Example #2 also doesn't seem right. You say 5 cells but 458 is only in 4 of them. You also don't have the 1 showing in the first box only the 3 and 7. Box 3 can't have a 3 so how does that make it a 137 triple? What you are showing and what you are explaining are not matching.
Great question. The 3 candidates 1,3,7 do not need to appear in all 3 of the purple cells, but that the 3 candidates do have to be limited to those 3 cells in the row, so you may have a 3 or a 7 or a 1 in just 2 of the 3 cells or all 3. Hope that helps.
Example #1 makes no sense how you determined a 7. Your choices for the two squares in question are 4, 6, 7, 9 and 5, 7. Why aren't you considering the 5 in the choices? The square you chose to be 7 could also have been a 5 so how did you eliminate 5 as a possibility? 5 is also a candidate for square 3 with 4, 5, 6, 9 as choices.
Great question. For example 1, the 4,6, and 9 in row 6 have to fit into the 3 purple cells in block 4, which leaves only 3 cells in block 4 available to be a 7. Since we have 7s in columns 1 and 2, the only remaining place to put a 7 is in column 3, (R6C3). If you put a 5 there, then there would be no place to put the 7 in the block. Hope that helps.
@@SmartHobbies DOH! I see, if you put the 7 in 53 then the 9 must go in 43 which means there is no place for the 4 or 6 so the 7 has to go in 63. And I just now realized those 7's form an interior X-wing with squares 57 and 67 which forces that 7 into 57. I originally tried X-wings from the ends but it busts the puzzle leaving missing numbers in the interior.
That is cool. I love that you check out the puzzles. I usually let the video play if on a laptop while I solve, to see if I can beat the video 😏 Which puzzle gave you the most trouble?
@@SmartHobbies I think the 2nd. 3rd was super easy. I'm not good enough at recognizing the advanced strategies to ever really beat the times. Plus there's a lot of diabolical strategies that I've never tried to learn yet. I don't solve while watching vids, since there's a lot of strategies that I haven't tried to learn yet. So I listen to the reasoning.
@@mrDingleberry44 nice insight. Whenever you are ready to go down the diabolical path, I have plenty of tutorials to choose from. I’d recommend starting with X-Wing and Skyscraper tutorial and go from there. Happy solving.
I lost a rather long comment about example 2. Sorry, I don't want to rewrite it. Hours later: I did example 1, beginning as the initial screen showed and placing the 7. Repeating the process in block 6 gave a different result, but I still placed a 7. Similar happened in blocks 2 and 8, also placing 7s. Block 3 was all bivalue cells, and gave me two triples to narrow blocks 1 and 9. Block 7 was also all bivalue cells, but no triples. Instead, it placed the 9 in row 9 and the puzzle collapsed. I saw that I'd already solved the third puzzle. 15 1/4 minutes was rather quick for me. 2:20 I remember that row from Example 2 -- in fact, the *quad* there stood out in my mind. I'd only partially fulled it out, with 458s in R7C8 and R7C9 and 4568 in R7C4. Based on a casual view of the digits facing it, I penciled in R7C6. My hunch was correct, and it was 4568. The quad gave me the 1379 quad. I didn't notice that the 9 was placeable in R7C5 until much later -- I didn't notice the 19 pair together with the 1 in block 8. 3:00 Um, why the quint and not the quad? 5:50 I don't think that I watched the video, although I did the puzzle. I would have noticed the irony of my comment about obvious things like the 123 triple. That hidden triple was "hidden in plain sight".
@@SmartHobbies I played the hand, getting quite stuck a good part of the time. You spoke of triples, but didn't mention quads, which I encountered in the solve. Several situations were there for a long time before I noticed them.
@@JohnRandomness105 it is interesting and understandable that you would see naked quads instead of hidden triples. For me, what and how I’m marking will usually determine which strategy I see first.
I'll have to review the 3rd example as that's what generally trips me up when doing the various 'extreme' ??? that you find online. Example 1 & 2 I use without assigning a strategy/technique to.
@@brucewayne2091 I was watching Rangsk solve one yesterday, and there was a hidden triple right from the starting grid. Do you seem to notice them with those puzzles?
@@SmartHobbies Rangsk: unshackling? Haven't seen it yet. I generally load up any classic sudoku & play thru to the end or to a point where I get stuck. However, I'm always puzzled why a certain # is the correct pick when you see what looks like a triple mixed into a quad.
