Free printable sudoku – now even krazier
The majority of folks visiting this website for puzzles prefer the easy and intermediate puzzles. However, there is a small but vocal contingent campaigning for hard puzzles. Yes, even harder than my “super toughs”. So, I’ve added a 6th difficulty level, insane, which includes the puzzles that I omit from the super-tough class as basically being “unsolveable”. I’m not even going to pretend that you can use basic logic to solve these ones. It’s guesswork and trial-and-error all the way.
Hey masochists! You can get your insane puzzles right here.
Enjoy!
