- ** 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.crackingthecryptic.com/su...
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!
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
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.
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 :)
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
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.
I'd guess why it was called Mozzarella, but it would be a bit of a string theory.
25:48
That 5 was ready to be placed at 17:34 by SUDOKU. You're killing me Simon!
At 28:06 Simon penciled a 234 in the top row when the only filled in digit in the top row was a 2. He didn't notice till 32:44.
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.

Q2: Can you do this for another channel?
A2: I've been thinking about that and wrote some code to make that possible. Let me know which channel you think would be a good fit!
Thanks bot!
You are doing gods work!
I miss "Come on, brain !" :)
19:12 finish. Love this ruleset! The logic flowed quite nicely for me, without handing me anything. Excellent!
43:55 for me. That puzzle was crazy fun! My favorite part was figuring out a certain line *wasn't* 9 cells long.
I think the "evil clown" in box 3 is actually a little stick man doing a flying kick towards box 2.
25:05 for me. Loved the logic that Simon overlooked regarding boxes 3 and 9.
You can get even earlier on that the black dot in box 9 cannot be a 3-6 pair because of the renban line connecting boxes 3 and 9.
IE if the black dot is a 3-6, then R2C8 and R8C8 must be the same.
This also applies later into the puzzle when you know the 3-4-6 is on the bottom row. 4 must be R9C8 for the same reason.
39:06 for me. That was a very enjoyable puzzle. I didn’t need help from Simon. I stayed ahead the whole time. 😊
23:47
Mind-bending and grid-bending. Loved it!
I never tire of the guitar
The Phistomefel hunt is a delight - have not finished yet, and hope I will get it done tomorrow (otherwise it will be after Christmas) ... the final puzzle is something else, I think I have some (second phase) logic (if I am wrong, I will cry - it was the only thing I could think of to look at) ... the earlier puzzles get trickier as you go on, but the first couple are not hugely difficult - as with every Phistomefel there is insight required. Phistomefel knows how to set a challenging version of accessible, as well as a miraculous puzzle.
I'm enjoying it too, sort of. It took me 15 minutes to do the *example* for the first one, never mind the actual puzzle. And then the second one is a snake. A snake! My mind just hasn't learned to see snakes. But it will be a good activity for my winter break.😺
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.
This puzzle was a ton of fun. I definitely appreciated how the logic slowly revealed which lines were forced to be connected. Great new rule with a fun implementation.
18:53 for me. Somehow everything fell very smoothly into place without it being too easy. Thank you for sharing!
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. 😉
Great puzzle! Enjoyed that rule. Hope to see it again.
The toilet puzzles reminded me that on mine university we have toilets that play classical music when you start doing the deed. Might have been some student project but i find that amazing that it exists
Been an exceptional year Simon!! Can't thank you enough for all the amazing solves this channel has produced over the past 11 and half months.
Wishing you, Mark and family a wonderful, healthy and happy Christmas, holiday weekend.
Ditto!
@@longwaytotipperary One of my favorite responses from you. 😀
@@davidrattner9 Your response to Simon was perfection!
@longwaytotipperary always thank you my friend and wish you and family/friends a wonderful joyous happy Christmas holiday weekend!!
Can't belive 2022 is coming to end.
Bring on 2033 and more of this amazing community!!
@@davidrattner9 I wish the same for you and your family/friends/ loved ones! It’s soooo cold here. Stay warm!
i absolutely love your channel, it is so calming and intriguing. have a great holiday and keep up the good work! ❤️
Super cool puzzle. I love how intuitively it fit together.
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!
This was a delightful puzzle!
Enjoyable and not too strenuous pre-Xmas mental workout, thanks.
Very fun - a great video and solve for a great puzzle. Thank you, Simon! (The festive hat these past few days lends a very nice air to the season!)
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!
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
Interesting ruleset, thank you for the puzzle 🙏
Loved the matrix glitch. Puzzle solving of 53:11 minutes in a 46:25 CTC video. Might be because of The Torus 🤣
Simon commented on the smiling clown in the upper right, while my eye was drawn to the scowling one in the lower left!
Nice to see someone else from Curitiba!
we are the best city in Brazil, you should visit
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
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
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 love that every video Simon complains about the colors that he put in the palette.
That was a very clever puzzle.
Wow one of my favorites! Tough but everything fell together really well. Didnt refer back to the video!
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
Wow. At first the rule set seemed silly but this was a great puzzle and idea!
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!
I love your Windows-app that I bought (for almost nothing)! Please do some easier Sudoku like this one. I can do this almost without any help! Most of them are too hard for me, but I'm learning fast!
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
17:42 you can also remove 3 and 6 from r8c7 because if you put one of them there the other still needs to appear on the Renban line and no matter where you put it it sees r8c8 giving r8c8 no fill that works with the dot. So r8c7 is a 2.
Lovely puzzle, a good level of difficulty when trying a new ruleset
17:42 just felt like I got a stroke of genius and I need to share it
r8c7 has to be a 2, because if it was a 3 or a 6, the other side of the black dot has to be the other 3 or 6. And since both of them looks at r2c8, whose only option is 3 and 6, it wouldn't work.
I know not everything is a competition, but I think I actually completed this one faster than Simon (27:30). This might just be my greatest sudoku solving accomplishment ever! In all seriousness, this was a hugely fun puzzle!
Very nice!
17:00 exactly for me. A very clever idea. I suppose the same idea could work well for palindrome lines.
My father from Liverpool would say, "Yey, Congrats!" as your program does, but here in the states we say, "Yay." I hadn't noticed that before...
Didn't you miss some beautiful logic when the black dot in box 9 would put the same digit on the line if it was a 36 domino?
Or duplicate a digit in the column
One day simon will learn that dark colors lead to "garish" clashes. Just code them to lighter shades!
Ha! I'm here on time for once! Let's get cracking
33:41 Very clever puzzle, and not nearly as hard as I was anticipating. A lot of fun.
I absolutely loved this puzzle! Managed it in 31:11 ^_^
22:39 for me, though I felt I had a bit of a slow start before things really starting sinking in. Very cool alteration on the renban constraint!
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.
The kropki pairs immediately struck me as the place to start.
I think it's called Mozzarella because Mozzarella also comes in a kind of doughnut/torus shape.
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!
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.
38:17 and I'm damn pleased by it.
Why is is called Mozarella? When the moon hits your eye like a big pizza pie, that's Sudoku!
Mozart+Cinderella
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.
22:36 ... and now we wait for this ruleset to combo with German Whispers, Entropy, Thermo, Palindrome, ... oh geez!
Nice puzzle!
2.5 years ago you did a spiral galaxy sudoku by Bismuth where the galaxies wrapped around to the other side.
I want to see the bad jokes next to the Phistomefel Ring proof!
Don't eat the white mint?
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.
Being new to this puzzle type I keep trying to review options using standard sudoku rules but this is one of those puzzles where even when near completion you still can't disambiguate without coming back to the custom rules.
88:33 was my final time here. Nothing particularly impressive lol, but I did restart twice and wasted 10 min in the middle... Regardless, this was an excellent puzzle! I did a terrible job managing the wrapping element at first, but it ended up as an exceptionally intuitive rule once everything clicked. Spoilers below.
Spoilers:
It took me quite a while to wrap my head around the cycling across edges concept, or more specifically, I shot myself in the foot by not mapping out all the possible connections in advance. My two restarts came from overlooking the possibility of R9C2 and R1C2 connecting, so the kropke dot combination "broke" the 2 cell renban in Box 7... I wish I remembered all the steps after that breakthrough lol, but that's the danger of early morning solves. I do recall that once the last big deduction occurred (figuring out that R4C9 and R4C1 didn't connect), the ending flowed incredibly smoothly even for an amateur like myself, which is quite the feat :)
Waiting for the RP^2 sudoku now :)
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.
27:24 for me including a few interruptions. Enjoyed this one.
A little over two hours of concentration and confusion... but I still solved it with great pleasure. An interesting version of the purple lines.
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.
Poor Red: "Put me in, coach! I'm right here!!"
Did it in 29:23, really intuitive puzzle 🫶🏻
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! 😁😁
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!
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.
39 minutes. Nice logic flow, solid path, easy but not too easy. it's in the goldilocks zone for sure. Thanks!
In my solve I solved the black dot in R8C7/8 before I looked at the purple line in R8C1/2 and solved it with a rather pretty piece of logic. Since the digits cannot repeat on the purple lines, you can think about whether R8C7 can ever be a 3. If that is a 3, R2C8 has to be a 6, therefore the other side of the black dot in R8C8 cannot be a 6 anymore and it's broken. The same is if you try to put 6 into R8C7. So you can rule out 3 and 6 from the black dot, leaving you with a 2 in R8C7 and a 1/4 in R8C8. After that I did the logic with the purple line in R8C1/2, which then helped solve the 1/4
