This is the first video I am watching on your channel. I hit subscribe at 4:43. I love playing sudoku puzzles, and trying to learn this advance techniques. I have never seen such an simple and accurate explanation of this technique.
Thank you so much for the kind words. It’s comments from viewers like you that motivate me to keep doing this. I hope I can help you solve many more Sudokus:)
I'm a bit late to the party, but thank you for the easy explanation. Do you have a recommendation for a good sudoku app on android that supports colouring? I'm struggling with the harder puzzles on the app I use currently because you can't colour in it. Only way around I found, is taking a screenshot and doing it with the drawing tool in gallery.
Great explanation. All other videos don't explain it as clear as this. Have been watching your other vids for other techniques which haven't hit home for me yet too.
Thank you so much for the kind words. I am glad to hear you found value in this video. I have some tutorials that no other channel has ever featured, like 3D Medusa. What strategy are you looking at next?
@@SmartHobbies My limit for a while has been Skyscrapers/X-Wings. Time to step it up beyond that...I think I'm spotting some of the simple chain techniques, but not knowing what to do with them. Will take a look at the 3D Media, thanks :)
I did two of the three puzzles. The first (by unknown) was a walk in the park. The second (Air) popped up as my already having done the puzzle, and I didn't really wish to redo it. The final grid did have a few cells colored. The third was rather difficult. Once 49 cells began proliferating, I colored them. I placed a digit or two that way, and removed a few candidates. I found two finned X-wings in 9s, that did the work of a single pointing pair -- I only discovered that just now when checking what I did. I changed from coloring 49s to coloring 9s and not-9s. That got me a couple more digits. I spotted a 457 Y-wing that did serious damage to the puzzle. The final defeat of the puzzle was another Y-wing, in 479, where I used the colored cells to hit a target cell. (Fortunately, the not-9 in the particular cell was a 4.) I color positions that I use, such as finned X-wings and Y-wings. That way I can return to see what I did, and also backtrack to possible mistakes. 2:50 I didn't use color in the first puzzle, as I didn't need it. But I take it that your "conjugate pairs" are what I called 9s and not-9s in the third puzzle. (If a yellow cell not being a 9 forced another cell to be a 9, I colored that second cell blue. It went both ways. If blue wasn't a 9, yellow had to be a 9.) 3:00 I think that I would have argued that the last two cells you colored couldn't be 1 because they could see both purple and orange. Instead of coloring them, I would have removed the 1s. 4:40 I see two finned X-wings and at least three skyscrapers, all in 1s.
Nice job spotting the alternate strategies like the finned X-Wing, John. These puzzles had a couple of ways to go about it. In my next tutorial, coloring will be the ONLY way to solve 2 of the 3 examples.
With such abundance of clues (total of 35), this puzzle should be a breeze to most battle worn veterans! Let’s start with right column block : Right away we have [25] tcp on c9B6; 8 on c8@(58); 7 on c7@(37), leaving 359 triplet on c8B3; [34] tcp on c7B6. Next the bottom block : Right away 3 @(74), by row7/col 4; [45] tcp on r3B7 ==> 7 on r7@(72)!, in view of 7s given in Box 9& on c5, both off r7, leaving [29] tcp in Box7on c2 between rows 8&9, and leaving 2 on r7@(75), plus [47] tcp on r8B8, in view of [47] uncovered on r7& given on r9, both outside of B8, leaving [89] tcp on r9B8. We have done as far as we can logically go, noting that B7 is completed. Now we move northward : Note 1 splits in Boxes 145 and 1 splits on r2@(22)&(24) plus on c1 @(11)&(61), forming two ‘fractured’ Wings in 1 with B1 as the pivot. This implies 1 can’t be at cell(64) looking at both arms of 1 at (61)&(24). In plain language, 1 at (64) would result in 1 on c1@(11) and 1 on r2@(22), a No-No for having two 1s in same Box1! So 1 in B5 is at (56) and on r6@(61) => 5 on c1@(41), leaving 9 on c1@(11) and 2 in B5@(64) (how so?), and followed by 8 on r6@(63) ==> [18] tcp on c2B1, leaving 236 triplet on c3B1 ==> !! [36] tcp in B4 on c2, leaving [79] tcp on c3B4 !! => with 9 uncovered @(43), 9 squeezes into B5 @(55), leaving [48] tcp on r4B5, plus ==> !! [58] tcp on c5B2 bet rows 2&3, by virtue of 5&8 given on r1 off c5, !! leaving 4 on c5@(15). So the Middle Row Block is totally completed. Now onward march to Top Block : Note [17] tcp on r1 B2, by v of 1&7 given on c7 & uncovered on c3, both off r1. Also 9 uncovered @(11) hand in hand with 5 given on r1, both off c8 ==> [59] tcp on c8B3, leaving 3 in B3@(18) ==> [23] tcp on r3B1, leaving 6 @(13) ==> [26] tcp on r3B2 bet cols 4&6, by v of 2&6 uncovered on rows 1&2 outside of B2, leaving 9 in B2@(24). That should do it! All the open tcps are sure to be broken up by the respective danglers! It’s fun to go abt it. For instance, besides the [26] being broken up by 2@(64)&6@(66),1&9 uncovered at (24)&(56) will break up the chain of the remaining 4 sets of tcps , between the cols 4&6,namely 9=> 8=> 4=> 7=> 1, and vice versa. So in retrospect, once we spotted the presence of fractured Wings in 1 and nailed 1@(56), we are home free and the rest is history!
First one,kinda easy, done in 04:04. Second one, didn’t find much after first round of synder notation, but after coloring, I was able to spot the 2 string kite of 1, and figure out R2C8 and R2C9 is a 23 pair. Puzzle then falls apart from here. Solved in 12:18. Third one, I am not able to really finish it😅 I spotted the 49 pairs that are linked together, cross out 49 in every cell that is seen by different color cell, and filled like 4 cells, but was unable to continue to spot other strategy😢
I am glad you did the first two smoothly. I recommended you check out my solve of Bondye’s puzzle from the link in the description to see where to find the next step.
@@SmartHobbies Just finished watching original video, along with the comment section below. It makes sense to me now. Sometimes I can’t even reach the same starting position as the tutorial video for specific technique. So watching the full solving video really helps a lot. Thanks 🙏

great explaning...many thx

Very good tutorial. Nice to learn.

@@SmartHobbies You realize that you tossed out a challenge.
With such abundance of clues (total of 35), this puzzle should be a breeze to most battle worn veterans!
Let’s start with right column block :
Right away we have [25] tcp on c9B6; 8 on c8@(58); 7 on c7@(37), leaving 359 triplet on c8B3; [34] tcp on c7B6.
Next the bottom block :
Right away 3 @(74), by row7/col 4; [45] tcp on r3B7 ==> 7 on r7@(72)!, in view of 7s given in Box 9& on c5, both off r7, leaving [29] tcp in Box7on c2 between rows 8&9, and leaving 2 on r7@(75), plus [47] tcp on r8B8, in view of [47] uncovered on r7& given on r9, both outside of B8, leaving [89] tcp on r9B8.
We have done as far as we can logically go, noting that B7 is completed.
Now we move northward :
Note 1 splits in Boxes 145 and 1 splits on r2@(22)&(24) plus on c1 @(11)&(61), forming two ‘fractured’ Wings in 1 with B1 as the pivot.
This implies 1 can’t be at cell(64) looking at both arms of 1 at (61)&(24).
In plain language, 1 at (64) would result in 1 on c1@(11) and 1 on r2@(22), a No-No for having two 1s in same Box1!
So 1 in B5 is at (56) and on r6@(61) => 5 on c1@(41), leaving 9 on c1@(11) and 2 in B5@(64) (how so?), and followed by 8 on r6@(63) ==> [18] tcp on c2B1, leaving 236 triplet on c3B1 ==> !! [36] tcp in B4 on c2, leaving [79] tcp on c3B4 !! => with 9 uncovered @(43), 9 squeezes into B5 @(55), leaving [48] tcp on r4B5, plus ==> !! [58] tcp on c5B2 bet rows 2&3, by virtue of 5&8 given on r1 off c5, !! leaving 4 on c5@(15).
So the Middle Row Block is totally completed.
Now onward march to Top Block :
Note [17] tcp on r1 B2, by v of 1&7 given on c7 & uncovered on c3, both off r1.
Also 9 uncovered @(11) hand in hand with 5 given on r1, both off c8 ==> [59] tcp on c8B3, leaving 3 in B3@(18) ==> [23] tcp on r3B1, leaving 6 @(13) ==> [26] tcp on r3B2 bet cols 4&6, by v of 2&6 uncovered on rows 1&2 outside of B2, leaving 9 in B2@(24).
That should do it!
All the open tcps are sure to be broken up by the respective danglers!
It’s fun to go abt it.
For instance, besides the [26] being broken up by 2@(64)&6@(66),1&9 uncovered at (24)&(56) will break up the chain of the remaining 4 sets of tcps
, between the cols 4&6,namely
9=> 8=> 4=> 7=> 1, and vice versa.
So in retrospect, once we spotted the presence of fractured Wings in 1 and nailed 1@(56), we are home free and the rest is history!
