Thank you! This one was even harder! I think the next one will be really easy...

@22.15 Couldn't understand the logic of putting 4 in R5C4. As there may be 8 in R5c6 besides in r5c3 & r5c7.

[@ChazK3-SudokuHard]

r5c6 cannot be 8, because r5c3 and r5c8 can only be 1 or 8.

[@jawaharlalgupta9039]

😂so u put 4 in r5c4 and hoped it to be right. A guess?

[@ChazK3-SudokuHard]

I knew it would not come out clearly, but it is not a guess. r5c8 can only be 1 or 8. And that forms 1-8 double with r5c3. r5c8 cannot be 3 or 7, because they will be used in c9 part of box 6. I tried to explain it better with my other "walkthrough" video at: kzbin.info/www/bejne/pJnTq6moosqUhKssi=KnHwRsEewqN55W-3&t=595
