With Christmas just days away, what better way to let the festivities begin than by testing out your brain on this tricky festive puzzle? This brainteaser challenges players to spot Rudolph among loads of ordinary reindeer and those who can do so within 14 seconds are said to have 20/20 vision.
It sounds like a simple task with Rudolph’s bright red nose surely standing out, but other flashes of red make him tricky to spot.
Most players’ eyes are immediately drawn to the Santa hats rather than Rudolph’s nose, but eventually they should be able to spot it poking out.
One hint is that those who focus on the right-hand side of the image may need to look elsewhere.
Other advice on how to solve the mystery includes to split the image up into quarters and trawl through each one.
He may even be hidden behind some of his reindeer friends.
For those still struggling, try looking in the top left corner of the image.
