Sudoku Toilet Paper

I personally have not even played Sudoku, but I have noticed that it is
everywhere in all sorts of forms - on handheld games, books, software, and
even key chains. I just wasn’t expecting to discover it printed on toilet paper. But I guess if you’re a Sudoku addict who can’t
bare to be without your favorite brain game, then this will keep you occupied in
even the most trying circumstances.
