Those who have already mastered the simple Rubik’s Cube now have an even bigger challenge on their hands. Made by Coren Puzzle, the world’s biggest Rubik’s Cube measures 22 by 22 squares on each face, meaning you have to line up 484 squares per side—that’s 2904 squares total on the cube.

It can be scrambled in an almost infinite number of ways, so solving it should be a near-impossible task. (It took more than three hours just to turn the cube so that it had a simple checkerboard pattern.)

The puzzle was made with a 3D printer and is about 8 inches wide. If you have eight months or so to spare, you can make your own by following the plans on Thingiverse.
