2017 KenKen International Championship

If you like puzzles and ping pong, then Pleasantville, NY, was the place to be on December 17.

More than 200 Kenthusiasts — people who love KenKen puzzles — descended on Will Shortz’s Westchester Table Tennis Center for the 2017 KenKen International Championship (or the KKIC, for short). Participants followed 1.5 hours of solving KenKen puzzles with a pizza party and several hours of table tennis.

The competition consisted of three rounds, with the three puzzles in each round slightly larger and more difficult than those from the previous round. Consequently, competitors were given 15, 18, and 20 minutes to complete the puzzles in the first, second, and third rounds, respectively.

Competitors earned 1,000 points for each completely correct puzzle, and 0 points for an incomplete or incorrect puzzle. In addition, a bonus of 5 points was earned for every 10 seconds in which a puzzle was turned in before time was called. So, let’s say you got two of the three puzzles correct and handed in your answers with 30 seconds remaining in the round; then, your score for that round would be

2 \times 1000 + \frac{30}{10} \times 5 = \bf{2{,}015}

The leader after the written portion was John Gilling, a data scientist from Brooklyn, whose total score was 10,195. And if you’ve been paying attention, then you know what that means — Gilling earned 9,000 points for completing all of the puzzles correctly, so his time bonus was 1,195 points… which is the amount you’d earn for turning in the puzzles 2,390 seconds (combined) before time was called. The implication? Gilling solved all 9 puzzles from the written rounds — which contained a mix of puzzles from size 5 × 5 to 8 × 8 — in just over 13 minutes.

Wow.

As a result, Gilling, the defending champion, earned a spot in the Championship Round against Tess Mandell, a math teacher from Boston; Ellie Grueskin, a high school senior at The Hackley School; and Michael Holman, a technology consultant. In the final round, each of them attempted a challenging 9 × 9 puzzle, which was displayed on an easel for the crowd to see. Solving a challenging 9 × 9 is tough enough; having to do it as 200 kenthusiasts follow your every move is even tougher.

So, how’d they do? See for yourself…

When the dust settled, Gilling had successfully defended his title. For his efforts, he received a check for $500. But more importantly, he retained bragging rights for one more year.

If you think you’ve got what it takes to compete with the best KenKen solvers, try your hand at the 9 × 9 puzzle that was used in the final round. In the video above, you saw how fast Gilling solved it to win the gold. But even the slowest of the four final-round participants finished in under 15 minutes.

Again, wow.

Finally, I’d be failing as a father if I didn’t mention that my sons Alex and Eli competed in the Delta (age 10 and under) division. Though bested by Aritro Chatterjee, a brilliant young man who earned a trip to the 2017 KKIC by winning the UAE KenKen Championship, Eli took the silver, and Alex brought home the bronze. They’re shown in the photos below with Bob Fuhrer, the president of Nextoy, LLC, the KenKen company and host of the KKIC.

AWOKK, Day 6: KenKen Glossary

KENgratulations! You’ve made it to Day 6 of MJ4MF’s A Week of KenKen series. If you happened to miss any of the fun we’ve had previously…

Robert F. Fuhrer is a toy inventor with a knack for coming up with creative names, including Crocodile Dentist, Gator Golf, T.H.I.N.G.S. (Totally Hilarious, Incredibly Neat Games of Skill), Rumble Bugs, Missile Toe (literally, a rocket in the shape of a toe), and many others. As the president of Nextoy, LLC, which holds the registered trademark for KenKen®, Bob now uses his creative naming abilities for the appellations of KenKen-related products.

The word that started this post, KENgratulations, is just one of his many linguistic creations. I rather like the term he coined to describe the computer application that randomly generates KenKen puzzles.

KEN·er·tor n. the “machine” (computer application) used to automatically generate KenKen puzzles

Quick! We need more 6 × 6 puzzles. Crank up the Kenerator!

The name conjures images of a machine from Willy Wonka.

Oompa, loompa, doom-pa-dee-do,
I’ve got a perfect puzzle for you…

Numbers and operations go in, puzzles come out.

The Kenerator

Bob can also take credit for the following:

KEN·cil n. a pencil used to solve KenKen puzzles

I prefer kencils rather than pens when solving KenKen puzzles.

KEN·grat·la·tions n. an expression of praise for solving a KenKen puzzle

Kengratulations for solving that puzzle in less than 7 years!

KEN·thu·si·ast n. someone who likes to solve KenKen puzzles

Most Kenthusiasts solve more than one KenKen puzzle a day.

There’s no doubt, Bob is good. But as you saw in a previous post, I’ve got a knack for coining terms, too…

KEN·tath·lon n. competition involving multiple KenKen events

I complete a Kentathlon consisting of a 4 × 4, 5 × 5, and 6 × 6 puzzle every morning.

e·go·KEN·tric adj. a person who thinks that they are better than others at solving KenKen puzzles

He’s completely egokentric, even though he’s never won a KenKen tournament.

KEN·tral of·fice n. where KenKen puzzles are made

The Kenerator resides in the kentral office.

KEN·te·nar·i·an n. person who has solved 100+ KenKen puzzles

He became instantly addicted to KenKen puzzles; he became a kentenarian in less than 3 weeks.

su·per·KEN·te·nar·i·an n. person who has solved 100+ KenKen puzzles in one day

She became a superkentenarian by completing all the puzzles in Ferocious KenKen on Saturday.

KEN·ta·gon n. the arena in which KenKen tournaments take place (analogous to the Octagon, the eight-sided chain-link enclosure used for Ultimate Fighting Championship matches, though usually less violent)

Enter the kentagon, prepare to solve!

KEN·o·pause n. the period in a puzzle solver’s life when KenKen ceases to be fun

Kenthusiasts who have entered kenopause usually solve fewer than one puzzle a day, on average.

KEN·i·ten·tia·ry n. where KenKen solvers are locked up if they’re caught cheating (syn prism)

If you copy off your neighbor at a KenKen tournament, you’ll be sent to the kenitentiary.

KEN·al·ty n. a disadvantage imposed on a puzzle solver at a tournament for an infringement of the rules

He was given a 15-second kenalty for “using a kencil in an unsafe manner.”

KEN·ais·sance n. the period from roughly 2008 to 2010 when KenKen puzzles experienced tremendous growth in popularity, likely the result of publication in The Times (London), the NY Times, and other newspapers

Harold Reiter’s interest in KenKen started long before the Kenaissance.

KEN·der·foot, n. an amateur; someone who has solved only a few KenKen puzzles

He’s such a kenderfoot; he doesn’t even know the X-wing strategy!

KEN·den·cies n. the habits of a KenKen solver; analogous to a “tell” in poker

He has a kendency to complete all of the addition cages before attempting any subtraction cage.

hy·per·KEN·ti·late n. to breathe heavily while solving a puzzle (usu., a result of having difficulty)

At the 2013 KenKen International Championship, she started to hyperkentilate when she had trouble with a difficult 6 × 6 puzzle.
