How to judge the difficulty of a sudoku

  1. Hi,

    I would reccomend www.puzzlemadness.co.uk. They publish 8 daily variations on Sudoku every day including Jigsaw sudoku, Samurai Sudoku and bigger 12*12 and 16*16 grids. If you are a registered user (free) it will track which puzzles you have done and you can save your progress to come back to it the next day (very useful with the bigger puzzles).
