bmic has picked up dlkj’s work and improved Sudoku for Wii. Figure out the correct placement of all the numbers!

The puzzle is controlled by moving an on screen cursor. The cursor will wraparound the edges of the puzzle if you try to move past the edge.

The value under the cursor is incremented/decremented to the desired value. Value ‘0’ is shown as a blank cell. Values are wraparound from 0 to 9 as well.

If desired, the user may mark a cell as ‘uncertain’ by pressing the ‘A’ button. This can be toggled off if desired via the same button. ‘uncertain’ cells are marked with a gray background.

The game will check for any incorrect cells (i.e. duplicate numbers in any row, column or 3×3 cell). Any incorrect cells will be highlighted with a red tint.
