Kominers’s Conundrums: A Puzzle in Honor of Mothers Everywhere
(Bloomberg Opinion) -- Happy Mother’s Day! Here at Conundrums, we’re celebrating in our customary way: A puzzle honoring moms everywhere, including yours and mine.
The clues below describe common words — many of them “mother” or “spring” themed. Your goal is to figure out what they are. To help you check your answers, we’ve made sure that each clued word would also make sense if put together with some of the words at the end of the clue text.
So for example, “This gem is one you might say an oyster is the mother of (5)” could be cluing “PEARL,” which fits with “mother of” to make the phrase “mother of PEARL.”
The first number in parentheses following each clue indicates the number of letters in the answer.
But that’s not all. We’ve also given two other numbers for each clue, separated by a comma. Those indicate two letters that you should pull out of each answer word. What do you do with those letters? Using half of them — one from each answer — you should be able to spell out this week’s answer, which is a trait shared by our favorite mothers around the world.
But which letters should you choose from each pair? That you’ll have to puzzle out for yourself!
- What it takes to stand up for what your compass tells you is solidly moral (7 | 3,5)
- A place where you shouldn’t leave toys, lest people crossing from room to room trip on the mess (4 | 3,4)
- Place in New York where theatrical performers put their shows on (8 | 4,6)
- Stem tuber, or a kid who spends too much time on the couch (6 | 3,4)
- Type of board that serves a company in a role that’s almost parental (8 | 4,8)
- Some aspire for their children to be this kind of artist, whom you might hear at a Billy Joel concert (7 | 1,6)
- Revolutionary 1950s-60s Court, or burrow for a rabbit (6 | 3,4)
- Sendak’s Kithen, or a time when you might ask your parents to read one more story if they give you an opening (5 | 1,2)
- Waterfowl Bostonians might have to make way for (9 | 3,8)
- Our planet, which we sometimes call “mother” (5 | 2,5)
- What mothers know — every day, and especially this Sunday (4 | 3,4)
As you work through the clues, don’t forget to be on the lookout for patterns and possible meanings among the indicated letters — you might be able to figure out the answer to the full Conundrum without solving every individual clue.
(And what to make of those letters you don’t use in the overall answer? You might want to hang onto them for use in the future.)
If you manage to make sense of this Mother’s Day mystery — or if you even make partial progress — please let us know at email@example.com before midnight New York time on Thursday, May 13.
Programming note: The next Conundrums will run on May 16.
Previously in Kominers’s Conundrums…
For Star Wars Day (May the “Fourth” be with you!), we had to figure out the secret weak point of the Empire’s new Death Star. Rebel agent “Zigzag” managed to get ahold of the information, but unfortunately it was encrypted — as were most of the decryption instructions.
The first instruction was “SHIFT ALL LETTERS BACK ONE SPACE,” and as we indicated in the Conundrum itself, applying that transformation to the second instruction gave “DROP LETTERS IN NAME OF BOUNTY HUNTER WHO CAPTURED HAN SOLO. THEN DECRYPT WITH MORSE CODE; X MARKS THE DOT.”
YXX EBFTATAFBBTYYYFAE / FTFYYY XYXO BBA / BTTB EABABBTTAOTFAFBABBYXXBAFABBBBF TOOAYYYTTTTTTBAB / BYXATOE ATFEYYY TTYAABB!
… to a much shorter one:
YXX YYY / YYY XYX / YXX YYY / YX YYY Y!
DO OR DO NOT!
This instruction, of course, is classic Star Wars lore — Yoda’s admonition to “Do or do not, there is no try.”
But looking at the fourth instruction, you could see it was quite far from having “no try” — indeed, the word “TRY” seems to be everywhere:
UTRYSE TRYTHTRYE TRYFTRYORTRYCTRYTRYE TRYTRYETRYQTRYUATRYTITRYON;TRYTRYTRY THTRYENTRYTRY RTRYTRYEAD ETRYVERY FTRYOURTH TRYLTRYETTER STRYTTRYTRYARTRYTINTRYGTRY TRYTRYFTRYROTRYTRYM TTRYHETRY TRYFTRYTRYOUTRYRTHTRY.
But you could fix that — dropping each instance of “TRY” led to the much more readable message:
USE THE FORCE EQUATION; THEN READ EVERY FOURTH LETTER STARTING FROM THE FOURTH.
These four instructions could then be successively applied to the main ciphertext. Applying the first three in exactly the same way as before yielded this very long string of letters (which we couldn’t fit on the page without the help of a few hyphens):
But what to do from there? If you just read every fourth letter, you got gobbledygook. First, you had to “use the force equation” from physics, which is “F = MA.” The text was full of “MA”s; replacing each one with “F” led to a slightly shorter string:
Reading every fourth letter there spelled out the weak point: “EXHAUST ACCESS SHAFT ALPHA.” While the Empire has apparently finally learned you have to cover the exhaust port, they forgot about the access shaft! (“ALPHA” was a bit of wordplay on the fact that this was a letter/decryption puzzle, and fit with the confirmatory clue that you were looking for the “Death Star’s Achilles’s heel.”)
SOPLRNYE [[3-LEVEL CODENAME ENCRYPTION USED]].
It was natural to guess that this somehow encoded Zigzag’s name — but how?
The phrase “CODENAME ENCRYPTION” was suggestive, but “SOPLRNYE” didn’t have the same number of letters as “Zigzag” (and besides, if we already knew the codename, what would be the use of encrypting it?).
But it wasn’t that we had encrypted the codename; rather, the codename itself described the encryption scheme. A few solvers recalled or discovered the existence of a “Zigzag Cipher,” in which words are written in rows or “levels” in a zigzag pattern. Using the appropriate decryption method with three levels gave:
Reading starting from the top left spelled out Zigzag’s identity: “SPYLO REN,” which of course was a pun on the name “Kylo Ren.”
And believe it or not, there was one more Easter egg hidden in this Conundrum: if you read every second letter in the decrypted ciphertext rather than every fourth, you would find the message “MIKE IS EVEN COOLER THAN GMT,” a shout-out to my editor, who is indeed even cooler than Grand Moff Tarkin (who is definitely the coolest character in all of Star Wars).
Zoz* solved first, for the fifth week in the row; up next were Noam D. Elkies, Lazar Ilic, Adam Slomoi, Matthew Stein, Franklyn Wang & Cindy Yang, Zarin Pathan*, Ruth Hofrichter & Matthew Smith*, and Michael Thaler. The other 16 solvers were Hernando Cortina*, Elizabeth Grove, Luke Harney*, Namitha Jagadeesh, Maya Kaczorowski*, Rachel Kaufman, Paul Kominers, Michael Perusse, Fernando Raffan-Montoya, Ross Rheingans-Yoo, Maggie Schreiter*, Spaceman Spiff, Sanandan Swaminathan*, Nathaniel Ver Steeg, Michaela Wilson, and Rostyslav Zatserkovnyi. (Asterisks indicate solvers who also figured out Zigzag’s identity.) Schreiter pointed out that Zigzag’s name also anagrams to “LONER SPY”; Zatserkovnyi reminded us of this third Death Star. To our knowledge, Wang & Yang were the only ones who noticed the Grand Moff Tarkin Easter egg. And thanks especially to Adam Rosenfield* for test-solving!
The Bonus Round
Grazing goat math. Star Wars droids, ranked by functionality and then getting stuck on the beach. Also: feathers in a fossil; and X-wings on display (hat tip: Ellen Dickstein Kominers). Briefly taking over the Google domain name; the math behind the game “Dobble”; failing at football; and a teeny tiny fire truck. Plus inquiring minds want to know: When are chess games most interesting on average?
You should pull these letters from the answer word itself, not the phrase you can make with the word!
Did we intentionally choose letters corresponding to two of the most classic rebel fighters – the X-wing and Y-wing? Of course we did!
That sound you hear off in the distance is a Sith Lord facepalming.
Not to be confused with this Agent Zigzag.
