This Sudoku game for android was developed by Tobias Eckert from Androidcan.com
The game makes use of the unique Android user interface. It works as well in Touch Screen mode as with a standard numeric telephone key-board. The Android always-connected feature is used to seamlessly integrate the AndroidCan Sudoku challenge with the emergin Androidcan web site.
The game does not need a big instruction manual. Just select "?/Tutorial" from the menu to get an overview of how the intuitive user interface works. The game features 30 pre-installed Sudokus. Once those are solved, the user has the possibility to create an unlimited number of Sudokus in Free Play mode. You can't access this feature right away though. The pre-installed Sudokus need to be unlocked and solved first.
