|
|
Sudoku in Rockbox is implemented as both a plugin and a viewer.
|
|
When you start Sudoku in plugin mode from the \setting{Browse Plugins} menu, a random
|
|
game will be generated automatically, and an estimate of its difficulty
|
|
(very easy, easy, medium, hard or fiendish) will be displayed on the screen.
|
|
New games can be generated from the \setting{Generate} menu option.
|
|
|
|
When you use Sudoku as a viewer for playing pre-generated Sudoku games.
|
|
You need sudoku games stored (one game per file) in text files with the
|
|
\fname{.ss} extension (see links below). You then browse these games using the
|
|
normal \setting{File Browser}, and open the file to launch Sudoku.
|
|
|
|
You can create and save your own grids under the \setting{New} menu option.
|
|
Press the menu button when you have finished and enter the full path
|
|
to save to including the \fname{.ss} extension (e.g. \fname{/sudoku/new.ss}).
|
|
|
|
\subsubsection{The thing on the left (AKA the scratchpad)}
|
|
When you play sudoku on paper most people like to mark numbers in
|
|
cells that are possible candidates for the cells.
|
|
This can be done with the column on the left. Change the number
|
|
under the cursor to a number which might be valid and press the scratchpad
|
|
button, the number will then be added on the left.
|
|
The column is stored seperatly for every cell on the board.
|
|
These are \emph{NOT} saved when saving the game.
