▶ NEW PUZZLE/SUDOKU HUNT JUST RELEASED!!◀
We've just released a really amazing puzzle/sudoku hunt by Matyas Martinka. Any correct solution gets a shout-out on the channel!
/ crackingthecryptic
*********************************************************************
Today's puzzle... let's just say it's at least tricky! It defeated every tester we sent it to but it came strongly recommended from the Discord server. It marks a debut on the channel for Miky - the sudoku is called Sun Chariot and if you can find a logical path through it then give yourself a huge pat on the back. You can play it at the link below:
app.crackingthecryptic.com/su...
Rules:
Normal sudoku rules apply. Cells separated by a single knight's move (in chess) cannot contain the same digit. Digits along an arrow must sum to the digit in that arrow’s circle. Digits may repeat along an arrow if allowed by other rules. In cages, digits sum to the small clue in the top left corner of the cage. Digits cannot repeat within a cage. Cells sharing a black dot have a 1:2 ratio (and not all possible dots are given). Clues outside the grid give the sum of the digits along the indicated diagonal. The digits on a diagonal may repeat.

So our brave warrior Simon puts on his super powered spectacles and stares down this puzzle with nothing less than 100 percent determination and says " you've crushed 3 of my testers, but I will be damned if you're going to take down me!!!" So after a bloody battle for well over an hour our hero Simon Anthony stands over a rather colorful but defeated grid and once again claims victory.

"I'm sorry I'm not cleverer - It's something I lament all the time but that's the way I was made", says Simon - just after solving a top-difficulty puzzle that stumped three testers.

But this means... the end of the thermo in the 27 cage has to make a 5,6,8 triple next to the green star. And has to extend down.

I think you’ve said in the past that your testers are anonymous to the viewers, but I’d be really interested to know if they would answer questions about this puzzle. It would be very interesting to know if they were all stumped at the same point, or if this puzzle ground them to a halt at different points. I’m not sure which implies the puzzle is harder actually, that all 3 testers fell at the same hurdle, and therefore three brains couldn’t overcome the same choke point in the puzzle, or that the puzzle had enough challenge that it stopped all three in different places.

I did have to go for some help from Simon, but I solved it after having watched only half the video, and if you check where he is at that point, I think that's still a bit of an achievement. :) I think the key was noticing how the constraints let you map the cells from box 5 out to a few places in the surrounding boxes, which let me do the coloring.

yeah noticed that too, but I thought that this might be an incorrect statement, to say if there are 2 candidates in the cell and one of them is black, and we know that black = 4, then the remaining candidate is 5, is it true to say that purple is 5?? there is a slight feeling that this logic may be erroneous

@JesteR00160016 Год назад

@davidstorrs 2 года назад

Simon, give yourself credit! You're saying "oh, I'm not clever enough" after doing a stupid hard puzzle! Well done, man. This one was satisfying for me because I actually got it. I mostly went along with you, sometimes jumping ahead, getting stuck, and then going back to the video for some help. Once you started coloring the 5789 squares I was able to go ahead on my own. Of course, I was a lot less efficient about it -- you did some of them, then went to the diagonals and finished everything. I colored every single square (using a silver flash to mean "maybe none of 5789"), unwound everything until I had locked down the 5789 squares, THEN went to the diagonals and sorted it out. Much less efficient than your solution but I did get it on my own. Thank you for all the lessons you've given me; I've really improved as a solver since watching this channel.

@Jodawo 3 года назад

There was a technique that was featured on the channel before. It was a technique built upon Phistomefel's Sudoku logic by someone else. If you look at the 5x5 square in the top right corner and compare it to the 4x4 square in the bottom left corner, you can see that the 5x5 is actually the same as the 4x4 minus a set of digits one to nine. If you take out box 3 and box 7 you will notice the killer cage has the 45 extra that if taken it out of the 5x5 it will be exactly the same as what is left from the 4x4. I was very surprised Simon didn't catch that. From that point, it would be clear that you would be working with 6 and not 8 since the Kropki Dots would make it difficult for the numbers that make up 8 to be on them. If you notice on the Kropki Dots there is 1, 2, 3, and 6. The other 1, 2, and 3 are in box 5 on the arrow (that is part of the 5x5 square).

@krytolandros1775 3 года назад

That's a great way to open the puzzle! Nice catch.

@TheSplunger 2 года назад

This is how I ended up starting it. Boils down to (both kropki) = 2x (the circle). Then kropki sum to divisible by 3, so circle is 69, and 9 won't work .

@joaoricardo9174 3 года назад

One quicker path to rule out the 8 in R6C4 is to use geometry to figure out that 2x R6C4 is equal to the sum of R1C5, R1C6, R4C9, R5C9 (the 'top' and 'right' kropki dots). You can't make two black kropki dots add to 16, so it cannot be an 8. To me, the arrows and shape of the box are very suggestive that geometry would be useful

@ludovicoleporeo2407 3 года назад

Good catch! Since it took me a good ten minutes to understand, I'll write down the steps for people as dumb as me, but lazier. We look at the cross composed by rows 4,5 and columns 5,6: it adds up to 4x45-R6C4-R4C6. But the left, center and down boxes are 45-R6C4; add to that 45-R4C6 (the cage, except the element we've already counted in the center box) and the two dots. So we have the equation 4x45-R6C4-R4C6=3x(45-R6C4)+45-R4C6+dots, that we simplify to 2xR6C4=dots. (Well, this is how I've seen it. Maybe there's an even simpler way?)

@WhoStoleMyAlias 3 года назад

Wow! This was crazy difficult. Totally flunked it on the first attempt where I figured the arrows should add to 8 based on the thought that they couldn't all contain the same digits. On the second run I managed to get the whole grid coloured before even attempting to figure out the math on the little killers and I got the 8 from evaluating odd/even.

@NijiRanger 3 года назад

Clearly a new all time favourite. Amazing. Such clever and unexpected logic throughout. What really did it for me was the end. I did it a bit differently, where i filled in all the colours before touching the little killers. So i had about half the digits, and then had to consider both killers, think about parity, and see what colours were repeated across them both. Possibly the best use of disambiguating little killers i've ever seen. A beautiful finale to such a wonderful puzzle.

For anyone curious when Simon thought he broke the 6/8 and didn’t his flawed reasoning was that the three would be forced on a kropki and into the other square which would rule 3 out of both 8 arrows and break the puzzle. But, as he was explaining he said that the 8 rules the three out of the kropki anyway which is true but threw his previous logic out the window and Simon for a loop

@@brock2k1 On "Simon", since you show an interest... I think you'll find that's Celtic "sluhgn" entomologically related to the Norse "S!hlo÷ng-b'jdrn" which was a small pot to keep herring in while voyaging overseas. This is openly depated academically*. "Wally" however was an Anglo-Saxon term for a serf who performed animated, repeatable duties on an ocean going vessel which travelled to distant planets and have some love interet with another, high-born member of society. * not true.

I found it easier to disambiguate the 6/8 with math. Thanks to The Secret, we know that boxes 2, 5, and 6, minus the killer cage, add up to 90. Then if there is an 8 in the circle, the parts of its row and column that aren't on the arrows (and thus are in boxes 2, 5, and 6) each add up to 45-8-8=29. Subtracting the 8 in the circle, the arrow in box 5 that adds up to 8, and those two 29s from 90 leaves us with 16 for the Kropki dots. And we know that the dots are 1, 2, 4, and 8, which adds up to 15, so that doesn't work. And of course putting a 6 in the circle does work because you instead have 90-33-33-6-6=12, which is perfect for putting 1, 2, 3, and 6 into the dots.

A little while ago I thought I would never be able to create a sudoku, two days ago I did create my first sudoku and happy as a lark I am now working on creating my second one. And then I see this. Not happy anymore. The ability to create something like this seems so far beyond conceivable that I seriously consider crawling back into my coffin and asking my altruistic neighbor to dutifully nail the lid shut with silver nails.

@achad1607 3 года назад

I did it! I did it! This is the hardest puzzle I ever solved! I never resolved the 6-8 until I placed a 1 in r5c6. My solution path was roughly, eliminate 48 from the kropki dot in box 6. Place the 2 in r7c7. Set the kropki dot in box 3 as 36, [eliminating the 36 for the kropki dot in box 2.] Restrict the 4 in box 5 to either r6c5 [6-8 resolves to 6] or r5d6 [resolves 6-8 to 8] See that r45 and r8c4 were a 14 double. Then, analyzing where the 1 can be box 3, deducing the kropki dot in box 2 is 1,2, which put a 1 in r5c6, meaning, only now did I know it was 6's, and, not 8's. After that, I didn't figure out the setting of 4's, so took a longer path, but, similar one. On Simon's solve, something helpful is to consider the parity of the 32, and 23 arrows. The repeated digits are always even after doubling. Over ten hours work!

What a beautiful puzzle. I don't think it's the hardest you've ever solved, though. I managed to do the post break-in bit in half the time you did by colouring every single cell in the cage and doing knight's sudoku with the colours. Not a hope I'd have been able to solve this sudoku without the multi colouring ability on your website though! Granted, the break-in bit took me likely at least 10 times the length of time it took you but I'm taking my victories where I can.

@Raven-Creations 3 года назад

Wow, that was brutal! I got the 1236 sorted fairly quickly, but then stalled. I wish I'd known about the cross pattern that was used to get the 4 in box 5. I wasted a ton of time on that. The logic in boxes 1 & 2 to place the 4s was easier to spot for me. I'd already worked out that R1C4 = R2C3, and since R1C4 couldn't be 4, the 4s had to be R3C3 and R2C4. It's the same logic Simon used, just looked at from a different angle. The construction was brilliant. I was particularly impressed with the way the main arrow cluster resolved to 6, using all of the arrows, the cage, and the dots.
