MF8 Son-Mum 4×4 V1


MF8 Son-Mum 4×4 V1 is a truly unique puzzle. At first glance it looks like a mix of a 4×4 and a 6×6, but that’s not the case! On this puzzle, you can do a 45 degree turn to shuffle the pieces in the center of the cube. The puzzle will then also change shape and you will have a real challenge ahead of you. Note that the puzzle is sluggish compared to many other models.
