Answers to our Thanksgiving Logic Puzzle!

It’s been a week since Thanksgiving, so it’s about time we gave you the answer to our Turkey Day logic puzzle!

In case you missed it, here’s the puzzle:

Connor, Emma, Russell, and Taylor are celebrating Thanksgiving together. To save money, each of them is bringing a different side dish (cranberry sauce, green beans, mashed potatoes, or yams). Each of them is also bringing a different dessert (apple pie, chocolate cream pie, pumpkin pie, or sugar cookies). With the help of the clues below, can you puzzle out who brought which side dish and which dessert?

1. Emma didn’t bring the green beans, but she did bring pumpkin pie.
2. Connor brought the cranberry sauce, but he didn’t bring chocolate cream pie or apple pie.
3. The person who brought the yams also brought the chocolate cream pie.
4. Taylor brought the green beans.


Okay, last chance to solve it before we give you the solution!

Here we go!


Now, this isn’t as difficult as some of the diabolical brain teasers we’ve tackled in the past, but for someone new to logic puzzles and deduction, a puzzle like this can be daunting.

The key to logic puzzles is to organize your information in a simple and efficient way, so that you maximize the amount of information you glean from each clue.

So let’s list out our four holiday guests and all of the possible food options.

Now, let’s proceed through the clues and fill in our chart.

1. Emma didn’t bring the green beans, but she did bring pumpkin pie.

Since we know nobody brought the same dessert as Emma, we can black out pumpkin pie for everyone else, as well as blacking out the other dessert options for Emma, since each person only brought one dessert.

2. Connor brought the cranberry sauce, but he didn’t bring chocolate cream pie or apple pie.

When you add Connor’s info to Emma’s, you not only get his side dish and his dessert, since he didn’t bring chocolate cream pie, apple pie, or Emma’s pumpkin pie.

3. The person who brought the yams also brought the chocolate cream pie.

At first, this clue doesn’t seem to tell us much, because we don’t know who brought the yams or the chocolate cream pie. But we do know that Emma didn’t bring the chocolate cream pie, so she didn’t bring the yams either.

And if she didn’t bring the yams, the green beans, or Connor’s cranberry sauce, by process of elimination, she brought the mashed potatoes.

4. Taylor brought the green beans.

This last clue ties it all together. If Taylor brought the green beans, then Russell had to bring the yams. And since the person who brought the yams brought the chocolate cream pie, we know that was Russell as well, and Taylor brought the apple pie by default.

And there you have it. All that info in four simple clues.

We hope you enjoyed our little Thanksgiving logic puzzler!

Cracking the GCHQ Christmas Card!

As you may recall, my fellow puzzlers and PuzzleNationers, a few months ago, a government organization in England called the GCHQ — Government Communications Headquarters — released a puzzly Christmas card designed to tax even the savviest puzzle solvers.

They’ve finally released the answers to this mind-blowing series of puzzles, and I’d like to go over some of them with you. Partly to marvel at the puzzle wizardry necessary to solve this challenging holiday gift, and partly to gloat about the parts I managed to solve.

So let’s get to it!


Part 1 was a logic art puzzle where you have to deduce where to place black squares on an open grid in order to form a picture.

Each column and row has a series of numbers in it. These numbers represent runs of black squares in a row, so a 1 means there’s one black square followed by a blank square on either side and a 7 means 7 black squares together with a blank square on either side.

This is mostly a deduction puzzle — figuring out how to place all the strings of black squares with white spaces between them within the space allotted — but no image immediately emerged, which was frustrating. Once the three corner squares started to form though, I realized the answer was a QR code, and the puzzle started to come together nicely.


Part 2 was a series of six multiple-choice brain teasers. I’ll give you the first three questions, along with answers.

Q1. Which of these is not the odd one out?

A. STARLET
B. SONNET
C. SAFFRON
D. SHALLOT
E. TORRENT
F. SUGGEST

Now, if you stare at a list of words long enough, you can form your own patterns easily. Here’s the rationale the GCHQ used to eliminate the odd ones out:

STARLET is an odd one out because it does not contain a double letter.
SONNET is an odd one out because it has 6 letters rather than 7.
SAFFRON is an odd one out because it ends in N rather than T.
TORRENT is an odd one out because it starts with T rather than S.
SUGGEST is an odd one out because it is a verb rather than a noun.

SHALLOT is our answer.

Q2. What comes after GREEN, RED, BROWN, RED, BLUE, -, YELLOW, PINK?
A. RED
B. YELLOW
C. GREEN
D. BROWN
E. BLUE
F. PINK

After playing around with some associative patterns for a while, I realized that somehow these colors must equate to numbers. First I tried word lengths, but 5-3-5-3-4-___-6-4 didn’t make any sense to me. But then, it hit me: another time where colors and numbers mix.

Pool balls. Of course, the colors and numbers didn’t match, because this is a British puzzle, and they don’t play pool, they play snooker.

So the colored balls in snooker become the numbers 3, 1, 4, 1, 5, -, 2, 6. The numbers of Pi. And now the blank makes sense, because Pi reads 3.1415926, and there’s no 9 ball in snooker.

So the next number in the chain is 5, and 5 is the color BLUE.

Q3. Which is the odd one out?
A. MATURE
B. LOVE
C. WILDE
D. BUCKET
E. BECKHAM
F. SHAKA

This one came pretty quickly to me, as the names Oscar Wilde and Charlie Bucket leapt out. And if you follow the phonetic alphabet, you also get Victor Mature, Romeo Beckham, and Shaka Zulu. (I didn’t get Mike Love, however.)

Since Shaka Zulu was the only one where the phonetic alphabet word was the surname, not the first name, SHAKA is the odd one out.

(The other three questions included an encryption puzzle, a number pattern (or progressions puzzle), and a single-letter puzzle.)

Granted, since you could retake this part as many times as you wanted, you could luck your way through or brute force the game by trying every permutation. But managing to solve most of them made this part go much faster.


Part 3 consisted of word puzzles, and was easily my favorite section, because it played to some strengths of mine.

A. Complete the sequence:

Buck, Cod, Dahlia, Rook, Cuckoo, Rail, Haddock, ?

This sequence is a palindrome, so the missing word is CUB.

B. Sum:

pest + √(unfixed – riots) = ?

This one is a little more involved. To complete the formula, you need to figure out what numbers the words represent. And each word is an anagram of a French number. Which gives you:

sept + √(dix-neuf – trois) = ?

Dix-neuf is nineteen and trois is three, so that’s sixteen beneath a square root sign, which equals four. And sept (seven) plus four is eleven.

The French word for eleven is onze, and ZONE is the only anagram word that fits.

C. Samuel says: if agony is the opposite of denial, and witty is the opposite of tepid, then what is the opposite of smart?

This is a terrific brain teaser, because at first blush, it reads like nonsense, until suddenly it clicks. Samuel is Samuel Morse, so you need to use Morse Code to solve this one. I translated “agony” and tried reversing the pattern of dots and dashes, but that didn’t work.

As it turns out, you need to swap the dots and dashes, and that’s what makes “denial” read out. This also worked with “witty” and “tepid,” so when I tried it with “smart,” the opposite was OFTEN.

D. The answers to the following cryptic crossword clues are all words of the same length. We have provided the first four clues only. What is the seventh and last answer?

1. Withdraw as sailors hold festive sing-song
2. It receives a worker and returns a queen
3. Try and sing medley of violin parts
4. Fit for capture
5.
6.
7. ?

Now, I’m not a strong cryptic crossword solver, so this part took FOREVER. Let’s work through it one clue at a time.

1. Withdraw as sailors hold festive sing-song

The word WASSAIL both reads out in “withdraw as sailors hold” and means “festive sing-song.”

2. It receives a worker and returns a queen

The word ANTENNA both “receives” and is formed by “a worker” (ANT) and “returns a queen” (ANNE, reading backward).

3. Try and sing medley of violin parts

The word STRINGY is both an anagram of “try” and “sing” and a violin part (STRING).

4. Fit for capture

The word SEIZURE means both “fit” and “capture.”

Those four answers read out like this:

WASSAIL
ANTENNA
STRINGY
SEIZURE

And with three more answers to go, it seemed only natural that three more seven-letter answers were forthcoming. Plus, when you read the words spelling out downward, you notice that the first four letters of WASSAIL, ANTENNA, STRINGY, and SEIZURE were spelling out.

If you follow that thought, you end up with the start of a 7×7 word square:

 WASSAIL
ANTENNA
STRINGY
SEIZURE
ANNU___
INGR___
LAYE___

And the only seven-letter word starting with INGR that I could think of was INGRATE.

WASSAIL
ANTENNA
STRINGY
SEIZURE
ANNU_A_
INGRATE
LAYE_E_

And if the last word is LAYERED…

WASSAIL
ANTENNA
STRINGY
SEIZURE
ANNU_AR
INGRATE
LAYERED

Then the missing word must be ANNULAR. The original question asked for the last word though, so our answer is LAYERED.


This brings us to Part 4, Number Puzzles, where I must confess that I finally tapped out, because I could only figure out the first of the three progressions involved.

Fill in the missing numbers.

A. 2, 4, 8, 1, 3, 6, 18, 26, ?, 12, 24, 49, 89, 134, 378, 656, 117, 224, 548, 1456, 2912, 4934, 8868, 1771, 3543, …

B. -101250000, -1728000, -4900, 360, 675, 200, ?, …

C. 321, 444, 675, 680, 370, 268, 949, 206, 851, ?, …

In the first one, you’re simply multiplying by 2 as you go.

2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072, 262144, and so on.

But you begin to exclude every other number as you move into double-digits, triple-digits, quadruple-digits, and beyond.

2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072, 262144, and so on.

So the answer, 512, becomes the real answer, 52.

But, as I said, I couldn’t crack the other two, and I’m already exhausted just running through these four sections!

And, based on the answers they released recently, Part 5 only got more mindbending from there.

As a matter of fact, not a single entrant managed to get every answer in Part 5 correct. Prizes were awarded to the three people who came closest however, and it turns out a staggering 30,000+ people made it to Part 5. Color me impressed!

This was, without a doubt, the most challenging puzzle suite I have ever seen, and I offer heartfelt kudos to anyone in the PuzzleNation Blog readership who even attempted it!

You’re welcome to try it out for yourself, though. I highly recommend using this link from The Telegraph, which allows you to skip to the next part if you get stumped.

It’s Follow-Up Friday: Single Letter 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’ll be posting the answers to the single letter puzzles from Tuesday’s blog post all about the power of single letters in puzzles!

The first puzzle was a brain teaser.

There’s a word in the English language in which the first 2 letters signify a male, the first 3 signify a female, the first 4 signify a great man, and the whole word signifies a great woman. What is that word?

The word is HEROINE. The first two letters are HE, the first three are HER, and the first four are HERO.


The second puzzle involved the first letters of words forming a pattern, and I asked you to both deduce the pattern and provide the next entry in the series.

O, T, T, F, F, S, S, E, ?

The next entry in the series is N, for Nine. These are the first letters of numbers — One, Two, Three, Four, Five, Six, Seven, Eight.

J, F, M, A, M, J, J, A, S, O, N, ?

The next entry in the series is D, for December. These are the first letters of the months of the year.

S, M, H, D, W, M, ?

The next entry in the series is Y, for Year. These are the first letters for increasing lengths of time — Second, Minute, Hour, Day, Week, Month.

M, V, E, M, J, S, U, ?

The next entry in the series is N, for Neptune. These are the first letters of the planets in the solar system, from closest to the sun to furthest from it.

D, K, P, C, O, F, G, ?

The next entry in the series is S, for Species. These are the first letters of the classification system for all life on Earth — Domain, Kingdom, Phylum, Class, Order, Family, Genus.


The third and final puzzle involved the first letters of words, but with numbers added, and I asked you to deduce what the letters represent.

3 F in a Y: 3 feet in a yard

366 D in a LY: 366 days in a leap year

12 S in the Z: 12 signs in the Zodiac

4 Q in a D: 4 quarters in a dollar

13 C in a S: 13 cards in a suit


How did you do? Did you solve them all, or did these crafty single letter puzzles stump you?
