Changes since version 0.1.0: - Fixed compiler warnings with gcc-4.0 (thanks to Ville Skyttä for reporting this). - Added Finnish language texts (thanks to Ville Skyttä). - Added setup option whether or not all cells are unmarked when the puzzle is reset.
This plugin generates Number Place puzzles, so called Sudokus, and let you solve it.
A Sudoku puzzle consists of 9 x 9 cells subdivided into 9 regions with 3 x 3 cells. The rules are simple. There have to be the numbers from 1 to 9 in every row, column and region. In the beginning some numbers are given. These cells are painted with cyan background color. The aim of the puzzle is to find the missing numbers. There is only one solution of a Sudoku puzzle.
