The puzzle is made up of 54 curved pieces. Each curved piece is numbered so you know which piece comes next. Each piece also has an arrow showing you if the piece is to be placed next to or above the one before.
The Minion puzzle is aimed at children aged 7 and over. Callum found the puzzle easy to complete and didn't need any help from me. I would say that this puzzle took callum around 10 - 15 minutes to complete. He found it easier when piling up the pieces into sets of 10's. This made the pieces easy to find.
