Numbers in (red) are
total solutions possible for that shape.

1 x 6 x 6 (1)
The 1x6x6 with only a single solution and no sub
shapes within makes it the most difficult of the flat
shapes. Quite the beast! You can, however, calculate
which pieces are not used. If you draw a 6x6 grid and
place the 'H' piece at any position it will be obvious
that this piece cannot be used for this shape. Since
the 'H' contains 5 black subcubes and only 2 white
subcubes, other pieces can be calculated as not
working as well since the 1x6x6 has an equal number of
black and white subcubes.
The 'H' piece is really the Key to
the CalmPlex MindBlock puzzle.

1 x 6 x 7 (31)
This 1x6x7 and the 1x6x8 below contain the 1x3x3 at
the corner. They can also be solved using the 1x3x4 in
the corner.
