Juggling While Solving the Rubik's Cube


Juggling While Solving the Rubik’s Cube

Rubik’s Cube lovers are always on the hunt for new and exciting ways to cube. Some of the most popular, WCA endorsed events include solving the cube one-handed, with feet, or blindfolded. One cool specialty hobby is solving the cube while juggling. In this article, we take a closer look at some records that were set juggling Rubik’s Cubes while solving them. 

There are a few techniques for solving while juggling such as juggling two balls with one hand and solving a cube with the other or solving 3 Rubik’s cubes individually while juggling them.

David Calvo

Youtube is full of videos where people show off their skills. One of the first “Youcube” juggling videos was posted in 2011, and has since racked up over a million views.  David juggles two solved cubes while he solves the third one handed in this solve David Calvo’s Three Cube Juggle.

Ravi Fernando

Ravi Fernando is another cubing juggler. He was the first cuber who solved three Rubik’s Cubes individually while juggling them. He accomplished this stunt in six minutes. Although there were many skeptics of this feat, speedsolvers all back the solve and the video is considered genuine. Since being posted in 2013, the video has 1.8 million views. 


A viral video by “Youcuber” Leo Weston VFX was posted in 2016, where he solves three Rubik’s Cubes individually while juggling them. Immediately after being uploaded it was pointed out to be a fake. He performed the feat in under 20 seconds, astonishing audiences everywhere. However, viewers in the comments were quick to point out that this is almost certainly physically impossible. The world record for solving a Rubik’s Cube one handed is 6.88 seconds. At that speed, it would take 20.64 seconds to solve 3 cubes. But Leo solves 3 in under 20 seconds while juggling. 

Media outlets The Telegraph, Sploid, Metro and Mirror all reported on this feat, expressing amazement in the accomplishment mingled with doubt of its plausibility. Online speedsolving forums analyzed the video, trying to figure out how it was faked. One popular, yet disproved theory was that this video was reversed. Others argued that Leo had memorized a solution with very few moves, but it was quickly pointed out that together with the orientation of the caught cubes and recall needed for each move this would also prove to be very impressive. 

The truth was brought to light when someone pointed out that Leo was standing behind a “Rushes” banner, a UK digital FX company. One week after the video Leo uploaded a How it was actually done video, demonstrating that it was an incredibly well done video edit. He writes in the description “The skill on display here is expertise in seamless digital effects work — not physical solving of the Rubik’s cubes.”

Nonetheless, this video was well done and incredibly entertaining. The video received attention from many famous cubers such as  YouTuber RedKB, UberCuber, and even the famous puzzle designer Tony Fisher. 

Guinness World Record

The fastest officially recorded time to solve three Rubik’s cubes while juggling is 5 mins 2.43 sec. This was achieved by Que Jianyu (China), on the set of ‘La Notte dei Record’, in Rome, Italy, on 17 November 2018. He beat his previous record of 5 minutes and 6.61 seconds, which he set in 2017.
