- ** THE SUDOKU EVENT OF THE YEAR **
Huge news: Phistomefel's first ever sudoku hunt is OUT!!! We've gifted it as a Christmas present to all our patrons to say "Thank you" for supporting us.

** TODAY'S PUZZLE **
An absolutely fabulous novel idea today from the constructor Perladel - in which purple lines can reappear on the other side of the grid! It's called Mozzarella and we think this ruleset has legs. Only 2/5 on the difficulty scale so do try and have a go at it if you have time.
Play it at the link below:
app.crackingth...
Rules:
Normal sudoku rules apply. Cells separated by black dot must contain digits in a 1:2 ratio (ie one digit will be double the other). Purple lines must contain a set of consecutive non-repeating digits; however lines that have endpoints on the edges of the grid might wrap around ORTHOGONALLY and continue on the other side (through the endpoints). Eg r9c6 could join to the line in r1c6 thereby creating a 6-cell purple line (or it might not!). Solvers must determine which lines wrap around.
** NEW CONTENT ON PATREON **
As well as the incoming Phistomefel extravaganza, Simon's solve of tallcat's Shadow is now available - if you want to try the puzzle (which is a mind-melter) then check it out at this link:

Thanks a lot for the feature! "Steamed Hams" was actually an anomaly, I'm happier when people enjoy my easier puzzles :)
I'd say that the name "Mozzarella" refers to some private life routine: whenever we order a pizza, my sister generally asks for extra mozzarella and that mozzarella "never respects its borders" and always overflows ("polluting" mine or other family members' pizzas).
And the renban lines of this puzzle "overflow" outside the grid as well
I'd say it's fair that Simon couldn't figure the name out, then ;-)
@@frankwales
You'd be correct :P
@@frankwales
Who cares if it's fair, Simon'll ramble in ten different directions, lol.
;)) 😂😎☕️
Thanks for the fun puzzle!
@@wanderlustwarrior you're welcome!
Completed the puzzle in 2:02:00
I've been trying the "easier" ones (i.e. those with a video length of less than hour) and this is one of the first I've solved! Obviously won't be winning any races, but hey at least I did it, right?
Well done! The first solve is always special, _and now you're hooked_ :D
if i had a penny for every time simon referred to the color blue as garish in this video, i would have 3 of them, which isnt much, but it’s amusing that it has happened more than once
It isn't as though he's only got the one blue in the palette 🎨 there are 6 different shades of blue, some which _(shock horror!)_ actually allow you to read digits pencil marked onto them!
I think he might be a little colour blind, he always uses pink and calls it purple. It's nowhere close to being purple!
19:50 That kropki can't be 36 because it sees "the other" 36 in the same column, because of the toroidal renban
Yes! I was so disappointed when he didn't see that logic and instead found another resoundingly longer route to it 😂
28:22 Simon laments not being able to restrict the 12468 pencil mark with a 234 triple breathing down his neck.
I'd guess why it was called Mozzarella, but it would be a bit of a string theory.
Finally, a sudoku that could be continuously deformed in to a coffee mug!
Lol. Would be an awesome idea.
Found the topologist
I like to drink out of Klein bottles.
How would you pour the coffee in?
Make an actual coffee mug with a deformed version of the puzzle
23:16
A small deduction: if you put either 3 or 6 in R8C7, that would create a 3/6 pair with R2C8, which would mean you can put neither 3 nor 6 on the black dot in R8C8
With all the new coloring features in the app, I think a couple of puzzles ago Simon changed the shade of the standard blue to be a bit darker. This now results in his once favorite colour blue to be gerish over and over again :)
At 23:19 Simon found that r8c7 was a 2. I was really hoping he would have found it as soon as he worked out what the yellow renban line was.
Due to the connected nature of r8c7 and r2c8 you can never put 3 or 6 on the black dot in row 8. If you tried to make r8c7 3, then r2c8 would become a 6 ruling itself out of r8c8 and breaking the black dot.
This was the first time I felt what I think Simon feels when he describes logic as beautiful and I really wanted him to see it as well.
That is particularly elegant. I didn't see it either (which is less surprising) and did it the exact way that Simon did. In fact I pretty well followed his logic although not always in the same order (including hopping up and down wanting him to see the "5" logic that opens it up at the end). I'm really pleased to have solved this, but I'm not totally sure I really liked the variation. But I'd certainly give another one a go.
28:24 "I thought I was going to be able to restrict that in some way" you thought right (234 triple in box)
An early pretty piece of logic on the black dot in box 9: the left side of it (on the renban) can't be 3 or 6 because its kropki counterpart sees the opposing 36 in R2C8.
Cracking the Cryptic shows
Perladel‘s aptitude
Adding continued lines

No worries: we could always pretend it's a pass for a touchdown in American football!
19:12 finish. Love this ruleset! The logic flowed quite nicely for me, without handing me anything. Excellent!
I never tire of the guitar
39:06 for me. That was a very enjoyable puzzle. I didn’t need help from Simon. I stayed ahead the whole time. 😊
I think the "evil clown" in box 3 is actually a little stick man doing a flying kick towards box 2.

Thanks bot!
You are doing gods work!
I miss "Come on, brain !" :)
Man, I feel proud that I got through the logic part of this puzzle waaay faster than Mark did, but Mark still beat my time cuz I took forever and a half to scan and finish it off.
I love that every video Simon complains about the colors that he put in the palette.
That was a really interesting rule, thank you Perladel 👍🏻
It took me 40 minutes, which is about the same as Simon's solve time, so I'm very happy with that.
It's not necessarily the same time as video length. He talks and explains a lot. I usually calculate as 2/3 of the video length.
I'm glad you enjoyed it :D
What a nice puzzle! I really enjoyed solving it, it had many super interesting turns and twists for me. :)
And a small point about Portuguese pronounciation: if her name is spelled "Giulia", it's either pronounced as (English) "Julia" or with a soft J (as the _s_ in "pleasure", or as a regular J in French). And the city is pronounced "koo-ree-TEE-bah" (or "-TCHEE-bah", as accents vary).
All of which, of course, you are 100% expected to know without cause or justification, and if you don't I'm going to make sudoku rows add up to 42. 😉
Enjoyable and not too strenuous pre-Xmas mental workout, thanks.
18:53 for me. Somehow everything fell very smoothly into place without it being too easy. Thank you for sharing!
sudoku starts at 6:10
This is the first puzzle I've solved catching up after the Phistomefel hunt and I've got to say, it sure seemed super easy after that amazing adventure!
An utter blessing of a puzzle in a blessing of a run of puzzles! Love this new ruleset, more toroidal renbans please! Such beautiful logic in several moments, clever eliminations and such. Well set and well solved! Nice musical intro as well! I think the title is Mozzarella because the renbans stretch around the back side like a melty/stringy cheese maybe
Nice to see someone else from Curitiba!
we are the best city in Brazil, you should visit
i absolutely love your channel, it is so calming and intriguing. have a great holiday and keep up the good work! ❤️
So amusing to watch. Really like how Simon always keeps you thinking there could be a tough bit left when he starts to crush the puzzle.
You should print different puzzles on coaster's. CTC logo on one side. Merry Christmas
I’ve spent the whole of Xmas binging sudoku videos - I haven’t watched any since like lockdown, and I did this in 25:13 with a bit of guidance from this video so the time watching these videos was definitely well spent
Simon commented on the smiling clown in the upper right, while my eye was drawn to the scowling one in the lower left!
I think it's called Mozzarella because Mozzarella also comes in a kind of doughnut/torus shape.
22:03 This one threw me for a loop at first (pun very much intended), had to restart and come back to it to get my bearings but I'm happy I did
12:14 for me. What a fantastic ruleset!! I had seen some similar ideas before, but never combined with renban lines like this. Loved it!
Loved the matrix glitch. Puzzle solving of 53:11 minutes in a 46:25 CTC video. Might be because of The Torus 🤣
Got it in 29:33 ! At first this seemed like a rule set i couldnt wrap my head around but the 'wrapping around' actually became quite clear very quickly
I finished in 69 minutes. This was a fun ruleset to figure out. I seem to like these puzzles that have rules that need you to calculate two possibilities at once, either it exists as is or does it connect across the grid. I'm very happy with my logic performed, finding some neat tricks. Great Puzzle!
Wow one of my favorites! Tough but everything fell together really well. Didnt refer back to the video!
I absolutely loved this puzzle! Managed it in 31:11 ^_^
Finished it in 82:21. I don't think I did very well at scanning, but I liked figuring out which renbans flowed over to the other side.
This was a delightful puzzle!
38:17 and I'm damn pleased by it.
Wow. At first the rule set seemed silly but this was a great puzzle and idea!
27:12 for me. Figured out where to start this puzzle almost immediately and the rest felt a little bit like it magically solved itself.
Loved this one. Worked on it for 16 minutes, realized I had IMMEDIATELY made an error in logic in r2c9, then restarted and finished in 31 minutes! Well, I suppose I finished in 47 minutes technically, but who's counting.
2.5 years ago you did a spiral galaxy sudoku by Bismuth where the galaxies wrapped around to the other side.
The kropki pairs immediately struck me as the place to start.
17:00 exactly for me. A very clever idea. I suppose the same idea could work well for palindrome lines.
Cool new rule that will do wonders in future sudokus. This one was a bit on the easy side. Isnt often that I can see most solutions before you call them out.

Absolutely wonderful with 2 limericks today!! 😃
33:41 Very clever puzzle, and not nearly as hard as I was anticipating. A lot of fun.
How did I ended up for watching them solving Sudokus the whole day and am now early to a Video?
It's odd but I like it!
22:36 ... and now we wait for this ruleset to combo with German Whispers, Entropy, Thermo, Palindrome, ... oh geez!
Nice puzzle!
Great puzzle! Enjoyed that rule. Hope to see it again.
25:45 for me. What a strange rule, especially the part where you have to figure out which ones loops around and which ones don't.
A little over two hours of concentration and confusion... but I still solved it with great pleasure. An interesting version of the purple lines.
17:30 at this point, we can place 5 in r7c7 and 2 in r8c7, and this also means we can place 1 in r8c8 (because 4 makes the renban in box 7 impossible).
Very nice!
Interesting ruleset, thank you for the puzzle 🙏
Poor Red: "Put me in, coach! I'm right here!!"
Lots of shouting at the screen tonight. Maybe it's the energy drink I've just downed, but my brain is not just keeping up with Simon, but a couple of minutes ahead for a change!
I'm pretty sure I tested this puzzle! Partially because I also came up with this ruleset, independently, and set my one and only puzzle (so far) based on it. This one is better though; my rules were much more complicated.
Ha! I'm here on time for once! Let's get cracking
27min 17sec for me. I like this ruleset
29:45 for me. The length of the video almost put me off trying but I'm glad it didn't! The 2/5 difficulty rating pulled me back in.
For all of you in the comments finishing puzzles like these in 15 or 20 or 25 minutes, do you have any advice on how to continually get better? Like is it just a lot of practice and puzzles, or do you actually do something beyond this to get efficient and quick?
A lot of it is skill, but natural talent doesn't hurt! When I am stuck on a bit of logic in a puzzle I pull up my UA-cam app and look for a good CTC episode that features the logic. My personal preference is Simon's videos. He seems to me to be more willing to share his logic as he goes, where as Mark is a speed runner. Don't get me wrong, I do enjoy Mark's videos, but I like them for completely different reasons than Simon's.
Anyway.... I haven't been brave enough to try setting a puzzle yet, but I imagine that would help as well. I also remember Simon saying a few times that his knowledge of triangular numbers (ex. 1+2+3=6) is quite helpful.
Hope my rambling helps!
@@MrDon4343 Yes! That has definitely helped me as well! I love the GAS pack!
39 minutes. Nice logic flow, solid path, easy but not too easy. it's in the goldilocks zone for sure. Thanks!
I must have been so lucky in where I looked next because 16:34 when I was on the fence about trying it in the first place due to the video length's correlation with difficulty.
That was.... interesting! But quite enjoyable. Of course, I did take somewhat longer than Simon! 😁😁
Waiting for the RP^2 sudoku now :)
Just a tiny bit disappointed that Simon didn’t use the pen tool to draw the renban lines off the grid.
That was rather good. I did mess up my first attempt but completed it second time round in 50:32. Not quite as hard as I expected actually.
At 37:49, the 5s in boxes 5 and 9 force a 5 onto the renban in box 6. The renban in box 4 already has a 5, therefore the two lines are separate, and the one in box 6 is 2,3,4,5.
Edit: and as usual, Simon spots it about 2 minutes after I comment!! 😁😁
That 5 pencil mark was available even before finding the 5 in box 3.
About ten minutes Simon missed that.
I was relieved to find that the renban sequences themselves cannot be toroidally connected. That is, 8912 cannot be on a renban line, although it could if 1-to-9 looped over with the 1 and 9 being neighbors. If so, the puzzle would seem to get much harder.
Nowadays, it is quite common for you to say that there is no thing as a Schrödinger cell in sudoku. Well, careful what you wish for. someone may or may not create a Schrödinger sudoku with doublers and halvers.. .
There has already been at least one puzzle with Schrödinger cells that simultaneously had two values 🤪
I have already seen that. That's why I added additional conditions. Btw, I've seen the video in which he wished for halvers and the 2 videos that preceeded it.
Jay Dyer will be on to it and perhaps also Scruffamudda (see LMD for stunning modifier puzzles from both). There was a suggestion the other day that Jay Dyer would be constructing a puzzle hunt - these are dangerous ideas ... the last Phistomefel puzzle from the hunt is hard enough - surely?
Should have purplified the last 2 lines once you knew they were unconnected.
Perhaps it's called Mozzarella because it turns your brain into string cheese 😆
I found the break in and got very far into this puzzle very very quickly. After just 10 or 15 min I was already further than Simon's position at 40:00 when he finally notices 5 is forced onto the line in box 6, but then I kept breaking the puzzle on the homestretch and backtracking over and over for a good 60 min!! I'm still not sure exactly what I kept messing up, but after a cracking start I wound up with a time of 78:04! 😆😆
38:09 for me
I can't believe that i am able to handle this puzzle
After i read the rules, i were thinking about giving it up
Fortunately i give a try before let it go
Feeling good right now😂
I would have solved this faster, but the purple lines makes the blue pencilmarks harder to spot. Anyway, I did it in 33:26.
You had 5 pencil marked in box 7 for ages but didnt use it at all in sorting out the line in box 9
@41:35 r3c1 can't be a 6 by Sudoku of all things, Simon lol
30:46 on this one, quite a fun solve. I don't do a lot of renban sudoku, and adding in the toroid... well, it's not a constraint, more of an anti-constraint, gave it quite a bit of complexity.
Hey seu curitibano, ou, curitáibano bchshs, finalmente um BR aqui
Cheio de BR, e curitibanos aqui.
I spent 27 minutes to fill all grid but broke the puzzle.
It takes me some time to find r7c9 is 79[I fill 7 directly and made a mistake]
52:38 to finish. nice puzzle.
Very good but some sudoku earlier on might have saved a bit of time.
32:09 for me. Interesting rule set!
17:40 can't be 6
Could r4 c1 and r4 c9 really have connected?? Because none of the endpoints were actually pointing to the edge of the grid, I just assumed they couldn’t conjoin with each other
Yeah the puzzle just requires the presence of the endpoints near an edge: the point is that you have to create a new renban line on a toroidal grid (with the additional constraint of orthogonality i.e. avoiding diagonal connections if you intersect the border).
You don't need the endpoints to point each other because even with normal renban lines you can always create a single one by joining them with an orthogonal connection
Ah…well that’s not how I interpreted it. I still managed to solve the puzzle in about 38 min….but if those renbans did wrap around, then I would’ve probably just restarted the whole puzzle and give up after getting the same results over and over
Ive made a few donut sudokus in my time - i didnt realise this wasnt a really common thing!
I dont understand why Simon uses pencilmarks. He never use them anyway
The software seems to be completely broken. I can select cells on the grid, but that’s all - can’t get numbers or use any tools.
16:15 for me. this was quite easy.
Why does r4c1 Not continue to r4c9? There are 2 fives on it. This is a mistake i think😅
Quite nice. ~25:21 for me,
I was looking for the bot that says all the time points and I didn't find it. What happend to it?
21:12 for me.
Hey Simon, is it just me or are there two solutions to this puzzle? Swapping around the 4 and 3 in row 7 as well as the 3 and 5 in column 8, then tidying up the rest gives me a valid solution as far as I (and the website) can tell.
Does your toroidal renban line between box 1 and box 7 have a 5 on it? (the blue one in Simon's solve)
If it doesn't, your solution should be wrong
@@mariorieti7409 It does have a 5 in my solve, it is the exact same as his. His green line is different from mine, where he has a 4 I have a 2.
Which I now see is where it's wrong.
52:21 for me
Made a mistake the first time, but got a 33:53 the second time around. Would this count as my first time beating Simon? =D
