Rubik's Cube 4x4: Revenge

The game "Rubik's Cube 4x4: Revenge" (also known as "Master Cube") is a more challenging version of the legendary puzzle that will challenge even experienced solvers! This puzzle is shaped like a 4×4×4 cube, making it significantly harder to solve than the original 3×3 Rubik’s Cube. In addition to the 8 familiar corner pieces, there are twice as many edge pieces and a full 4 center pieces on each of the six faces, instead of just one in the classic cube. The most common solving method is called the reduction method—first, you need to assemble the 2×2 center blocks and 2×1 edges on each face, and then, treating them as separate elements, simplify the problem to a standard 3×3×3 cube, which can be solved using standard algorithms. An important feature: in cubes with an even number of elements, there are no fixed centers, so the center blocks must not only match in color but also be located on the correct faces of the cube. This puzzle has an incredible number of possible combinations—over 7.4×10⁴⁵ permutations, which is millions of times more than the classic Rubik’s Cube. Playing is very simple and convenient: the game starts with the cube already solved. You have a “Shuffle” button to automatically randomize the puzzle, a “Reset” button to start over, and the option to expand the game to full screen for a better view. Just rotate the cube’s faces with your mouse or finger on the screen, rotating the layers horizontally and vertically, trying to match all the colors on each side. If you get stuck or confused by the algorithms—press reset and start the solve from scratch! This is the official speedcubing puzzle, and the world’s best players solve it in under 20 seconds. Can you set or beat your personal record?
