Diansheng Super Square Star
Diansheng Super Square Star may look like a toy, but do not let looks fool you. This is an advanced puzzle that is hard to solve and suits those who are looking for unique puzzles with new challenges. The circle in the middle can be rotated separately from the other pieces and can be rough to turn, so we recommend that you lubricate it with, for example, Luboss Drive for more comfortable handling.
