Sudoku on paper because we’re habitual of using a pencil to mark rough numbers on the Sudoku board. Until now, we could not do the same on a phone screen and therefore the experience was terrible. What’s new in Sudoku Free is that you can write down an unsure number in a cell with pencil that’d be written in a small font. You can delete it anytime. Moreover, finding a number is also very easy. So if you’re looking for all the 5’s, just tap it in the bottom and it’d be highlighted everywhere it is.


Sudoku Free offers 5 different levels of difficulty: very easy, easy, medium, hard and extreme. You know your preferences. So there’s ground for everyone to stand on. Moreover, it helps you improve gradually. Even if you’re a beginner, you’d soon be competing against the masters of the game and there’s no exaggeration in that point. Also, each game you play is unique on its own. It’s a different combination every time you press the play button. So even if you have successfully completed 10 hard Sudoku puzzles, you’ll still have to adopt a new strategy for an easy one.


Sudoku is not a graphical game, but the game uses them aptly when required. The color combinations and the overall aesthetics match the theme of the game. So I’d overall say that Sudoku Free is a game that you can play any time. If you have a 5-minute break, start Sudoku Free. Don’t worry about solving it completely. You can continue it later when you have time; it’ll be resumed from the same position where you left it.

If this was not enough, what’s even more incredible is that Sudoku Free is available for free in the Play Store. So don’t forget to check it out!

Pros: 5 different levels of difficulty; apt graphics; unique game each time; pencil marking; easy highlighting; free.

Cons: none.

I give this app 4.5 out of 5 stars.
