四阶扭计骰（英语：Rubik's Revenge），为4×4×4的立方体结构。发明人为彼得·塞波斯坦尼（Peter Sebesteny），四阶魔方起初称作为Sebesteny魔方，后来在生产前最终定名为“Rubik's Revenge”来吸引魔方爱好者，因为这个名字在英语中有复仇的意思。

和三阶魔方不同的是，四阶魔方没有每面不动的中心方块，所以四阶魔方的复原方法与众不同，要先复原中心块和成对的边块形成一个大号的三阶魔方，再用原来的方法复原。

一家名叫东贤（East Sheen）的公司发明了一种新的复原方法：使用三阶魔方的方法先复原边块和角块，再复原中心块。

The Rubik's Revenge (also known as the Master Cube) is a 4×4×4 version of Rubik's Cube. It was released in 1981. Invented by Péter Sebestény, the Rubik's Revenge was nearly called the Sebestény Cube until a somewhat last-minute decision changed the puzzle's name to attract fans of the original Rubik's Cube. Unlike the original puzzle (and the 5×5×5 cube), it has no fixed facets: the centre facets (four per face) are free to move to different positions.
