For his latest challenge, McClure put together a revised version of Life: The Great Challenge online, in April, with an additional 1,000 pieces, making it four times the size of the original puzzle. “There are not many changes, except that a logo is seen at a few places and the pieces are larger in size,” he says. McClure will be assembling the puzzle at Select Citywalk, Saket, on Monday, along with 12 winners from an online contest, who solved the puzzle the fastest. “I was amazed to see that Indians were able to solve the puzzle so quickly. It requires a lot of focus and patience which is not always easy,” he adds.

One of his biggest challenges, says McClure, is to sustain peoples interest in the puzzle alive and not bore them even if it’s impossible to solve. “You should be able to discover yourself through the puzzle,” says McClure, who always tests out his new jigsaws with his 23-year-old daughter, Kimberley. “I have solved approximately 90 of his puzzles so far,” she says. McClure is currently busy designing a puzzle of ceremonially decked up Indian elephants and exploring the idea of Indian gods on puzzles. “I like the God with a trunk,” he concludes.

McClure will assemble the puzzle at the Select Citywalk mall atrium, from 11 am to 5pm, everyday till July 8.
