He left many minds boggled when he asked the web to find the panda among the snowman and now Gergely Dudás is back with another tricky brainteaser.
Dudolf, as he is known to his fans, shared a new brainteaser on Facebook, asking users to spot a single lollipop among dozens of ice creams.
With a sea of the frozen treats, all in very similar shades, it is almost impossible to spot the lolly.
More than 4,000 infuriated fans have attempted to hunt down the sweetie – but can YOU spot it?

Hungarian artist Dudolf has challenged the web to spot the lollipop among a colourful crowd of ice creams
Eagle-eyed players should be able to spot the smiling lollipop towards the top right hand corner of the picture.
A number of people claimed they found the lollipop quickly but enjoyed the puzzle.
One person said: ‘Took 2 second to find the lollipop but spent 3mins laughing at the horrified 2 cones and the one licking them’
Another wrote: ‘The green ice-cream near the left top corner and with a big smiley face has caught my attention…I can’t take my eyes from it to spot the lollipop’
Eagle-eyed players should be able to spot the cheeky treat towards the top right hand corner
The Hungarian cartoonist is behind some of the internet’s best-loved visual puzzles.
He also released a special Easter puzzle for fans.
Somewhere in this vibrant flower patch there is a single bee buzzing around for honey – but only the most eagle-eyed players will be able to pick it out.
Last year’s Easter offering, a single egg hidden in a busy garden, was challenging, but this one is undoubtedly more difficult.
For those looking for a clue, the yellow bee is flying between two blooms of the same colour.
Dozens of fans commented to say how tricky they had found the puzzle after Dudolf shared it on his Facebook page.

Another agreed: ‘I had to put my glasses on for this one ~ but I found it!’
Dudas 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.
At Christmas Dudas released a new book, Bear’s Merry Book of Hidden Things, which uses colourful illustrations and seek-and-find puzzles to tell the story of a bear getting ready for a Christmas party.
While the title is aimed at children, the puzzles are tricky enough that they will keep parents entertained, too.
