zetamath sets a sudoku puzzle LIVE

[@josephnehme7224]

I enjoyed seeing your setting process. I recommend adding 3 givens for the next one with one being a lie. It was incredibly fun to set when i used it in my puzzle.

[@zetamath]

I did consider that actually, for both this puzzle and the original two truths and a lie. I figured out that I could unobtrusively put them in as one cell killer cages. But then I just didn't use the idea. It will have to wait until version 3 I suppose (-:

This was absolutely enthralling to watch, thank you so much for sharing it! I theoretically had other stuff I was meant to do this evening (boring life admin things), but got COMPLETELY sucked in and it's now a quarter past midnight, my goodness! I really enjoyed the solve too, which I attempted earlier today - favourite bits of logic were the initial break-in, and the use of the wrong 23, in my case well over an hour after figuring out that it WAS wrong, made me smile! Did mess up a couple of times (notably by failing to include 1238 = 14 as a possibility for the little killer!) but Simon set me right... Was very proud of myself for solving Two Truths And A Lie by myself, over the course of three evenings. Once again: bravo, and I look forward to more rule-breaking metapuzzles like these :)

Thank you so much for the kind words, I'm glad this little experiment worked out well for you!

[@willemkossen]

Thanks for sharing. It took multiple days to watch the video, but i gladly did. I tried setting puzzles before. Your process makes me want to try again.

[@zetamathdoespuzzles]

You should do it, with some practice and grit anyone can!

[@afrayedknot81]

10:08 "okay let me try and make sure I understand the logic of this puzzle here" I actually lol'd because it's hilarious to think you're trying to understand logic you're creating. At the same time, I realized I've done the same thing dozens of times while setting.

Reminds me of the quote from Michelangelo "Every block of stone has a statue inside it and it is the task of the sculptor to discover it" Every Grid has a Sudoku inside it and it is the task of the setter to discover it

[@jorava8768]

This was very illuminating. I loved seeing the process. It's interesting how similar the process was to the actual solving of the sudoku.

[@Ibuiltatower]

A really great look behind the curtain, both for a solver and a setter! Thank you so much for making this!

[@elainedenning]

This was fascinating to watch. The best setter video I've seen to date, so thanks!

[@zetamath]

Thank you so much, I'm glad it made for good viewing!

[@alvaropallete]

Really interesting to see that you only started with the logic of row 9 and then see the process of the whole grid. It's also cool how sometimes clues just casually fit very well, for example box 1 with both 12 cages. Everything is easy to comprehend as always, great video!

[@IguitarVreakI]

Thank you for this. Very entertaining to watch. since I stumbled upon Cracking the Cryptic I've been thinking about setting but never had an idea how that would even look. Very enlightening video.

[@Tekay37]

I've only watched 22 minutes minutes yet but this video already gave me some good insight in how to construct a susoku puzzle and how introduce my own logical steps into it. Looking forward to watching the rest this evening.

[@bruresende]

Unfortunately, I had to break the video into several parts but finally did it... I enjoyed every minute... Thank you so much for sharing your process, it was really fascinating to watch!

[@zetamathdoespuzzles]

Thank you for the kind words, I'm gald you enjoyed it!

[@DJV512]

Ive been watching CTC for over 2 years now and have been wanting to see exactly this video for a while now. Glad I found it! Thank you for sharing your process!

[@zetamathdoespuzzles]

I'm happy to hear that! I also have a video like this one on the channel for the puzzle MIA, so if you enjoy this, there is another one like it!

[@DJV512]

@@zetamathdoespuzzles I will definitely check that out, thanks!

[@joeshonk9715]

Great explanation on how to create a puzzle. At t 55:04 wouldn't the question be "Where am I going to place the 789?" 3 digits in 2 spaces.

[@AshEshyr]

super to watch, looks like the 30 clues were moved in the final version and I assume thats just to make the logic at the end a little cleaner? either way this was fun to see

[@zetamath]

Yes, I had this plan to make the 23 cage resolve the deadly pattern, which it does, but in this placement of the 30 LK it actually cuts through the deadly pattern and resolves it. I was super lucky that I was able to move it without disrupting anything else!

[@elliottmanley5182]

I was gripped for the whole vid.

[@zetamathdoespuzzles]

I'm very glad you enjoyed it!

[@maxcalderon7815]

I really really enjoyed watching this,, and i’m glad it came up in my recommended videos!

[@Stephen-Fox]

Extremely useful video - I think both full documentation (like this) and summaries of the process (like most setter videos) are useful, but due to the nature of puzzle setting this sort of video is going to be much harder to make - Similar to how weekly dev blogs (or internal documentation) is always going to create a differently useful look at the process than an hour-long talk about how a video game was made.

[@humanbirdsong]

This is an enjoyable and valuable insight. Thank you!

[@notdetails]

This was fascinating, thank you!

[@brianbrown8481]

I want to see more of this

[@lizzyvv447]

So I wrote an entire comment, and youtube somehow managed to automatically delete it. So here it is again. In my solve instead of going through the entire logic with one of the 12 cages having to be 123, I immediatly noticed as soon as the 11 and 23 along the top are right, the 12 along the top is wrong, because 11 + 12 + 23 = 46 so if they where all right the 3 cells sticking out of row 1 would sum up to 1 which is impossible. Also, as you said you like the - where does this digit go in this other box - type logic, I think you might like my two latest puzzles, 'Four lockout lines' and 'Cycle'. Their puzzle id's on LMG are 0007J7 and 00083C. They have some other interesting tricks as well. I would love to know what you think of them!

[@orrvaa]

Thanks for the video was very instructive

[@nataliem4434]

really cool thx for sharing

[@primeprover]

A nice idea might be have 3 types of clues with one type being wrong. Alternatively three types of clues where picking 2 out of 3 clue types gives a different puzzle.

Novice Setter Question: How do you go from FPuzzles to CTC?

[@zetamathdoespuzzles]

Hi there! It's easy to do but too much to explain in a KZbin comment. Come chat with us on Discord, link in the video description, and we'll be happy to help out!

[@TheMeanAdmin]

Cat falling off a counter would get more likes, but this one will stay alive in more brains 'till tomorrow

[@57thorns]

I would hope I won't make the solver solve a system of linear equations. Right, someone will see that statement as a challenge. Also; very nice to see some behind the curtains.

[@57thorns]

I laughed at the comment at 57:05, Simon did the exact same thing. It was not just relevant until this point.

[@zetamathdoespuzzles]

@@57thorns I have solved multiple puzzles where I've had to solve a system of linear equations, but despite being a mathematician, I hope not to inflict that upon others. And yes, the fact that Simon also missed the given 5 looking at that cage for so long made me smile!
