Wisdom is the hardest version, challenging your limit.

It is spherical sliding puzzle with 6 rotatable discs and each of them has the tiles number 1-4 along the edge & 5-8 in the middle.  
 
The white disc has an empty space instead of tile number 8, which allow the tile slide from one disc to another.
