- ** TODAY'S PUZZLE **
A terrifying prospect today in the form of the great zetamath teaming up with his friends to create a puzzle!! This means the combined IQ devoted to the construction of this sudoku will be prodigious - and it also means the sheer quality in play will be staggering. Don't watch the football - this is much more fun!

A colour-blind friendly version of the grid is also available at this link but you'll need the full version of the rules included below:
sudokupad.app/y697kc2umn
Rules:
Normal sudoku rules apply. Additionally, in this puzzle digits cannot repeat on a line. Digits along a grey line can be broken into non-overlapping segments whose digits sum to ten. Eg 71246 is a valid fill for a length 5 line, because it can be broken into 712 and 46, each of which sum to 10. Along a green line, adjacent digits must differ by at least 5. Along a blue line, the 3x3 box borders divide the line into segments; each segment’s digits have the same sum. (Different lines can have different sums.) eg r5c2+r4c2 = r3c2+r3c3+r2c3 = r2c4+r2c5+r2c6. The sum of the digits along a line connecting two circles is equal to the sum of the digits in the circles. In this puzzle, digits can't repeat in any of these five cells. Any three adjacent digits along a teal line must include one digit from 147, one from 258, and one from 369. Any three adjacent digits along a peach line must include one digit from 123, one from 456, and one from 789. Along red lines, each pair of adjacent digits must have one even and one odd digit.

What is this? extensive pencil-marking and removal of colors once they've served their purpose?! Mark, what have you done with Simon?
I'd just finished having a private moan that those colours would be staying until the very end of the puzzle, by which time every 8 would be coloured yellow, and so on, making the grid look a complete mess...
...and then he deleted them.
I think I may have actually applauded. 😂
One thing I appreciate about a zetamath puzzle, at least the sudoku, is that you can generally look to Box 1 for the break-in. Their goal is never to disguise their intention or their cleverness but rather to invite you along for the ride.
Simon definitely deserved to be the first to solve this. Almost seemed like it was made for him with the variety of logic. Even with the slight delay of putting in the last digit, impressive time of solve! Kind comment.
Thank you for decluttering the puzzle Simon.
Nooooo! I love the rainbow mess that emerges at the end of each puzzle!
Just love Simon saying "It's always Sudoku" and then when he's stuck always forgetting to do Sudoku!! :)
Thank you for the birthday wishes!! I've been quietly watching your videos lately -- sudoku is fascinating to me, and my friend must have found out that you share well wishes!! My 21st has been wild but good, and I'm ready to relax to this until I can finally sleep. Thank you again for a lovely surprise!
I am Dutch, and I have my priorities right. I prefer squares over balls
Me too
So do you prefer your line restrictions to be adjacent digits being at least 4 digits apart instead of 5?
@@TheDarkNerd they mean Sudoku > football.
@@TheDarkNerdI am not fussy, but draw the line at Chinese whispers. Never got that
So even numbers over odd ones it is?🤔🙃
One of Simon's advantages is he reads the rules to us before playing. I find my presumption about the rules (as opposed to reading of them) can often let me down. ;-)
Just as I was thinking that the colors no longer served their purpose, Simon removed them. Good decision :)
Great solve, loved it.
As a non-native english speaker I had to google "teal". After I got that one solved, it was really entertaining and challenging puzzle (75 minutes). Guaranteed Zetamath quality as always.
@7:30... when Simon claims that the 4 cell line in box 9 looks longer than the one in box 4/5... it's because it is longer... ~41% longer!
29:52
Half an hour of absolute magic. Thank you zetamath et al.
When I first started watching this chanel, I thought I was SO smart for spotting things that Simon didn't. Now I know that Simon only spots the really clever, brilliant pieces of logic, and yet frequently 'doses off' on the plain old sudoku parts. Absolutely adore following along ❤
25:20 A different route to directly resolve the placement of yellow in box 3 here: Whatever of 1 or 2 pairs with yellow to sum to 10 must go on the endpoint cell of the grey line adjacent to it. But the 14 sum in box 2 is going to have that same 1 or 2 (the part of that 14 sum that is not the 4 is after all itself a 10 sum including yellow). Therefore if r3c9 was yellow you'd need to repeat that 1 or 2 in row 2.
This puzzle kicked my ass. Had to check the video several times to figure out where I'd gone wrong. Even with that, took me 79 minutes.
I’ve been watching Simon solve sudoku for 4 hours I cant sleep it’s 4am someone stop me
STOP!!! SLEEP ALREADY!!!!! I KNOW HOW IT IS! HAHA.
Huh. Usually people watch Simon for hours and end up falling asleep to his lovely calming voice. Are you just too into the really cool puzzles? 😺
@@Anne_Mahoney honestly they’re always so creative I love watching them unfold ! :)
@@emma-ro7vh Yeah, me too. So many nights I've sat up later than I should have to see how the puzzle ends up!
I always feel like my IQ has gone up after watching any of your videos because even tho I wouldn't be able to solve this sudoku on my own I understood every step of your solution
Very interesting combination of lines. The no-repeats rule made this puzzle, truly. Some beautiful logic here, which you were great, as always, at making use of and explaining, Simon. Thank you for this video!
An easy way to visualise modular lines is that the cells have numbers from different (but in a repeating pattern) vertical columns of the number keypad.
It does not work on a laptop :)
And for entropic lines it switches to the horizontal. (Although I guess it's easier to just remember the groups 123, 456, 789 🙂).
@@olivier2553 I means as in the sudoku pad - doesn't a keypad in purple appear on yr screen?
@@dwdei8815 OH! Yes of course, I use my keyboard, so I do not refer to that software keypad, so I forgot it.
Simon staring at a box saying the puzzle has been out for only an hour. "Oh noone solve this yet. Is this brand new? Might be."
Since there are several different URLs for SudokuPad, though, it's possible that the puzzle has been solved many times, just not this *copy* of the puzzle.
Of course the bottom teal line is longer than the top one. It is about 1.41 times longer... Because it goes through diagonals (hypotenuses?) only.
Hehe. Smart.
Sudoku over football, priorities set right!
Was there football? French were eliminated anyway, so I am doubly not concerned.
@@olivier2553 yeah, tough day for La Francophonie when France goes out in Euros and Canada in Copa America on the same day.
I love the solve, but I'm a little sad, as it certainly means I've missed one of Zetamath's build a Sudoku streams.
Simon wasn't actually the first person to solve this sudoku. The testers must have made a new version, probably because Zetamath didn't explain the meanings of each line type on the SudokuPad link (he had the explanation on the Logic Masters page).
He spotted the extra region much faster than I would have.
Why is it called "Dovetail", I thought, then when Simon blueified the line and the 3 in box 1.. its a freakin dovetail. The break-in is a dovetail.
I'm vaguely aware of some sort of football thing going on - something to do with "Sealions on a yurt", I believe. Presumably it makes sense in context.
We won 2-1 in the 91st minute of the game to reach the final of the Euro cup for the first time on foreign soil.
Final is Sunday.
@@chipsounder4633 We lost 1-2 after a beautiful early goal followed by a questionable penalty and an almost total collapse in the first half. For a while there was a glimmer of hope in a much better secodn half but in the end the English bulldogged their way to a lay minute clincher. Now I'll cheer for the English on Sunday.
Ghost Voice Simon making an accurate prediction at 52:08.
This is an amazing puzzle. It seems as though there are at least 4 break ins!
What a great way to spend an evening, a million times better and more interesting than football!!
Or do I what I did and watch both!
I'm sure Simon watched the game.
Nice profile picture
L
especially when your team loses to the english...
Finished in 39:34. Intriguing how the lines can only have unique digits on it limits the possibilities for what the lines can be to such an extent to give a break-in with no digits and very few lines.
Fun puzzle!
Does anyone else have a problem with numbers disappearing when solving the puzzles? Im playing through the link with Chrome.
@@MrKongen198 Interesting. My daughter has been experiencing the "glitch" on her phone, but I have not. I had assumed it was just her.
I’ve had the problem for weeks. Hopefully they fix it soon, because it’s really annoying
@@wardtielens3677 Have you reported it?
Loved the Pirates of Penzance/Major General's song reference you snuck in there.
Beautiful puzzle, thanks. I think I found a more elegant way to resolve the ten line, but I missed the row 5 logic so was slower to sort the middle boxes.
mom chose football, I chose cracking the cryptic 🫡
The 248 triple in box 2 appears to be celebrating Colombia's semifinal win in the Copa America 🇨🇴
Finished in 43:39. Needed to rewrite (and considerably shorten!!) the rules and keep them in a text doc on the side! Still a fun puzzle, though, just .. complicated 🙂
That was a hard fight 😅 but really genius 👍🏻
Ok, I haven't started this yet, but with 8 different lines in one puzzle, I predict pain trying to hold all the rules in my head. :)
While it's certainly true that it can't repeat again,
I think it's probably more important to note that it can't repeat.
And, if it can't repeat the first time, it certainly can't repeat again.
It took me quite a while to find the breakin, but brilliant puzzle. Managed it in 77:44
Just wondering if capitalising puzzle components in the instructions would make them quicker to refer back to ('RED LINE', 'TEAL LINE' etc. in this case).
Excellent puzzle! I was very slow at solving this, but I enjoyed it all the way.
25:23 in column 9 the 8/9 goes with 2/1 to make 10. In row 3 the same 8/9 goes with the same 2/1 and a 4 to make 14. So the 89 is placed. (spotted at 30:40)
I solved this while watching the Great British Sewing Bee - really nice puzzle, with the usual thought points for a Zetamath. I was going to complain about the colours not being so colour-blind friendly, but the version on LMD is nicely disambiguated in the diagram published there.
That was really hard work and it took me more than two hours. Now I'm curious how Simon has solved it .... I"m sure his way is the better one. Great puzzle.
Solve time 48 minutes puzzle upload time less then an hour, Simon chomping at the bit for wonderful puzzles
"It was very very clever" - your solution? I agree!
Great puzzle! Managed most of it without aid of Simon. Only just in the beginning 🙂
Dude, I am colour blind. Good fortune to the rest of you.
Fortunately there's a colour-blind-friendly version that marks the appropriate lines with 3-letter shorthand, though you have to read the rules elsewhere.
And just as I am watching Simon get to the break-in in the puzzle, England scores in the 90th minute. 🎉
Super substitutions.. was a great pass from Palmer. Hope the team can step it up another level to beat Spain on Sunday 🎉
this one was super hard and convoluted. got stuck like 10 times haha
21:07 for me. Very interesting puzzle!!
I did it, took me days!
Thank you Simon for showing us the beauty of this logic. I finished the puzzle with hypothesis that happened to be true, and it's always frustrating me. ^_^ (Yeah, I'm kind of cringe, I know ^_^)
Genius
YESS ANOTHER ONEEE
Grey and teal? Sorry, I only see one greyish color. It's not friendly to my particular brand of color-blindness, I guess.
I don't think I'll be trying this one anyway, though. The video is too long for my comfort level.
(Edit: I see the color-blind friendly link now. Good to see someone has already taken it into consideration.)
Hurray, you removed the colors once they weren't adding value!
Solved it with help from the video.
21:50 Wow, I actually did better logic than Simon! Unheard of! Or, I did the logic on the grey line and he didn't see it/bother. A case of needing to do the pencil marking!
52:36 - YES hahaha it always is nonsense sudoku that you can't see!
A LOVED IT 😂😂😂😂😂😂
What is this football?
10:56 Why cant you repeat numbers on the line? The top right section could be 7/1/2. The Box 1 section 2/5/3 with the 2 being in R3C3. And then Box 4 6/4 or even 8/2 tripling the 2. I dont see anything wrong with that.
It's stated in the rules.
@@davidh.4944 Oh in the beginning i see i read the part about the circle line containing 5 different digits and assumed in my head that therefore all other lines could repeat digits completely ignoring the beginning thank you. I read the rules 5 times or so and never saw it confirmation bias is crazy.
@@jonkess2768 Happens to us all occasionally. 😝
These people need to use better colors for these lines.
We've added a colour-blind friendly link in the video description.
@@CrackingTheCryptic love you thanks
24:06 for me
Does anyone else actually struggle with these or is it just me? Seems like every comment is some version of "20:15 (sudoku checker off)." Meanwhile I already know if I actually decide to get stuck in its going to take me a week and 100 lines of python code.
I can do about half of the puzzles presented here without any help from the video. And that is only after watching Simon and Mark for years now. You are not alone.
71:00
68:53 for me
29:00 for me. about average difficulty
Of course sudoku as they dont have there secret 9 footballs in row sum up to 45 goals.
wow, this was a bit of a be-atch.
What game? Not interested in football.
