Tougher than 99% of solvers? I think not.

A friend on Facebook sent me this link to a quiz that claims being able to solve the following brain puzzles puts your IQ in the Top 1%.

The Top 1% of what, I have no idea. But I digress.

I can’t resist a brain teaser, especially one with such a lofty premise, so I clicked the link and accepted the challenge.

And I feel confident saying that, except for one question, I firmly believe every PuzzleNationer in the audience could conquer these “brain puzzles” effortlessly.

To be fair, I have good reason to feel confident going into this challenge, because the example was the parking lot puzzle we featured on the Blog years ago.

And thus, I clicked and ventured forth into the realm of supposed geniuses.

The first question asked that we count the number of Fs in a sentence, counting on the tendency of people to miss Fs in small words like “of.” No problem here.

The second question offered a brain teaser classic, asking us to count how many squares are in this grid:

[I’m sure you’ve seen this one before.]

The third was a brain teaser, one of those calendar-based ones like “If today is Thursday’s yesterday’s yesterday’s yesterday, how many days away is Friday?” No sweat.

Then there were some optical illusions, visual manipulation, and spacial awareness puzzles, like what would such-and-such look like if this happened. That sort of thing. Easy-peasy.

But then the quiz took a strange turn. It asked what you saw first in a picture containing with several images. (It’s like that picture of the old woman and the young woman, asking which you saw first. It’s a really odd question under the circumstances.)

Then, as advertised, the parking lot puzzle showed up.

The last one was the only real challenge. You were given a six-by-six grid full of symbols — black clubs and spades from playing cards, plus red hearts, diamonds, and squares, some upright, some upside-down — with one square empty. And you had to pick which symbol fit the empty space.

I confess, I haven’t yet cracked this one, but apparently my guess — upside-down spade — was good enough to merit the following response:

Based on this assessment, your intelligence is extremely advanced. You are a genius with a near-perfect IQ. You have an incredible mastery of both analytical AND abstract thought processes. You are very number-orientated and have strong mathematical and logic skills.

And on the other hand, you have a avid imagination and the keen ability to think outside of the box. Your core capacities include mental imagery, spatial reasoning, image manipulation, and strong artistic skills. As evident by this test, you are excellent at solving puzzles. You will most likely succeed in technical, scientific, or mathematical fields.

Now, I understand that most of these quizzes exist to make you feel smart and/or give you something positive to post on Facebook and share with friends and family.

That being said, this is hardly a challenge that would exclude 99% of solvers. In fact, my fellow PuzzleNationers, considering some of the brain teasers we’ve tackled together, I think we’re all justified in posting that victory text on Facebook. I have no doubt that we’ve all earned it.

It’s Follow-Up Friday: LEG-OH NO WAY 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.

It’s been quite a week here at PuzzleNation Blog!

After posts that ran the gamut from Comic-Con encryption puzzles and new puzzle sets for the Penny Dell Crosswords app to becoming a sharper Hangman or Guess Who? player and enjoying the puzzly chain reactions known as Rube Goldberg devices, I was left with quite a conundrum: How do I close out such an eclectic week?

This will be my sixth post in six days after all. What would be an appropriate capper?

Well, I think I found the perfect Friday post idea: some visual LEGO puzzle wizardry.

Specifically, it’s a moving piece of puzzle art that combines the visual wonder of the pop-up book with the puzzly skill of a LEGO master builder.

I give you the LEGO Pop-Up Himeji Castle:

I’ve watched the video over and over, and I have no idea how the castle fits together OR compresses itself flat enough to fit between the “covers.” This is mind-blowing LEGO skill and puzzly three-dimensional manipulation of space.

And apparently, this sort of next-level three-dimensional spatial reasoning is second-nature to YouTuber Talapz, since he also managed to create this multi-dimensional sculpture that allows a ball to traverse it in three different arrangements:

I first stumbled across Talapz’s works on this site (written in French, no less!), and quickly followed his work on his YouTube page. Be sure to click the link for more brain-melting works of puzzly LEGO art.

Rube Goldberg Overload!

A Rube Goldberg machine, for the uninitiated, is a device designed to accomplish a simple task in as many unnecessary, ludicrous steps as possible. The name comes, appropriately enough, from Rube Goldberg, a cartoonist and inventor most famous for his cartoons featuring singularly silly and elaborate machines like the one pictured below.

We’ve posted videos of Rube Goldberg machines in the past, because they’re a perfect example of a mechanical puzzle in action. Only when things happen in a precise order does the machine complete its task.

And they’ve been around long enough that we’re starting to see fun variations on the concept. Beyond simply accomplishing a task, many Rube Goldberg devices tell stories or center around a given theme. (We even featured one that was designed to take weeks to complete!)

And today, I’ve got four videos of Goldbergian goodness to share with you.

First off, another terrific entry from Purdue University. The school has really made a name for itself in the Rube Goldberg field over the last few years, and perhaps my favorite device of theirs is this record-setting machine charting the progression of human history:

From human history to racing history, we now turn our attention to this car part-themed device from the team at Arrow FiveYearsOut, complete with an unexpectedly zippy finale:

When it comes to devices with many moving parts in complex interactions, it’s hard to top watches with their myriad of miniature gears, wheels, and other intricate details.

So it should come as no surprise that Seiko has gotten into the Rube Goldberg spirit with their own timepiece-themed device, “The Art of Time.” Involving over 1,200 individual watch pieces, this might be the smallest, most elegant Rube Goldberg device I’ve ever seen:

And finally, we have my favorite of my recent discoveries. This video from YouTuber Kaplamino has been making the rounds on Facebook — uncredited, unfortunately — and it’s a marvel. It’s entitled “Magnets and Marbles,” but should really be called “Magnets and Marbles and Momentum and a Metric Buttload of Patience.”

Built on a tilted table, “Magnets and Marbles” is not a true Rube Goldberg device — there was never one complete uninterrupted run — but it remains a thoroughly impressive design.

According to the creator, “Each screen was recorded separately, and even like that, some of them only work 10% of the time. I can’t give you a number because I didn’t count the fails, but I think it’s over 100.”

Nonetheless, the clever use of magnets makes this one of the most dynamic and creative machines I’ve seen in quite a while:

Rube Goldberg devices are only growing more ambitious, audacious, and creative, and I cannot wait to see what people come up with next.

Better Gaming With Math and Statistics!

[Image courtesy of ThreeSixtyOne.gr.]

Statistical analysis is changing the world. The wealth of available data on the Internet these days, combining with our ever-increasing ability to comb through that data efficiently using computers, has spawned something of a golden age in data mining.

You don’t need to look any further than the discovery of Timothy Parker’s plagiaristic shenanigans for USA Today and Universal Uclick to see how impactful solid analysis can be.

But it’s also having an impact on how we play games. Statistical analysis is taking some of the mystery out of games you’d never expect, making players more efficient and capable than ever.

We discussed this previously with the game Monopoly — specifically how some spaces are far more likely to be landed on than others — and today, we’re looking at two more examples: Guess Who? and Hangman.

Guess Who? gives you a field of 24 possible characters, and you have to figure out which character your opponent has before she figures out the identity of your character. Usually, if you end up with a woman or someone with glasses, your odds of winning are low, because some aspects are simply less common than others.

But is there an optimal way to pare down the options? Absolutely.

Mathematician Rafael Prieto Curiel has devised a strategy for playing Guess Who?, based on an analysis of the notable features of each character, breaking it down into 22 possible questions to ask your opponent:

Based on this data, he has even created a flowchart of questions to ask to maximize your chances of victory. The first question? “Does your person have a big mouth?”

Yes, not exactly a great first-date question, but one that yields the best possible starting point for you to narrow down your opponent’s character.

It’s certainly better than my first instinct, which is always to ask, “Does your person look like a total goon?”

Now, when it comes to Hangman, the name of the game is letter frequency. Just like a round of Wheel of Fortune, you’re playing the odds at first to find some anchor letters to help you spell out the entire answer.

But, as it turns out, letter frequency is not the same across all word lengths. For instance, E is the most common letter in the English language, but it is NOT the most common letter in five-letter words. That honor belongs to the letter S.

In four-letter words, the most common letter is A, not E. And it can change, depending on the presence — or lack thereof — of other letters.

From How to Win Games and Beat People by Tom Whipple:

“E might be the most common letter in six-letter words, and S the second most common, but what if you guess E and E is not in it?” In six-letter words without an E, S is no longer the next best letter to try. It is A.

In fact, Facebook data scientist Nick Berry has created a chart with an optimal calling order based on the length of the blank word.

For one-letter words through 4-letter words, start with A. For five-letter words, start with S. For six-letter words through twelve-letter words, use E. And for words thirteen letters and above, start I.

Of course, if you’re the one posing the word to be guessed, “jazz” is statistically the least-likely word to be guessed using this data. And your opponent will surely hate you for choosing it.
