A Christmas-themed game to spot a panda hiding among 200 snowmen is blowing up the internet.
Some deny the puzzle even has a solution, while others claim to have found the crafty panda within seconds.
The post, by young Hungarian artist and cartoonist Gergely Dudás, has been shared over 110,000 times on Facebook.
Dudás, who posts under the pseudonym Dudolf, says he has been taken aback by the popularity of the ‘Where’s Wally’ style puzzle.
A second puzzle to find a solitary cartoon cat among a flock of owls is getting similar attention.
Did you find them?
