Confetto Box (RF-39) was developed systematically. A different maze was madeon the same structure. The top links with the 4 sides. The bottom is thelid. The 4 side plates work with each other. The movement is only openingand closing, with no relation between the opposite sides, and only the topand sides link. In order to achieve these movements, I arrived at thesedesigns.

This is a kind of “Branch Type” puzzle. This is an advanced version of “Branch Type”. This puzzle has the third highest number of steps at 23, andextracted number of side movements is 9. The movement route is likesomething that has its timing out of sync. It looks complex and interesting.It was a surprise to be able to design an advanced version of “BranchType”.
