In each set of busy scenes, look closely and see if you can spot five differences between the two. Click each difference that you see. If you canât seem to find all five, click on one of the magnifying glasses to get a little extra help. But, youâll only get four clues per game, and if you click on areas where there are no matches, youâll lose time. When time runs out, youâll start over and you can try again. Good luck!
