Hi
Please tell me, where on internett can I find really hard sudokus? All I find is too easy even if I choose the hardest level. I am not bragging. I just wish to find some that will give me challenges = pleassure.
I am returning to sudoku now after several years "absent". I am looking for some webside with much harder sudokus than the others. I like to write down the sudoku on paper when solving so that I can make notes as I wish. Then all the sudokus I have found on internett becomes too easy/boring.
Best regards
Sverre
