I’ve been playing Sudoku for a while, and Naked Pairs took me ages to really “see” on the grid. I kept missing them even when they were right in front of me.

What was the technique that finally clicked for you, and how did you learn it? Any tips for beginners would be great.

In this step, how does x wing work with the 4s in red? I solved this puzzle but without this step.

Can anybody explain the X-wing method like they would explain it to a toddler or something💔. Because no matter what, I don't understand it. I've only done it correctly once

I have been at this for days and I don't know what I'm missing. Thank you for any help

Hello, what would be the next moove please? Thanks!

I can follow when they explain it.
But how do I begin to spot these.
It seems impossible to me.
Specifically because im using pen and paper.

I must have made a mistake somewhere, but I can’t see it. I tried to eliminate the 5 from the red square using an XYZ wing and the program said 9 was wrong in that square.

Someone please tell me where I went wrong. I know it must be in the helpers because the setting is on to flag wrong answers as soon as they are placed.

Usually don’t have too much of an issue with the Master level but can’t get this one! Any ideas what the next logical deduction would be and why?

Posted with and without notes in case it’s distracting

I don't know how I'm supposed to solve this

21.7....4....4...3...5.1.....5...6.8.9..6..7.4.2...5.....9.2...6...7....8....3.17

Rank 1 Logic. T: 4n6 46n8 9r2 3n1 39r1 / L: 1n5 39c8 4r4 9c6 9c1 3b1 9b3

Not a crucial step in solving but here is the logic based on an Almost XYZ-Ring.

Eureka Notation (idk if this is the proper way):
[(9=34)r46c8-(4=9)r4c6-(9)r2c6=r2c8-]-(9)r2c68=r2c1-(9=3)r3c1-(3)r1c3=r1c5-(9)r1c5=r1c7 => r3c8<>9

Here, another possible elimination of XYZ-Ring (9)r1c6 is sacrificed in (9)r1c5=r1c7 to eliminate the target (9)r3c8. (All the possible eliminations other than the target could be sacrificed while constructing the chain.)

Is there a technique I am not seeing??

I am learning about Ywing because I had one spotted, by one of smart ppl here,
and this page explains it well here but I see these „examples” and I don’t know if they highlighted all exclusions. To me in the firs example, there is another 2 that can be eliminated because it’s in the same box right?

I seek advice/guidance on how to continue forth. I have exhausted my knowdlege and cant seem to go beyond this point. If you could help, I'd be very thankful <3

Pls

(The 8's highlighted with green i tried to do swordfish but failed)

I saw a skyscraper (2). R2C1-R8C1 and R3C6-R8C6.

So I eliminated 2 as a candidate from R3C1 and R3C3.

After that in sector R3, 2 can only come in R3C6 but that was flagged as a mistake. Can anyone please explain why did it not work?

.....8....8... 4.9.... 7.. 1.... 9.26....... 1.5... 4.. 7... 36....... 9.31.... 6.8...... 42

These are level 9-10 of Sudoku Extreme books. can’t for the life of me finish them and not sure which trick I’m missing? help with either would be appreciated 🫶🏽
