I'd like to apologize to all of you because I have to cancel today's variant Sudoku Extraregion.
The design wasn't choosen well and a lot of players didn't see it correct.
You can play it but this day won't be counted into monthly standings!

Please let me know if the change of desing is good for you. I've make it more deep (20%).

Thank you for understanding!
