So it fell to him to put the Ravensburger 3D Eiffel Tower puzzle through its paces.
The blurb says: "Each jigsaw (there's also Big Ben and the Empire State Building, among others) has 216 pieces that are uniquely curved and hinged meaning no glue required. Using new technology, Ravensburger have been able to create fantastic puzzles to suit everyone from Big Ben to the Empire State Building and adding a new dimension to one of Britain's favorite pastimes. It's for children aged 10 and over - Boy One is 12.
What was good about it? It made a very satisfying, instantly recognisable Eiffel Tower. It kept Boy One busy for a couple of hours and hasn't fallen to bits yet - quite remarkable in this house.
What's not good about it? The instructions frazzled my brain, but I didn't need to worry about it because Boy One understood.
What Boy One said: "The 3D tower thing is OK. It's a bit hard, but it's worth it. The folding pieces are quite fiddly to get in place."
The puzzle costs around £16.
