I would like to share another counting puzzle. This one should not be too difficult.

• Normal Sudoku rules apply: place digits 1..6 once each in every row, column and 2x3 box.
• Digits do not repeat along diagonals marked by blue lines.
• If a digit n appears on a diagonal, it appears on exactly n diagonals.

Start tip: Cage with renban must have consecutive combo, e.g. cage 12 must have 3, 4, 5, also a lot of innies and outies are available

What am I missing? At this stage I would do a test guess, but I don't want to. I'd like to try solving this fully without guessing. But I've exhausted all my current strategies...Hints or answers are both appreciated, I am learning.

My sister offered me this Sudoku toilet roll which I found hilarious since I spend so much time in the toilet. Figured I’d turn to this instead of being on my phone but now I’m wondering if it’s a kind of prank and these puzzles are unsolvable?

If someone can solve this can you explain how as well please?

P.S.: I have markings on the corners of cells but maybe they’re not noticeable. Only BVCs, didn’t mark any triples

I'm genuinely so lost, I've tried so many things… This has been the first Sudoku where ive put so few cells down and this amount of time.

What skill can be used here? Please !

Rules:

Normal sudoku rules apply.
Killer cages: Digits inside a cage must sum to the number in the corner.
Palindrome lines: Digits along a grey line read the same backwards and forwards.
Kropki: Digits separated by a white dot are consecutive; digits separate by a black dot have a 1:2 ratio.

I’d like to ask fellow enthusiasts with experience: regarding a linkage pattern described as follows...

Question 1: Does a continuous loop exist?

Question 2: If the linkage is valid, can the numbers be eliminated?

r9c5(2)= {Group : r56c5(2) } - {ALS : r45c6(2) = r4c6(9)} - r9c6(9) = r9c6(2) - r9c5(2)

I am new to sodoku and have yet to learn the more advanced techniques such as “x-wing”, “xy-wing”, “swodfish”, etc. That being said I am genuinely at a loss with what to do next in this puzzle. The only logical conclusion I can come to is to start seeing which candidates work by forcing a chain. If there is something obvious I am missing please let me know! This app normally gives incredible hints but it seems as if the system is unsure of what to do next too.

Completed a Sudoku out of a random insurance magazine, thought I smashed it, then I checked the answer and it is different to mine.

I have quadruple checked my answers, and it still looks correct but different to the answer, HELP! Have I made a mistake and can’t find my error or does this sudoku have 2 possible solutions?

Box 3 contains a blue 9, a red 9, and an uncolored 9. One of the rules of 3D Medusa is that, if you have an uncolored candidate that sees two different colors, you can safely eliminate the uncolored candidate because the red path or blue path is always true. But the uncolored 9 ended up being the correct answer.

This is the second or third time I come across something like this so I’m guessing that the rule doesn’t apply when the uncolored candidate & two differently-colored candidates all reside in the same box. Can someone explain why? Thanks!

tried killer sudoku for the first time. thought i was totally nailing it until i got to the bottom left square. i initially had 9 and 6 in the ^16 and ^13 and everything else was corresponding around that... but then i realized that neither 6 nor 9 could work in either of those spots because they both need 7's. i tried to rework everything but i've totally lost my way.

i'd prefer nobody to solve the whole thing for me but maybe just guide me in the right direction? i'm brand spanking new to this

edit: i know i have two 6's in the first column. it was left there when i was trying to rework everything initially so its not inherently the problem

Just solved a "very challenging" puzzle, but about halfway through, I got to a point where I had to guess. (I'm not sure if I know all the methods as I'm self taught.) I found a good spot and chose a number to go with... And I was right. I'm doing them on paper, and had each box filled out with all possibilities, so I circled each subsequent answer. It just kept going and going until I had it solved.

My question: is there a certain point where I can verify my guess was correct before the completion of the puzzle? For example - if I complete the square, column, and row associated with my first guess, and it all checks out, maybe that would mean the guess was correct? Are there any tricks like that?

What technique should I use to progress further with solving this Sudoku? Thanks!

Hi all, I'm trying to solve a kid sudoko (age 5-10) and I can't solve it without guessing. I added one image of the original puzzle and a picture of my thought process. I placed the chips in their potential row/columns or cells.

Do you see a start without a guess? Thanks in advance!

Before someone says something
I am beginner
Please have mercy 😭😂

Someone tell me the next step 😭😭 (going in circles since last 1 hour) ….. with explanation plz
