A really interesting cluebox puzzle from iDVenture. It combines both traditional jigsaw with some fun hidden mechanisms to create a really unique puzzling experience.
There are 200 pieces to put together with four different jigsaws to complete, one on each side of the pyramid. Once you've pieced them together you can activate the mechanisms leading you towards unlocking the box.
A suggested solution time is 90 - 120 minutes and once you have opened the box there is a small storage space inside.
