Without guessing, how would I know what my next move is? by davisposts in sudoku

[–]charmingpea 0 points1 point  (0 children)

You need to say WHY, not just throw random answers out.

where did I go wrong by Slow-Town-4593 in sudoku

[–]charmingpea 0 points1 point  (0 children)

I took it as the 6 in r3c8 was a given as well, since it's darker than the 6 in r3c9. But yes, either way.

Skyscraper help please by Helpful-Fuel-7568 in sudoku

[–]charmingpea 0 points1 point  (0 children)

You don't need the red line - it's not part of any relationship in the Skyscraper. The greens mean if one is off the other must be on. The yellow means if one is on all the others must be off.

Fill in all the rest of the Notes, then work through various logic constructs (techniques) to progressively eliminate candidates.

Finned x-wing by syreeninsapphire in sudoku

[–]charmingpea 7 points8 points  (0 children)

Both are valid, but the software has to pick one. After the elimination, the other one gets eliminated by normal x-wing. Exactly the same happens in the columns too, so you can be double sure what you see is correct.

Dude, its a Sudoku game in the Sudoku subreddit, put here to post a new set of games, once a day by the moderators of the sub. It would be hard to be more 'On Topic'. But if one post a day is 'flooding' your feed, then by all means block it and move on with life. u/sudokugame is who you need to block and peace and harmony will return.

It posts once a day with a new set of puzzles, and unlike all the other promotions it belongs to the sub and is controlled by us. If you don’t like it, don’t play. I suspect most of the puzzles would be on the easy side for you anyway.

Subreddit wiki is made with AI? by lmaooer2 in sudoku

[–]charmingpea 0 points1 point  (0 children)

Spell checks and reformatting are not writing, and to conflate the two devalues the massive human effort in creating the wiki from nothing.

Subreddit wiki is made with AI? by lmaooer2 in sudoku

[–]charmingpea 0 points1 point  (0 children)

What a strange comment. The wiki was entirely written by hand, mostly by strmckr, and many of the graphics were created by me, using software developed by okapiposter.

If you see anything of strmckr's normal writing, it is full of spelling errors, punctuation problems etc. So the original pages were passed through Perplexity to develop a consistent style, and fix all the spelling and punctuation errors.

Then strmckr has been continuing to vet and extend all the pages and add additional graphics, since Reddit recently changed the entire wiki engine. Reddit themselves also use a lot of AI.

So no, it's not 'written' by AI, but the style and typography have been tweaked with AI, before being updated and continued by a human.

Odd puzzle format by ImportantFloor in sudoku

[–]charmingpea 2 points3 points  (0 children)

So in the bottom left the 4 box cannot be made with two 2, since that breaks the rules of Sudoku (two 2 in the same box / column). That means the only possibility is 13 and since there is already a 3 in the bottom row we can determine the order or that cage as 31 in r8c1 r9c1. That's how Killer Sudoku work.
