Announcement text given by the package's contributor: - - - ---------------------------------------------------------------------- Sudoku is an environment for typesetting sudoku grids.
A sudoku puzzle is a 9x9 grid where some of the squares in the grid contain numbers. The rules are simple: every column can only contain the digits 1 to 9, every row can only contain the digits 1 to 9 and every 3x3 box can only contain the digits 1 to 9.
More information, including help and example puzzles, can be found at http://www.sudoku.org.uk. This site also has blank sudoku grids (or worksheets), but you will not need to print them from there if you have this package installed. - - - ----------------------------------------------------------------------
