# Tackling the GCHQ 2021 Christmas Card!

Every year, one of the puzzliest challenges many solvers will encounter all year descends upon the world, as the GCHQ issue their Christmas card.

The GCHQ — or Government Communications Headquarters — provides security and intelligence services for the British government. Back when they were known as GC&CS — Government Code and Cypher School — they were responsible for funding Bletchley Park and its successes cracking the German “Enigma” code during World War II.

This year’s Christmas card was directed toward solvers with a secondary school education (essentially solvers age 11 and up), and was less complicated than offerings in previous years, but still offered an engaging challenge.

Here’s the link in case you’d like to try it for yourself.

Last chance before we walk through the solution!

Okay, ready? Good! Let’s do this!

Clue number one is an easy one, as you simply read the first letter of each word in the message. Your solution is CHRISTMAS.

Clue number two is a simple 4×4 across-and-down grid where 1-Across and 1-Down are the same word, 2-Across and 2-Down are the same word, and so on. The completed grid reads:

T H I S
H O O T
I O W A
S T A G

And the letters in THIS are highlighted in the grid, so the solution is THIS.

Clue number three is a complete-the-sequence puzzle where the names of the Hogwarts houses from Harry Potter are listed, but each house in the sequence has more letters missing from the beginning and end of the word. Slytherin is the missing house, and with three letters missing from the beginning and end of the word, your solution is THE.

Clue number four is a Blackout! or Minesweeper-style puzzle where you deduce the location of bombs in the grid according to numbers in the neighboring squares. Once you’re marked off each of the bombs, the remaining spaces form letters and spell out a word. Your solution is SAFE.

Clue number five is a mnemonic device, and solvers must puzzle out what chain of related words is represented by the device. In this case, the major taxonomic ranks that are used to organize related living things are represented, and the word Kindly points toward the second word in the taxonomic ranks, so your solution is Kingdom.

Clue number six has three overlapping circles, each with letters inside, and you have to figure out not only what the words are, but what missing six-letter word would sit in the middle of this Venn diagram.

I found this to be the hardest puzzle in the card by far, as I tried and failed in numerous attempts to anagram the letters into recognizable words. Finally, I decoded the shortest word — LEEDS — only because I remembered that this is a British organization and I have friends who live in Leeds.

Leeds led me to unraveling the other two answers — MANCHESTER and NEWCASTLE — and my meager knowledge of European football provided the missing six-letter word. The solution is UNITED.

Clue number seven is a simple cryptogram, and is quickly decoded to read “This is the 7th question: people born between nineteen forty-six and nineteen sixty-four are commonly known as baby what?”

The solution appears to be BOOMERS, but there is an additional instruction to follow after decoding the message, and you must encode the answer. Following the same letter-substitution rule, BOOMERS becomes KEEPING, and that is your solution.

Now each word must be placed in order on the tree for your message to properly read out.

• The word BABY in clue 7 points toward the stroller icon, so our message begins with KEEPING.
• The lightning bolt icon refers to Harry Potter, so the word THE from clue 3 goes next.
• The soccer ball icon points to clue 6, so the word UNITED continues the message.
• The word KINGDOM from clue 5 aligns with the crown icon, so that’s our fourth word.
• The lock icon is most closely associated with SAFE from clue 4, so that’s next.
• At first, I thought the image of the Stag was a Harry Potter reference, but I then realized that STAG was one of the answers in clue 2’s grid, so this was the place for THIS.
• Finally, the present is the perfect spot for clue 1’s solution, CHRISTMAS.

And the message is revealed, celebrating the mission of the GCHQ itself: Keeping the United Kingdom Safe This Christmas.

# Solution to Last Week’s Merry Birthday Puzzle!

A week ago, we shared a brain teaser sent in by a PuzzleNationer named Darrin (who credited Marilynn Rapp Buxton as the creator of the puzzle). Darrin challenged us to solve the following logic puzzle.

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

Four friends — two girls named Holly and Joy, two boys named Kris and Noel — all celebrate their birthdays during December. Though none was born on Christmas Day — each was born on a different day — they all have festive names. Can you figure out each person’s last name and order of birth?

1. Nobody’s first name goes with the traditional last name (Berry, Fully, Kringle, or Singer) that you might expect.
2. Someone’s birthday is three days after their friend Joy’s birthdate.
3. Holly’s birthday is three days before Noel’s and three days after Kris’.
4. Miss Fully’s birthdate is six days after Joy’s.
5. Noel’s birthdate is six days after the one whose last name is Berry.

Let’s sort out the order of birth first.

We know from rule 3 that Holly’s birthdate is three days before Noel’s and three days after Kris’s. So their birthdate order is Kris, Holly, Noel.

But we also know from rule 2 that someone’s birthday is three days after Joy’s. Since they all have different birthdays, that means Joy’s birthday comes first in the order, giving us Joy, Kris, Holly, Noel.

Rule 4 tells us that Miss Fully’s birthdate is six days after Joy’s, so Holly’s last name is Fully.

Rule 5 states that Noel’s birthday is six days after the one whose last name is Berry, so Kris’s last name is Berry.

That gives us Joy ____, Kris Berry, Holly Fully, Noel ____.

Rule 1 tells us all four last names — Berry, Fully, Kringle, and Singer — and that nobody’s first name goes with the traditional last name that you might expect. Logically, those names would be Holly Berry, Joy Fully, Kris Kringle, and Noel Singer.

Since Kringle and Singer are the two remaining last names, and Singer can’t go with Noel, our final list reads Joy Singer, Kris Berry, Holly Fully, Noel Kringle.

When’s the last time you had your brain properly tied in knots by a riddle?

That’s a pretty common occurrence around here, honestly. In our puzzly explorations of the world, we stumble across all manner of brain teasers, riddles, logic puzzles, math problems, mind ticklers, deduction games, and wordplay-fueled bits of linguistic legerdemain.

Sometimes, we even receive them directly from our fellow PuzzleNationers!

And on those occasions, we happily share them with you, dear reader, so that you can also enjoy the challenge of unraveling whatever fiendish puzzly conundrum has been placed before us.

This time around, a solver named Darrin submitted this festive holiday puzzle he found in his aunt’s collection of puzzle books. (He credits Marilynn Rapp Buxton as the constructor of this puzzle.)

Let’s see how we do.

Four friends — two girls named Holly and Joy, two boys named Kris and Noel — all celebrate their birthdays during December. Though none was born on Christmas Day — each was born on a different day — they all have festive names. Can you figure out each person’s last name and order of birth?

# A Puzzle for Thanksgiving!

Happy Thanksgiving, PuzzleNationers!

Today is a day for celebrating with family and friends (although that’s harder this year), and giving thanks for all the good things in our lives.

We here at PuzzleNation want to thank you, our fellow puzzlers and PuzzleNationers, because you help make PuzzleNation one of the greatest puzzle communities in the world.

And when it comes to saying thanks, a Thanksgiving puzzle seems like the perfect offering. So we’ve cooked up a little Thanksgiving logic puzzle for you to enjoy!

Can you unravel this holiday puzzler?

On a curious Thanksgiving in 2020, five housemates were social distancing, each engaged in different activities throughout the day. (One was streaming Hulu.)

Each housemate (including Brian) wore a different outfit — one was wearing a tank top and shorts — and was doing their activity at a different time that day (1 PM, 2 PM, 2:30 PM, 3 PM, or 3:30 PM).

From the information provided, can you determine what time each housemate did which activity, as well as what outfit they were wearing?

1. The person doing Zoom trivia did so earlier than Alex but later than the one who wore a t-shirt and jeans.

2. Luke’s activity was earlier in the day than Denise’s, but later than that of the person who wore a Christmas sweater and pants.

3. Alex (who was wearing a Pokemon onesie) had her activity earlier than the person texting Grandma but later than Denise.

4. The person playing Among Us did so later than the person Facetiming their Mom, but earlier than the one wearing pajamas (who did their activity earlier than Adam).
