Title : Mind Challange Classic Series - Sanity

Description :
TLose it!
It couldn't be simpler!
Just 4 pieces...yet infuriatingly challenging!

Sanity consists of four cubes. Each cube has the Dr Wood hallmark in four colours (purple, ochre, blue and green) represented on each face, but in different arrangements.

Your mission: Arrange the four cubes in a row so that all four colors appear on each of the row's four long sides.

Don't forget the bottom! The order of the family members doesn't matter...

Challenge: Can you solve it in one hour?
