9 digits - sudoku variations for iPhone/iPod Touch

Postby 4ive » Thu Jul 21, 2011 7:14 pm


we have just release our first iPhone game - and its another sudoku game...

I like all sort of logic puzzles and love to figure out algorithms for solving and creating such puzzles. We have created some Java Mobile games years ago (see http://5ud0ku.de - featuring Sudoku, Kakuro and Hitori)
When I bought an iPhone I wanted to play my number games again... Even if there are a lot of Sudoku apps in the app store out there, none of them has met my expectations. So my partner Marcus and I started to spend our spare time to write our own game featuring four types of puzzles based on sudokus and are now sharing it on the App Store.

Our game - 9 digits - comes with Sudokus, Killer Sudokus, X-Sudokus and MathDokus.
It has a nice hint-system which aims to teach you the solving techniques and we made the user interface simple for entering a digit or pencil marks. We tried to give 9 digits an original look to make it stand out from the crowd.

So you get an idea, we made a short video on youtube (http://www.youtube.com/watch?v=qfi7vyoUOEM) which just shows the gameplay and there is a website http://9digits.de

9 digits is a free app, but we added puzzle packs as in-app purchase options.

We love our litte game and maybe you like it as well…
