We're guessing the person who shot the photo for the front cover of "Sudoku Challenge Big 360 Puzzle Book" isn't actually much of a Sudoku fan.

There's a pretty obvious problem with the design, as not-even-that-eagle-eyed users of Imgur have pointed out.

Can you see it?

Scroll down for the big reveal...

Yes, they've written a '5' in a square that already has a '5' in it...

And, no, it's not photoshopped. This is a thing you can actually buy for four of your well-earned pounds.
