Rubik's Magic: Master Edition
Rubik's Magic: Master Edition (most commonly known as Master Magic) is a mechanical puzzle invented by the Hungarian sculptor and professor of architecture Ernő Rubik and first manufactured by Matchbox in 1987. It is a modification from the Rubik's Magic first published in 1980. The difference is that Master Magic consists of 12 square tiles, while Rubik's magic has only 8 tiles 
In Poland, non official version of Rubic's Magic with 16 tiles was introduced in 1990.
The goal of the game is the same as for Rubik's Magic, which is to fold the puzzle from a 2 × 6 rectangular shape into a W-like shape with a certain tiles arrangement. Initially, the front side shows a set of 5 linked rings. After solved, the puzzle is in the shape of a W letter, and shows 5 unlinked rings on the back side of the previous initial state.
The puzzle has 12 panels interconnected with nylon wires. In a 2 × 6 rectangular shape, measuring approximately 4.25 inches (10.5 cm) by 13 inches (32 cm).
As a puzzle, the Master Edition is actually simpler than the original Rubik's Magic. It offers more degrees of freedom (more hinges), allowing you to work on one part, mostly ignoring the other parts.
