A five-layered variant of the C-10 puzzle. This is a cylindric Square-0.5 puzzle. Unlike C-10 it has five layers and does not behave bandaged.

After he had managed to create the C-10 puzzle, the inventor wanted to go even further and added two additional layers resulting in this five-layered prism. The puzzle's name is still an allusion to the carbon isotope although this one is meant to celebrate the inventor's age at the time of creation.

According to the inventor, this puzzle is working decent although not as well as the smaller version of it. The additional layers add a new difficulty to the well-known concept although it is still not obvious if this has to be seen as a bandaged (2x2x5) cuboid or a Square-1 variant.
