Think solving a regular 3x3x3 Rubik’s Cube is hard? Try one that has 17 lines on each side.
The complex cube was designed by Oskar Van Deventer and YouTube user RedKB took on the challenge, recording both time-lapse and regular video of himself solving the puzzle in a mere seven and a half hours.
There are 66.9 quinquagintatrecentillion possible ways to scramble a 17x17x17 Rubik’s Cube, according to Gizmodo. That’s 6.69 * 10^1054, which would have over a thousand zeroes if written out.
