Seven hours sounds just about right for the average puzzle enthusiast to solve a standard 3x3x3 Rubik's Cube. But Youtuber RedKB isn't your average puzzle enthusiast. Instead of tackling a 3x3x3 cube, he solves this incredibly complex 17x17x17 cube designed by Oskar Van Deventer. In the end it took him about seven-and-a-half hours to get all the coloured sides put back in order, and you can check out a timelapse of the entire process below.
To put things in perspective, there are 66.9 quinquagintatrecentillion possible ways to scramble a 17x17x17 Rubik's Cube. That's 6.69 * 10^1054, written out there would be over a thousand zeroes! And if you find you've got a lot of free time on your hands to kill today, RedKB has also posted his full seven-and-a-half hour solve to YouTube, which we can assure you is utterly thrilling.
