Puzzle for Elliot

Rubik's clock has four turning dials and four up-down pins. The aim is to set all 18 clocks (front and back of puzzle) to point to 12 o'clock.

 

The corner clocks, unlike the other clocks, rotate on both sides of the puzzle together and cannot be operated independently. Thus the puzzle contains only 14 independent clocks.

 

Each pin is arranged such that if it is "in" on one side it is "out" on the other side of the puzzle. The state of each pin determines whether the adjacent corner clock is mechanically connected to the three other adjacent clocks on the front side or on the back side.

 

Since there are 14 independent clocks, with 12 settings each, there are a total of 12^{14}=1,283,918,464,548,864 possible combinations for the clock faces.

 

The world record for a single solve is 2.87 seconds......Wikipedia
