The Son-Mum 4x4 V1 is a new cube from mf8 that features the same types of moves as previous puzzles in the Son-Mum line. Turing one or both of the middle slice layers by 45° results in new turns that you may not expect. This makes this puzzle interesting and a new challenge for people who like unexpected movement in their cubic puzzles.
