Loads of you have probably spent a lazy afternoon doing a jigsaw with your family or your mates, but have you ever had a go at a puzzle with more than a million pieces?
That's what thousands of puzzle fans were facing when they got together in the German town of Ravensburg to try to make the world's largest jigsaw.
The giant jigsaw was made by completing thousands of smaller jigsaws which were put together on a massive board in the town square.
They'd only just started here - look how big the board is!
It took more than 15,000 puzzlers five hours to fit 1,141,800 pieces together. They created a puzzle that covers the same amount of space as 25 double decker buses!
Organisers say the finished puzzle is much bigger than the current record set in Singapore six years ago... But officials are still checking to to see if it really is a record-breaker!
