A group of some 15,00 people from the town of Ravensburg in Germany are claiming their place in the Guinness Book of World Records, after assembling what they described as the world's biggest jigsaw puzzle.

The effort was organized by Europe's biggest puzzle maker Ravensburg AG, which put together 1,141,800 pieces of jigsaw in five hours on Monday to form a nearly 6,500-square foot puzzle.

The puzzle was so big it almost covered the whole town square, organizers of the event said.

Organizers said the completed puzzle was bigger than the current record held by Singapore of 212,000 pieces that was completed in 2002.
