A Clued Sudoku Puzzle? It’s More Than Meets the Eye


The hunt is always on for the next big puzzle idea.

Sometimes, it’s an old idea that gets repackaged and catches fire. That’s what happened with Sudoku, a puzzle that had been around since the late ’70s, but only rose to prominence decades later.

Other times, it’s a combination of different puzzle types that yields something special. Our friends at Penny Dell Puzzles, for instance, have a popular puzzle called Anagram Magic Square, which combines crossword-style cluing, anagrams, and the mathematical element of a magic square to create an engaging puzzle experience you can solve from several angles.

Whether a puzzle is destined for superstardom or not depends on a lot of factors: difficulty, the type of solving it involves, how intuitive the solving is (i.e. needing a lengthy explanation vs. getting the gist of the puzzle from a glance), visual aesthetics, and more.

As a puzzler, it’s always exciting to try out a new puzzle. Wholly original ideas are rare, to be sure, but even a single twist on an old classic can be enjoyable if executed well.

Today, we’re taking a look at a puzzle that combines Sudoku with cryptic crosswords (aka British-style crosswords). It’s called Cluedoku, and it was created by cryptic constructor Charlie Methven, better known in solving circles as Chameleon, a contributor to British puzzle outlets like The Guardian.


[Just a sample of the puzzle. Check out the entire puzzle here.]

Like Sudoku, Cluedoku involves placing the digits 1 through 9 into each row, column, and 3×3 square in the grid. But unlike Sudoku, there are no set letters.

Instead, you have 81 clues, one for every cell in the grid, utilizing cryptic-style cluing to hint toward which of the nine numbers goes in a given cell.

Once you’ve unraveled a clue and placed a number in the grid, standard Sudoku rules apply: that number will only appear once in a row, column, or 3×3 square.

But that’s easier said than done. These clues run the gamut of slyly clever to almost baffling. Even when you consider that there are only nine possible answers for each clue, it’s still a challenge. (Plus, not all of the clues adhere to the standard cryptic cluing mechanic of having both a definition AND a wordplay clue included.)

That being said, you’ll find lots of traditional cryptic cluing tricks at play here.

Now, we’re going to be discussing specific clues and answers from this puzzle, so this is your spoiler warning.








Last chance to solve without spoilers!







Okay, here we go.

In terms of traditional cryptic cluing gimmickry, we see hidden words, anagrams, homophones, word reversals, and more.

In clue 6 — Axis revolves without beginning to accelerate — we revolve (aka reverse) axis to spell SIXA, and then drop the A (“without beginning to accelerate”) to spell SIX.

In clue 8 — Prime cut from sloth reeks — the answer hides in plain sight, as a prime number (three) reads out in sloTH REEks (and can be cut out of it).

In clue 22 — Scenes in X-Men Origins reveal how many claws Wolverine has! — the phrase “origins reveal” points towards the first letters of the words that precede it proving the answer, meaning that SIX is the number of claws Wolverine has (three on each hand).

There is a similar game in clue 67 — With only seconds remaining, Officer Columbo outwits crook — which has the second digits of “Officer Columbo outwits crook” spelling out FOUR.

In clue 27 — UFO demolished third of Parliament Square — the letter R (“third of Parliament”) gets mixed up with UFO to make FOUR, a square.


But other clues would be familiar to crossword solvers in America.

Clue 29 — Number of Romans in the New Testament? — is simple wordplay for 6, since Romans is the SIXth book. (Similarly, clue 62 — Number of lines taken by bar staff — is a reference to the FIVE lines that make up a staff in sheet music.)

Clue 34 — Top score in Scrabble — is a bit more devious, requiring you to know that T is worth 1 point, O is worth 1 point, and P is worth 3 points, making the correct answer FIVE.

Clue 48 — Man’s arms’ legs’ digit — feels like a clue you’d see at the Indie 500 or Lollapuzzoola, because it’s initially baffling, but then reveals itself as merely clever and challenging. You see, there are THREE legs on the coat of arms for the Isle of Man. But that’s concealed by the wordplay involving three different words that don’t mean what you’d think.

This mix of American and British-style clues made for a fun solve that mixed and mingled two worlds of cluing nicely.

I think my favorite clue was Clue 39 — 192+284 — because it was built like one of those magazine word puzzles, the ones where “rockcaughthardplace” means “caught between a rock and a hard place.” In this case, you have “2+2” literally in 1984. And for anyone familiar with George Orwell’s famous novel, 2+2 in 1984 equalled FIVE.

Although obviously Cluedoku isn’t really sustainable as a recurring puzzle — you’d burn out your anagrams and homophones pretty quickly, as Chameleon himself stated in an interview — it is an impressive marriage of two different puzzles that rarely interact otherwise.

But he did raise the possibility of another variation in the future:

If I did another Chameleon cluedoku, I think I’d use the seven colours of the rainbow plus black and white, as solvers could then colour in each square as they solved. How’s “Cry over Norwich’s core Canary”?

That sounds like a fun follow-up to an interesting puzzle.

Get thee to a punnery!

Wordplay is an integral part of many puzzles, from anagrams and rhymes to letter-shifting and palindromes. But perhaps the most predominant form of wordplay is the pun. (Where would Wordplay Wednesday be without them?)

Sometimes puns are Cryptogram answers or Anagram Magic Squares solutions. Sometimes they’re fiendish crossword puzzle clues that send you one way when your answer lies elsewhere, or they’re the key to figuring out the theme entries in a Thursday New York Times puzzle.

Whether it’s a groaner or one that makes you laugh out loud, a pun can add humor and style to a puzzle.

Some of my fellow puzzlers have some classics to their credit, like Penny Press editor Keith Yarbrough’s “Public hanging” for ART, or crossword guru Eileen Saunders’ “Wombmates?” for TWINS.

But it’s not just in puzzles. Social media has given the art of punnery a new lease of life. Several YouTubers have made puns their stock in trade, like My Drunk Kitchen’s Hannah Hart and You Deserve a Drink’s Mamrie Hart. (No relation.)

Check out this video by musician and pun enthusiast Andrew Huang:

Twitter is also home to some monstrously talented punsmiths. Here are two recent favorites I stumbled across:

And did you know there are even contests and prizes for great puns?

Every May, the O. Henry Pun-Off attracts wordplay aficionados from all over to ply their trade in front of a live audience!

For a primo example, here’s a video of champion Jerzy Gwiazdowski busting out a flurry of geography puns:

PuzzleNation wordplay = Now radiant puzzle ploy

[Alternate anagrams include “Puzzle patron, now daily” and “Plow into any rad puzzle.”]

Anagrams are a cornerstone of modern pen-and-paper puzzling.

They make frequent appearances in cryptic (or British-style) crossword clues, and many puzzles and puzzle games — from Anagram Magic Square and Text Twist to Secret Word and Bananagrams — rely heavily on anagrams as an integral part of the solve.

I’ve written about them several times in the past, but for the uninitiated, an anagram is a reordering of the letters in a word to form a new word or phrase. PEALS anagrams into LEAPS, PALES, LAPSE, SEPAL, and PLEAS.

As the old joke goes, “stifle” is an anagram of itself.

But the best anagrams rearrange the letters in a word into something related to that word. Fans of The Simpsons may recall that Alec Guinness anagrams into “genuine class.”

There are numerous examples of great anagrams all over the Internet. Here are a few classics:

  • The eyes = they see
  • Clint Eastwood = Old West action
  • Eleven plus two = Twelve plus one
  • Dormitory = Dirty room
  • A decimal point = I’m a dot in place
  • A gentleman = Elegant man

One of the best online anagram programs out there is hosted by wordsmith.org, and at the top of their page, they remind us that “internet anagram server” anagrams into “I, rearrangement servant.”

You can find some unexpected surprises when you play with anagrams. Did you know that William Shakespeare anagrams into both “I am a weakish speller” and “I’ll make a wise phrase”?

There are entire forums online dedicated to terrific anagrams, some fiendishly clever, others impressively insightful. (Of course, sometimes crafty punctuation makes all the difference.)

Madame Curie becomes “Me? Radium Ace.”

Monty Python’s Flying Circus becomes “Strongly psychotic, I’m funny.”

The possibilities seem endless when you delve into longer phrases. I’m going to close out this tribute to anagrams with two of the most amazing ones I’ve encountered during my time as a puzzler.

The first involves the iconic line as humanity took its first steps onto the surface of the Moon:

Neil Armstrong: That’s one small step for (a) man, one giant leap for mankind

anagrams into…

Thin man ran; makes (a) large stride, left planet, pins flag on moon! On to Mars!

[I’ve included both what Neil said and what was broadcast back to Earth. Hence, the A in parentheses in both versions.]

The second takes one of Shakespeare’s best known lines and offers some engagingly meta commentary on the play itself:

To be or not to be, that is the question, whether tis nobler in the mind to suffer the slings and arrows of outrageous fortune…

anagrams into…

In one of the Bard’s best-thought-of-tragedies, our insistent hero, Hamlet, queries on two fronts about how life turns rotten.

So whether you’re playing Scrabble or tackling David L. Hoyt‘s Jumble, anagramming is a worthwhile tool that belongs in every puzzler’s skillset.

Do you have any favorite anagrams, fellow puzzlers and PuzzleNationers? Let me know! I’d love to see them!

These puzzles deliver!

Puzzles are all around us. They’re in our newspapers and on our phones, they’re lurking in math problems and board games and children’s toys.

But as it turns out, according to an article forwarded to me by puzzler and friend of the blog Cathy Quinn, they’re also on our stamps.

At least in Macau, that is.

Late last year, Macau Post released the latest stamps in their Science and Technology series. Previous editions have featured the Golden Ratio, Fractals, and Cosmology, but this time around, they selected a topic near and dear to the hearts of many puzzlers:

Magic squares.

For the uninitiated, a magic square is a grid where the numbers within add up to the same total in every row, column, and diagonal.

Our friends at Penny/Dell Puzzles utilize patterns like this in their Anagram Magic Square puzzle, where a word to anagram accompanies each number in the diagram, eventually spelling out a bonus phrase or quotation.

But at its core, a magic square is about cleverly balancing every element until you reach a harmonious arrangement. It’s a curiously meditative sort of puzzle solving, and I can see how it would appeal to the meticulous nature of stamp collectors worldwide.

Here are the six stamps currently available through Macau Post.

There’s a classic 4×4 magic square grid in the upper left and an ancient Latin palindrome in the upper right, as well as part of a 4th-century Chinese palindromic poem in the lower left and a geometric puzzle in the lower right where the pieces in the inner squares can make all of the designs in the outer squares.

Not only that, but three additional stamps will be released this year, making a total of nine themed stamps, and wouldn’t you know it? The stamps themselves can be arranged to form a magic square when assembled, based on the values printed in the corner of each stamp.

Just another sign that puzzle magic is alive and thriving all across the world.
