After nearly three months away, today sees the return of the master: Phistomefel!!! And it's fair to say he's back with a bang... how this puzzle exists we have no clue but let's just say this is a(nother) work of genius. Do give it a try at the link below:
app.crackingthecryptic.com/su...
Rules:
In every row, column and every bold-bordered area, each digit from 1 to 9 occurs exactly once. The digits in two orthogonally adjacent cells may not be consecutive, nor may they be in a ratio of 2:1.
PS Simon's will be livestreaming The Witness at 10pm UK time TONIGHT (Sunday) evening. We'll announce it on Twitter (@crypticcracking).

"and this 6 rules out a 7 from here so now 7 is locked into this domino" he said, with the given 7 looking at that pencilmark 3 squares down. It's constantly baffling how Simon is able to see logic that I can barely follow and somehow whiffs on the most basic pencilmark ruleouts in the game :P

@serebix3685 2 года назад

To be honest, I feared that he will overlook it till the end of the puzzle like usual. I am glad that this was cleared quite fast for Simons standards :D No hating on him! He is the king of logic in my opinion but his scanning lacks so far behind that its, as you said, baffling at times.

@AkshayKumarX 2 года назад

@@serebix3685 His scanning doesn't lack behind. While the viewer is fixated on that single error, Simon is considering several other options at once, all the while elaborating his thought process to the viewer.

@@youtubeisnotajob4103 It's a rule we saw on other puzzles. Dots can be placed on lines, between two cells. If the dot is white, the two numbers are consecutive (like 3-4 or 8-9). If the dot is black, one must be double the other (like 1-2 or 3-6). Those are two rules used here assuming "all dots are given", which means "none at all". :P

@Da6moose6 2 года назад

Simon is undoubtedly an expert solver. I have been watching CTC for over a year now basically daily. And I have to say his ability to see logic in some of these puzzles is extraordinary. With that being said. It’s very intriguing watching and being able to see how his brain is processing the puzzle differently. Because I am arguably a medium level solver. At no point able to do most of these videos. I rely on scanning more than anything else. Simon is constantly looking for the more beautiful logic in the puzzle which is why I think he misses the simple stuff that has us yelling “THERES A SEVEN THAT GOES RIGHT THERE!!!!” For 5-10 min of the video. Good work Simon. Love the daily content. You’re my lunch break entertainment.

@timothybexon6171 2 года назад

Simon: Noticing things in the weirdest way possible since who knows when. Those 3x3 squares would never be noticed if he just continued doing standard sudoku. But somehow he stops and gets to create bizarre logic that noone else will ever need to think about. Absolutely love these videos.

Gotta say, although it made me take a little while longer I'm shocked color-loving Simon didn't finish this puzzle the way I did: coloring all 28s, 35s and 19s pairs so I could finish the puzzle just by double clicking a color and writing it's digit. Yeah it takes longer, but it doesn't get much more satisfying than this

@moonglum1015 2 года назад

If you use a tablet to do the puzzle then you don't even have to double-click (well, double-tap, I suppose). You can just press and hold to select all cells of the same color. It's like half the effort. It's great for lazy people like me!

@AudreyAzura 2 года назад

What I find absolutely beautiful and that Simon hints at but seems to not mention is that the pattern of knights moves and diagonals repeats for every digits. If you go from left to right and wrap the grid (if you exit from the top, you come back in at the bottom), the position of any given digit always follows the pattern: knight move - knights move - diagonal - diagonal - diagonal - diagonal - knight move - knights move From what I understand from the solve, the diagonals seem to be a consequence of the "2" regions, and the knights move from the "worm" regions. I find that really beautiful to look at, to be honest. Phistomefel is really such a genius setter.

@easternbrown 5 месяцев назад

This puzzle has some awesome geometry. One thing I noted is that the shape of the four circumferential blocks implies an equivalence between the four corner digits and the four diagonally adjacent squares within them (I found this by drawing a ring like Simon shows in another video with a Phistomefel puzzle). I also noticed that fully colouring in the three blocks present in the top two rows, then cancelling the top two rows themselves, leaves a new shape of nine squares (which must contain one full set of the digits) on the right of the grid. By comparison with the original block in the top right corner, the 2x2 square in the top right is equivalent to the 2x2 square of the 'inverted worm' shape, as Simon calls it in fhe video. I also noticed that by comparing the four circumferential blocks and then 2x9 rectangles they sit in on each side of the grid (which must contain two full sets of the digits) it's quite easy to establish some equivalences between the 1x5 strips which are in the middle of the two perimeter rows/columns on the four sides of the grid. These in turn allow some equivalences to be established between individual squares, by comparing the single rows and columns with equivalent digits in the middle five squares.

I don't really like sodoku puzzles, but I find your enjoyment while doing this videos enticing.

I love your puzzles, my first sub 2 hour solve on a phist puzzle 😁

My first attempt at a harder puzzle. I've been warming up with Mark and the GAS collection, but this is my debut at one of the beasts. Despite watching Simon solve quite a few over the past couple of months, I never thought I could manage one. I'll admit to getting stuck 3 times but with the smallest of hints from the video, I got going again. Learned some elegant techniques and enjoyed it immensely. Thanks to both Simon and Phistomefel for a cracking puzzle!

I had given up on this ... but when I came back later for one more try, I started seeing things ... then more things ... All told, I was able to finish this one in 42:43. A far cry from my last effort on a Phistomefel puzzle!

This is my favorite sudoku for sure. So fun

Why would anyone admit to taking three hours to solve this puzzle? Because that's how long it took me. And then I get another 45 minutes enjoyment watching Simon's solve. A brilliant puzzle. Thank you.

That first 6 never ruled out the seven above it. That impossible seven should never have been marked there because of the given seven . :D

20:47 you can, by Sudoku of all things. The third from top region sees a 4 everywhere but that corner, and once you place that 4, the same becomes true of the second from top region. It then rebounds to the left side to fix the 4 and 7, giving you the 4 for the right hand box in r8c9, placing the final 4 in r9c8

I managed to do this own in about an hour. When I spotted the 2 3 5 8 trick I stood up and said (yelled), “that is incredible.” - Absolutely stunned me. I had to take a break and just let it settle in my brain. This construction is beautiful.

15:00 "This *6* is ruling out a 7" Simon's brain works in mysterious ways.

Adjacent cells may not be consecutive

@deltaangelfire 2 года назад

also the fact that there was already a given 7 in the column

@Kinhoma 2 года назад

I was watching and waiting for him to find the moody complicated way of deducting that c2r5 couldn't be a 7 despite the only given 7 was just four cells below it.

:D Forgot the given 7.

Every column is the same pattern just shifted slightly. It's mesmerizing.

@Squishy3757 2 года назад

Seems you forgot for a while that 6 and 7 restricted what was next to them.

That was a fun little Eagles intro. Great vid

I noticed there was a repeating pattern at 39:11, and then stopped and filled in 4, 6, 7, and colour-coded the rest of the gird, and then I watched to 43:49, where you mentioned that 6 can't be next to three, and then I was like wait I think I can solve this, and did! Obviously I couldn't have done it without your help, but I never would have thought I could solve it at all :))
