More about this activity
Sudoku is a very demanding game and probably suitable only for older children. This version tries to make it as easy as possible to play. Clashing pieces are immediately revealed. If you get stuck, the smiley will remove any incorrect tiles and place one tile for you - you can do this 5 times and still have your success counted. Patterns are randomly generated but the first one is very easy.
What does "placed with certainty" mean?
As an example, consider a tile and a row. If there is only ONE spot in that row that the tile will go without clashing, then it can be "placed with certainty". The same goes for columns. Tiles that do not meet one of these conditions should NOT be placed yet.

Release Notes
Sudoku can now be played without using the mousepad. This is the scheme:
* o = right click = reset the board
* square or spacebar = new round
* arrow keys will move the selector square
* number keys immediately place a piece if possible
* the zero key will erase a move
If you prefer to use the mousepad, just click on one of the tiles at left.
Sudoku will now work properly without alteration in a non-Sugar environment.
I'm gradually revisiting all my activities. To make it easy to recognise these revisited versions, they will all start at Version number 21. You can easily tell which version you have by pressing the v key - if this gives no response, then you have an older version.
