How to Play Brain Teaser Test

This is a tough little brain teaser. Its in another language but the idea is simple. There are two photos and the object is to try to find the difference in the two photos as fast as possible. They claim a certified genius should be able to find it within the first 15 seconds. It took me almost 3 minutes and only one guy at break solved it in under 15 seconds. Be honest and let us know your time if you beat it.
