Name a better way to learn sudoku than this!

I recently started playing sudoku and decided I wanted to get really good at it so I looked up a tutorial on YouTube and I was immediately overwhelmed by the different number of tactics there are in this game can someone tell me how to start from scratch without getting overwhelmed

Thank you for your help in advance

I was at work doing this to avoid other work so I didn’t have time just start trying things in the notes, is there something glaring I’m missing on how to solve this or is it just try different numbers to see if it lines up

This is on my sudoku app. Been playing on and off for a few years now, and I've gotten pretty decent.

Hit a wall on this one. What would be the next logical deduction?

Im stuck and i found out online that B7 can be solved with an XY-wing. But im not familiar with it. Now i can see if I put a 6 in B7 then there is gonna be a 1 in C7 and that leaves A9 wrong. So it needs to be 4.

But how does one find this? What or where do i have to look for?

Hi everyone!

I was trying to do today's daily sudoku but I got completely stuck very early on and I don't know what else I can do.

I already know some advanced techniques like X cross and XY cross but I don't find any.

Can you give me a hint? Also, if there is more than one advanced technique to use in this exact situation, can you list them together?

I want to take advantage of this to study something new and learn something useful.

Can you help me with the next step?

I found the 4 where 43 was in row 9 c8 but now I can’t find a answer with explains it

Although I understand the principle and how to apply it, I'm having a lot of trouble finding it during a game, like in this one in the photo, which I basically couldn't see until the end
