** IT'S LIVE: OUR KICKSTARTER CAMPAIGN LAUNCHED **
Thank you so much to everyone who supported our Kickstarter yesterday - the base book funded in just 2 hours!!! Now we're trying to meet stretch goals to make the book everything we think it could be :)
Want to take a look at Cracking The Cryptic's Greatest Hit Volume 2. Here's the link:
www.kickstarter.com/projects/...
** TODAY'S PUZZLE **
[Apologies for the ludicrous picture in the thumbnail. Peter - our Kickstarter organiser - has been creating anime adaptions of real pictures, with comedy effect!!]
Cut In Half by Adem Jaziri has been described as "one of the most enjoyable puzzles I have ever solved" as well as earning "mind blown" emojis on Discord. It's just a fabulous (and APPROACHABLE!) sudoku.
Give yourself some free joy and play the puzzle at the link below:
app.crackingthecryptic.com/su...
Rules:
Normal sudoku rules apply. Digits may not repeat along the main diagonal marked in blue. Clues outside the grid give the sum of the digits along the indicated diagonal. Cells separated by a knight's move (in chess) cannot contain the same digit. Grey lines are palindromes and must read the same forwards and backwards.
** OCTOBER MONTHLY REWARD - OUT NOW **
The Duality Sudoku Hunt is just out. Massive thanks and kudos to the Sudoku Skunkworks for creating such a brilliant set of puzzles (14 in all!). You'll be able to enter the competition if you can solve the first 4 sudokus. If you solve all 14 by 20 October, you'll get a shoutout.
We've also just released Simon & Mark's solve of Vignettes by zetamath, which you can play at the link below:
app.crackingthecryptic.com/su...

If someone told me last year that I would be addicted to Simon and Mark, 2 sudoku solvers at youtube, I would have bet against and lost everything.

@garrettsmith9788 Год назад

I am not addicted! I merely choose to watch all the videos they publish.

@piarittersporn Год назад

@@garrettsmith9788 I used to think that about myself too. Now I take my tablet with me to the toilet.....

@Andreas You might have lost the bet, but you certainly would have not lost everything, because now you have sudoku :D

@overland4xe880 Год назад

Addicted to crack eh? Maybe that joke was bad but it still cracked me up 😅

@georgeaman1938 Год назад

I have to admit the same.

@thorbjrnhellehaven5766 Год назад

I loved the ending, where Simon keeps scanning for some fractions of a second, then suddenly realised the puzzle was finished ✔️ ❤️

@cramias1 Год назад

One of the things I find addictive about these videos is, even though I am in no way able to solve a puzzle like this from start to finish myself, I'm occasionally able to get one step ahead of Simon or Mark on a piece of logic, and when I'm able to do so its very satisfying. In this case it was realizing a 36 pair in row seven made yellow a 2, much earlier than Simon worked it out

@diegobolso2005 Год назад

@Blake Robinson great tip, indeed. That´s probably how most of us have improved at solving sudokus ourselves. There are other channels that feature easier ones, but definitely Simon has something that attracts us all!

@ahouyearno Год назад

@Blake Robinson Also just start the free 500k subscriber pack. I did a few of them and they were brilliant. The first few aren't too hard. Being able to solve an Aad van de Wetering and aspargtacus really made those days.

@TheofilosMouratidis Год назад

From 25:38, you can see that r3c9 can eliminate the 2 from r7c9, then you are are left on box 9 on the diagonal with 36 36 and 236, so yellow is 2.

@Dad_Jokes87 Год назад

I really loved this puzzle. A great reminder that a puzzle doesn't have to be hard to be beautiful. Great solve Simon!

@RasperHelpdesk Год назад

One idea for puzzles with colors like this, when you solve a digit (like when you had placed all nine 9s, 1s, or 5s) color that digit dark grey. That both frees up colors (red in this case) and also makes it easier to scan for "Can X be Y?" because if Y is dark grey you'll know that nothing else can be it.

@emonstermark699 Год назад

I don't always finish these puzzles without any help....but when I do, Simon always says, "That puzzle wasn't too difficult" at the end of his solve. :(

@erlandodk Год назад

Simon's surprise when he finished the puzzle "just like that" is pure wholesome gold. 🙌

@philipstaite4775 Год назад

I found 2 in box 4 early on by looking at the palindrome line. That helped sort out a lot. Left me doing colors with 47 and 36 pairs, figured out a couple of random 8s positions... Finally came down to the 20 diagonal sum to resolve everything. Really fun stuff!

@phuybrechts6875 Год назад

Simon mist this one !🍳

@gumpertapollo27 Год назад

That mirror logic between the pairing is perfect. 5 with itself, 9 with 1, 8 with 2, 7 with 4, and 6 with 3. It's a beautiful puzzle. The diagonal mirrors it's pair along the diagonal and the numbers mirror it's pair on other sides of the diagonal. Beautiful to look at.

We smashed through three stretch goals!

@ThePs3GAMEr2001 Год назад

I love trying these puzzles hardly getting anywhere with them then watching Simon breeze through it

@andymoss Год назад

The 2 in box 3 solved for 2s everywhere by removing the 2 from the 236 in box 9. Also, “That’s green in the corner…” I’ll get my coat….

@arthurcharest9061 Год назад

This was the first puzzle that I really felt like I kept up! I love the way you stop and explain while also giving us time to pause and see if we can get it too!

@craftsmanwoodturner Год назад

Simon says that it's not difficult, but I couldn't get anywhere, so I sat back and watched him blast through it with alacrity. It makes me feel like a T-rex watching flower arranging - I follow every step, but there's no way that I could do it myself.

@chiderakalaji7206 Год назад

What a beautiful analogy

@victorfinberg8595 Год назад

but you are still the king of them all

@FredT34 Год назад

Same here, couldn't even start!

@victorfinberg8595 Год назад

@@FredT34 You don't need to be as brilliant as Simon to solve this puzzle. Indeed, this puzzle is a good demonstration of how to use standard procedures to solve intermediate variant sudokus. The first thing to be aware of is that this is a "miracle" sudoku. Starting from apparently nothing, you can solve this puzzle, which appears to be miraculous. This generally involves a knight's constraint. This constraint is so powerful that two givens, or even one, are typically all you need to get all instances of that digit. To start this puzzle, look at the diagonal clues. They are all pretty average. You will get no joy there. Don't waste any time on them. Only the palindromes are even vaguely interesting. To the untrained eye, they look useless, but try a couple of things before you give up. Pick a cell and its duplicate. May as well start with an endpoint. May as well use the box 2/4 endpoints. No analysis is needed yet. Just fill in all possible candidate cells around the grid in any box that's even slightly restricted with a colour splash. ignore box 9 for now. As you do this, look for any restricted cells. You do need to know the knight's rule patterns. The fact that r5c5 is the only available cell on the long diagonal stands out immediately. This now allows you to strongly reduce the candidate cells in all the other boxes. Indeed, you get all 9 occurrences of that digit in the grid, and you can use the killer clues to find that it must be 5. So you're off to a very good start. Rinse and repeat. As you can see, you don't need to do anything more than apply a simple, known procedure.

@tomtheultimatepro Год назад

23:23 for me, knight's move constraint is definitely one of my favorites

@rosiefay7283 Год назад

It's certainly very constraining. However, the consequence of that is a lot of roping, and that means there's not a lot of variety among anti-knight sudokus.

@Gonzalo_Garcia_ Год назад

12:14 for me. Very enjoyable indeed, great puzzle!!

@markp7262 Год назад

21:27 finish. Another wonderfully colorful puzzle! Took me a bit to spot the break-in, but then flew through the coloring. Excellent!

@Gnarlf Год назад

Amazing puzzle. Took me way to long to see the break in, but I did and from there on it was just lovely. Thanks for featuring beautiful puzzels for all skill levels! You guys are the best.

@brenthooton3412 Год назад

Usually when I see Simon's video is more than 30 minutes, I figure I have no shot. Glad I stuck with this one. Took a couple tries but it was a rewarding solve using judicial use of colouring. The opening with 5s, then 1s and 9s, was enough to convince me to keep going.

@jamscone_ Год назад

THAT THUMBNAIL ART its so nice oml great puzzle and lovely solve 🙏

@clarityc481 Год назад

Oh how fun! This is one of those puzzles where somehow I end up coloring twice as much as Simon (which is saying something!), but I was entirely here for it. The palindromes and the knight's move sets work really beautifully together into just the sort of puzzle I love, bounding around the whole grid to put the pieces together. A pleasant, leisurely 40:20 for me. Thanks so much for sharing!

Thank you for what you've taught me over these months that have brought me to this point! And as for the thumbnail to this video, you are resplendent in a coat and tie - you do clean up nicely, even if it is just manga or whatever you said. I did try the puzzle, got bogged down somewhere, and decided to finish out by watching you. Now I'll return to my effort and solve it. Thank you for this great video, and for the new book coming out, and all of the excellent content on this channel. Endless fun.

@ryanbritt6874 Год назад

I took quite awhile longer than Simon but I'm proud to say I finished this puzzle all by myself. There's absolutely no way I could have done that before finding CTC. Thank you so much for all the fun and entertainment you provide!

@Raven-Creations Год назад

Approachable you say? Try doing it without the anti-knight's rule. I'd been at it 20 minutes before I realised my mistake. After that, the break-in was spotted almost by accident. I had earlier coloured both lines, and I was wondering whether the ends of both lines could be the same, then thanks to Sir Helpsalot, realised they _had_ to be the same, because both could only go in the centre cell, and this forced both 16 and 24 diagonals to have triple 5s on them. What a brilliant break-in. After wondering why on earth you seem oblivious to the effect of the 2 in box 3 on the 236 triple in box 9, at 25:07 you highlight the very 2 that means R7C9 can't be 2, leaving yellow as the only place 2 can go, yet you just don't see it, saying "the problem is yellow could be 2". Use your eyes, yellow MUST be 2. Your new specs clearly haven't helped.

@davidrattner9 Год назад

Very elegant, flowing with superb setting!! Great puzzle to be featured!!

@Swisswavey Год назад

That was brilliant. I struggled to see a lot of the logic so it took me a long time, 64 minutes or so, but when you see the logic there are "wow" moments everywhere. It helps to remember the Knights move constraint too, that counted for about half an hour of wasted time!

@mcalphax Год назад

20:40 Great puzzle! Used a lot of different techniques to get to the finish while it felt like I was flying through it. Love the combination of the knight's move constraint with other variants.

@AdmiralMinell Год назад

My technique for coloring is to use light gray flashes to show options for the first 8 digits, but then at the end, treat light gray as the 9th digit, delete the flashes from anywhere that sees a light gray, and you're just left with the options for that group of cells.

@abegley6588 Год назад

It sounds bad but your videos help me fall asleep. They're interesting enough that I don't mind watching the videos through (and possibly multiple) but the videos are still calm and chill enough that they help me relax (except when I'm mentally yelling at Simon about a digit for five minutes). It's become my night time routine to watch (and sometimes fall asleep to on some of the longer vids) cracking the cryptic! Definitely something I look forward to every night

Puzzles like these are why I hope Simon never gives up on coloring, they way you can just find where a digit goes in every box without even knowing what digit it is is so amazing, and it would be so much less satisfying to watch if he used letters instead.

@wariolandgoldpiramid Год назад

lovely and elegant puzzle today, that was fun to watch :)

@Xehanort107 Год назад

I needed the first step. I was clueless on how to start this. I did something completely different to see the 47 and 36 pairs. I noticed some cells looked at both sides of the pallindrome, so they had to be the same. Unfortunately, it forced me to make guesses and pray, but it ended up looking more beautiful knowing that the pallindrome was how you see the similar cells throughout the entire grid. I like it when the entire grid just fills with pairs and one thread just untangles everything.

@jurjenvanderhoek316 Год назад

25:44 Right here you could have placed a 2 in r9c7, because the 2 in r3c9 rules out a 2 in r7c9 (which you could have pencil marked already at 19:31)

@srwapo Год назад

17:50, SHOCKED at my time. I think I got lucky clicking on the ends of one of the lines and using the knight's move restraint to go around the board as one of the first things I tried.

@Paolo_De_Leva Год назад

Simon was spectacularly brilliant at the beginning, then he missed the easiest and most powerful deduction❗ At playback time 23:13, the answer to his question should have been: _"no, that cell cannot be blue"._ This would have markedly simplified the following steps. It would have allowed him to place *blue, green, 8* and *2* everywhere before using the *11-diagonal.* This approach is amazingly gratifying, because immediately before pencilmarking the *11-diagonal* the grid appears full of colours and digits but totally clean, with no pencilmarks.

@dsquirrel Год назад

For those (like me) who don't see this instantly: 1. Suppose r6c2 and r3c5 were blue (they have to be the same by palindrome logic). 2. Simon's just noted that blue in box 1 has to be in r2c2 or r3c3, each of which sees one of the blues we've just posited. So neither r6c2 nor r3c5 can be blue. 3. Now consider where blue can go in row 3. r3c1 is ruled out by sudoku; r3c4 is matched with r5c2 on the palindrome, and the latter sees the blue in r5c8; we just ruled out r3c5; r3c6 is ruled out by knight's move; and all the other squares save r3c3 are already populated with values that are not 4 or 7. So r3c3 must be blue. 4. Plain sudoku now gives us blue in r4c2, r2c4, and r6c5, completing the blues. 5. We can now colour r5c2 and r3c4 green, and proceed just as Simon does later in the solve to place all the greens in the grid using sudoku, knight's move, and the diagonal. 6. Note 2 can't go in r6c2, because by palindrome logic this cell is identical to r3c5, which sees a 2. That puts 2 in r5c1, and remaining 2s follow by sudoku and knight's move. 7. For the 8s, place 8 in r5c9 by sudoku, then eliminate 8 from r6c3 by knight's move, meaning the 8 in box 4 is in r6c2 by sudoku. By palindrome logic we also have 8 in r3c5, and the diagonal constraint gives us 8 in r2c8. The remaining 8s follow by sudoku.

“Oh. That’s finished the puzzle, apparently.”

@myfyrmadocjones Год назад

Interesting symmetry. Turn the puzzle round 180 degrees and swap 4 and 7, 3 and 6, 2 and 8, 1 and 9, leaving 5 alone and you get the same grid.

Fascinating puzzle!!

All 2's and 8's could be done the moment the appeared on the little killer if palindromes logic had been used.

A really nice coloring puzzle. Good solve.

Since this started out as a colouring puzzle, I thought I'd challenge myself and see if you could colour in the whole grid, without ever entering a single digit (so, completely ignoring the diagonal sums). That's 3 hours of my life I'll never get back. But yes, it is in fact possible!

Great puzzle, great solve.

Yatta! That was a really fun puzzle!

@23:27 the blues all solved miracle-like [That did it for me for that 20 diagonal] Nice

@michaels4340 Год назад

66:51... didn't check whether the grid was rotationally symmetric or not, that probably would've helped :P very pretty puzzle, though!

The author of the Garfield comics is a CtC fan?! I would never have guessed that!

@victorfinberg8595 Год назад

Starting at 19:45, my solution diverges strongly from Simon's. Based on the principle that this is a miracle Sudoku, I looked at specific digits across the whole grid. All the 2s and 8s can be completed in short order, and then i fully colourized the remaining 4 sets of cells, disambiguating only at the very end.

Loved it!

Simon just namedropped agadmator and now my day has been made lmao

A very rusty 80:05 from me! My first solve in a few months though, couldn't resist the knight + palindrome, which are some of my favorites

@nickatty462 Год назад

Everybody's saying how great and approachable this is. I've spent about an hour on it, in more than one session, and have not *nothing*. I can see from the comments that the idea of colouring is important (which I'd guessed!) but all I end up with is dozens and dozens of places where something might just be. It's so built up that I don't want to spoil the fun by watching the video, but I fear I might have to.

@nickatty462 Год назад

I'll eventually get that instinct for the knight's move. I'd spent ages looking at the ends of the palindromes and never linked them to the middle. Ah well!

@rainbowk1ng Год назад

That was crazy using colors for process of elimination 🤯

@Rach881101 Год назад

32:49 for me. Made a little error in the coloring at the end, but was able to fix it. Great puzzle!

29:10 - and that's green in the corner... 😁

@larsscholz3762 Год назад

21:32 Oh Simon, you just proved that blue is equal to red, so your two blue cells must be 5s, right? That's how that works, right? ;-)

@SomethingWellesian Год назад

I went by completely the wrong path in starting this (I’m still pretty new to solving) and got frustrated and lost. Beautiful to watch your solve, though, even if I was cursing myself throughout.
