     You have 27 cubes, 9 white, 9 red and 9 blue. The
problem is to put themtogether to form a big cube (3x3x3)
such that no row, column  or diagonal of three cubes is  a)
all the same colour b) all different colours. The diagonals
include the slant diagonals, i.e. those including the
central cube in the big-cube. This is a much harder puzzle
than 27ortho.
