The Rubik's Revenge (aka the Master Cube) has 4x4x4 blocks, making it harder to solve than the original Rubik's Cube. This puzzle was released in 1981 and was actually invented not by professor Rubik himself but by Péter Sebestény.

The most common algorithm for solving the Rubik's Revenge is called the "reduction" method. As implied by its name, this algorithm focuses on solving the 2x2 center pieces and 2x1 edge pieces first - thus "reducing" the problem to a 3x3x3 puzzle, which can be solved exactly like a regular 3x3x3 cube (Except for two parity cases that require further algorithms).

This puzzle has more parts than the Rubik's Cube, thus many more possible permutations. The number of possible permutations of the Rubik's Revenge is over 7.4x10^{45}. The Current world record for solving it is 16.79 seconds, and it was set by Max Park from the USA at the Bay Area Speedcubin' 29 PM 2022 competition.

WOW I could never solve a 3 by 3 and this really helped! the way I used to solve rubik's cube by ripping off the stickers and breaking it then putting it back together

Rubiks cube noob

This is hard

Totallynotdream

Totally fantastic

it helped a lot

Awesome! It’s also nice for a small challenge sometimes

Realy fantastic

Mars Uy

I can solve a 4 by 4 rubik's cube by myself

The Cube Master

WOW I LOVE IT

Terfy

I literally solved it by solving a 3 by 3 with a few tweaks

Dayan Rang

my friend had one of these and this is a good simulator to practice 4x4

Nabikunyoi

Had this cube as a kid and couldn't solve it

Cube buxer

Its a great simulator for practicing 4x4

Random guy

I made a Checker Board pattern :D

Cool, you can make 2x2 patterns on the 4x4, but NOT vice versa.

pengch

I solved it in 7 and half minutes this is amazing

Soph

Hard for me but It's okay i still like it-

Gabriella Byrnes

This kinda easy to solve 1 side but others I cannot solve it

Pro Cuber

I have all cubes + megamix (but not 7x7x7 or 8x8x8)
