COMPLETING a jigsaw during the summer break is a Philpot family tradition.But this year things got a little out of hand when they decided to tackle the world's biggest puzzle.At 24,000 pieces and more than four metres long, the mega brain-bender, titled Life: The Great Challenge, took the Warrnambool family 69 days to complete.They may be the first Australians to complete the challenge, with no other claims to the honour on the jigsaw's website.Having completed a 9000-piece puzzle before, John Philpot said it wasn't until the 12-kilogram jigsaw arrived that he, his wife Ronda, their son Ben and his wife Stacey realised the huge task."We knew it would be a challenge but once we saw the picture we really wanted it, and we didn't tell (my parents) how big it was," Ben said.Averaging 353 pieces placed per day, family members worked on the puzzle whenever they could, admitting once it was out of the box the jigsaw became an addiction."I'd love to do it again," John said."It's very addictive, I couldn't walk past without doing a piece."The Philpot's will open their home on 17 Verdon Street from 2.30pm to 5.30pm on March 14 for anyone interested in seeing their masterpiece up close.Entry is $5 which will be donated to School's Chaplaincy.
