This isn't much of a brain teaser, if a dum-dum like me can get 40 without even trying very hard.

This made me think: do browsers assume square pixels? So that an N by N pixel image will appear square when displayed? Or is that the responsibility of the OS?

41 edit: I amend to 40. I was double counting 1 square

40 - starting with a 4x4 grid, that makes 16+9+4+1 = 30, and adding 8+2 for the inner ones Can someone explain where is the 41th, if there is one?

40 Hope I'm not missing any.

I've got 40 too :-)

41 is the correct answer.
