About
Beat 30 levels in 3 difficulties and become a true sudoku master.
I really hope you enjoy playing this game. I created this game because I personally like solving sudokus. Then in the progress I decided to create the whole game only in AS3 - no library, no graphics.
Therefore, you might find the design very simple. It also resulted in many additional lines of code but cut down the size of the game to 12kb.

Update
1.01
Level 2 on Easy was unsolveable so I removed it and replaced it with a new level. Have you saved any data from the old level you'll experience a messed up level - you will then have to press "clear level" and then "save" afterwards.
A minor bug solved.
You can now store 8 numbers in every note field. I figured that 9 numbers might have been overkill.

Instructions
In-game you can find some pretty good instructions. The game auto-saves when you change sudoku or return to the menu but I have added a save button anyway so that you can save before you close the game.
You can move around with the arrow keys and turn the note-function on and off by pressing SHIFT.
