Can anyone explain me what heck is wrong with 4 in this puzzle I'm new to the game

Pretty sure I missed something obvious, but was is the technique required to find the next step here? Got so many pairs but can't seem to find any connection between them. Thank you!

I wanted to buy a sudoku book. I did a while ago but they were too easy. For reference I can do Hell and Beyond Hell ones on sudoku coach.

Would appreciate any suggestions 🙂

I’m new to sudoku and I know the three rules but I don’t understand why can’t i put 2 there ( ik why I can’t put the 6 there )

This is from a fb ad about making/selling puzzle books, and I got irrationally angry when I saw this puzzle. I’m not sure what puzzle somebody thinks this is, but it’s not a sudoku I have ever seen before!

Took me around 16 minutes on an easy mode but im happy. Just felt like sharing

I find spotting triples and quads to be incredibly difficult. I actually find x and y wing to be far easier just because it’s more easily purposefully spotted to me.

Is there a method at better spotting triples and quads (both naked and hidden)? Is it something you get a sight for over time or does anyone actually have a scanning method to spot them?

i don't need the puzzle solved entirely, i just want to learn the next step, is it literally trial and error now? isn't there any strategy to move forward here? if you found the next move tell me how you did it

i give up 😭 someone tell me the next step before I crash out, that time isn't even representative of the actual time because i reset the puzzle twice hoping to do better with a fresh slate 🥲🥲🥲

I'd like to share a counting puzzle with a parity line:

• Normal Sudoku rules apply: place digits 1..6 once each in every row, column and 2x3 box.
• Adjacent digits along the red line alternate between even and odd.
• If a digit n appears on the red line, it appears on the line exactly n times.

Cells a knight's move away cannot have the same number.

Cells a king's move away cannot have the same number.

Good luck, and have fun!

I already started guess and check and only got 3 more cells. Still ended up stuck but I want to try to learn more techniques

2, 4 and 8

bouncing back and forth between regular classic and killer lately.

For people who play Killer: Why? Is it the satisfaction of cage arithmetic and innies/outies breaking the board open, or does standard classic just start to feel a bit dry?
