Thanks to Randall Munroe.

 

Please forgive me, but isn't this a little obvious? (Top-left is 0, bottom-left is 1).

I was wondering about the same thing. Perhaps that is why its beginner's level?

Anyways, is this all that binary version has to offer? By permutation a max of only 4 sudoku?

 

I'm pulling your legs...

 

Wait'll you try the hexadecimal version

 

Isn't Sudoku(tm) supposed to be a 9x9 matrix? This would be "binary Latin squares," would it not?

It had to be!
