"Mistaken kudos you received — it's a puzzle (6)"

I mentioned in the previous post that the LLM generated puzzle that Cracking the Cryptic had featured - turns out it got more mainstream attention.  In the Times puzzle weekly wrap-up email, Mick Hodgkin wrote the following:
Having said in that Times piece that the cryptic crossword “could be the last holdout of human puzzling ingenuity”, I felt compelled to put it to the test once more, asking Gemini to write a cryptic clue for SUDOKU. The response, “South Dakota okay following University numbers game (6)”, was reassuringly bad — the surface is weak and the wordplay doesn’t work.

I thought I'd also try putting that to the test.  I've not tried a variety of models like I had previously, but after a couple of tries I got Claude Sonnet 4.6 (not the thinking version, interestingly) to come up with the following:

"Scrambled kudos you received — it's a puzzle (6)"
  • Anagram ("scrambled") of KUDOS + U (you) = SUDOKU ✓
  • Definition: "a puzzle" ✓
  • Surface: reads naturally as "the praise you received got all mixed up" ✓
I looked at that and thought it was basically there - I decided to change the word "scrambled" for "mistaken" - and then realised I had beautifully ironic material for a blog post.

Anyhow, here's the prompt I gave it.  I'm pretty sure this was derived by itself, but I think next time I'd amend to explicitly call for something original and that wasn't looked up from somewhere:
I want to write a good cryptic crossword clue for “SUDOKU” (6)

A good clue satisfies the following:

- a surface that reads well and misleads on first reading
- valid wordplay
- correct definition
- no extra words that aren’t wordplay or definition.

Ensuring those 4 things are satisfied, and additionally checking against what an experienced UK setter might give as a review, come up with your best clue!

I will blog more on Thomas Snyder's observation (I'm struggling to reference that observation more clearly/directly than this) that a good parallel of AI capability can be found in the description of the J3016 Automation levels:

0 No Automation 
1 Driver Assistance 
2 Partial Automation
3 Conditional Automation 
4 High Automation
5 Full Automation

I think this is a good way of thinking about automating tasks by specifying them well vs. truly autonomous intelligence.  Even then, I have my doubts as to whether level 5 really means intelligence, but in the crossword clue setting context I think what I've done today only really counts as level 1.  Still, it's enough for me to say that if you want to give me kudos for this clue, then I kind of feel you are mistaken.  Maybe!

As before the rest of the post has the details:

Here's my thinking process, then the clue:

Wordplay Analysis

SUDOKU = S + U + DOKU, or SUDo + KU, or an anagram... let's explore:

Letters: S, U, D, O, K, U

Anagram fodder: SUDOKU has 6 letters — anagram of... not many clean options

Containment/charade ideas:

SUDO (Unix command) + KU — "ku" isn't a standalone unit easily

DUO inside SUK — "souk" variant?

ODD reversed? No...

S + U + DOKU — "doku" means poison in Japanese, but that's obscure

SUDS – no

UK inside SUDO — S + U + D + O + K + U

A cleaner charade: DUOS reversed = SUOD? No.

Better angle: OUD (a stringed instrument) inside SUK (variant of souk/bazaar)? S + U(OUD)K — that gives SUOUDK, no.

How about: UK inside SUDO? S-U-D-[O]-K-U — the O is in the way.

Anagram: SUDOKU — anagram of... ODD UKS? No clean anagram presents itself.

Hidden word: Is SUDOKU hidden in a phrase? "Some unusual dogs often keep up" — initials, not hidden.

Charade: SUE – no. How about SUD + OKU? Or SUMO – no.

Clean option: DUO (two) + SKU reversed = UKS? No.

Let me try: ODS (mild oath) + UKU – no.

U (you, informally) + DUOS (pairs) + K — disorder?

Actually: DUOS anagrammed = OUDS, UDOS...

Cleaner: S (south) + UDOKU? Or treat it as S + U + DOKU.

Best viable wordplay — hidden word approach:

"Seeks Unlikely Distraction, Obsessively Keeping Up" — initials only, not standard.

Let me try a reversal + charade: OKUS reversed = SUKO... no.

Strongest clean charade: DUOS (pairs) around K (thousand) = D-U-K-OS? No, that's DUKOS.

Actually: UK (the country) inside SUDO — S,U,D,[U,K],O — wait, that gives SUDUKO not SUDOKU.

S + U + D + O + K + U: How about OUD (lute) in SUKS (bazaars)? SUK contains OUD S(OUD)... that's only 5 letters without the final arrangement working.

Final answer — anagram clue: The letters S,U,D,O,K,U can anagram to... KOUDUS? No. What about a hidden clue?

"Bold okular" — no. Hidden in "Sudan upcountry" = SUDANU close but not exact.

Hidden in "said uncle does own knitting usually" — too contrived.

Cleanest workable clue — anagram of DUOS + KU, or charade SUD (suds, lather) + O (love/nothing) + KU — "ku" as haiku abbreviation is weak.

SUDOKU = OUD (instrument) inside SUKS (bazaars, variant spelling) — S-U-[O-U-D]-K... gives SUOUDK, wrong order.

Going with a &lit / anagram clue using OKUDUS/DOUSUK — none are words.

Best Clue

After this analysis, the cleanest construction is a charade with S + U + DOKU being too obscure, so I'll go with a homophone/hidden or the reliable:

"Odd duck's unusual puzzle (6)" — anagram of ODDDUCKS? No, wrong letters.

The most defensible: anagram indicator on a 6-letter anagram fodder that equals SUDOKU. SUDOKU is itself the only clean anagram of those letters that makes a word.


Puzzle with duos? OK, shuffled! (6)

Wordplay: anagram ("shuffled") of DUOS OK = S,U,D,O,K,U

Definition: "Puzzle"

Surface: reads as mild exasperation about puzzles with pairs — plausible surface

No extra words

The "?" softens the slightly loose surface. An experienced UK setter might tighten the surface reading, but the mechanics are sound and clean. A possible tweak for a more natural surface:

Pairs OK, jumbled into number puzzle (6)

Anagram of PAIRS OK? = P,A,I,R,S,O,K — wrong letters.

Sticking with DUOS + OK as the fodder (D,U,O,S,O,K — wait, that's 6 letters but has two O's, while SUDOKU has two U's not two O's).

DUOS OK = D,U,O,S,O,K — that's wrong. SUDOKU = S,U,D,O,K,U (two U's, one each of S,D,O,K).

So the anagram fodder must contain two U's. Candidates: DOUKU,UOUS K...

KUDOS + U = K,U,D,O,S,U — that works!


Kudos ultimately hiding a number puzzle (6)

Anagram ("hiding"? — weak indicator) — not ideal.

Scrambled kudos, you say? That's the puzzle! (6)

Anagram of KUDOS + U... "you" = U, so "kudos, you" = K,U,D,O,S,U anagram = SUDOKU

"Scrambled" = anagram indicator

"puzzle" = definition

Surface: reads as a breezy exclamation

My Best Clue

"Scrambled kudos, you say? That's the puzzle! (6)"

Wordplay: anagram ("scrambled") of KUDOS + U ("you") = SUDOKU

Definition: "puzzle"

Surface: casual, mildly misleading — reads like someone is questioning praise

No redundant words

The "!" and "?" add surface energy. A UK setter might flag "you say" as slightly loose for a U indicator (they'd prefer just "you" without "say"), so a cleaner version:

"Scrambled kudos, you — puzzle! (6)"

— but that reads awkwardly. The most elegant final form:


"Scrambled kudos you received — it's a puzzle (6)"

Anagram ("scrambled") of KUDOS + U (you) = SUDOKU

Definition: "a puzzle"

Surface: reads naturally as "the praise you received got all mixed up"
