** TODAY'S PUZZLE **
A debut on the channel tonight for The Book Wyrm and their puzzle Colour Wheel, which was apparently constructed in just 90 minutes. This will seem utterly extraordinary when you see the logic required in this one - it is original and brilliant (and not that easy!)
Play the puzzle at the link below:
sudokupad.app/bBR8Rj8Ng7
Rules:
Normal sudoku rules apply. Digits in a cage do not repeat. Sum all the digits in a cage and then colour each cage according to the last digit of its sum (i.e. cages that sum to values with the same last digit are the same colour, and cages that sum to values with a different last digit are different colours). Numbers in the top left corner of a cage (“Cage X”) give the sum of all orthogonally-adjacent cages of different colours to Cage X. Every digit, except the digit in the central cell (r5c5), has a 'partner digit' that is always placed 180° rotationally symmetrical to it, seen from the centre of the grid. Which digits are paired up must be deduced by the solver. (Example: If the digits 1 and 2 turned out to be a rotational pair, and r2c4 is a 1, r8c6 must be a 2.)
** NEW SUDOKU HUNT ON PATREON **
Simon's solve of Sky-Skyscraper by Phistomefel has just been uploaded for our patrons. Also on 1 June, we have an incredible new competition: A Lord Of The Rings sudoku hunt by Blobz (featuring the artwork of Ted Nasmith). This one is not to be missed!

@TheBookWyrm438 21 день назад

Hi! The Book Wyrm here. Thank you for the feature, really looking forwards to watching this soon. Also, to clarify: this version of the puzzle was not set in 90 minutes. The version set in 90 minutes had an error at the start, so I edited and improved it after to reach this version (so probably 2.5-3 hours of total setting time to get this). Most of the logic is the same as the first one, up until the ending part (once the 22 and 32 cages become relevant).

@sturmey1966 21 день назад

I read your rules several times. I still don't know what they actually are, and I watched Simon solve it.

@jdyerjdyer 16 дней назад

I solved it, but the ruleset hurt my head and made me back track many many times. Total solve time: WAY TOO LONG, lol. I did enjoy the puzzle, but I kept mixing up cage sums and difference sums. I finally had to pull out a notepad and take notes so I could figure things out without mistakes. I did fancy how it had you bouncing around from cage to cage, across the board and back with partner cells. Thanks for the given pairing, btw! I doubt it's solvable without those two given digits. lol Also, all the math slowed me down drastically, too. I can't do this math in my head so easily. How you set this puzzle, I'll never understand, but bravo!

That had something to do with you, too. Because, there was a channel that I unsubscribed to (there's probably 20 million subscribers by now), but I haven't got a notification for that channel in years.

Thank you, Simon, for keeping me company for at least 1 hour a day.

@dumediat_ 21 день назад

I'll add a bit of lore to this puzzle, if I may. From March through May this year, I held a 32-player bracket tournament (akin to March Madness in the US) in the Sudoku Skunkworks. The format was that each setter selected a constraint to use against their opponent for the round, and they didn't know which constraint their opponent picked until they started their 90-minute setting timer. For the quarterfinal round, The Book Wyrm selected this "Colourful Killers" constraint, and their opponent (Myxo) selected rotational pairs. So, not only did The Book Wyrm set a version of this puzzle in 90 minutes, but they also had to figure out how rotational pairs would interact with colourful killers *within that same 90 minutes*! Truly mind blowing, if you ask me.

@davidrattner9 21 день назад

Thank you so much for sharing that!! Couldn't imagine the 32 setters involved and all the absolutely phenomenal puzzles that were created! Able to share who was pitted in the Final against each other and who won?

@mikew6644 20 дней назад

So both setters then had the same 2 constraints ‘stacked’ on top of each other for their 90-minute session? Or I set using your constraint and you set using my constraint? Also, this seems like fun! How were winners from each round decided? Solve time? Set time? Judging for quality of puzzle? Something else?

@davidholt4327 21 день назад

Very proud of my deduction with the red cage - when you had 125 in the cage in box 7, it was only possible for it to map to 345, cos if it mapped to 245, 3 wouldn't have a partner. I think that was simpler than the way Simon got there. I'm quite good at little deductions like that after Simon has done a load of hard work first!

@zoet. 21 день назад

I reached the same deduction using the 2. 2 can't map onto itself, and if the 1 in box 7 maps to a 2 in box 3, then the 2 in box 7 must map onto 4, meaning 2 maps onto two different digits, breaking the pairs constraint

@jasonfire3434 21 день назад

You don’t even need that deduction, it should be obvious based on the middle box that every digit must have a different digit as a partner except 5, so once the 8 cage became 125 the red one had to be 345.

@davidholt4327 21 день назад

Not necessarily. 125 could map to 125 by the pure ruleset, if 1 and 2 are pairs. But yeah, there couldn't ever have been ONE match between the digits in the lower tuple.

@zoet. 21 день назад

@@davidholt4327yes, but at that stage 125 was not an option for box 3 because the cage's sum needed to equal either 11 or 12, making 245 / 345 the only options. Since 2 can't be both paired up with 1 and 4, and can't reference itself, the only viable option was 345.

Your personality is one of the top reasons I’m subscribed Simon.

@steve470 21 день назад

At the 34:40 mark (where the purple cage would be summing to 21 and the yellow cage to 12), a quicker way to disprove this is that a 3-cell 21 must include at least two of 6, 7, 8, and 9. Those digits map onto each other, so you'd have a 3-cell 12 that includes at least two of 6, 7, 8, and 9. That's too much.

@davidrattner9 21 день назад

Lovely solving Simon with your energetic enthusiasm and personality as only you can provide!!

@RichSmith77 21 день назад

What an incredible puzzle. I cannot begin to imagine how someone goes about setting something like this. Mind blowing. I was feeling pretty pleased with myself that I'd got all the central box logic at the start, that Simon had found by around the half hour mark of his solve, but then I hit a brick wall and couldn't see how to progress. I had to watch Simon for a tip on the way forward. Ruling out the two cell cage r7c56 from ending in 5 was the hint I needed. (Although, initially I thought it would be blue if it summed to 10 too, as I momentarily confused ending with 5 as the same as being divisible by 5. Doh! For a brief moment I thought Simon had overlooked something important, then I realised my error.) I managed to solve the rest from that point on, though, with no more help from the video. I'm more than happy with that.

@skosichm 2 дня назад

CTC geniuses through and through. This is certainly my new addiction for 2024 (hence why every time I open the page, I pronounce the channel "Crack In The Cryptic". Simon/Mark -- have you ever considered talking to the setters about making short videos the do one or both of the following: 1) describe how they set the puzzle, and 2) walk through how they thought the solve would go ?? I think it would be really fun, especially after I have given it my best try, used your solve video to aide me along the way, and then still faffed my way to errors of many varieties. I think the setter videos would be a truly enjoyable companion and a tribute to that portion of this puzzling nirvana. Thanks for this whole world you are sharing with us. I am really enjoying it.

@vandelay33 21 день назад

At 54:42 you finish some very complex logic to figure out the composition of the red box and the 1-2-5 blue box. But it is as simple as "if 2 is in the red box then it must pair with itself (against the rules/box 5) or 1 (which would then put a 1 in the red box)". There is no need to use any other info than the 1-2-5 box and the red box.

@NinjarioPicmin 21 день назад

Whoa, that was so complicated to me, i got stuck multiple times early on and had to wait for a clever thought of simon to catch up and continue but in the end i managed to complete it with _most_ of the logic actually being found by myself. Granted i would have never completely solved it on my own, but just how do you even come up and set this in 90 minutes, it took me hours to solve WITH help 😂

@Vedvart1 21 день назад

An alternate version to get the deduction at 54:40, which I found much easier to see: If the top cage had a 2, then 2 can't partner with 5, and can't partner with itself, so must partner with 1. But then the 4 in the top cage has no way to partner with a digit in the bottom cage; it obviously can't partner with 5, and it can't partner with 2 or 1, because they partner with each other. So the top cage cannot contain a 2 (and that also eliminates the possibility of a 12 or 34 pairing altogether).

@wokkawicca 18 дней назад

Took me almost 3 hours and I had the hardest time internalizing the rules, but what amazing logic!

@chocolateboy300 18 дней назад

I finished in 429 minutes. I was able to get the 5 in the center rather quickly and despite realizing that it is the full cage that touches the cage that gets added up, I proceeded to only take the first cell that orthogonally touched. It turns out that you can get quite far in the puzzle. I was an hour and a half in before realizing that and had to practically start over where I put the 5 in. Then, I spent another couple hours desperately trying to figure it out and unable to do so. I gave up and started to watch the video, before seeing Simon reiterate the rules that no same ending total will count. This completely disambiguated my 31 cage, since 1234 had to equal 5. I spent too long trying to find the trick, only for it to be revealed that it was just the rules of the puzzle that I missed. After that, the ending was still not easy, but at least it was doable. This one was rough in many ways for me. Great Puzzle!

@anthonybailey4530 20 дней назад

Simon, be (non-spoilet) warned: the thing with the (truly wonderful) Braid is that some levels require a combination of both ingenious thinking AND very difficult gameplay.

@Yttria 20 дней назад

I eventually finished with tons of help from the video. I'd guess I figured out 25%-50% of the logic but completely misunderstood the rules at times and even then it was brutally difficult to make headway at times. That said it was a beautifully set with very unique logic that mostly escaped me.

@andremouss2536 21 день назад

23:30 It's amazing how Simon deduces the obvious with far-fetched reasoning : looking at the central box, how could ever 1 match to 1 ? or any other 'low' digit for that matter ?

@homewort-gf2ni 21 день назад

Lovely setting, Book Wyrm and great solve, Simon! An alternative way to see the mapping is to consider the 8 cage and the red cage at the 50 minute mark; if you know that you have 1,2,5 in the 8 cage, then you cannot have a 2 in red cage, because 2 cannot map to itself, and if 1 mapped to 2, then you'd need to put a 1 in the red cage in order to get a 2 in the 8 cage in the first place, and you can't. Therefore, you get a 1,2,5 eight cage, and a 345 red cage.

Kudos to Simon for always managing to grasp key puzzle logic in a short time (yet going the long way around for easier deductions, but that's another story 😅). I mean, while coloring the "first box" wasn't too hard, the real break-in was the next step, i.e. how cage sums could and could not map with each others. It felt quite rewarding to understand it, especially after half an hour sitting there thinking about it.

Finished in 96:59. Was tough going trying to figure out how the cages worked, but after some thinking, I was able to figure it out. I found out though that the 180 degree symmetry was vital to solving the cages, but then I promptly forgot about the symmetry when finally filling out everything which caused a pretty big delay even after I had figured out most of the cages :p. Fun and challenging puzzle!

@aliengeo 21 день назад

Spoilers Felt so clever realizing that there was no way the red cage could contain a 2, because that would mean 2's partner is a 1 (as it can't be a 2 or a 5), which would force any cage opposite a 1/2/5 triple to be a 1/2/5 triple itself.
