Magic Blocks (Doll House)

Hint 1 of 7:

You almost have three words the way the blocks are set up at the start of
the puzzle.

Hint 2 of 7:

All you really need to do is to exchange the middle and right columns.

Hint 3 of 7:

And the solution only takes a couple of moves.  You need to "isolate" the two
columns and then move them to their proper positions.
