Thanks for getting me into hard sudokus! I'm not British, but now when I'm solving a puzzle, I speak to myself in proper English, and murmur things to myself like "so, threes, look", "that places the two here", "and now these eights mean that this square cannot be an eight", "and now immediately I'm looking at this row", "this is very nice actually", "and now, look, this square sees a seven, so that fixes the five here", "look at this, this is a very nice pattern here." Cheers!

This channel has been teaching me so much, and it's great to feel like it's all slowly integrating into how I solve these. Thank you, Simon, for teaching me to crack what once was utterly cryptic.

As usual, I put you on hold as I would go ahead, and only once did I let you go ahead and point out, mmmm I forget where, but I know I could have figured it out before to much time would have passed. It reminds me of when I learned to snow ski. At one point I hit a wall, well I mean I was not getting any better. Then I went skiing with an expert, and I followed him for two runs, and walla, I was an expert. Thank you for letting me follow you. I may not be an expert, but, I'm a lot better than I was yesterday. Probably still an intermediate. I'm one of those guys that "can't see the forest, for the trees". Thanks again.

I had a great time. Once I sorted out the first set of 8 x-wings, there were 3 groups by the way. Then I found a couple of 9 x-wings. In the end, I was moving so fast to solve the rest of the puzzle, I figured I had goofed. I didn't it all came together, beautifully. I found the naked "1" earlier in the solve. I had just finished putting several numbers and pencil marks. I was at a roadblock. I remembered that Mark said that he would do a quick scan for naked singles. So I did and it worked. What a great puzzle and a terrific tutorial. Gene

The good news is I've not made mistakes filling in everything else, so I'm getting better at basic notation and technique, I usually mess something up somewhere along the way but this one was smooth sailing. Great puzzle and video as always :)

whenever i'm able to limit a digit in a row/column to exactly two squares, i have noticed that without even thinking i start to look for a second row/column where i can limit the same digit to the same two columns/rows. that's how i found the X-wing on 8's in this puzzle. now this new "involuntary habit" of mine may waste my time in the long run (looking for a row/column in puzzles where there are none), but it does mean that i almost never miss an X-wing!

Very interesting puzzle. One extra thing I spotted that I thought was cool was once you got the first X-Wing on 8s it allowed you to pencil mark 8s in all 4 boxes, creating another X-Wing on 8s in rows 2 and 4 of collumns 1 and 7. Then once you got the 39 pair in the bottom it forced the 7 into the 2nd X-Wing which ended up solving both X-Wings.

Hi, sorry if this may sound like a dumb question, but around the 16:10 minute mark, you filled in that 8 on R1C3, how did you immediately conclude that it was a 9 beside it? Within that row the 6-9 pair could still be in the 2 open positions being R1c2 and R1c9 or did I miss something. I only recently got into Sudoku and am slowly learning and this part really confused me as I attempted the puzzle and got stuck around this part.

After the 8 X-wing restricts the 8s in the bottom right to the 7-8 pair, I noticed the other 8s now forms another 8 X-wing in r2,4 and c1,7. This second X-wing is "entangled" with the first because they are in the same 3x3 boxes. I call these "entangled X-wings" (from quantum mechanics' "entanglement"). This occurs in the video about 11:00

After watching this with the idea of only 2 digits for notes, it has been great. There's times I'll use 3 but only if it's a straight line or I've been left with no options. The reason is my eye hand coordination disability and ADHD make it that I can't see the hidden singles. On the harder puzzles I'll clear out notes and going through the numbers again has been very helpful. Thank you.

Took me 35 minutes, but almost the same order. Pencilmarking has a huge impact on speed. I used to put 1-9 in their relative position in each square, which doesn't give room to the center marks. That and restraining myself not to put everything in helps so much with getting a clear picture and not cluttering too much.

It has to be in r2c1 otherwise there wouldn't be a 7 in c1.

Is there a swordfish on sixes in boxes 2,4 & 9? I've tried to see if I could figure the swordfish technique out but I'm not able to see which columns they would be in.

28:32, spotted the x-wing pretty quickly! Unfortunately i then just missed that my notations had revealed a digit and stalled for a while, but still very pleased

It only took me less than a hour to do this puzzle, but a couple of months ago, it would have taken longer, a lot longer if I hadn't given up. Mark and Simon, thank yiou, thank you, thank. Now I'lll have to convince the lady boss to let me join "the club." That shouldn't be very hard.. Maybe I'll splurge and join the $3 club.

This was very unusual. Right at the start there were 5 matching pairs and a triple, all in the center vertical boxes (2,5, and 8). After eliminating a few numbers by following Ariadne's thread, I found 2 sets of bare quadruples, both of them leading to hidden triples. After that the thing just unraveled itself. WOW!

Just over 34 minutes. Got the middle rows quickly, then stalled out for a bit until I figured out the x-wing implications.I was happy to spot the 39 pair in the bottom left, then stumbled home from there.

1:14:56 on this one... Spoilers below (if anyone is concerned about spoilers for a 2 year old puzzle). However, the proper breakdown of this one could probably be most accurately divided into 20 minutes of easy progress (everything up to the naked 1 in box 9), ~45 minutes of desperate bifurcating/mapping out cell options, and then 10 minutes of cleanup after finally noticing the 8's x-wing in Row 1/4... What might have been if I'd been slightly more observant and not tried desperately to break the very appealing pairs in R3C1/R3C7/R7C1/R7C7 instead :/ It's possible that there is some sort of way to solve the puzzle without noticing the x-wing, but idk how it could possibly be done without chaining multiple bifurcations together and looking for some sort of logical break (or another trick I've forgotten). It was possible to get down to quite a few more restricted cells from the point Simon reached around 8:00, but the aforementioned 1 in R7C8 was the only concrete digit I was able to lock in in that 45 min span lol :P

I am happy that my X-Wing skills have improved. Took me just under an hour to finally spot that 7 in row 2, but I got there eventually.

11:48, without noticing the X-wings, which is probably why it took me a bit longer than it should have. :) Nice puzzle!

Back to the classics - good - I can do these (eventually - 2nd attempt - took ages) if I can find x-wings or empty rectangles. More killers?

I took two goes at this puzzle. The first time with well over 30 minutes and I couldn't find anything. Watched the video and as soon as he mentioned the similarity in the two rows I immediately knew he meant an x-wing. I paused the video at that point and restarted the puzzle. I finished in just under 15 minutes with that one hint.

good puzzle for spotting different kind of things because you won't solve it using only snyder notation. nothing really difficult though. solved in 11:52

Simon, when you discovered the 8 'X' then a little later proceeded to enter an 8 in the top corner of the middle-left block, how did you determine this seeing how the position of the 8 in the 'X' box ie lower right box of the middle-left block remained a possibility. The finished puzzle was correct but I couldn't resolve the 8X until much later.
@jesscarrier4180

If I understand your question correctly... putting an 8 in the top left corner of the middle left box resolves the green x wing because the middle left box can only have one 8 in it. Therefore the 8 in row 6 must be in the right x wIng spot.
