Colour-zone maze

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.

Sorry, this is a Java applet.

The block starts on one end (vertical) and must also finish in this position. The block is not permitted to roll off the grid and, in addition, the block must always
lie entirely within one colour-zone
. Note the block is not displayed in 3D, in effect you see only its shadow.
