Double Dino was suggested by Joan Fons. It combines the operation of two half dino cubes at both ends, and a 1x3x3 floppy cube mechanism in the middle. The idea was to have a 2 dino cubes on top of each other then it could exchange pieces with each other. So the top dino cube just turns at the corner, the same is true for the bottom dino cube. There is also a 1x3x3 at the center. It can be used for the exchange of pieces. The group mechanism isn’t still completely perfect so it takes a bit of friction but you can still swap two pieces and then you can continue turning both sides.
This puzzle toy is super interesting and it would be fun to share and play with friends. Playing this toy is beneficial for improving your puzzle solving skills. This toy could be a very good exercise for the brain.
