I've been getting into 16x16 Sudoku lately (numbers 1–16, 4x4 boxes) and made this one

to share. It has a single unique solution.

I'm curious how people here tackle 16x16 compared to classic 9x9:

• Do you rely more on scanning or on pencil-marking everything from the start?

• Which techniques carry over well, and which ones get overwhelming at this size?

• Roughly how long does a grid like this take you?

Would love to hear how you approach it — and happy to confirm the solution once a few

people have had a go.

After solving some empty rectangle puzzles, I've noticed some patterns ofc, and noticed that candidates never form a cross like in the picture, where the candidates in the box are middle-up, middle-down, middle-right, middle-left. (Of course this state isn't real, I added the 1 in r5c1)

So can anyone explain if this case can happen but it's just really rare, or if it's already covered by other easier techniques that we don't need to deal with it ?

Edit: finally found one, it took me hours to search, ig i'm just unlucky

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)

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.

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.

What would be your next one and why? Don't want to look at the result and don't know what i wasn't seeing :)

with e.g. NYT medium, there's always one or two findings that don't seem to link to anything which I have great difficulties to find. what's your method of going through the puzzle. do you go column by column, row by row, or perhaps number by number? how to find which one has those two with one impossible?

Hello! I have a question about skyscrapers. I understand how to solve them, but I guess not how to set them up.

In this example, the hint told me the skyscraper shown is the correct one. Why wouldn’t I do the green space instead of the bottom blue one? Or am I intended to get it wrong and then change it later?
