rubik's revenge
Rubik's Revenge. The Rubik's Revenge (also known as the Master Cube) is a 4Ã4Ã4 version of Rubik's Cube. It was released in 1981. Invented by PÃ©ter SebestÃ©ny, the Rubik's Revenge was nearly called the SebestÃ©ny Cube until a somewhat last-minute decision changed the puzzle's name to attract fans of the original Rubik's Cube.
