The Peculiar, Particular Art of Palindromic Puzzling!

Palindrome, written as an ambigram.

I’m a sucker for wordplay. I’m sure that comes as no surprise to you, gentle reader. You’re probably a fan of wordplay as well.

Two of my favorite forms of wordplay are the palindrome and the semordnilap.

For the uninitiated, palindromes are words, phrases, or sentences that can be read the same both backwards and forwards. KAYAK, RACECAR, etc.

A semordnilap (literally “palindromes” backwards) is a word or phrase that reads as one thing forwards and another thing backwards. STRESSED and DESSERTS, for instance.

It will come as no surprise to anyone who solved my Thisaway or Thataway crossword I shared a few weeks ago that I’ve had palindromes and semordnilaps on the brain.

My goal was to make every across entry above the center a palindrome (except for the entry PALINDROMES) and every across entry below the center a semordnilap (except for the entry SEMORDNILAP).

After trying several different layout and ideas, I finally got the puzzle to a place where I was happy with it. And now that it’s been shared with solvers, I’ve been wondering if anyone else had tackled the combination of palindromes / semordnilaps, and crosswords.

Thankfully, Xwordinfo made the searching for them easy.

I found this Joe Krozel puzzle from December 23rd, 2008, where the entire puzzle can be rotated 180 degrees and read out the same.

It’s an entire puzzle of semordnilaps!

Alex Eaton-Salners executed a similar idea on April 9th, 2019, creating a puzzle where every across entry is a semordnilap, cluing both the word reading forwards and the word reading backwards.

Leo Tsai managed the same trick as Krozel in a Puzzmo mini on May 20th of this year, offering two mini grids that reflect each other. (Solving this puzzle while constructing one in a similar vane was encouraging!)

On June 6th, 2023, Daniel Jaret’s crossword appeared in the New York Times, and executed the same trick managed by Joe Krozel 15 years earlier! Once again, the entire puzzle could be rotated 180 degrees.

He also managed to place two palindromes at the very center of the puzzle, RACECAR crossing STETS, which is a terrific extra touch.

That’s more puzzles than I expected when I started hunting for palindromic crosswords!


Of course, crosswords aren’t the only puzzles where you can see palindromes and semordnilaps.

Our friends at Penny/Dell Puzzles have several puzzles where words overlap and read backwards and forwards. Right of Way and Crozzle both come to mind.

But the best example in their puzzly library is undoubtedly Bull’s-Eye Spiral.

Bull’s-Eye Spiral challenges solvers to use the clues provided to create a chain of answer words that can be read both forwards and backwards.

Unlike a single semordnilap like STOP and POTS where one word can be reversed into a different word, the answers in Bull’s-Eye Spiral overlap, allowing the backwards words to bleed into the forwards words, creating a massive spiraling chain of words that’s actually two chains of words where the only common breaks are at the beginning and the end.

I’ve never tried to construct a Bull’s-Eye Spiral, though it does seem like a fun challenge to put on my ever-growing to-do / wish list.

I did, however, manage to construct a Framework puzzle years ago with only palindromes as answer words.

It was challenging to construct, not because of the limited wordlist, but because all the common letter crossings made it difficult to ensure there was only one way to complete the grid. (No alternate solutions here!)

Happy solving!


Musician, parodist, and wordsmith “Weird Al” Yankovic once said that “the writing of a brilliant palindrome is a small miracle, and that, I think, deserves to be honored more than a lot of the stupid and inconsequential things we often celebrate in our culture.”

Do you agree with him? Are you a fan of palindromes and semordnilaps, in puzzles or otherwise? Let us know in the comments section below! We’d love to hear from you.

It’s Follow-Up Friday: Word Ladders edition!

original-206610-1

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’m posting the answers to last Thursday’s Word Ladder puzzles!


First off, there are the two Word Ladders from Lewis Carroll’s puzzle collection Doublets:

Cain to Abel: CAIN-CHIN-SHIN-SPIN-SPUN-SPUD-SPED-APED-ABED-ABEL

Tears to Smile: TEARS-SEARS-STARS-STARE-STALE-STILE-SMILE

lewis_carroll_quote

And here are the solutions to crossword constructor Joe Krozel’s bonus Word Ladders from his New York Times crossword:

1. Table tennis: For ages, the only joy in my life.

PING-PONG-LONG-LONE-LOVE

2. Unspeaking inspirer will simply have to communicate in taunts.

MUTE-MUSE-MUST-JUST-JEST

3. Upon removing the strap, Mr. Rogers dashed away from his snow vehicle and glided.

FREE-FRED-FLED-SLED-SLID

4. Sell contraband to a flock of Jerry Garcia fans with intensity.

DEAL-DEAD-HEAD-HERD-HARD

5. Audacious poet (with signs of aging) outlaws military conflict.

BOLD-BALD-BARD-BARS-WARS (or BALD-BAWD-BARD-BARS-WARS, although the first answer changes every letter from the starting word)

How did you do, fellow puzzlers? Did you crack them all?

Scaling a Word Ladder to Success!

word-ladders-1

If I challenged you to transform the word ROCKS into the word SPARK, could you do it? By changing one letter at a time, making a new word every time, five changes would complete that chain of words.

ROCKS – SOCKS – SOAKS – SOARS – SPARS – SPARK

Congratulations, you’ve chipped away at those rocks, created a spark, and ignited a puzzly fire! Not only that, but you’ve just built yourself a Word Ladder.

Word Ladders, also known as Changawords, word-links, laddergrams, doublets, word golf, and numerous other names, have been around in their current form for nearly a hundred and forty years. Lewis Carroll is credited with creating them, publishing a series of them in Vanity Fair magazine and a collection of them under the name Doublets.

For example, in Doublets he challenged solvers to connect CAIN to ABEL. He did it in nine steps. Can you match him, or beat him?

Can you turn TEARS into a SMILE in six steps?

As you can see, there’s often a theme or connection linking the words. Some Word Ladders connect anagrams (like SEAT to SATE) or semordnilaps (like WOLF to FLOW). Others connect two words in a phrase (like TRUE to BLUE) or link two words in the same category (like LION to LAMB if the theme were “Mammals”).

They can vary in word length as well as in number of steps between words. Often (but not always), the fewer steps, the easier the solve.

But, as it turns out, solvers continue to add new variations and wrinkles to the established format.

Sunday’s New York Times crossword puzzle featured Word Ladders as themed answers, but these Word Ladders actually formed coherent sentences! 92 Across, for instance, was clued “Boisterous oaf confused the previous set of actors.” And you’d have to be a pretty savvy solver to come up with LOUD-LOUT-LOST-LAST-CAST as the word ladder that fits the clue!

And the constructor, Joe Krozel, kindly offered a few bonus Word Ladders for solvers to unravel. Can you crack them all?

1. Table tennis: For ages, the only joy in my life.

2. Unspeaking inspirer will simply have to communicate in taunts.

3. Upon removing the strap, Mr. Rogers dashed away from his snow vehicle and glided.

4. Sell contraband to a flock of Jerry Garcia fans with intensity.

5. Audacious poet (with signs of aging) outlaws military conflict.

How many successful Word Ladders can you build? Let me know! I’d love to hear from you!
