Gnu Sudoku Guide

rules

simply try to fill the empty cells such a way that each character occurs exactly once each row, each column and each square.

tips

to rate a sudoku press the generate button
when there is only one possibility clicking the cell will put it in
instead of clicking you can also use the '=' key
when generating you can interrupt it by pushing the generate button again
you can partly fill in a sudoku and then push the generate button to get a solveable sudoku based upon the initially filled in cells, be warned! doing this on a 5x5 sudoku is a major attack on your patience
you can change the browser that's displaying this page by selecting setup
