Ok, some of you thought that my previous invention was “nice” or even “very cool”, but some also thought that it was “really easy” and “not a challenge”.

So I have to keep inventing new stuff. I quickly checked the web and couldn’t find this variation. If you’ve already seen it, please let me know.

For the first time on this site, I’m presenting you with a HYPER Sudoku (aka Windoku) puzzle. There are 4 extra nonets which must obey the good old rules of Sudoku. Since many other authors are already creating this, I’ve prepared something special for you. A Hyper (Windoku) Samurai Sudoku puzzle. Since Samurai are 5-in-1 Sudoku and in each Sudoku you have 4 extra nonets, in this one you have 20 extra nonets to take care of!

Have fun and let me know what you think!
