Not Colorado 2 — Odd Corner

(Published on 6. June 2026, 19:21 by andredenofrio)

Solve on SudokuPad

Rules:

  • Normal Sudoku rules apply.
  • Cells separated by an X sum to 10.
  • Cells separated by a V sum to 5.
  • All possible Xs and Vs are given. Therefore, if two orthogonally adjacent cells are not separated by an X or a V, they do not sum to 5 or 10.
  • The Little Killer clue outside the grid gives the sum of the digits along the indicated diagonal.
  • A grey circle marks an odd digit.

This is the second puzzle in my Not Colorado series, made as a tribute to Florian Wortmann's wonderful Colorado series. It was created with AI assistance, with the intention of recreating some of the beautiful colouring and disambiguation moments that made the original series so memorable.

Estimated difficulty: 2/5.

Solution code: Row 1 followed by column 1.

the puzzle is nice..
but a two part solution code for a puzzle that's actually in the lower realm of 1* difficulty is a bit excessive.

yes yes copy-tool, I know but you cannot copy a cell twice so you have to go back and forth, which is silly.

and another thing:
demanding that setters not use ai in 2026 is like demanding that we not use photocopiers or pens, or paper. maybe we should go back to stone tablets?
ai is a TOOL. it depends on HOW you use it. here, anyone who bothers to look can clearly see the "hand-crafted" elements.

as this variant goes, it is very easy.
but the variant itself starts at level 2.
that's because you need to know the required procedures quite well to have a comfortable solve.

as for the quality rating, recognize that there are lots of people on this site who will downvote a puzzle just because they got a couple red lights while driving their hummers

Nice puzzle. But it seems people prefere "handmade" ones. For the 18 digit code: You all know that there is a copy tool you can enable on sudokupad? With that I could highlight row 1 and col 1, copy-paste it and only inserted the top left cell again in the middle, since the cells are copied in row major order. Still, a single row or col is enough for the solution code IMHO.

18 digit solution code why

You seem to be still in 18th century as far as code is concerned.

Martina, das wusste ich nicht. Aber Du hast völlig Recht, nur Bewertungen gehen ohne Code nicht. Danke schön für Deinen Kommentar, habe was gelernt!

@Onkel_Dagobert Ich gebe nie die Lösungscodes ein und kann trotzdem Kommentare schreiben.

Ich persönlich habe kein Problem mit KI-Puzzles, und ich finde es besonders gut, dass Du die KI-Beteiligung angegeben hast. Und was daran „moralisch falsch“ sein soll, verstehe ich schon mal gar nicht. Mir hat das Lösen Spaß gemacht, und darum geht es doch wohl. Allerdings: Schwierigkeit für mich nur *, Lösungszeit 13 Minuten mit Unterbrechung. Was ich wirklich unnötig finde, ist ein 18-stelliger Lösungscode. Hätte ich nicht diesen Kommentar schreiben wollen, hätte ich mir nicht die Mühe gemacht, den einzugeben. Schon 9 Stellen finde ich eigentlich übertrieben, aber 18….

it is always ok to SKORP ai-generated puzzles
it's always morally correct
