If you can spot it within the allocated time, congratulations, you have 20/20 vision.

Why don’t you really up the ante and share the puzzle with your friends and family to see who can get it quicker.

Don’t panic if you’ve not managed it. If you need a hint look towards the right of the picture.

Need another clue? It’s on the third row, and if you still can’t spot it, scroll down for the answer.

Visual tests or brainteasers – like this one – are one way that you can check how your mental and observational agility fares against others.


    Puzzles are one of the best ways to stimulate the brain and give the mind some much-needed exercise. There are three different types of brainteasers: observational, analytical, and mathematical.

    Mathematical brainteasers ask the user to solve a maths-based question as quickly as possible whilst analytical brainteasers come in the form of a riddle or word-based puzzle.

    If you enjoy a good brainteaser then has a range of puzzles for you each day and they can all be found here.
