About

Atomic Chaos (a.k.a. Kaos, or Brain Drain) is a tricky puzzle consisting of 6 tubes of different lengths arranged in a circle. In the starting position, all tubes are filled exactly halfway with balls of the same colour. The shortest tube has only one black ball, the longest six red ones. All the tubes are split in half, and you can rotate one half of the puzzle so that the tubes in one half of the puzzle are matched against tubes of different lengths in the other half. The patent was filed by Christoph Hausammann on 23 July 1990, and finally granted on 5 January 1993, US 5,176,382. The German edition of this puzzle is called Kaos.
