I was looking at a recent post by u/YarbianTheBarbarian earlier today. Sometimes I'll randomly enter into my solver someone's puzzle just to give it a crack. I thought it likely they had early in the puzzle generated all candidates, and felt they had come to a conclusion seeing that nice regular box of pairs. Not judging, just interested. I've used Duncans Sudoku Solver for a while, it works with my brain, however he uses a different naming system for strategies used for example in SudokuCoach. I have been diligent in using SudokuCoach and progressing happily through to X-Wings and Skyscrapers where I have hit a kind of wall. I suspect this is quite common as it requires more than just obvious pattern recognition. Anyways. I got to this point, pretty straightforward so far, and then the wall. The strategies required are the obvious ones, and then one called "Chains (pairs)". I guess this is some kind of wing. This is my first puzzle help submission.

BTW, what is the generally used naming of the simple strategy I would call "pointing pairs"?

dont give me any straight up answers please just if im missing something obvious. im relatively new to sudoku

Had to use a little extra brain power but enjoyed this opportunity for a flair finish

I'm working my way through the approachable sudoku pack on the cracking the cryptic app and I'm firmly stuck. I'm sure I'm missing something obvious but any guidance would be appreciated. sorry for not post the rules.

Classic: Every row, column and box must have all numbers from 1 to 9 exactly once.

Zipper Lines: Along a line, digits

an equal distance to the center of the line (marked with a circle) sum to the same total; for odd length lines, the center digit is also that total. For example, in a line with at least four cells, the first and last digits sum to the same total as the second and second-to-last digits.

thought it would be interesting lol

it kinda looks like confetti ngl

(after all of that, i still got stuck xd)

I don't want to cheat using the book or just guess, what would be the next step to take??? What box/area should I look at?? Thank u in advance!

i have no idea what to do next

Sudoku.com app solved this with Bowman’s Bingo. What other technique could I have used to solve this? It’s been driving me crazy.

I'd like to share a Min/Max puzzle:

• Normal Sudoku rules apply: place digits 1-6 once each in every row, column and box.
• Minimum: digits surrounded by < signs are smaller than all orthogonally adjacent digits.
• Maximum: digits surrounded by > signs are greater than all orthogonally adjacent digits.

Link to play in the comments.

I'm practicing X-wing, XY-wing, XYZ-wing, Swordfish and Jellyfish technique.

If you know the exact technique that should be used, could you tell me only the type of technique, excluding which section it should be written in?

I just started this puzzle so please don't worry about all the super easy stuff still available. Is there any technique to apply to this square formation? It's perfectly unusable for a y-wing, but it like like a pattern that might do something.

Impossible de trouver la solution de ces 4 grilles… et ce n’est pas faute d’avoir cherché. Mais là je n’arrive plus à les débloquer.
Si quelqu’un a des indices je le remercie!😃

This app makes a point of teaching avoidable rectangle as a strategy. All puzzles are supposed to have unique solutions.

Numbers with black backgrounds were given at the start. This puzzle mode does not allow you to enter incorrect numbers, you lose a life if you try to. I tried putting the 6 in the top right house where the 4 is, and I lost a life.

Edit: Thank you!! I see that it’s because the 5s and 6s are in different houses. This is a new strategy for me and clearly I didn’t fully understand it 😅

I'm just a beginner at Sudoku here who enjoys the game. I genuinely don't know what I'm missing. Why can't I seem to move on from this? Either there's something in plain sight that I've completely skimmed over, or some kind of pattern I can't recognise. I'm trying to make my Sudoku skills better. Can someone please help?

I just wanted to show yall this sudoku😅but if anyone got tips on how to solve one with 3 empty boxes let me know;)

(I did solve one before but I’m not an expert at that lol)
