Rubik's Clock

Giới thiệu

This puzzle consists of a disk with 9 small clocks on each side arranged in a square. The four corner clocks can be twisted (the front and back corner clocks are connected). In between the clocks are four buttons. By pushing then up or down, the front or back clocks adjacent to it are connected to the corner clocks so that they will be turned when the corners are turned. The aim of the puzzle is to set all clocks to 12 o'clock. The pictures above show the original Rubik's Clock on the left, and an imitation version on the right. That imitation is called the Magic Compass, since it has points of the compass written around each face. It still has 12 positions for each 'compass' even though 8 or 16 positions would be more logical, since the mechanism is a direct copy of the original. It is a little known fact that the clock was actually not invented by Rubik himself but by Christopher Wiggs and Christopher Taylor. They previously invented the Orb. Rubik's Clock was granted a patent on 26 September 1989, US 4,869,506. If your browser supports JavaScript, then you can play Rubik's Clock by clicking the link below:
