|
|
Sudoku in Rockbox can act as both a plugin and a viewer.
|
|
When starting Sudoku 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 ``playing'' an existing Sudoku game file from Rockbox' file browser
|
|
the plugin is invoked as viewer. The selected Sudoku will get loaded and you
|
|
can start solving it. The sudoku games need to be stored as text
|
|
files with the extension \fname{.ss} as single file per game.
|
|
|
|
You can create and save your own grids under the \setting{New} menu option.
|
|
Enter the menu (as described in the key table below) 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 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 scratchpad, shown as separate column.
|
|
Change the number under the cursor to the number you want to put on the
|
|
scratchpad and press the scratchpad button, the number will then be added.
|
|
If the number was already on the scratchpad it will get removed again.
|
|
The column is stored separately for every cell on the board. The stored values
|
|
can be displayed inline as small dots by enabling the \setting{Show Markings}
|
|
settings.
|
|
\note{The scratchpad is \emph{not} saved when saving the game.}
