You must look at two pictures and find the 5 differences in the two pictures. Simply look at each pictured and click on the difference in each picture. For example if one picture has a bird and the other one doesn’t you would click on the bird. The pictures for the most part are identical except for the 5 difference some are easy to spot some are not. Wrong clicks will give you negative points but correct clicks can give you up to 2500 points. Each set of pictures is timed so find all 5 of the differences before time runs out or the game starts over. There are 5 sets of pictures in all.
