Expert Sudoku Skills: Hidden Pairs

[@wandrea76]

Your videos is the best sudoku solving videos on KZbin. I learn a lot from this channel.

[@amarnathmohan1624]

23:14 Got the 36 and the linked 13 without noticing the pairing. Great videos! Can't wait for more sudokus!

[@tonyawright6020]

The 7 in column 1... after a while I was thinking, he's going to work around to that being the very last thing he does, isn't he? And sure enough...

[@groove_holmes]

35:45 - good reminder to focus more on rows/columns initially than just trying to find pairs inside boxes which is my usual M.O.

[@Tolle44]

Took me a little under 45 minutes to solve. Simon, you really are a fast solver! And perhaps sometimes too clever for your own good. There are several instances where you seem to overlook "mortal methods" and go on with your next level solving techniques. I'm inclined to suggest you pay more attention to your own notation, but I'm not sure if you'd actually solve faster. A few examples: the isolated 9 at 10:40, the naked 7 at 11:00, another 7 at 12:00, a 45 pair at 14:38. This is by no means meant as a critique. Solving these puzzles in the perfect order is nearly impossible, but it becomes so much more obvious when put on video where the viewer isn't performing and has all the surplus in the world to single out mistakes. Thank you so much for your videos. I personally love classic sudokus and chess-inspired sudokus. Looking forward to your uploads all the time.

[@mydoggylives]

Gotta say... that trick with the 3/6's and the 1/3's was brilliant! I spent 14 minutes on it and had everything possible... even the 8/9 and 1/8 in Column 8 and I decided to stop and just come back and watch the video. I realize now I would've never have gotten it.

[@memomg2811]

You're truly helping me get better at sudokus. Thanks!

[@barneytrubble]

I couldn't see the hidden pairs the way you did, but filling in the numbers meant I saw the quadruple 1289 in column 8 that led me to deduce the 36. Likewise I spotted a quadruple on row 7 also.

[@rodrigoneves135]

That was fun. I Liked the initial setup of 4 "arrows", looks very appealing. Also enjoyed that you spent a little more time going into detail on the tricks and how you spotted things. Bought the sandwich app yesterday, it's very nice and I will certainly recommend it, it also made me realize that the bigger the screen I play sudoku on, the more prone I am to not picking up on those sneaky "simple" digits, like those 7s in c1 that you left there till the very end.

[@jorgkuijt4735]

I Guess I'm not the only one who watches the first bit of the cracking the cryptic videos, just to learn about the rules..Had a go at the puzzle, and returned to see how it's done..:P

[@valeckseimu3132]

The miss single at 11:06 makes me yell so bad that I immediatly apologies to pixel Simon, even if he keep missing the resolving 7 in the grid

[@Chriib]

yeah, and he waited to the very end of the video. This can be so frustrating.

[@inlove4rock]

he is doing it on purpose.... u are looking at the video like fools... is a trick he is using. i unsubscribed

[@Chriib]

@@inlove4rock now why would he do that? What would be his purpose?

[@inlove4rock]

@@Chriib so your brain will want to watch until he is solving the missed digit... :)

[@Chriib]

@@inlove4rock Well, I don't buy it.

[@matthew456turner128]

25 minutes for me. The interaction of the 2 hidden pairs was the key to unlocking this puzzle.

[@ianpearse4480]

A great hour spent doing this one. Very cool puzzle.

[@mayanksitapara9651]

19:12 Title helped a lot. Took lot of time in filling first few digits. It was relatively easy after that.

[@AlexFry01]

31:32 a long time to actually get going (and a few times missing a digit could already be placed without noticing), but once that 13 36 overlap came it all followed through nicely

[@RandomBurfness]

17:00 on the dot! Nice puzzle as always from Sam Cappleman-Lynes! Speaking of classic sudokus set by Sam Cappleman-Lynes, how likely is it we might see puzzles from him in the recent Classic Sudoku app update?

[@eternalblasphemy6526]

Spend 40 minutes finding the bent quadruple. Once found, it is a pretty straightforward sudoku (still took ~ an hour to solve as I've slipped up once).

[@Tahgtahv]

Several times where a digit could have been placed much earlier due to that number already being in a row/column and in one case at least a box even.

[@christianjalexander]

I saw the same thing. I felt like Simon was distracted or something while doing this puzzle. 😆

[@inlove4rock]

he is doing it on puprpose

[@goldenera7090]

20:02 for me. found 1,3 and 3,6 pair earlier and moved swiftly. took time to identify x wings on 8 later...otherwise all same.

[@catnip420]

I solved it myself, but only because of the title. I knew what to look for, I'm sure I'd miss those hidden pairs otherwise.

[@onurguler1863]

The speed of Simon finding those pairs always amazes me :D Thank you for a great video as always. I found the 3-6 pair on the R2 and 1-3 pair on R7, couldn't spot the 3-6 pair on column 8 for a long time. 5-8 pair was hard to spot as well :(

[@alkz0r381]

37:05 for me... hard struggles at the start but afterwards it was a joy to solve

[@LeCrenn]

Took me 45 minutes, but the hidden pairs clue made it pretty straight forward. I'm just not very fast at this.

[@wizzolo]

this one took me ages :o particularly to write in the first digits, I'm always impressed by how simon makes it look easy

[@MartsGarage]

30 mins in and not a single digit. I'll watch the video now and see if I can get a start at least. Edit: finished at 1 hour 41 and loads of help from the video. Thanks. Mart.

[@isabelsong21]

20:38 for me. Did not notice that trick with the 8s!

[@AmyDaisy69]

This one was quite straightforward.

[@DevilishlyDutch]

So I missed the first hidden pair, but then I found two others on my own, so that's good progress! Didn't spot the 58 cell to complete the other hidden pair later on though, which was the last one I needed to solve the puzzle. But I'll take it! I spotted 50% of the hidden pairs I needed

[@9797nikola]

i just needed to look at 5:37 and i started solving no problem i didnt spot the new york and from there it flow nicely

[@cryiin]

I just keep yelling at my screen, when you don’t finish rows or boxes with one digit left. OCD kicks in hard :P

[@paulcrumley9756]

"That puts a seven in these two . . . " Me: LOOK TO THE RIGHT!!!!

[@pietndala7394]

One of my few finishes, 63 and 13 pairs

[@NelielSugiura]

Not really fun when I am twenty minutes in without a digit to be found. :( Think I will just watch this one...

[@BryanLeeWilliams]

Same

[@glennmelven3414]

I went 27 minutes without placing a digit, watched the video till he got the 36 pair in C8. Then I managed to solve it after another hour. 1:36 total time.

[@RealCadde]

It's that bloody new york trick. I just can't spot it. But i got stuck a few more times, mainly because of temporary blindness.

[@kenadigwe2917]

34:38 just had dinner so I was pretty much half asleep for this solve

[@f.w.7843]

12:56 for me. There were actually 2 36 pairs. Simon could have saved himself quiete a lot of complicated working out had he spotted the 7 earlier.

[@sabetwolf]

28:44, though i needed help to start. devilish!

[@djstarr1997]

We really had to wait til the end for him to place THE SEVEN 😭

[@jaguh9069]

26:55 Wow can't believe I spot it and completed the puzzle, the title kinda spoiled it so I was looking for pairs all the way.

[@elrerex255]

31:47 On my own, Yeah!

[@tomekduresov706]

Exactly 30 mins, missed a million things, but atleast I solved it.

[@zynzane9680]

Worked it along with you but wish I could see everything you see!

[@no-feetmcgee5577]

When the first digit you spot that he misses is literally the final digit he fills in.... :P

[@pierrenilsson6189]

And yet he solved the puzzle a lot faster than I did :(

[@familyupgrade]

Finally, after at least 15 min, I saw the first pair. Then I got the title. There are A LOT of pairs.

[@Josh-cd3zf]

That was a very hard Sudoku. It took me 16:41

[@UofMFan628]

27:06 took me forever to spot the hidden pairs (there was also a 36 pair in row 2)

[@rabidsamfan]

5 minutes to place the first digit, but once I got started it went okay. 22:23 to finish. Now let me see how Simon solved it.

[@sunriselg]

26:34 - had a bit of a stall here and there, despite the spoilers in the video title.

[@RealCadde]

11:00 "So this cell must be 78" ... And as usual, you are missing the obvious.

[@RealCadde]

12:07 "Must be a seven in one of these two squares" If only there was some way of telling which one...

[@binarybox.binarybox]

@@RealCadde Should have followed through with the 7...also should have followed through with a 5 later on.

[@lawillerton]

10:45 Nines in the top row, when I seen it I was on a run away...

[@Coyotek4]

37:31 I'll take a solve over a non-solve any day, but I was very slow to finding the hidden pair, even knowing the title of the video.

[@keyurbhogayata1291]

10:19 yes we can hear noise coming from the aeroplane lol

[@luketurner314]

33:48 Took me half an hour, but with only the "hidden pairs" hint in the title

[@pascalpp]

10:11 Before Maverick was called “Maverick”

[@bpickerell]

Second puzzle in a row that he missed resolving a number half way in and filled it in during the last moves. He could have filled in all the 7s way earlier.

[@megaminxpll]

After that first hidden pair (i found the same) , it was just basic stuff rest of the way, 5:09

[@drex5242]

17 minutes, I was going crazy until I saw the 3’s and the 6’s

[@noelmarttinen4190]

First one I was able to solve, took me 31 minutes.

[@CCHdennis1]

47:19 spent 20 mins to find out the first 36 pair, but then 1 in box 9 could only placed on R9, so solving 1 on box 7. then everything solve. But actually I'm not using hidden pair. lol

[@stefantitus-glover9686]

Anyone got/ know good videos to explain some advanced techniques like Jellyfish, Swordfish, finned swordfish etc?

[@alkz0r381]

There is a quite detailed tutorial on YT, check out Sudoku Swami if you are interested. Many given examples there, maybe it helps you. At least I learned a lot from those videos

[@rodrigoneves135]

I second this request.

[@WolfBerserker13]

wow can't even get a start on this one

[@pietndala7394]

Improvement, 11 minutes 😂😂

[@aoitenshi1]

49:48 Although I was kind of cheating because I was actively looking for a naked pair. I might have not been able to solve this one otherwise.

[@martinarcher1503]

i can see the first 1 is valid at 8:10, but not how Simon can conclude the 36 pair in c8r7 is resolved as a 3 at all? The logic only proved the position of the 1 surely

[@msolec2000]

Because now that the 1 goes in column 2, where does the three go in row 7?

[@chaotix37]

26:40. I realized that 36 pair is the starting point anf 13 clashes.

[@user-A168]

Best

[@Yinception]

The 3 in the middle box is wrong. There are 2 threes diagonally -_-

[@remigregoire2219]

I really wish I had something clever to say here, but I just watched this.

[@edwardhudson815]

12:46 why did he do it like that? surely he should have put 5 and 8 in the other 2 boxes as well

[@jons288]

This took me 3 hours and 33 minutes, with several screw ups. Not easy to spot some of these pairs.

[@MubarkAlKhatlan]

it took me 1:46:00

[@Greg-TC]

10 minutes in with no cells filled in... fuck this one's hard to start

[@Viernes13punto5]

6:08 how did you know only a 1 or an 8 could go in that box?

[@heymattswag1513]

Only 1,2,8,9 could be placed in that column, as there was already a 2 and 9 inside that particular square it meant only 1 and 8 could be placed.

[@pietndala7394]

Missed 7 in column 1 dragged the game

[@dczzzz55]

40 mins -afer getting nowhere I had to watch up to the point when you said 'New York Times type trick' in order spot the 36 pairs in row 2 and col 8 myself

[@sudokuvariante]

It took me 4'41 to solve it. Nice sudoku. It made me remember about this one: sudokuvariante.blogspot.com/2015/08/sudoku-classique-n72.html that has same configuration of digits (and is probably a bit easier?).

[@waffles_yes1379]

Its 4 o'clock in the morning and I'm watching some random dude do Sudoku puzzles. How the hell did I get here

[@robertan.2491]

pandemic

[@andreww4473]

Is it only me, or do others have ads popping up every four minutes? It's worse than ITV. Quite annoying really - missing things while trying to remove the ad.

[@MaxMcEvoy1178]

too much preamble. "Let's get cracking" starts at 2:49

[@BryanLeeWilliams]

Too hard for me. But I enjoyed the solve.

[@LisaLaMagna]

I am here to learn what a hidden pair is, and I still don’t understand,

[@zach_neill]

He explains how to use it better here: kzbin.info/www/bejne/qpayiZqgiLBqrKM. Basically it locks those two cells together so that whatever number the one is, the second is the other. It limits the contents of the two cells to just those two numbers and can help eliminate possibilities in the row/column/block that the pair exists in.

[@thepimentninja7340]

It took me only 1 hour 40 lol
