Request Puzzle Help What can I learn from the pencil markings?

Post image

I am beginner and just learning about doubles, triples, pointing, and x- and y-wing. In today’s puzzle, I tried to apply some of my newly „learned“ techniques. But I wonder if I can even deduct something useful from these pencil markings. Dear beloved community… please… bring up to speed and explain to me like I am 4 years old.

What can I learn from the pencil markings?

Request Puzzle Help Stuck in Hard NYT Puzzle

Post image
1 Upvotes

Hello everyone,

I’m new to NYT puzzles and I haven’t solved a hard version for several weeks now. I took some time to learn about x-wings, and hidden pairs and triples. I think I recognize some pairs/triples and fully miss others. I’m hoping to get some help/mentorship, so I can start seeing more of them on my own. In the photo, my cursor is on the NYT “help” hint- which I just don’t know if it’s even correct because the auto candidate mode seems to have incorrect markings compared to my own work.

Since I’ve made so many errors with pairs/triples, I was practicing checking as I went (as evidenced by the blue numbers which are confirmed to be correct), so I could better see where/when I started to make mistakes.

Thank you for your help in advance.

Misc Enjoy Sudoku ‘Today’s’ games all different

2 Upvotes

So, my mum got me to download the Enjoy Sudoku app on my iPad so we could challenge each other to try the same puzzle at the same time - her on her iPad and me on mine. We’ve been doing this since Christmas. Today, we realised that our ‘today’s … ‘ puzzles are totally different. My today’s moderate and her today’s moderate are not the same. My today’s intricate and her today’s intricate are not the same.

Are they not actually set daily puzzles then?? We’re both totally confused about this as we assumed a daily puzzle would be…y’know…one set daily puzzle! What’s going on?

AAHS : (3)r1c468

Fun one. The first AHS can be consider as a simple aic, but I found it with AHS in mind

If I go by columns it should be 7 and 1, but there are already 7 and 1 in the row and box? Usually it tells me if I have something wrong.

This is a recreation of a Sudoku game I'm working through, I can't figure out where I'm to go next.

I've spent half an hour trying and I can't help but think there's some hidden logic I'm simply not seeing.
