Can You Solve Even 1 Cell Of This Sudoku??? SHC #66

In Can You Solve Even 1 Cell Of This Sudoku??? SHC #66 by Smart Hobbies, I will show you how to solve a Classic Sudoku called “The Big Qin” by Qinlux by using an expert Sudoku technique called a Hidden Quadruple. I solve this Sudoku logically by placing marks in the grid to include Snyder Notation and explain the solving strategies as I apply them. Thank you Qinlux for permission to feature your puzzles on my channel.

Thanks again for covering another puzzle of mine! It's always an honor to be featured here, whichever ones you choose! To be honest, I was definitely intrigued that you chose this one to cover, being a little older and having some reservations about the telegraphing of the first step, but I'm quite glad you found your way through it (relatively quick I might add!) and recovered from that small mistake too. Again, superb video, and very nice work with all the videos you've been putting out recently!

[@SmartHobbies]

Always a pleasure. Thank you for these wonderful puzzles. I picked it mainly by the name:)

Thank you so much for your continual support. I am glad you liked it.

[@AnonimityAssured]

Phew! I'm glad you noticed that major error quickly. Perhaps surprisingly, after the tricky break-in, no notation was needed for this one (29 = row 2 column 9): 29 (hidden quads in row 5), 28, 38, 25, 18, 37, 15, 14, 75, 11, 12, 78, 96, 56, 41, 23, 21, 92, 32, 31, 73, 85, 36, 35, 66, 54, 67, 48, 77, 57, 49, 94, 82, 53, 93, 74, 89, 81, 88, 59, 45, 95, 44, 62, 52, 65, 55, 68, 58, 61, 51, 91, 71, 99, 79.

[@SmartHobbies]

Me too. Thanks for sharing your solve path. I found this an interesting 1-stepper which is not Qinlux’s hardest but quite satisfying to break into.

[@JalenPlays]

Nice upload

[@SmartHobbies]

Thank you so much for watching. I appreciate the kind words.

[@laszloliptak611]

Nice puzzle and solve. Finished in 13:36. I filled in most of the candidates, which made it much easier to spot the quintuple in row 5. After that the rest of the puzzle is very easy.

[@SmartHobbies]

Nice job with the solve. Glad you were able to find the break-in.

[@alexanderstelmakh8906]

How can one get a clue that we need to find a quadriple, and, how, for hell do it on paper?

[@stegra5960]

Most likely just me being a bit slow but at 16:40 I can't see how you ascertained that the 7 had to be in r6c5/r6c6. Why not 95 at that point?

[@SmartHobbies]

Good catch. That is not a claiming pair of 7’s in block 5. Should have kept 7 in R5C4.

[@stegra5960]

@@SmartHobbies Not to worry. The puzzle was well and truly cracked by then. Just a little fortunate it wasn't critical.

[@JohnRandomness105]

Okay, I am thoroughly stuck. I found an empty rectangle in 6s and a finned X-wing in 5s. Right now, I've marked in a bifurcation point: either R8C9 is a 9, or I have a jellyfish in 9s -- rows 1, 3, 6, 8 and columns 1, 3, 5, 8. (It's a useless Sashimi finned jellyfish.) (Later) while I'd been hunting off and on for the quad mentioned in the description, it was a comment mentioning the particular row that led me to find the quad. I'll see what happens now. I got a pointing pair of 5s in block 6, placing a 6 in block 2. From then on, it was mostly unraveling the pencilmarks. Interestingly, R8C9 mentioned above contained a 9. 4:10 Was placing the 67 before correcting to the 37 the mistake referred to in the comments? 5:20 "That's a 56. Okay, that's helpful." Indeed, it was. BTW, R4C4 is 78, although it doesn't matter. 13:30 I see the mistake being corrected now, the 5 being removed. Thanks for the video.

[@SmartHobbies]

Great insight and comments. Did you see the similarities between this puzzle and Quarter Spin?

[@JohnRandomness105]

@@SmartHobbies Unfortunately, I can't remember the names of most puzzles, including Quarter Spin.

[@SmartHobbies]

@@JohnRandomness105 I released it a couple of weeks ago and has a slot machine on the thumbnail. It is also by Qinlux and also has a hidden quad. I thought you might have found The Big Qin through the end screen of Quarter Spin.

[@JohnRandomness105]

@@SmartHobbies I went back to it, and saw my rather long comment. I distinctly remember not noticing the third 6 possibility in a block where I penciled a 69 pair. It was one of the puzzles leading me to wonder about early dementia.
