They often say that a picture is worth a thousand words but sometimes, they are worth more than we know. That is the case with picture puzzles, which are items that can put our mental abilities to the test.

This is one of the most unique picture puzzles we have seen in a long time. The two pictures may look identical but there is actually a subtle difference and your job is to find it.

People have been trying to find this for a very long time so to make it even more challenging, we are only allowing 30 seconds for you to find the difference. Are you up for the challenge?

It takes a very keen eye to see the difference between these two pictures. Most people overlook it because they don’t tend to look at the details.

That is why this is more than just a test to see what kind of abilities you have. It will also let you know if you can spot the difference when it is very subtle.

Some people find that it helps to look from top to bottom and then scan the picture and every detail that is in it. Considering the complexity of the image, however, it is highly unlikely that you will find the difference in 30 seconds using this method.

Are you ready to know the difference? We are about to tell you, so make sure you have given it your best try.

The answer is…

There is a difference in the sash over the book! We told you it was subtle. We have it circled for you below.
