10.1.23. Sudoku
Figure 10.20.: Sudoku
Sudoku in Rockbox is implemented as both a plugin and a viewer. When you start
Sudoku in plugin mode from the B
ROWSE
P
LUGINS
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
G
ENERATE
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
.ss
extension (see
links below). You then browse these games using the normal F
ILE
B
ROWSER
, and open
the file to launch Sudoku.
You can create and save your own grids under the N
EW
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
.ss
extension (e.g.
/sudoku/new.ss
).
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 scratch-
pad button, the number will then be added on the left. The column is stored seperatly
for every cell on the board. These are
NOT
saved when saving the game.
