Puck puzzle

The Puck puzzle (Picture Disc, Hungarian: Kép Korong) is a combination puzzle invented in 1980 by Hungarian physicist András Végh. The disc shaped puzzle consists of 2 central pieces - the inner disc - and segments forming a ring around the inner disc. The number of segments is an even number - most commonly six, eight or twelve. The outer ring can be rotated around the central disc, similar to a wheel being rotated around its axis. The two parts of the central disc can also be rotated, together with the attached ring. With these operations the combination of the parts can be changed. The goal of the game is to obtain a specific combination, such as forming a picture or ordering the number on the segments. Several videos on the game and a virtual puzzle can be found online.
