Test your ability to spot patterns and see if you can beat the clock and open the padlock in time.
You'll be shown a series of pentagons, each containing a triangle and circle, but the first one in the sequence is missing. Can you work out which is the correct pentagon to fill the space, and unlock the padlock?
It may help to have a pencil and paper to jot down your thoughts. You have 90 seconds to unlock the padlock, although you can have more than one go. Good luck!
