Combination Cubes

The contestant is presented with nine giant cubes. These must be assembled into a three-by-three square to display a four digit combination. Although there were six possible ways of arranging the cubes (each side was a different colour, and so placing those colours face up would give a different answer) two pieces were placed side-by-side, yellow side up, giving the contestant one massive clue, and essentially leaving them a nine piece jigsaw to complete in the three minutes alloted.
