A crossword like you’ve never seen before

When someone sends me a link, claiming they’ve uncovered the most difficult crossword they’ve ever seen, I’m usually skeptical.

I mean, I’ve seen some diabolical crosswords in my day. From puzzle 5 at the American Crossword Puzzle Tournament and the meta-puzzles lurking in Matt Gaffney‘s Weekly Crossword Contests to the Diagramless and Double Trouble crosswords offered by our friends at Penny Dell Puzzles, it’s hardly tough to find challenging crosswords these days.

But this puzzle, originally created for the 2013 MIT Mystery Puzzle Hunt and made solvable (and rotatable!) online by Greg Grothaus, might just take the cake:

As you can see, there are clues across three sides of the hexagonal grid: the across clues, the down-to-the-left clues, and the up-to-the-left clues.

But these clues are unlike anything I’ve seen before.

It turns out that these are regexps, or regular expressions, sequences of characters and symbols that represent search commands in computer science.

Now, anyone who has used graphing features in Excel or crossword-solving aids on websites like XWordInfo, Crossword Tracker, or OneLook is probably familiar with simple versions of regexp. For instance, if you search C?S?B?, you’ll probably end up with CASABA as the likely top answer.

Of course, the ones in this puzzle are far more complicated, but the overlapping clues in three directions make this something of a logic puzzle as well, since you’ll be able to disregard certain answers because they won’t fit the other clues (as you do in crosswords with the across and down crossings in the grid).

But if, like me, you don’t know much about reading regexp, well then, you’ve got yourself a grid full of Naticks.

If anyone out there is savvy with regexp, let me know how taxing this puzzle is. Because, for me right now, it’s like doing a crossword in a foreign language.

But I’m not the only one who feels this way. When I first checked out the post on Gizmodo, they titled it “Can You Solve This Beautifully Nerdy Crossword Puzzle?” and I laughed out loud when the very first comment simply read “Nope.”

Glad to see I’m not alone here.

A New Year’s Eve Countdown!

It’s New Year’s Eve, and we are literally counting down the hours until 2016, so why not celebrate the end of 2015 with a little countdown of our own?

Here are my 10 favorite blog posts from 2015!


#10 Rubik ‘Round the World

One of the most amazing things about the world today is how interconnected we all are. The Internet has made it easily to not only keep in touch with far-flung friends, but to forge new, meaningful friendships and connections with staggering ease.

And I confess, I am a total sucker for those heartwarming clickbait videos that spread the message that we are all the same. (The one of that guy doing the same dance in countries across the world comes to mind.) So seeing people from all over the world solve a Rubik’s Cube one move at a time…what can I say? It got me.

#9 Holiday Puzzly Gift Guide

Every year, one of my favorite activities is putting together our Holiday Puzzly Gift Guide. I get to include the best products sent to me for review by top puzzle and game companies, mix in some of my own favorites, and draw attention to terrific constructors, game designers, and friends of the blog, all in the hopes of introducing solvers (and families of solvers) to quality puzzles and games.

#8 Music and Puzzles

Talking about how puzzles are relevant to daily life is one of my favorite subjects for blog posts. Brain health, stress relief, the long-term benefits of puzzle solving…we’ve discussed all these topics and more during my time as lead blogger.

This year I continued that tradition with this post about how listening to music can make you a more effective solver. It’s always interesting for me to do some research and really delve into a topic — especially scientific ones because they’re often so drastically misreported or misinterpreted by mainstream outlets — and give the PuzzleNation audience the straight story.

#7 The Dress

One of the most bizarre moments of 2015 was when someone shoved their iPhone in my face and asked me what color a dress was. It wasn’t until a few moments later that I found out this was a big thing on the Internet that people were vociferously debating.

The chance to explain exactly what was going on in the photo through one of my favorite puzzly mediums — the optical illusion — was too much fun to resist, and it resulted in one of the year’s most popular, most shared blog posts.

#6 The American Crossword Puzzle Tournament

Although it’s a highlight of the puzzly calendar every year, this year’s ACPT was extra special for me because it was the first I attended in person.

Not only did I get to meet a lot of top names in crosswords — in many cases, finally getting a chance to put names to faces after many emails and tweets exchanged — but I got to enjoy the Big Fight feel of seeing so many friends and puzzlers test their mettle against some great puzzles.

#5 A Puzzly Wedding Proposal

Our friends at Penny Dell Puzzles pulled off one heck of a puzzly coup when an intrepid fellow puzzler asked them for help proposing to his girlfriend with a special Escalators puzzle.

I reached out to the lucky fiancé and got his permission to share the story with the PuzzleNation readership, and as I learned more about who was involved and how they’d managed to make it happen, I just became more and more enamored with the story. I have no doubt that years from now, this will still be one of my favorite blog posts.

#4 Max Reviews the Boston Festival of Indie Games

Guest bloggers are nothing new to PuzzleNation Blog, as Sherri regularly pops in with her app reviews, but Max Galpern pushed things to another level with his appearances throughout the year. Not only did he pioneer our first video review (with assistance from Fred), but he took over the blog for an entire day with his review of the Boston Festival of Indie Games.

Here’s hoping we can get Max back for 2016 a few times, though I suspect he’ll be in high demand.

#3 Will Sudoku

We do a lot of reviews (board game and card game reviews, puzzle reviews, tournament reviews, app reviews, etc.) and I thoroughly enjoy introducing new puzzly products and events to my fellow PuzzleNationers and sharing my thoughts on them.

But it’s rare that we get the first shot at introducing a brand-new never-before-seen puzzle or product, and that’s what separates the Will Sudoku post from many others. Serving as the debut outlet for a new puzzle was great fun and very exciting, one of those rarities that made 2015 such a terrific year.

#2 Brooklyn Nine-Nine and Island Seesaws

Brain teasers were a big part of 2015 for the blog, since several challenging ones went viral this year. But I don’t think any of them taxed my brain — both to solve AND to explain how to solve — like the island seesaw brain teaser from an episode of Fox’s sitcom Brooklyn Nine-Nine did.

It is an epic-length blog post — one I needed a mathematician friend of mine to help me write — but it broke down a tough puzzle bit-by-bit and explained every step. In a year of brain-melting puzzle posts, it still stands out.

#1 Announcing Free Daily Puzzles for the Penny Dell Crosswords App

I almost put announcing the Android release for the App here instead — because so many people had been asking about it for so long — but in the end, the free daily puzzle announcement won out, and not simply because it was a terrific new feature for the App, one that I feel would draw a lot of new eyes to the product.

Getting to interview Fred and talk about not just what we’ve been working on for years, but where we were headed in the future, made it feel like a special event for the PuzzleNation Team as a whole. Plus it was a chance to introduce all of you to another member of the team, something I hope to do more of in 2016.

It may sound self-serving or schlocky to talk about our flagship product as #1 in the countdown, but it’s something that we’re all extremely proud of, something that we’re constantly working to improve, because we want to make it the absolute best it can be for the PuzzleNation audience. That’s what you deserve.

Thanks for spending 2015 with us, through logic problems and love stories, through dresses and debuts, through Rubik’s Cubes and revelations. We’ll see you in 2016.

It’s Follow-Up Friday: Thanksgiving Answers edition!

Welcome to Follow-Up Friday!

By this time, you know the drill. Follow-Up Friday is a chance for us to revisit the subjects of previous posts and bring the PuzzleNation audience up to speed on all things puzzly.

And today, I’m posting the answers to last week’s Thanksgiving Slide-O-Gram puzzle!


Here’s the grid and puzzle to jog your memory:

Using the given letters, place the eleven Thanksgiving words and phrases below into the diagram above, one per row. When all the words and phrases are entered properly, one of the columns reading down will spell out an 11-letter word that is related to Thanksgiving.

Casserole
Corn
Cornucopia
Cranberry sauce
Giblets
Pumpkin pie
Rolls
Stuffing
Sweet potato
Turkey
Turnip

So let’s take a look at the completed grid!

Our bonus answer tying the word list together was, appropriately enough, CENTERPIECE.

(If you had trouble with the puzzle, the anchor words that would’ve gotten you going were Corn, Cornucopia, Giblets, Pumpkin pie, and Cranberry sauce.)
