Truly Simon. "Can't see the trees for the forest." He misses stuff like this regularly, but also regularly sees stuff "instantly" that takes me minutes to understand, let alone see. Even when he does finally spot the 6 in the middle.....cleans up the box....and leaves the pencil mark 9. @35:00....comments on James brilliant progression with the 2....and 3....then ignores the 4 pencil marks (which could've been done via the 56 pair, or the 2 & 3)....but notices stuff on the far side of the grid. Even when he returns to box 9 -> 8 logic....still doesn't see it. But again, continues spotting much more complicated stuff without hesitating much. Such as at 37:27.....uses the "chaperone" trick (not that complicated) to place the 9.....but the 6 in row 3 does the same thing in (imo) a slightly easier to see way. At 37:56, "I can place 4 in box 4". Yes, with excellent logic....or just place it in box 6, then box 4. And, finally...after doing a few more 4's....points out the x-wing on 4s and STILL overlooks the 3/4 conflict in box 8. All that said.....it is a great way to learn! Loving it!

40:22 “we could have done that a different way.” Meanwhile, my wife is wonder what sort of video I’m watching that is driving me so apoplectic. That 4 was trapped from 35:08 onward.
Still amazed by how fast Simon manages to forget rules literally right after using them. Cant put 3 next to 1, places 3 next to 456 and doesnt immediately say so that is a 6
No, that's how I attacked this. There's one pattern (of course possible to rotate or mirror it) for 5,4/6 ,3/7 or 2/8 in the middle, and 3 for 1/9 in the middle. Only one pattern gave the 9 and 1 position that the diagonal needed.
@@henk-ottolimburg7947 I don't think I explained what I meant very clearly. I mean that adjacent digits cannot be of the same entropy (1-3, 4-6 or 7-9) so if you ignore the values and just map the entropies, each box has very few possibilities (in fact in the finished grid there are only 2, disregarding rotation etc). For example: - Box 1 has 4-6 in a downward chevron shape, 1-3 below that in another downward chevron, and 7-9 pointing up in a double-height chevron. - Box 4 has 7-9 in diagonal positions, 1-3 in a north-west pointing double chevron, and 4-6 in a south-east pointing double chevron. Those are the only two box layouts (I think they might be the only two that are physically possible) which isn't a huge help initially but once you start to get _some_ digits in the grid, you can very quickly start to see where the entropies must lie.
@@bobblebardsley Yes, I came here to say the same thing. There are only 2 configurations of low/middly/high digits within a box, and after some time that becomes a powerful tool for quickly filling boxes with digits!
WOW. With basically 2 rules and 1 given digit. You might as well call it a Miracle Sudoku. This puzzle is more of a discovery than a constructed puzzle.
At 8:50 the only thing I can think of is: Is that all the rules!? Let's see how this gets cracked! Edit after the break in, the way that the three in the corner is breaking symmetry is quite unexpected 🤯
33:07 First I didn't realize what straight meant though the different of 3 is quite forcing Then I realized the difference of 3 only applies within boxes And then I peeked at the video and found out what straight meant And the I still thought it was impossible, but somehow it solved! Rollercoaster of a puzzle
If Simon focused on completing a box rather than corner-marking the low digits, he probably would have noticed the roping in both directions throughout the grid. That really sped up my solve.
That was unexpected, this design w/o the given has only 2 solutions+2 mirrors w.r.t the D- (4 soln total). 7 boxes are completable leaving pairwise soln in the last 2 boxes diff by the given 3. Not having the constraint across box orders fooled me at first tho
43:31 for me - I got stuck at the start trying to figure out which line was the arrow; I was caught up in checking how the 3 would affect the arrow that I didn't check how the arrow affected box 7.
U can try stripping the antisymmetric components(the given 3) Orient yourself with the line...and then DD where the given 3 goes and reorient if needed
Definitely outstanding construction. Innovative, stratospherically cool and drastically minimalistic. Thank you *James Kopp* for designing it and thank you *Simon* for featuring so many *cosmic class* artworks on this channel. I hope this will be included in the next *CTC Cosmic Hits book.* 👏👏👏👏👏👏👏👏👏👏👏👏
Slowly savored this sudoku in 04:03:46. That included a subtle error discovered about 2 hours in that forced an almost complete reset. Extremely enjoyable puzzle though! I got a lot of work done thinking about box middles. Except for 1/2/8/9, each digit requires am exact set of four surrounding numbers when placed in the middle of a box, so if one of those four is already placed in a corner, it immediately eliminates that option from the middle.
I finished in 43:02 minutes. This was such a fun puzzle and a surprisingly smooth solve, considering the sparseness of the grid. I think my favorite part was the break-in utilizing the 3 in the corner to prove which side of the board the arrow was on. That was so fun to see. The rest felt very smooth as well. Great Puzzle!
I just love your delightful, jovial, quirky nature Simon. Every now and then I'll try to watch someone else solve something and as clever as they are they do tend to be a little.... flat in comparison. You're a gem
I really struggled with this, I had suspected that the rows or columns were going to have one of those hidden rules where each number had to be from 123, 456, and 789; but I couldn't find a good way to prove it so let it go... took me almost 2 hours to solve this, I almost wish I had just gone for, and played with that rule, would have solved it so quickly.
Heh, I spent 4 minutes frustratingly begging you to see the 6 in the top left box :P. Meanwhile you were finding plenty of other things I would have missed :).
59:18 ... I had a few false starts (I forgot that the 3-difference rule didn't cross box borders) but finally found my way to the end of this miracle-esque sudoku Nice puzzle!
Holy missed pencil marks Batman… I’m not real good at these, but this one was a little tough to watch lol. Sorry Simon still watched and gave a thumbs up. Still waaay better than I!
What a fun puzzle! Also, the first time I wound up with a completely different break-in from Simon! I worked out the two possible lines, and then starting playing around with possible patterns for the digits in box 7 (with the 3 in the corner!). I realized it was very hard to make an arrangement where the 1 and the 9 wouldn't break both lines. There was only one arrangement that only broke one of the lines, and I could find none that only broke the other. That quickly gave me all of box 7, which translated pretty quickly to boxes 1 and 9 because of their placed digits along the line. From there it was mostly sudoku with a few excursions into the orthogonal difference constraint.
These guys are incredible. I absolutely love the way he never tired of explaining the logic fully, every single time. These puzzles seem impossible, yet he makes them make sense! I even thought I might give it a go, but I can't even solve the first one on the app. Down to six cells with three digits between them, and both ways to arrange them seem equally valid with no conflicts 😢 Completely baffling to me. I guess I'll just stick to videos 😂 Keep up the great work, guys!
I don't know if the last few sudokus are more approachable, but I'm being able to complete almost all of them without looking at Simon's solutions :D As always, amazing video!
I was wondering when Simon will notice that a pencilmarked 6 cannot go next to a pencilmarked 5 in box 7. Obviously just some unknown time after noticing roping. :)
I really hope you guys ignore the "algorithm" and "analytics" and all that because I almost exclusively get Simon's sudoku videos in my feed (mostly from 3 years ago?) for some reason, but I enjoy both of your videos and I love the crosswords too!
That's one way of stopping Simon from singing, already put the three there ;-) Brilliant puzzle, the >3 logic (and its consequences) took a while to get used to but then it filled in beautifully
There is an easy trick that can be applied to all boxes after you have the 1 in box 7, and that is to consider which digit can be in the middle of each row pair in a box. From there on it is straightforward, and it all solves in a beautiful way.
At 33:15 another beautiful way of getting the 5 by row 3: 4 cannot go into r3c6 - r3c8 because there's only one digit left to go next with it. Following that the 6 can also not be in r3c6 - r3c8 because it can only go next to a 2 and a 9 and if it goes with a 9 there it would force the 4 into the wrong position. So r3c5 and r3c9 are a 4/6 pair, r3c6 and r3c8 are a 2/9 pair and r3c7 is a 5.
A few opportunities to shout at Simon today. I was particularly taken with trying to get across that 6 couldn't go next to 5, so was placeable in box 7 for quite some time. 🙂
This puzzle really irritated me, because I thought I was so clever trying to use low-mid-high coloring, which barely helped at all! Still a nice puzzle
Spoiler alert: Not only is there roping in the columns of the final grid, as Simon acknowledges, but there's also roping in the rows, even though it's not as dramatic.
The way you didn't see that the three couldn't go next to the one on the bottom is exactly how I see all digits at all times in all rulesets. Haha it's funny like that.
Once the ground work is in place, you just go through one digit at a time. "Where are all the threes? They must be here. Okay, where are all the fours?" Every digit could be finished or nearly finished before moving to the next one
56:10, had to undo after being confused, looking at the video, being even more confused, then rereading the rules to see that the "difference of 3" rule ONLY applies within boxes.
I enjoy this kind of solve. Where your 30 minutes in, have 20 digits and a hundred pencil marks. Then you hit a tipping point and the whole thing solves in three minutes.
at 30:45, if it's a 5, the neiboring digit is than an 8 and the 6 is placed above the 3. You can apply the rules to set the 4 away from the six and the 2 finally has no place in the box proving it imposible.
I would love to watch you guys play The Last Express...murder mystery type game on the orient express, thought to be one of the best games in its genre. It uses stop motion graphics so you won't get the nauseous effect like some games. The special thing about it is that it uses a real time game mechanic. I played it multiple times years ago when it first came out and I just bought it again on Steam since it is on sale to play again!
Can someone explain what's the story behind the number 3 in the corner? And the saying, 'That's 3 in the corner, 3 in the spotlight, losing its religion' ? Thanks in advance.
@@arutsudar it’s based on song from the 90s by R.E.M. that goes, “ that’s me in the corner, that’s me in the spotlight, losing my religion.” So it is a play on words from that.
Other people have explained the reference but on the channel its a running trope because one time, i wanna say on a phisto puzzle but i dont recall exactly, Simon got a 3 in a corner of the puzzle and while trying to figure out what to do next decided to sing the song only replacing Me for Three. Then people started commenting about it anytime it appeared in another puzzle. Then Sven put an animation into the software whenever a non given 3 is put into one of the four corners of the grid. And now its taken on a life of its own and become almost a theme of the channel.
Adding to what others have commented, many setters have integrated into their puzzles that a 3 is needed in one of the corners. Sort of an Easter egg for Simon and Mark.
"I need to remember to use the difference rule.", use it once to get one digit in a box that the rule can complete, move on to a different box instead....repeat repeat
I got 45 minutes in and broke the puzzle in box 4, so I'll have to have another go at it later. EDIT: restarted entirely and finished with a total time of 90 minutes.
