## 25 amazing Rubik's Cube facts

Top lists with similar titles are very popular, especially on YouTube so here's our list about our favorite puzzle. We all know what the Rubik’s Cube is, and we most likely have spent countless hours trying to figure out how to solve the puzzle. Apart from that, what else do you know about it?

## Rubik's Cube firm left puzzled after losing EU trademark

Rubik's Cube was granted the trademark for the shape of the classic puzzle game in 1999, but in 2017 the EU-wide protection was pulled.

The General Court of the European Union on Thursday upheld the decision to remove the multi-coloured cube's trademark protection. The court said: "Given that the essential characteristics of that shape are necessary to obtain the technical result consisting of the rotating capability of that product, that shape could not be registered as an EU trademark."

Rubik's Brand Ltd is able to appeal against the decision one final time.

## The most amazing fact about the Rubik's Cube

How about this: if you mix a Rubik's cube with at least 20 turns, the probability of you ending up with a pattern that has never ever been shuffled before is more than 99.999999%

The number of possible configurations of a Rubik's Cube is over 43 quintillion (43 252 003 274 489 856 000). It means if you gave every living person 6 billion Rubik's cubes, each of them could mix all of their cubes in a way that no cubes on Earth would match.

Let's just say that if you take a Rubik's cube and mix it with 20 turns, you'll NEVER end up with a mixed cube like in the photo above.

And that's for SURE.

## Teen solves 3 Rubik's Cubes simultaneously, sets world record

A teenager who first impressed people by solving three Rubik's cubes while juggling them is now back with another extraordinary feat. Que Jianyu from Xiamen, China, has created a Guinness World Record by solving three Rubik's cubes simultaneously, using his hands and feet.

A video which shows him solving three Rubik's cubes at once has garnered over 40,000 views since it was shared online on Thursday, along with a ton of amazed comments.

According to Guinness World Records, the 13-year-old set the fastest time to solve three Rubik's cubes simultaneously with both hands and feet in just 1 minute 36.39 seconds. He then also went on to break another record by solving a cube while hanging upside down in just 15.84 seconds!

## Largest Rubik's Cube - Guiness world record

The largest Rubik's Cube measures 2.022 m (6 ft 7 in) x 2.022 m (6 ft 7 in) x 2.022 m (6 ft 7 in) and was achieved by Tony Fisher (UK) in Ipswich, UK, on 18 November 2019.

Tony previously achieved this record in 2016 with a cube measuring 1.57 m (5 ft 1.8 in) on each side. When he found out his record had been broken in 2018, he was disappointed at first but also felt flattered that his achievement had encouraged others to be creative and build something of this size.

He received his first Rubik’s Cube in 1980, at the age of 14. He quickly became obsessed with it and began to collect and solve similar puzzles. Since 2010 he has been making puzzles and puzzle videos as a full time job.

The outsized cube took around 330 hours to build. All layers move exactly like a regular-sized Rubik’s cube; however in order to move a vertical side / face you have to flip the whole cube over so the side you want to move is on the top.

The hardest part was getting the tensions correct – the puzzle needs to be loose enough to rotate but if too loose it would come apart, so Tony used large springs and bolts to get it just right.

He estimates the project cost around £2000 overall. He was unsupported throughout and completed the entire project alone.

## Changes to the World Cube Association Regulations

Recently, the World Cube Association Regulations Committee have made changes to the regulations that govern competitive speedcubing which have gone into effect as of the 1st of January 2018. Some of the most notable changes include puzzles with any sort of logo now illegal for blind events, competitors are now allowed to use their hands to inspect the puzzle prior to solving with their feet, and competitors now being allowed to use any “pillowed” puzzle when previously only pillowed 7x7x7 were only legal.

Firstly puzzles with any sort of sticker logo are no longer permitted in blindfolded events. This means if a competitor had a sticker logo of any sort on their puzzle the solve would be counted as DNF (Did Not Finish). This even includes cube stickers with the logo as part of the sticker itself. This has caused Mofangge, the company that produces the Valk 3 and the Valk 3 Power, to respond in a statement offering people who purchased or have purchased a cube to receive an extra cap and an extra white sticker so the cube is legal in blind 3x3 solves. However, on stickerless cubes where the logo is on the actual puzzle this may prove to be a problem.
