In Rounds 3 and 4, we're going to add a little more challenge. You will still need to select the proper area needed to calculate Q, but you'll only have 5 seconds to mark the area.

Oh, and one other little thing... If you click the wrong tile, you might hit a bomb, which will cost you all points for that particular shape.

On the positive side, if you are fast, you'll get bonus points. You can actually score more than 100% for Round 3 and for Round 4.
