The supposedly "hardest sudoku in the world".
You can either use a drawing/editing app to edit in the answers, or do it on paper and take a picture of it, to show that you've really done it.
Good luck! The prize for finishing first is bragging rights. xD

But seriously though...good luck, you'll need it xD
ps i'll be trying to complete this too ;p
