mix up and put back to start
This puzzle, designed by Traiphum Prungtaengkit, is a hybrid of face-turning and vertex-turning tetrahedron.We have been prepared this cube for more than half year. This long waiting cube turns smooth, in pillow shape with 8-armed ball core. The goal is to scramble the puzzle and then restore each face to it’s original colour. Thanks for the brilliant design of Traiphum.PS: the 8-armed ball core also fits for modifying the mosaic cube.
