Rubik's Clock

This game is played using a box, which has nine clocks on both sides. There are four wheels at the corners of the box, which can be turned to rotate the clocks.

Four push buttons are available to to control which clocks rotate. The clocks on both sides are intelligently connected. This means that rotating clocks on one side may rotate several clocks on the other side. The goal is to set all clocks to twelve o'clock.
