For some people, doing a jigsaw should be about time to relax, unwind and doing something fun and engaging. But for other people, doing a jigsaw puzzle is all about the "challenge". And in some cases, the bigger the challenge, the greater the achievement.
It is exactly with this in mind that we have collected a range of jigsaw puzzles on this page, which we suggest might be more challenging than most jigsaw puzzles. The questions is, are you brave enough to take on the CHALLENGE?
