Rated at 6 out of 6 in difficulty level.
First of all, let me say I haven't still managed to solve this puzzle (I only bought it last week).
Reputedly one of the most difficult of the collection (although the Cast Nutcase
puzzle could also have a claim to that), the first thing you have to work out is how on earth can the pieces begin to disentangle from each other.
Eventually, a keen eye spots two key features in the puzzle.
I think I may be half way to solving it, but can't tell for sure.
I know there are some youtube videos explaining the solution, but I refuse to look at them on principle.
As ever with this collection, the construction is very sturdy and durable.
If you're looking for something a bit more accessible (which even your children can have a reasonable go at), I'd recommend getting Cast L'Oeuf
