One Of The Most Beautiful Sudoku Grids Ever

[@Shoodowop]

Thank you so so so much for the feature, Simon. I am ABSOLUTELY FLOORED by the title of this video. I cannot wait to watch your solve; I will comment my thoughts afterwards. Woohoo!

[@Shoodowop]

This channel has been such a huge part of my life since Covid. I started making puzzles this past summer and to see you and Mark solve them on the channel is a dream come true. I am a high school math teacher in NY and you can bet one of the first things I did was send my students the link! I am getting many emails already from them saying they commented 😂 *Just finished watching. I am so glad you liked it Simon, I will be bragging about this forever!

@@Shoodowop It was wonderful! Thank you. ^_^

[@gi0nbecell]

Wonderful puzzle. Haven‘t watched the video yet, but the way things unravelled in my solve, causing unexpected roping and disjointed pairs was really pretty. I‘m not entirely sure I followed the intended path, but I enjoyed it nonetheless. Took me around 70 minutes to solve though (well, I‘m a bit tired, it‘s been nearly 1am in Germany when I started, so that might excuse it). Your students can really be happy to have a teacher like you, who obviously possesses the rare talent to create more than just plain syllabus - I had two of this sort in my time, both of whom I hold dear to this day (I graduated with Abitur in 2008 - it‘s a bit hard to locate to the US system, Abitur is somewhat more than a high school diploma, but not entirely comparable to an undergraduate). One has started my connection to the English language when I was only about 10 (5th grade in Germany), the other was the best maths and economics teacher (and all around the best pedagogues ever had). Good teachers are a blessing (as well as bad ones can cause life-long disconnection from their respective subject - for instance, I still can‘t really connect to classic German literature, as strange as that may seem). In short: Thank you.

Mr.Napolitano is one of the best math teachers I’ve had. He makes sure all his students understand the topics by taking the time to help when needed. He is such a fun teacher and he is really involved with his students.

[@NiaReid-x5w]

Wow… what an awesome creation by my Algebra 2 teacher Mr.Napolitano. This is not shocking due to my teacher being one of the smartest math teachers I’ve come across throughout my school years. Keep up the good work Mr.Nap😀

Mr.Nap is my Algebra2/Trig teacher. He is an amazing teacher and is funny. He is patient when it comes to explaining tough concepts.

Mr. Napolitano is my Algebra 2 teacher, he is amazing. He has patience with our class even when we are talking non stop. He makes sure we all understand the lessons and offers test corrections if we score low on a test. I am very grateful for Mr. Napolitano.

[@David_K_Booth]

Lovely to see the positive comments from his students. Fifty years ago, an algebra teacher mentioned the Fermat two-square theorem to me, and it was probably the moment that led to my studying math[s] rather than modern languages at university, and ultimately a rewarding career as a freelance software developer. Thank you, inspiring teachers everywhere.

[@chocolateboy300]

I finished in 42:55 minutes. This was an absolutely beautiful puzzle. The way the negative constraint worked was so pleasing. I think my favorite part was seeing that the 23 pair that flanks either side of 678, such as in box 7, always had to have a 6 between them. That was my favorite part until I started coloring the 23 pairs and the 78 pairs and started playing keep away using the X rule. That was so satisfying to do. This has to be one of my favorites. Great Puzzle!

[@ryanrinaldo9147]

I actually thought "I wonder if the negative diagonal counts as a renban since it is purple", and then I decided, yes it certainly does, but so does the positive diagonal.

[@Kagoolie]

I'm proud to say it took me 38:20 though I fully admit there was a lot I missed without the helping hand of Simon's guidance and humour through the journey. Absolutely loved this brain melter and hopefully I've learned a few things and my extreme joy of colouring puzzles aren't for naught

[@davidhughes7174]

Another beautiful puzzle, solved with grace and charm. Thank you Simon.

[@jamese4336]

At 24:00 the deduction I found that made it easier was that the V in box 5 was a 0/5 pair. The 0/5 pairs in boxes 7 and 9 are off the negative diagonals. This means that there must be a 0 or a 5 on both of the negative diagonals in box 5 and the only way that can happen is if the V in box 5 is a 0/5 pair.

[@Bweigelt13]

Yeah I finished in 28:37 and had the same deduction.

[@matthiasney4871]

Yes. Would have saved a lot of complex coloring, that's why Simon found this puzzle quite difficult while according to the ratings most people (including me) didn't. When you just ask for the placements of the 0/5, 1/4 and 2/3-pairs, it is pretty straightforward. I used two colors (0-5, 678), and when I found the symmetry of the 0/5-pairs, added a third, and could easily run through the entire puzzle.

[@jonh6585]

Yes. I also coloured the 78 to realise that the 14 or 23 in r6c6 was seeing same 78 as the other 23 on the negative diagonal so that's impossible so it must be a 14

[@paula-zzz]

all of these comments from his students talking positively about him are so cute :)

[@RedBarchetta2019]

I much more enjoyed the "pencilMARK" approach. Pencil ALL the vertical roping in ALL the columns. Pretty easy to see. Then look at the third and fourth digits on the negative diagonal - is a 78 pair. So 2-3 is gone from the touching neighbors. Then 6 can't go with 4; use neg. constraint, etc etc. This flowed very well, great puzzle, Nap!

Loved it because I saw all the roping coming fast and just took more time than needed because I didn't appreciate the consequences of the negative constraint. The absence of V-pairs in box 7.

[@David_K_Booth]

A very nice puzzle, and it was interesting that my use of colour was quite different from Simon's. Evidently there's more than one way to approach it.

[@iuriikononenko9238]

Great puzzle! Exactly what I like about searching for a right place for a right digit. For me central V worked out from 05 being out of both diagonals in boxes 7 and 9, thus each diagonal would need a 05 digit from central box, and this could be done only from central one being 05.

[@DestroyerofX]

At 33:00 could you have figured out red because of the diagonal red/black square being pencil marked as 6/8? Since you already knew black was 6 I think that would’ve meant red was 8

[@tomasvdw9173]

I don't think that that deduction is correct and it seems to be an interesting pitfall of the coloring method. The constraints at this point are: - The r3c7 cell is either the black or the red digit. - The r3c7 cell is either a 6 or an 8. - The black cells are 6 and the red cells are either 7 or 8. It can still be that red is 7 because this doesn't at this point create any contradictions; all statements can still be true. Hence we cannot conclude that red is 8.

[@davidethelberg2091]

Mild spoiler: I thought that too, but in the end it turned out that red was 7, but I dont see why the login doesn't work

[@RichSmith77]

​@@davidethelberg2091Doesn't work because r6c4 can still be 7 (and red).
