Krish Crushes Cubes

If you’re like me, you can solve a Rubik’s cube in about the time it takes a spaceship to reach the Andromeda galaxy.

And return.

If you’re like Krish Shah-Nathwani though, you can do it in 1 minute, 41 seconds.


He’s been cubing since 2014. He was a Bedford Middle School student, and spent days teaching himself with an online tutorial. Very quickly, Krish got hooked.


His first competition came a few months later, at Yale. His time of 17.89 seconds — yes, you read that right — was not good enough to earn honors (you read that right too). But Krish had fun, made friends, and loved the cubing community.

He began specializing in pyraminx (a tetrahedron puzzle with nearly a million different positions). Before year’s end, he placed 2nd at an MIT event.

2015 brought Krish’s 1st sub-10 second solve; his 1st win, and a trip to the nationals in Portland, Oregon.

He loved competitions. “They’re a great social gathering with like-minded people,” Krish — now a Staples High School sophomore — says. “I’ve made friends all across the country.”

Last year, he entered 13 competitions. Computers generate “scrambles.” Each cuber gets 5 different “solves.” The best and worst scores are discarded, because a lucky scramble can allow a contestant to skip a few steps. Scores are based on the average time of the middle 3 solves.

Krish got his first sub-10 second average. That was a “huge milestone.”

Kirsh Shah-Nathwani intently works a cube.

He also had his first blindfolded success. When the timer starts, cubers memorize what they see. He imagines a sequence of letters, then solves the cube using a mnemonic.

So that 1:41 time? It includes the seconds he spent memorizing the cube.

Last year, at nationals in Fort Wayne, Indiana, Krish reached 2 semifinals and 1 finals.

At Penn, he finished second in the “normal” category (a regular Rubik’s cube solve). The winner was the North American record holder for fastest solve. “He’s one of my idols,” Krish says. “So I didn’t feel that bad.”

6×6 Rubik’s cube

Competitions involve many different categories. Krish can do 2×2, 3×3, 4×4, 5×5 and 6×6. He’ll do 7×7 this June. (It’s worth noting — though Krish says it very casually — that he does 3×3 with only one hand — and blindfolded.)

He also does square 1 (shape-shifting) and megaminx (a dodecahedron).

Is there anything Krish can’t do?

“I can’t solve with my feet,” he admits. “It takes me like 10 minutes. I have a friend who did it in 16.9 seconds.”

A key characteristic of a good cuber is resilience, Krish says. You do not need “genius IQ,” or a mathematical mind. “Once you understand how a cube works, it’s simple,” he claims.

As you may have figured, Krish is the real deal. He’s sponsored by Speed Cube Shop, an online seller of cubes, timers, lubricants, carrying bags, and anything else a competitive cuber could want.

Krish gets his cubes for free (and displays their logo prominently).

That’s a big help. Each cube turns differently, he explains. And each cuber has his particular style. A serious cuber needs lots of cubes.

Krish puts them to good use. You can see them on his YouTube channel. He has over 1,500 subscribers. He’s so well known, in fact, that at competitions he gets asked for autographs and selfies.

In March, Krish won his first competition, in Poughkeepsie, New York, with an average time of 8.36 seconds. He set a personal best time there too: 6.73 seconds. That got his name on the World Cube Association home page.

This summer, Krish heads to Nationals in Salt Lake City, to compete against some of the best in the world.

But, Krish insists, all this competition is not about beating others.

“It’s cool to get accolades. But it’s more about competing against yourself. I’m ecstatic when I better myself.

“And we’re all supportive of each other. When Daniel Gutierrez beat my state record, I was so happy. He practiced so long, and worked so hard.”

Speaking of practice: Krish spends 2 to 3 hours a day on his cubes.

“It’s not an obligation. I enjoy it,” he says. “I do it while I’m on video calls with friends in other states. We talk with each other about everything. And we race too.”

Every month or so, he sees those cubing friends in real life, at competitions.

His other friends — those at Staples — think his cubing is cool. Teachers are impressed too.

The entire school saw see Krish in action recently, at the talent show. He was just as entertaining as the singers and dancers.

Which leads to this important detail about Krish Shah-Nathwani: He has a life beyond cubing.

A member of Staples Players, he has performed onstage in “Music Man,” “Newsies,” and the One-Act Play Festival.

“It rounds me out as a person,” he says. “Cubing brings out my analytical side. Players brings out my artistic side.”

But he can’t resist one final plug for his greatest passion.

“Give it a try!” he urges. “We need more Connecticut cubers.”

More Challenging Than A Blind Rubik’s Cube

Noah Arthurs has set a US record for blind-folded Rubik’s cube solving:

The Westport connection: Noah’s father, Lee, is a Westporter (and District 8 RTM representative).

Congrats, Noah. But why not help your dad solve other problems — like what to do about Westport’s pension obligations, Baron’s South, and downtown parking.

They’re a lot tougher to figure out than even an unseen Rubik’s cube.

Do that, and I’ll really be impressed.
