Strange things are happening around the world. Someone is taking pictures in different places and challenging people to find the differences from the originals as fast as possible. Detective Rachel Holmes is on the case, and she needs your help.
Carefully compare the two pictures and tap every difference you find. You are competing against other detectives, so try to spot all the differences before your opponent does. Use your detective tools to collect clues when you get stuck, and collect valuable rewards along the way. Levels of varying difficulty keep the challenge fresh.
