The artist behind some of the internet's best-loved visual puzzles has shared a riddle that is guaranteed to leave people cross-eyed. Hungarian cartoonist Gergely Dudas, better known as Rudolf, took to his popular Facebook page over the weekend to mark the end of the summer with a new quiz. Rudolf, who boasts 300,000 likes and followers collectively, shared two images of animals enjoying ice cream in a park, revealing that there were seven subtle differences between the drawings. Challenging followers to find the changes, he said: 'Summer is almost over... Have another ice-cream while it's still hot outside! Can You find 7 differences?'
The original picture seen on the left shows two bears giving out ice cream from a stand, as a deer plays football with a bunny and a hedgehog enjoys a snack. Meanwhile, two baby penguins play on a mat while a turtle sports sunglasses on his shell as the animals enjoy a sunny day out. The hand-drawn image even shows a few of the animals teasing the followers, holding up a sign which reads: 'Can you find 7 differences?'. However, in the right-hand picture, seven subtle adjustments have been made, visible only to the eagle-eyed and revealed in the picture below.
And followers quickly flocked to the post to share their reaction to the clever puzzle, which stacked up 500 likes and 200 shares and comments. Praising the quiz, one wrote: 'It's so satisfying to find all of them on your own!'. and another added: 'I love this!'.' Took a bit.... found them!', one said while another added: 'The colour ones always mess me up'.
Sharing his odd method, one follower wrote: 'Oh jeez! Didn't expect it to work, but crossing eyes steadily enough, you're able to overlap the two picture and get it quicker.' In July Gergely shared a similar puzzle to mark International Tiger Day, challenging followers to find the odd one out.'Which tiger doesn't have a pair?' he asked, uploading the snap which quickly garnered over 500 likes.
And while some managed to solve the problem, others fell at the first stumbling block struggling to understand the task. One joked: 'A pair of what? I may just need more coffee, but I don’t understand.' And another explained: 'He should have said which tiger does not have a twin. I finally figured that out.'
Giving a further clue, one wrote: 'You have to match them up in pairs like the old fashion match game,' to which one said: 'I think it's based on stripes on the head'.Another added: 'I don't know if I'm supposed to be happy that I found the one or sad knowing he/she doesn't have a partner! 'Dudas first became an online sensation after his deceptively difficult seek-and-find puzzle featuring a panda hidden among a group of snowmen swept the internet in December 2015. He now produces puzzles for most major holidays - and delights followers by posting random editions throughout the year.
