I’m gonna need a stepladder.

Plenty of places claim they offer large crosswords for the truly devoted solver, but nobody holds a candle to the Ukraine, whose citizens crafted this 100-foot-tall monument to puzzling.

Located in the city of Lviv (Lvov, to Russian speakers), the puzzle is an art installation perfectly designed to keep visitors thoroughly challenged. The clues are scattered on landmarks throughout the city, further encouraging both tourism and brain-boosting.

The puzzle appears incomplete during the day, but at night, special lighting reveals the answers in fluorescent paint.

I can only hope this will inspire other communities to raise the stakes even higher. Crop crosswords that can only be solved with Google Maps! Landscaping sudoku hedges complete with topiary set numbers! Cowboy-style word searches where you actually lasso words on cattle!

Okay, maybe not that last one. But hey! At least I’m trying! The artists of Lviv have set the bar — not to mention the grid — pretty darn high.

Puzzles in Pop Culture: MacGyver

From Stanley’s love of crosswords on The Office to the clever conundrums constantly conjured by the Riddler in various iterations of Batman, puzzles have played roles both big and small in numerous TV shows and films.

In previous editions of Puzzles in Pop Culture, I’ve recapped a classic episode of M*A*S*H and discussed the numerous puzzle-centric episodes of The Simpsons.

This time around, we’re delving into the rich history of another famous TV puzzler, tinkerer, and all-around problem solver, Angus MacGyver.

Oh yes, make no mistake; while plenty of bullets were flying and criminal enterprises unraveling over the course of the show, MacGyver remained a puzzle solver through and through, displaying at least once an episode an almost-magical ability to solve brain teasers, mechanical puzzles, and other challenges.

True, the average puzzle-solving experience doesn’t usually include building an airplane out of bamboo or making a cannon from a garbage can and discarded cleansers, but a lot of the same skills apply, like abstract thinking and an affinity for combining contextual clues with a storehouse of personal knowledge and trivia.

At heart, I think we can all agree that when he wasn’t globetrotting, battling shadowy conspiracies, debunking UFOs, or encountering yet another ex-girlfriend in peril, MacGyver was probably doing the Sunday New York Times Crossword and solving Rubik’s Cubes with his feet.

And so, with that in mind, let’s take a look at a season-six episode of MacGyver titled “Eye of Osiris.”

In this Raiders of the Lost Ark homage/ripoff, MacGyver is recruited to help out at an archaeological dig seeking evidence of Alexander the Great’s tomb. (MacGyver has one third of a medallion that will supposedly lead to the tomb; the researchers have the other two pieces.)

As expected, there are criminal forces at work, and two (count them!) former foes of MacGyver’s are lurking in the shadows. The puzzling — well, poetry-decoding / riddle-solving, really — begins when MacGyver deduces the location of the tomb after the crooks steal the medallion.

(MacGyver, naturally, manages to reproduce the medallion from an imprint of the original in a box of sand.)

He and the scientists head for the tomb, only to be sealed inside with the criminals by an ancient booby trap. (Ain’t that always the way?)

Here, MacGyver confronts the first of the puzzles awaiting him inside the tomb, as the episode basically becomes a monsterless Dungeons & Dragons-style dungeon romp.

A statue of Anubis is in the room, along with a few dozen urns of different shapes and sizes. Naturally, Mac realizes they have to find the right urn, and it becomes a classic mechanical balance-the-weight puzzle.

When they do so correctly, a door opens, and they head into a grand crypt for Alexander the Great, with another elaborate mechanical puzzle (based on the Tree of Life, and requiring fire, water, and all kinds of elemental shenaniganry).

Any viewer who has been paying even the slightest attention can solve the puzzles faster than the heroes or villains, and soon enough, we earn our reward:

Yup, a sapphire the size of a small watermelon or a fat house cat, supposedly created when a meteorite crashed to Earth nearby.

Naturally, disturbing the sapphire activates another trap — closing walls this time — and more riddle-solving allows MacGyver and the scientists to escape the room before a giant stone smashes through the wall and chases them down a corridor. (Sound familiar?)

One last puzzle awaits our heroes before they escape, sapphireless but alive. (The various traps managed to thwart the villains for the heroes, as you’d expect.)

Once again, a solid knowledge of trivia and puzzling has saved the day!

Hope you enjoyed this little trip down memory lane. Until next time, keep calm, puzzle on, and I’ll catch you again soon.

P.S. It’s worth noting that I first saw this episode years and years ago while home sick from school. In the years before the Internet became the storehouse of all information, trivial and otherwise, I could find little to no proof that this episode existed as I remembered it.

Until a few years ago when I tracked the episode down on Netflix, I was half-convinced I’d conjured it in some sort of fever dream. *laughs*

You betcha!

A few months ago, I posted a video of various bar bets that are perfect for the puzzle-minded prankster looking to earn a buck or two from an unsuspecting friend.

The same people behind that video have produced another, featuring 10 tricks and brain-teasers with which to baffle and challenge your friends. (Of course, if you keep bamboozling them out of money, they probably won’t want to hang out with you anymore, so use these tricks sparingly.)

Enjoy the following ode to visual trickery!

Why do so many puzzles involve crossing rivers?

Seriously, there’s the one with the cabbage, goat and wolf (and variations thereof), there’s the Bridges of Konigsberg, and this one. When it comes to weirdly common puzzle scenarios, it’s right up there with drawing paired socks at random and turning two triangles into four. Puzzlers might have too much free time on their hands. *laughs*

ANYWAY. I digress.

A buddy of mine sent me a brain teaser the other day, and it seemed like the perfect challenge for my fellow puzzle fans. Although it tends a bit more toward the mathematical-word-problem side than a straight brain teaser, I think it will get your deductive juices flowing!

Bridge and Torch

Four people come to a narrow bridge at night. Among them, they have one torch, which has to be carried in order for anyone to cross.

Only two people can cross the bridge at a time. Person A can cross the bridge in 1 minute, B in 2 minutes, C in 5 minutes, and D in 8 minutes. When two people cross the bridge together, they go at the slower person’s pace.

How can they all cross the bridge in 15 minutes or less?

(Oh, before I go… a quick bit of internet sleuthing reveals that this puzzle originated in Garth Sundem’s Brain Candy: Science, Paradoxes, Puzzles, Logic, and Illogic to Nourish Your Neurons. Credit where credit is due, always. Enjoy!)

Mindbending illusions!

There are puzzles to solve and mysteries to unravel… and then there are the mindboggling optical illusions that play with your perception.

Stationary things move, items big and small end up being the same size… it’s simultaneously fascinating and a little unnerving.

The folks as Gizmodo assembled a gallery of twenty optical illusions of all sorts, including several favorites of mine like the Fraser Spiral and a neat variation on the Necker Cube, and you should definitely check it out, if only to challenge your eyes and your brain in a different way today.

When pigs fly? You’ve got yourself a deal!

I’m a sucker for a good mechanical puzzle. Figuring out which piece goes where to complete a given item or accomplish a certain task is a staple of many roleplaying games and video games, and coincidentally, that’s one of my favorite aspects of each.

Rube Goldberg machines, perhaps the pinnacle of mechanical puzzle tinkering, never cease to entertain or amaze me, as you can tell by some of the videos Eric and I have posted in this blog over the last few months.

(They also make for excellent set pieces in movies, The Goonies and National Treasure providing two entertaining examples.)

Like many of those who enjoy mechanical puzzles, I can trace my interest back to the board game Mouse Trap, which featured an elaborate multi-stage trap to snare your fellow mice. I don’t recall ever actually playing the game as instructed. Instead, friends and I would freely add pieces, complications, rules, and new wrinkles to the mouse trap itself before setting off the trap with glee.

I have plenty of fond memories solving (and designing) mechanical puzzles of all sorts. Unfortunately, I’ve been having a difficult time sparking the same interest in my nieces and nephews.

Sure, I’ve gotten them all hooked on LEGOs, which is a marvelous start for the tinkerer spirit, but more often than not, the kids would build the sets precisely as instructed, and then just leave them that way. No disassembly, no experimentation to build their own sets and ideas.

None of them have a bucket of random LEGO pieces made up from the fragments of a dozen or so disassembled sets, or know the joy of digging through the bucket laboriously in order to find the one perfect piece to finish a creation of their own design.

Thankfully, my cousin delivered the ideal solution as a gift for Nephew #3’s birthday, discovered by chance at Wal*Mart. The Smart Lab Weird & Wacky Contraption Kit.

This thing is great. The goal is to build a path from the top of a velcro-friendly wall to the bottom for a marble to traverse, traveling down slides and through obstacles of all sorts, in order to reach the landing pad at the bottom, which launches a spring-loaded celebratory pig into the air!

It’s similar to plenty of pipe-and-marble toys from years past, but with a lot more adaptability and flair, and it was an instant hit. Not only did every niece and nephew want a turn designing their own contraption, but they freely made suggestions (helpful and otherwise) for each other’s designs.

The best thing about it? When designs failed or the marble stalled, the kids didn’t get disheartened. It just encouraged them to try again and indulge their cleverness even further. It was a blast simply to watch.

And you better believe the adults got into it too, adding new wrinkles and complications to each contraption, and cheering just as loud when the pig was launched into the air after a successful run.

My cousin was roundly praised as king of the gift-givers that day, and I’ve been recommending the toy far and wide ever since. It’s a great mechanical puzzle and a fun time all at once. And it’s got a flying pig! What more could you want?
