Rolling-block colour-zone mazes

A black block, made of two black cubes stuck together, sits on a coloured grid. Your challenge is to roll the black block to its target position, which is marked with a small white square.

There is only one rule... the block must always sit entirely within one colour-zone.

The block starts on one end (vertical) and must also finish vertical. See the diagram on the right to illustrate.

In the applet below you will see a birds-eye view of the board. The block is not displayed in 3D, in effect you see only its shadow.


Roll the 2x1 black block to the white square.
