This one was tricky for me too. Look at the top shape in each square. Then look two boxes right and one up .. it's the same figure. If you get to the end of the row, start at the beginning again. If you get to the top of a row, go to the bottom. So the top shape inside the box in question we know is going to be a gray plus sign.
Now for the bottom shape I'm not sure, but I guessed white circle. Anyone know about this?
yeah, that damn Dru knows, but he's playin his "guess the mtn." game...bastard
