Tie Yourself in Knots With Rope Puzzles!

rope puzzle rings

What comes to mind when you think of a mechanical brain teaser? Do you think of a puzzle box or linked metal shapes? Do you think of wooden pieces that need to be fitted together to form a particular shape, or the twists and turns of a Rubik’s Cube or sword puzzle?

I would wager that rope isn’t the first puzzle piece that you think of. Which is surprising, because rope is part of plenty of different brain teasers. And they date back further than you’d think.

Check out this tricky tangled knot. This mix of rope and clay guarded the tomb of King Tut for centuries. Experts in rope and knot-tying have identified many of the knots involved, and claim that there’s no way to remove the rope and open the doors without breaking the clay seal depicting Anubis, the jackal-headed god entrusted with the protection of the dead.

Although it’s rare to find rope puzzles like this guarding tombs these days, they still guard other treasures. Like this wine bottle for instance.

This brain teaser serves as a fun (or annoying) way to add a little flavor to a traditional housewarming or holiday gift.

It’s just one example of a wide array of mechanical brain teasers known as disentanglement puzzles.

rope puzzles

These puzzles rely on careful manipulation to make seemingly impossible actions — like passing a rope with a wooden ball attached through a hole too small for the ball — quite simple with clever maneuvering.

And whereas other tangle puzzles that are all metal or all wood are great and offering different challenges, the addition of a rope or two can add a TON of variability and new options to a puzzle. Pieces slide along it, and the rope can be twisted, rolled, or threaded between pieces. This one element triples the possibilities.

As you might expect, rope puzzling has also made the leap to mobile apps.

Games like Tangle Master stick to the disentanglement theme, demanding you untie a number of ropes in a certain number of moves. Later complications include locked ropes you can’t move until other ropes are eliminated, and even bombs that countdown to force certain moves.

Cut the Rope offered a different challenge, requiring solvers to deliver a candy to the waiting mouth of a hungry pet by cutting the rope. Along the way, you’d try to collect stars. The game was a mix of strategy and timing, and I can remember more than a few friends obsessed with this app a long while back.

Where could rope puzzles go from here? Anywhere, really, as long as puzzly minds are out there to try out new ideas.

There are videos online of creative geocaches/letterboxes involving string or rope. I’ve seen them employed in escape room puzzles — once to decode a message, another time to trace a connect-the-dots pattern on a board of nails, and elsewhere to connect two distant objects and hold them in place — and I’m sure that’s not the last I’ve seen of ropes there.

Solution to the Smith-Jones-Robinson Problem!

[Image courtesy of SharpBrains.com.]

A week ago, we shared a brain teaser sent in by a PuzzleNationer named Brian, who challenged us to solve the following challenge.

Today, we’re going to share not only the solution, but how we got there! Please enjoy this brief solve and tutorial, inspired by one of your fellow PuzzleNationers!


The Smith-Jones-Robinson Problem

Every fact is important. The puzzle is as follows:

On a train, three men named Smith, Jones, and Robinson are the fireman, brakeman, and engineer, but not necessarily in that order. Also on the train are three businessmen who have the same names as the train crew. They will be referred to as Mr. Smith, Mr. Jones, and Mr. Robinson.

  • Mr. Robinson lives in Detroit.
  • The brakeman lives exactly halfway between Chicago and Detroit.
  • Mr. Jones earns exactly $20,000 per year, paid in thousand-dollar bills.
  • The brakeman’s nearest neighbor, one of the passengers, earns exactly three times as much as the brakeman, and is also paid in thousand-dollar bills.
  • Smith beats the fireman at billiards.
  • The passenger whose name is the same as the brakeman’s lives in Chicago.

From the information listed above, can you figure out the name of the engineer?

We’re given one exact number, so let’s start there.

The brakeman’s nearest neighbor, one of the passengers, earns exactly three times as much as the brakeman. Mr. Jones earns exactly $20,000 per year, which cannot be divided evenly by three (in thousand dollar bills), so Mr. Jones is NOT the brakeman’s nearest neighbor.

The brakeman lives exactly halfway between Chicago and Detroit, and Mr. Robinson lives in Detroit, so Mr. Robinson cannot be the passenger who lives nearest to the brakeman. And as we just determined, Mr. Jones is also not the brakeman’s nearest neighbor. That leaves Mr. Smith as the brakeman’s nearest neighbor.

This tells us about the passengers, but how does it help us with the train crew?

Well, the passenger whose name is the same as the brakeman’s lives in Chicago. And neither Mr. Robinson nor Mr. Smith (who is nearest to the brakeman) can live in Chicago. That tells us Mr. Jones lives in Chicago.

This means that the brakeman’s name is Jones.

We can finally turn our attention to the train crew now.

Now that we know the brakeman’s name is Jones, that leaves only Smith and Robinson as possibilities. And we know that Smith beats the fireman at billiards. Smith can’t be the fireman or the brakeman, so Smith must be the engineer.

Did you identify the engineer and outwit the Smith-Jones-Robinson Problem? Let us know in the comments section below. We’d love to hear from you!

What Is Good Trivia?

Trivia is an integral part of many forms of puzzling. Crosswords involve a fair amount of trivia, as do many clued puzzles. Themed puzzles — particularly those that don’t give you a word list — also require some solid trivia knowledge. Brain teasers, riddles, escape rooms… all can involve trivia on some level.

But what do we mean when we say trivia? As it turns out, not everyone agrees.

Merriam-Webster defines trivia as “unimportant matters, trivial facts or details,” then acknowledges the secondary meaning “a quizzing game involving obscure facts,” a definition which didn’t come around until the 1960s.

That first definition certainly fits the bill in many trivia books and games. They’ll claim any random fact as trivia, obscure or otherwise.

But I don’t think obscurity defines trivia. After all, plenty of great evenings of bar trivia don’t require obscure topics or the minutiae of various subjects; they simply require a wide swathe of general knowledge and a decent grasp of recent news and pop culture.

The first time I gave serious thought to the question “what is trivia?” occurred years ago when I started working on a movies and television-themed subscription crossword book for the folks at Penny Press. In addition to creating puzzles centered around a central theme for the issue — soap operas, Star Wars, animal movies, etc. — I also created lists of trivia questions to be included in the book.

I would compile a list of 25 or 30 trivia questions — brief enough to read along the bottom of the page, but hopefully interesting enough to be worth the solver’s attention — and sent them off for consideration.

That’s when Editorial Manager Warren Rivers introduced me to his definition of trivia:

What a lot of people call “trivia” strike me as things one should or could have learned in school. Those are things I don’t consider trivia. Trivia to me are the things that I wouldn’t expect a person to know, or better yet includes a “twist” or an element of surprise.

And I think that’s a key element in good trivia: that interesting twist or surprise. It’s not just informational recall. There’s something more there, whether it’s in the answer or the clever construction of the question.

But there are plenty of knowledgeable trivia enthusiasts out there, and I wanted their input as well.

One of the first people I asked was Stella Zawistowski, a crossword constructor, powerlifter, and trivia supplier for Geeks Who Drink, who clearly has one of the coolest resumes in the world.

I think what you are asking me is, “what is GOOD trivia”?

Good trivia accomplishes one of two things: teaches people something they don’t know and will find interesting, or nudges them to realize they know more than they think. This means that what constitutes good trivia is highly audience dependent. The astronomy question that is too easy to be interesting to a group of JPL employees could be fascinating to a general audience. Conversely, a general-audience question about Handel’s “Messiah” could be very boring to a group of classical music experts.

IMO one of the best trivia questions I’ve ever written is “The hand-cut and -sewn lace of this instantly famous wedding gown includes four types of plants: roses, shamrocks, daffodils, and what?”

The reason I think it’s good is that it fits into the “nudge people to realize they know more than they think” category. On its surface, this is a fashion question. How on earth is one supposed to know a detail as tiny as what flowers were embroidered on the lace of somebody’s wedding gown?

But if you think a little more carefully, you’ll see that the bride is marrying a British royal, and if you know that the three plants mentioned in the question — rose, shamrock, and daffodil — represent England, (Northern) Ireland, and Wales, respectively, you then realize: Oh, she’s representing the four UK countries, and the one that’s missing is Scotland. So the answer is the thistle, the national flower of Scotland.

I very carefully chose which one of those I left out, too! If you give shamrock, daffodil, and thistle, rose is incredibly easy, easier than I wanted the question to be. Take out shamrock, and I think it’s a bit harder to realize that the three remaining flowers are national symbols. Take out daffodil, and the solver unfairly has to choose between daffodil and leek, the latter of which is also a botanical national symbol of Wales. I don’t know that anybody ever wanted leeks on her wedding gown, but I didn’t want anyone to get the question wrong simply because they went with the wrong national symbol.

Stella gets into a very important aspect of quality trivia that you don’t immediately consider: the phrasing and construction of the question.

Sure, the answer is the payoff, but the question is how you get there. The question is often the source of the a-ha! moment we so desire.

According to the crew at Geeks Who Drink, “the usual job of the conscientious quiz-writer is to start with a kernel of something you don’t know, and stir in just the right mix of hints and parallels to lead you to the correct answer (yes, no matter what it feels like, we DO want you to get most of them right).”

And that can take time. Thorsten A. Integrity, commissioner of the invite-only Learned League trivia website, can spend up to 30 minutes on each of the six trivia questions featured in a given day of trivia during one of the four seasonal competitions.

He usually starts with an interesting tidbit from a reference book and builds the question out from there. He fact-checks everything and has his questions professionally copyedited.

That effort creates a conversation in the brain. You ask yourself about different aspects. You rule things out, as Stella shows in her example. A good trivia question gives you enough to get you started and JUST enough to eliminate some false paths. (Although there’s nothing wrong with a tricky trivia question that leads you down the incorrect path a little bit.)

On trivia nights, or in trivia games, that conversation can quickly become fun and engrossing. As Ken Jennings once said of trivia, “It can lubricate social interaction. I like to see it as a way to build bridges.”

Are you a trivia fan, fellow puzzlers? Let us know your favorite trivia questions and bits of trivia below. We’d love to hear from you! (We could even compile them into a future blog post!)

Go For a Nice Relaxing Puzzle Hunt with Letterboxing!

Who can resist a treasure hunt? Who doesn’t want to play the role of the clever intrepid adventurer who reads maps, deciphers clues, solves riddles, and finds a hidden cache that eluded so many others?

We’ve discussed them in the past, covering famous ones like Forrest Fenn’s poem or the visual treasure hunt clues of The Secret, as well as tips for creating one of your own.

But did you know there’s another sort of treasure hunting out there that requires nothing more than your wits, your patience, and your willingness to exercise and explore?

[Image courtesy of Underhobby.]

It’s called letterboxing.

Essentially, you’re hunting for small, weatherproof boxes in publicly accessible areas — parks, for instance — with the goal of celebrating your success locating the well-concealed box. From a given starting point — a letterboxing catalog, or a website, or one given to you by the letterbox designer themselves — you must hunt down the box. (Your state might even maintain an archive of available letterboxing spots. Mine certainly does!)

Sometimes there are clues, or puzzles to be solved, or it’s simply meant to be found by determined, keen-eyed hunters.

Inside, you’ll find a logbook awaiting your personal stamp (to mark that you found it) as well as a stamp unique to that letterbox for you to use in your own record book to record your success in locating the box.

Devoted letterboxers often keep careful records of how many letterboxes they’ve planted, how many they’ve found, which letterboxing events they’ve attended, and more.

And it’s a hobby that dates back more than 150 years!

Now, if this sounds familiar, there’s good reason for that. Over the last fifteen years, an updated version of letterboxing has emerged: geocaching.

Geocaching functions mostly along the same lines, but with one crucial difference.

Geocaching is all about finding exact GPS coordinates.

But it can also involve the same exploration, puzzling, and problem-solving as letterboxing. I’ve seen some that contain puzzles that reveal coordinates to other geocaches, like popsicle sticks that have to be sorted to reveal the necessary numbers. There are even some that require you to solve a puzzle to open the letterbox itself.

Some people are very clever indeed, and they’re waiting for you to accept the challenge.

Have you ever been letterboxing or geocaching, fellow puzzlers and PuzzleNationers? Are you planning to try it out in the future? Let us know in the comments section below. We’d love to hear from you!

You may be familiar with the board game Schmovie or hashtag games on Twitter.

For years now, we’ve been collaborating on puzzle-themed hashtag games with our pals at Penny Dell Puzzles, and this month’s hook was #PennyDellPuzzleQuote. Today’s entries all mash up Penny Dell puzzles with famous quotations!

Examples include: “Be the Changaword you wish to see in the world,” “Loose Blips sink ships,” or “Cogito, ergo Sum Triangles.”

So, without further ado, check out what the puzzlers at PuzzleNation and Penny Dell Puzzles came up with!


One cannot Step by Step in the same river twice.

We’ll Anacross that bridge when we get to it.

One and Only if by land, Two at a Time if by sea.

You miss 100% of the shots you don’t Give and Take.

Piece by piece comes from within. Do not Word Seek it without.

It ain’t over ’til it’s Overlaps.

A Penny Press saved is a Penny Press earned.

It takes two to Tanglewords.

The buck Stoplines here.

It’s all right there in Block and White.

Leave no Stepping Stones unturned.

Don’t judge a Bookworm by its cover.

Chain Words are only as strong as their weakest Linkwords.

Picture This…worth a thousand Word Seeks.

A stitch in time saves Three from Nine.

When the going gets Mind Boggler, the Mind Boggler gets going.

When life gives you Share-A-Letter, make Alphabet Soup.

All Four One and one Four-Most.

That’s one small Stepping Stones for man…

You are the Masterwords of your unspoken Word Seeks, but a slave to the Wordfinders you have spoken.

PN Product Review: Godzilla: Tokyo Clash

Today’s board game review was selected by the PuzzleNation readership through polls on social media!

Would you like more polls to determine reviews, pop culture recaps, and other blog content? Let us know in the comments section below. We’d love to hear from you!


The-original-Godzilla-rel-001

Godzilla returned to theaters this year for the umpteenth time with Godzilla vs. Kong, and after 67 years of cinematic dominance, the King of the Monsters is still an incredibly popular figure in pop culture.

That being said, Godzilla’s board game resume isn’t nearly as impressive. In fact, it’s mostly the pits. Surprisingly, making a good board game about monsters fighting each other is harder than you’d think. (Only two come to mind — King of Tokyo and Smash City — and sadly, neither features cinema’s most iconic city-smashing monster.)

Perhaps even more surprising is the fact that this dilemma might’ve just been solved by a very unlikely source, a company more famous for their collectible figurines than their games: Funko.

In today’s blog post, we’re reviewing a Godzilla game that finally got it right, as we explore Godzilla: Tokyo Clash.

714M7tnjGTL._AC_SL1300_

Not only do you have four famous film kaiju (aka monsters) to choose from — Godzilla, Mothra, King Ghidorah, and Megalon — but the game board is different every time you play, thanks to the tile design that allows for numerous different arrangements.

Each of the monsters has a special ability unique to that monster, as well as a deck of action cards that are specifically designed for your monster. Whoever is playing as Godzilla will have different moves, tactics, and attacks than the person playing as Mothra, King Ghidorah, or Megalon, and this adds further replay value to the game.

Plus you randomly choose two ways that the city tries to fight back against the monsters, adding further variety to the wrinkles that color the game play on multiple playthroughs.

You have an energy bar, which is used to control how much you attack the vehicles, buildings, and other kaiju around you. So, in addition to planning for the moves other players make — as well as the moving vehicles on the game board — you also have to manage your attacks based on your available energy.

Smashing buildings and vehicles gives you energy, which you can use to attack the other monsters on the board. Successful attacks give you trophies, which count toward your overall Dominance point total. Whoever has the most points at the end of the game wins.

That’s right! Every player stays active for the whole game — unlike many other monster-fighting games, where players can be eliminated and then you just sit around and watch the rest of the game.

The art is gorgeous, evoking a vibrant style inspired by classic Godzilla movie posters (and don’t worry, the instructions are in English). The miniatures are marvelously detailed, and the game is loaded in references to the films. You don’t have to know them to play the game, but for diehard Godzilla fans like myself, it’s vindication after years of mediocre kaiju-themed games.

And the game is very reasonably priced, considering the quality of the miniatures, the game board tiles, and the overall art. This ticks a lot of boxes for both board game fans and Godzilla enthusiasts.

That being said, the game does have some downsides. The two-player version is far less engaging than the three- or four-player versions, because your tactics are so limited by just throwing vehicles back and forth at each other and smashing buildings. The strategic moves and planning are deeper and far more enjoyable with more targets, threats, and things to consider.

81vjLbMWEwL._AC_SL1500_

It might sound silly, but in this game about monsters smashing things, it’s simply more fun when there are other people smashing stuff too.

Also, I’m not a huge fan of the Dominance system, since it’s a little distracting  to have two sets of numbers to keep track of — the energy and the victory points — but I confess I can’t think of another mechanic that would still allow all of the players to keep playing.

All in all, I was very impressed by this game. It’s easy to pick up, fun to master, and offers a ton of variety for new and experienced players. Plus there’s a surprising amount of tactical puzzling involved, which elevates the game beyond a simple you-go-then-I-go mentality.

This game is a win.
