Puzzly World Records: Redux!

A few years ago, I wrote a post chronicling some of the puzzly world records I’d found while reading the latest edition of the Guinness Book of World Records. Back then, I was surprised to see a two-page spread dedicated to puzzle-centric records.

As I perused this year’s edition of the iconic record-keeping tome, there was a two-page spread dedicated to Rubik’s Cube world records alone. (There were numerous other puzzly records scattered throughout the book as well.)

So, since 2019 is drawing to a close in the next few weeks, why not dedicate one of the last blog posts of 2019 to the most up-to-date puzzly world records I can track down?

Shall we? Let’s shall.

Let’s start with a few Scrabble records.

On January 21, 2012, Singapore’s Toh Weibin amassed the highest score ever recorded in a Scrabble tournament at the Northern Ireland Scrabble Championship in Belfast, scoring 850 points.

January is apparently a good month for word-tile world records, as on January 5, 2015, Lakshan Wanniarachchi set a record for playing the most opponents in Scrabble simultaneously — 40! — in Colombo, Sri Lanka. He defeated 31 of the 40 players in order to qualify for the record.

(So, yeah, you might have more Words with Friends games going at once than Wanniarachchi did, but did you win that many? Probably not.)

Instead of multiple opponents, how about one opponent for 20 hours and 15 minutes?

That’s how long chess masters Ivan Nikolic and Goran Arsovic faced off in Belgrade on February 17, 1989, where they set a world record for the most moves played in a single chess game: 269.

We can stick around Europe for one more puzzly world record, this time in Wageningen, Netherlands, as the Ceres Student Association teamed with Hasbro to create a Monopoly board the size of three-and-a-half tennis courts. Yes, on November 30, 2016, they unveiled a 9,687-square-foot version of the famously frustrating game board.

9,687 square feet? That’s pretty big, I guess. Unless, of course, you’re talking about a world record set in Dubai in the United Arab Emirates, where everything is ludicrously oversized and lavish.

On July 7, 2018, the Dubai Multi Commodities Centre (DMCC) unveiled the world’s largest jigsaw puzzle, a 65,896-square-foot puzzle that commemorated the late Sheikh Zayed.

And speaking of jigsaw puzzles, students at the University of Economics Ho Chi Mihn City in Vietnam set a record by completing the jigsaw puzzle with the most pieces — 551,232 pieces! — on September 24, 2011, breaking the record previously set in Singapore — 212,323 pieces — which had stood since 2002.

According to the Guinness article covering the event:

It took the students 17 hours to first break up the 3,132 sections, each containing 176 pieces, into which the jigsaw puzzle had been divided, and then re-assemble them to create the puzzle.

Seventeen hours of puzzling is ambitious, but what about 24 hours of puzzling?

That’s what Richard Bragg, Daniel Egnor, Amanda Harris, and Ana Ulin — aka Bloody Boris’s Burning Bluelight Brigade — tackled when they set the world record for most escape rooms attended in one day. On October 3, 2018, they visited 22 escape rooms in 24 hours in Moscow, Russia. The team’s success rate was just as impressive; the team escaped all but one of the rooms in the allotted time.

Now that’s an escapade.

Of course, we couldn’t have a world records puzzling post without talking about the Rubik’s Cube.

The official fastest time for solving a standard 3x3x3 Rubik’s Cube is held by Feliks Zemdegs, who set an average time of 5.8 seconds in the 2017 Malaysian Cube Open. (In competition solving, the average time across three different solves comprises your official time.)

The unofficial record for the fastest 3x3x3 solve — meaning it was outside of tournament conditions — was set in China: 3.47 seconds by Du Yesheng.

But that’s only the official size. What about other Cubes? Let’s look at the fastest solves (that I can verify):

  • 7x7x7: 1 min 47.89 sec by Max Park
  • 6x6x6: 1 min 13.82 sec by Max Park
  • 5x5x5: 37.28 sec by Max Park
  • 4x4x4: 18.42 sec by Max Park (starting to see a pattern here…)
  • 2x2x2 (average solve): 1.51 Lucas Etter
  • 2x2x2 (single solve): .49 sec by Maciej Czapiewski

And, just to show off, Stanley Chapel holds the record for a blindfolded 4x4x4 solve: 1 minute, 29 seconds.

Of course, now that we’ve mentioned one weird way to solve a Cube, let’s explore a few others.

Feliks Zemdegs set another world record by solving a 3x3x3 one-handed in 6.88 seconds. On March 1, 2015, Bhargav Narasimhan solved five Rubik’s Cubes one-handed in a blistering 1 minute, 23.93 seconds.

Daniel Rose-Levine holds the record for solving a 3x3x3 with his feet: 16.96 seconds. Not to be outdone, Que Jianyu unscrambled a trio of Rubik’s Cubes with his hands and feet simultaneously in just 1 minute, 36.38 seconds, in Xiamen, Fujian Province, China. (For the record, he solved one in each hand and one with his feet).

He later hung from a pole to record the fastest time to solve a Rubik’s Cube upside-down: 15.84 seconds. (He also holds the record for solving three Cubes while juggling, doing so in 5 minutes, 2.43 seconds.)

Jack Cai solved one blindfolded in 16.22 seconds. On July 22, 2018, at the Delhi Monsoon Open in Ghaziabad, Uttar Pradesh, India, Shivam Bansal shattered the field with the most Rubik’s Cubes solved while blindfolded: 48 out of 48 in under 1 hour.

George Turner holds the record for solving on a pogo stick: 24.13 seconds.

Krishnam Raju Gadiraju solved 2 Cubes simultaneously — underwater! — in 53.86 seconds. Kevin Hays achieved a world record for solving eight 3x3x3 Cubes underwater on August 19, 2015. He held his breath for 2 minutes and 4 seconds.

[Here’s a YouTube video of a different, but still impressive, underwater solve.]

Now let’s get truly ridiculous.

Phillip Kwa’han Espinoza holds the world record for most 3x3x3 Cubes solved while running a marathon. On November 14, 2015, he solved 839 Cubes over the course of 4 hours, 56 minutes, and 1 second during the 26.2 mile run in the REVEL Canyon City Marathon in Azusa, California, shattering the previous record of 175 Cubes.

26.2 miles is pretty good. But what about 12,000 feet?

That’s how high up Dan Knights was in June of 2003 when he jumped from a plane and solved a Rubik’s Cube in freefall while skydiving. He solved it in 34 seconds… which is good, because he only had 40 seconds before he’d have to deploy his parachute to safely execute a 12,000-foot fall.

To close things out today, let’s look at some Rubik’s records about quantity.

What about the most cubes solved:

  • one-handed while treading water in one hour? 137 by Shen Weifu
  • on a unicycle? 250 by Caleb McEvoy
  • on a bicycle? 1,010 by P K Arumugam

Finally, in January 27, 2018, the Kaligi Ranganathan Montford Group of Schools set a world record by bringing together the most people simultaneously solving Rubik’s Cubes — 3,997 — at Jawaharlal Nehru Stadium in Chennai, India. The average time to solve for the assembled students? A few minutes.

Imagine the records people will set in the 2020s.

The Human Limit of Speed-Puzzling?

stopwatch

When you think about achieving the impossible, what comes to mind? For runners, there’s beating the 4-minute mile. For the 100-meter sprint, it’s topping 10 seconds.

What do you suppose the puzzle equivalent would be? Solving puzzle #1 at the American Crossword Puzzle Tournament in under 2 minutes? We’ve seen Dan Feyer do that, and it was seriously impressive.

For Rubik’s Cube enthusiasts — especially the competitors known as speed-solvers or speed-cubers — that benchmark is a sub-3 second solve.

The current verified world record for speed-solving a Rubik’s Cube stands at 3.4 seconds, which shattered the previous record by almost a second.

(That record is for a single solve. Many Rubik’s Cube competitions involve an average time across five solved cubes, and the speed record for that hovers somewhere around 5 seconds.)

A lot goes into achieving a 3.4 second solve. There are specially designed cubes that allow for easier, quicker, smoother twisting and turning, so you can solve faster. I’m sure anyone who has solved a classic Rubik’s Cube found it at least a little bit clunky.

There’s also technique. Top solvers not only memorize solving patterns known as algorithms, but they have preferred combinations of moves.

It has been mathematically proven that no matter how complicated a scramble gets, you’re never more than 20 moves away from the solve. Now, of course a computer can analyze a cube and figure out those 20 moves. The human mind doesn’t work that way, so even top speed-solvers would require many more moves to solve the cube, even if they’re still lightning fast.

Which brings us to the next aspect of speed-solving: efficiency. Sometimes the fewest number of moves isn’t the fastest solve. For instance, if you have to rotate the cube in order to execute a turn, you’re wasting time you could otherwise spend twisting and turning toward the solution. So some solvers will avoid a slower rotational move by doing two turns instead, which ends up being faster overall. The trade-off of speed vs. efficiency is another way speed-solvers are whittling down time and approaching that 3-second threshold.

Top solvers can execute ten turns or moves per second. Based on the idea that no Rubik’s Cube is more than 20 moves away from being solved, that mathematically implies that a 2-second solve should be possible, if not probable.

In fairness, we’ve seen a solve take less than a second, but that involved a computer program and a robot solver.

So where do we currently stand? Well, there’s the 3.4 second official record, but former champion Feliks Zemdegs claims that, in training, he has achieved a 3.01 second solve.

Another speed-solver, Patrick Ponce, claims that he has solved a 3×3 cube in 2.99 seconds, but again, this is an unofficial time.

That being said, it certainly seems like the 3-second threshold, like the 4-minute mile before it, will eventually fall.

How fast is the human limit? Only time will tell.
