A ‘7’ in this image has decided to rebel and become a letter – can you find the traitor?

Nothing gets our brains working quite like a good riddle/brain teaser. Obviously it’s important that we don’t allow our brains to switch off, so to that end we like to encourage others to give it some beneficial exercise every now and again.

With that in mind, we’ve found a picture that’s both strange and difficult to make sense of. Today’s dilemma is to identify what is out of place in the image below. The issue? Well, you’ll need visual aptitude and the ability to work quickly and efficiently.

The focal point of this particular brain teaser is the number ‘7’. You need to carefully examine the image we’re about to present to you, because in a few short seconds you’re going to have to figure out which one has grown an extra limb (or a new line, as it were).

It takes a degree of visual sharpness to notice the rebellious seven hiding amongst the other sevens, but eventually you’ll be able to spot it.

Now, ready yourself, take a deep breath and peel your eyes carefully. Let us know how long it takes you to solve the puzzle in the shortest amount of time.

How did it go? Do let us know in the comments box! Did you find the wrong number 7?
