((wikipedia |)) Sudoku is a plug-in to generate and solve Number Place puzzles, so called Sudokus.

A Sudoku puzzle consists of 9 x 9 cells subdivided into 9 regions with 3 x 3 cells. The rules are simple. In each row, column and region must be the numbers 1 to 9 so far. Some numbers are given at the beginning. These cells are cyan background. The aim of the puzzle is to find the missing numbers. There is only one solution to a Sudoku puzzle.

The Sudoku puzzles are generated on the fly. The number of givens can be selected in the settings of the plug-ins to a minimum of 26 The generation of puzzles with less than 26 givens takes too long. By default, the cells with given numbers symmetrically. But this can be changed in the settings.

To solve difficult Sudoku puzzles, there are some hints. Defective cells are red cells with ambiguous figures, and magenta. This assistance can be switched off in the settings. Use the green button cells can be marked. A selected cell has a green background. With the yellow key, the cursor to the next free cell with minimal possible numbers is set. The red button is the next possible number for the current cell.

Each time the plug-ins from the main menu the same puzzle appears. A new puzzle is only generated when the VDR is started or when the appropriate command is selected in the command menu. The command menu is opened with the blue button.

In the command menu you can load and save puzzles from / sudoku-list file. This file is located in the plugins folder inside the configuration directory of the VDR. If the configuration directory is not explicitly set, the video directory is used (eg / video0/plugins/sudoku/sudoku-list).

The sudoku-list file contains lines with a sudoku dump and an optional description. The sudoku dump must in the first position of the line start. The separator between sudoku dump and description is a space. Everything after the first space is considered as the description.

A Sudoku dump is made up of three parts. The first part contains only the givens, the second part all of the numbers set so far (including the default) and the third part of the selected cells. The parts are separated by a colon. All except the first part is optional. The parts are strings of 81 digits, or underscores. An underscore is interpreted as zero. All other characters are ignored with the exception of colons and spaces that will end the string They can be used to structure the dump, for example, plus sign after each 9 digits / under lines.
