The World of Wooden Puzzles!

Posted on April 9, 2015 by gmdirect

Puzzles come in all shapes and sizes, adopting numerous forms that challenge the mind in seemingly endless ways.

While I spend a lot of time on PuzzleNation Blog talking about pen-and-paper puzzles (and their electronic siblings), today I’d like to focus on a brand of physical puzzles: ones made of wood!

As you’d expect, there are hundreds of different puzzles to choose from when discussing wooden puzzles, but I’ve tried to narrow the field down to a manageable size. Enough chatter, let’s get to it!

Sliding Tile Puzzles

[Available from FineWoodenToys.com.]

One of the oldest varieties of physical puzzles, sliding tile puzzles can be found in plastic, electronic, and wooden forms. And whether you’re shifting pieces in order to create a picture or pushing tiles around in order to put numbers in a specific order, the chain-solving technique is the same.

Tangrams

[Available from BrilliantPuzzles.com.]

A tactile and intuitive brand of puzzling, tangrams are a staple of the wooden puzzle market, utilizing simple geometric shapes in order to match designs or fit the pieces into a given space, as in the image above.

Brain Teasers

[Available from Mango Trees.]

These beautiful and elegant puzzles involve a level of craftsmanship and attention to detail that goes far beyond the usual mechanical puzzle experience.

Sometimes, you’re figuring out how to disassemble a shape into its component pieces (six examples of this sort of puzzle-solving appear above), while in others, you have to remove a given piece from a more complex arrangement, often involving ropes and other obstacles that interact with the wooden puzzle itself.

Puzzle Boxes

A practical sibling of the brain teasers above, a puzzle box offers an additional incentive to the solving experience, since puzzle boxes can make terrific delivery mechanisms for cash or other gifts. (Sometimes solving them involves only one step, other times it can involve a dozen or more!)

My younger sister has a habit of employing puzzle boxes like the one pictured below to make my oldest nephews work a little harder for their birthday money. (One particularly diabolical design involved concealed magnets holding the trick access point shut.)

Labyrinths

Everyone knows the goal of a maze or labyrinth: to get through it with as few wrong turns as possible. But when you have to navigate a steel ball through the labyrinth without falling into one of many pits, that becomes an even greater challenge.

Whether you’re using handles to manipulate the maze and allow gravity to shift the ball from point to point or turning the labyrinth this way and that in order to move the ball toward the finish line, your dexterity and patience are sure to be pushed to the limit.

Jigsaw Puzzles

I would be remiss if I ignored the most common variety of wooden puzzle: the jigsaw puzzle!

Whether we’re talking about the more traditional shapes in a Ravensburger puzzle or a jigsaw incorporating unique and interesting pieces like those produced by Wentworth or our friend Rachel Happen of Baffledazzle (like the ones pictured below), jigsaw puzzles are among the first puzzles to which a young child is exposed.

3-D Jigsaw Puzzles

Of course, despite the many tough jigsaw puzzles available these days, you might be looking for a jigsaw with an additional dimension of difficulty. Thankfully, there are 3-D puzzles to give your spatial reasoning a run for its money!

Both the dragon at the top of the page and the camel pictured above are 3-D puzzles that were sent to me by the lovely Sara Kingsland, owner of Completely Puzzled in Port Townsend, Oregon.

And let me tell you, these puppies put my jigsaw skills to the test. Let’s look at the camel disassembled:

Is it immediately clear to you how to proceed? It certainly wasn’t to me! Now let’s look at the dragon disassembled:

Believe it or not, I solved the dragon before the camel!

This is because the puzzles involve different approaches. The dragon was designed to be assembled from tail to head, and rarely required me to hold more than two pieces at a time to continue solving it.

The camel, on the other hand, has to be solved legs first, which means holding numerous pieces in place while manipulating others in order for everything to come together.

With the advent of laser printing, the sky is truly the limit when it comes to imagining new and challenging wooden puzzles. I can’t wait to see what these wickedly brilliant puzzlers come up with next.

Are there any types of wooden puzzle I missed, fellow puzzlers and PuzzleNationers? Let me know! (Other than Scrabble, that is. I left that one off the list intentionally.) And while you’re at it, tell me what your favorite kind of wooden puzzle is!

Puzzles in Pop Culture: Brooklyn Nine-Nine

Posted on March 24, 2015 by gmdirect

In previous editions of Puzzles in Pop Culture, we’ve explored opinions about crosswords, embarked on scavenger hunts with sitcom characters, and even saved New York with brain teasers alongside John McClane in Die Hard with a Vengeance. But it’s rare when a movie or TV show poses a puzzler and leaves it to the audience to solve it.

In “Captain Peralta,” a recent episode of the Fox police sitcom Brooklyn Nine-Nine, a subplot featured Captain Holt posing a brain teaser to his fellow officers.

There are 12 men on an island. 11 weigh exactly the same amount, but one of them is slightly lighter or heavier. You must figure out which.

The island has no scales, but there is a seesaw. You can only use it three times.

With Beyonce tickets going to the person who solved the puzzle, the competition was fierce. Rosa suggested using the seesaw to threaten the men into confessing. Amy and Terry suggested that the first seesaw ride involve putting six men on one side and six on the other, which Captain Holt quickly said wouldn’t work.

As it turns out, Holt was hoping one of his officers would solve the puzzle for him, since he’s been unable to crack it for years. The episode ended without providing the audience with a solution.

Thankfully, your friends here at PuzzleNation Blog would never leave you high and dry like that. Let’s get puzzling!

Now, this WOULD be a simple logic problem if you knew you were looking for someone lighter or you knew you were looking for someone heavier. In that case, a 3×3 ride, 4×4 ride, or even the 6×6 ride Amy and Terry suggested, would eliminate part of the field immediately, and the remaining two uses could determine the heavy person or the light person.

Unfortunately, in Captain Holt’s puzzle, you don’t know if the person is heavier or lighter, which makes this more difficult. For instance, if you knew you were looking for someone heavier, you could immediately eliminate anyone on the side of the seesaw higher in the air. But if you don’t know if the subject in question is lighter or heavier, then you could have a heavier person on one side or a lighter person on the other.

Diabolical.

But, with some careful deduction, you CAN solve this puzzle.

First, let’s identify our 12 castaways with the letters A through L. Now let’s divide them into three groups of four: ABCD, EFGH, and IJKL.

seesaw

For the first seesaw ride, let’s weigh ABCD vs. EFGH.

There are three possible outcomes:

They balance, meaning we can eliminate all eight of them and our mystery person is in IJKL.
ABCD sinks while EFGH rises, meaning there’s a heavier person in ABCD or a lighter person in EFGH, so we can eliminate IJKL.
EFGH sinks while ABCD rises, meaning there’s a heavier person in EFGH or a lighter person in ABCD, so we can eliminate IJKL.

OUTCOME 1: They balance

For the second seesaw ride, we’ll take IJK and weigh them against any three of the eliminated people — let’s say ABC — because we know they weigh the same.

OUTCOME 1-1: if IJK balances against ABC, we know that L is our guy. For the third seesaw ride, weigh L against A to determine if L is lighter or heavier.

OUTCOME 1-2: if IJK sinks, one of them is heavier than ABC. For the third seesaw ride, weigh I against J. If they balance, K is the heavy one. If I or J sinks, he’s the heavy one.

OUTCOME 1-3: if IJK rises, one of them is lighter than ABC. For the third seesaw ride, weigh I against J. If they balance, K is the light one. If I or J rises, he’s the light one.

article-2401231-1b6471bd000005dc-74_634x452

OUTCOME 2: ABCD sinks while EFGH rises

For the second seesaw ride, we have eight possible suspects — four heavy, four light — so we mix up the two previous groupings in order to eliminate some suspects. We’ll take E, F, and A and weigh them against G, B, and L. That’s two from the lighter side and one from the heavier vs. one from the lighter, one from the heavier, and one we know is standard.

Again, there will be three possible outcomes:

OUTCOME 2-1: If EFA balances with GBL, they’re all eliminated, leaving either H as a lighter person or either C or D as a heavier person. For the third seesaw ride, weigh C against D. If they balance, H is lighter. If they don’t, whichever is heavier is our guy.

OUTCOME 2-2: If EFA sinks, either A is heavy (because E and F were on the lighter side before) or G is light (because B was on the heavier side and L has already been eliminated), and we can eliminate C, D, and H. For the third seesaw ride, weigh G against L. If they balance, A is heavy. If they don’t, then G is light.

OUTCOME 2-3: If EFA rises, either B is heavy (because G was on the lighter side and L has already been eliminated) or either E or F is light (because A was on the heavier side), and we can eliminate C, D, and H. For the third seesaw ride, weigh E against F. If they balance, then B is heavy. If they don’t, whichever is lighter is our guy.

OUTCOME 3: EFGH sinks while ABCD rises

For the second seesaw ride, we have eight possible suspects — four heavy, four light — so we mix up the two previous groupings in order to eliminate some suspects. We’ll take A, B, and E and weigh them against C, F, and L. That’s two from the lighter side and one from the heavier vs. one from the lighter, one from the heavier, and one we know is standard.

Again, there will be three possible outcomes:

OUTCOME 3-1: If ABE balances with CFL, they’re all eliminated, leaving either D as a lighter person or either G or H as a heavier person. For the third seesaw ride, weigh G against H. If they balance, D is lighter. If they don’t, whichever is heavier is our guy.

OUTCOME 3-2: If ABE sinks, either E is heavy (because A and B were on the lighter side) or C is light (because F was on the heavier side and L has already been eliminated), and we can eliminate D, G, and H. For the third seesaw ride, weigh C against L. If they balance, E is heavy. If they don’t, then C is light.

OUTCOME 3-3: If ABE rises, either F is heavy (because B was on the lighter side and L has already been eliminated) or either A or B is light (because E was on the heavier side), and we can eliminate D, G, and H. For the third seesaw ride, weigh A against B. If they balance, then F is heavy. If they don’t, whichever is lighter is our guy.

This was one whopper of a brain teaser, to be sure, and I’m not surprised it stumped even the likes of the impressive Captain Holt. But, as a special treat, if you’d like to see the Captain himself explain the solution, go here and check out the embedded video. Enjoy.

Of course, it doesn’t answer the real question: who cares about weight? Why aren’t they building a boat to escape the island?

A Puzzle in Honor of Leonard Nimoy

Posted on March 3, 2015 by gmdirect

Late last week, news went out that actor, sci-fi luminary, and respected advocate for science Leonard Nimoy had passed away. As a fan of much of his work — not just Star Trek, but Fringe, In Search Of…, and numerous other shows made better by his presence — I was sad to say goodbye to such a terrific and influential figure.

And so, I thought it was only appropriate to honor him in true PuzzleNation fashion: with a Star Trek-themed brain teaser.

This puzzle was created by a University of Kentucky mathematician and puzzler named Raphael Finkel, and came to my attention thanks to a post on IO9.com. It’s a logic puzzle that will really test your deduction skills, perfect to honor pop culture’s most famous Vulcan and their great tradition of logic and reason.

Six Fearsome Heroes

Grobly Grizik is planning to write a novel fashioned after Star Trek: The Next Generation. In this novel, six of the crew members compete both at Fizzbin and at Tri-Dimensional chess. Each crew member gets two independent rankings for proficiency at these games (one ranking for each game), with “1” ranked lowest and “6” highest.

Every crew member has a personal hero among the crew, and every crew member is afraid of some crew member. Everyone is the hero of somebody, and everyone is feared by somebody. Nobody either fears him/herself nor counts him/herself as a hero. Nobody fears his/her own hero.

From the given clues, discover every crew member’s ranking at Fizzbin and at Tri-D chess, as well as whom he/she fears and whom he/she counts as a hero:

Geordi ranks 2 at Tri-D Chess.
Picard ranks two positions behind Troi at Fizzbin.
Troi is feared by the person Geordi fears.
Worf’s hero ranks 3 times lower at Tri-D Chess than the crew member who is best at Fizzbin.
Picard’s hero fears Geordi.
Data’s hero is not Geordi.
Data is the hero of Riker’s hero.
The person who is worst at Fizzbin is better than Troi at Tri-D Chess.
The person ranked number 3 at Tri-D Chess is ranked 4 positions higher than Data at Fizzbin.
Riker is feared by the person Picard fears and is the hero of Worf’s hero.
Riker is ranked 2 lower at Tri-D Chess than the crew member ranked 2 at Fizzbin.

Let us know if you solve this diabolical puzzle. And please share your favorite Nimoy roles and memories. He was a remarkable talent and will be missed.

It’s Follow-Up Friday: Hats Off to You edition!

Posted on December 12, 2014 by gmdirect

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’d like to revisit the subject of brain teasers.

A few years ago, we posted a riddle that had been making the rounds online. It centered around four men buried up to their necks in the ground, each one trying to figure out what color hat he is wearing.

It’s a great exercise in logic and deduction, one that most solvers unraveled after a few minutes.

As it turns out, there’s a more complex version of this riddle. But this one involves 100 people!

One hundred prisoners are lined up single file, facing in the same direction. Each prisoner will be randomly assigned either a red hat or a blue hat.

No one can see the color of his own hat. However, each person is able to see the color of the hat worn by every person in front of him. So the person at the head of the line cannot see the color of anyone’s hat, the second prisoner can see only the first prisoner’s hat, the third can see the first two prisoners’ hats, and so on. The last person in line — the 100th prisoner — can see the colors of the hats on all 99 people in front of him.

Beginning with the last person in line, and then moving to the 99th person, the 98th, etc., each will be asked to name the color of his own hat. If the color is correctly named, the person lives; if incorrectly named, the person is shot dead on the spot.

Everyone in line is able to hear every response as well as hear the gunshot; also, everyone in line is able to remember all that needs to be remembered and is able to compute all that needs to be computed.

Before being lined up and given their hats, the 100 prisoners are allowed to discuss strategy, with an eye toward developing a plan that will allow as many of them as possible to name the correct color of his or her own hat (and thus survive). They know all of the preceding information in this problem. Once lined up, each person is allowed only to say “Red” or “Blue” when his turn arrives, beginning with the last person in line.

What would your plan be to save as many people as possible? How many prisoners can you definitely save?

It’s an absolutely diabolical riddle, one that definitely taxed my puzzle skills. And different plans have different chances for success! Will you save half? 75%? Can you save everyone?

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’d like to return to the subject of riddles and brain teasers!

We’ve featured plenty of them on the blog over the years, from this Parking Lot puzzler to Lewis Carroll’s most infamous riddle. But it never occurred to us to test our riddle-solving and brain-teasing skills under the influence of a few glasses of wine.

Thankfully, Sudoku enthusiast and YouTuber Hannah Hart (of My Drunk Kitchen fame) took it upon herself to ask her fans to submit riddles for her to unravel while tipsy.

Did you figure them out faster than Hannah? Do you think a glass of wine would help your puzzling? (Or perhaps I should ask “do puzzles drive you to drink?” *laughs*)

Since people were submitting more riddles for her to solve, I couldn’t resist tossing in one of my own:

Four jolly men sat down to play,
And played all night till break of day.
They played for cash and not for fun,
With a separate score for every one.
When it came time to square accounts,
they all had made quite fair amounts.
Now, not one has lost and all have gained –
Tell me now, this can you explain?

A little something to keep you busy on this lovely Friday. Enjoy.
