Sudoku

Introduction

Sudoku in Rockbox is implemented as both a plugin and a viewer.

When you start Sudoku in plugin mode from the 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 Generate menu option.

You can also use Sudoku as a "viewer" for playing pre-generated Sudoku games. Sudoku games are stored (one game per file) in text files with the .ss extension. You then browse these games using the normal file browser, and open the file to launch Sudoku.

Some pre-generated .ss files can be downloaded from the Simple Sudoku home page. Specifically, the Advanced Puzzle Packs 1 and 2 located near the bottom of that page.

You can also create and save your own grids using the "New" menu option.Press the menu button 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 now 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 NOT saved when saving the game
