I Completed it in 40 minutes, but I put this down to some of the pieces being behind the almost complete jigsaw, which didn’t help me identify the missing pieces I required
I give up. As frustrating as watching the real thing - after 30 minutes, there are still gaps in the defence.
I found the Nigel Spackman jigsaw really difficult. The whole thing seemed to have fallen to pieces, and I kept trying to put the square pieces in the round holes.
