The Simple Trick For Hard Sudokus

Before watching this puzzle I'd never figured out how to find hidden pairs. I genuinely learned something in today's puzzle. This video should be flagged as essential sudoku learning material.

His pattern finding skills are off the charts

First digit after 16 minutes, whole video is 22 😅 what a key to the puzzle

"When you see extremely intelligent people talk about difficult things, the fluency with which they do it is so impressive." Pretty much sums up your videos, Simon!!

Solved it! Used 2 pencils, a blowtorch, a couple eyes of newt, a rebuilt Flux Capacitor, beef jerky, and a realization that "there is no spoon." Once the owl bobbinsed out of the radio and we filled the tires with pie, we discovered my preciousssss, and the hidden pairs leapt out like dark from night. Easy peasy. Well done Simon, brilliant as always. Marking this for re-watch to learn how to spot those hidden pairs in less than 13 days with a reverse time loop.

His pattern recognition skills amaze me. I would have never been able to solve this sudoku without those big hints of hidden pairs. Kudos to Simon.

Looks at the video length ..."hmm, 21 minutes, I'm havin' a go of this..." 4 minutes later..."nope, nothing!" 🤗🤗

I just LOVE how polite and kind Simon is - a pleasure to watch you solve!

A Paper Tiger. Never seen a puzzle with such a difficult break-in collapse so quickly and completely. Sadly, I wasn't in the mood for a difficult start, so I let Simon do the hard work.

I absolutely adore those rare and short moments between "sorry, this is not going well" and "oh, this is interesting". Applies to almost every "classic sudoku" type of puzzle being solved by Simon. My most recent hobby, thanks Simon!

At 13 minutes I was questioning whether this was part 1 of a multi-part series lol Well done Simon !

15 minutes in. Not a single digit placed. Time to see how Simon does it. Edit: Wow. It seems so simple but I wouldn't have spotted it in a million years. Thanks Simon. Oh yeah, nice intro.

My time was 36:46 on this one, and I've got Cracking the Cryptic to thank for that. A year ago I knew precisely zero sudoku techniques, not even naked singles, and now I'm spotting two swordfishes leading to a hidden triple <3 You guys have my undying gratitude and utmost respect. Still, despite solving it, I'm glad I watched the video, that two hidden pairs was new and amazing to me. My pathway was already described by other people in the comments, I did the swordfishes on 2's and 7's, which allows you to spot a 1/5/6 triple in row 8. That btw, interestingly enough, creates a naked single seven in box 9, so my first digit was r8c9=7. Simon's first digit in r8c1=4 came much later for me quite intriguingly :D

Nice to have a puzzle that doesn't require solving a system of equations to start ;)

You ran out of gas on the 4s while you clearly still had to half a tank...

Sweet home alabama was the last thing I expected to hear during this into

Really love when Simon gets out the guitar

I loved that one. It was like seeing a lock being picked.

Wow, Simon really can play the guitar.

This was definitely a puzzle to highlight the importance of hidden pairs. There are also a couple of swordfishes on 2's and 7's in rows and columns 1,5, and 9. However, the puzzle is more quickly solvable by spotting and using the hidden pairs instead.
