4x4 rubik's cube
The 4×4 version of the Rubik's Cube.
Although it was developed by Péter Sebestény, not Ernö Rubik, it was named "Rubik's Revenge" upon its release in 1981 in order to capitalize on its resemblance to the original 3×3 puzzle, which was still wildly popular at the time.
Later known in Rubik's brand marketing as the Rubik's Master. Speedcubers identify this simply as a 4×4.
