Today we feature one of the best puzzles we have ever seen. It's called Squares And Circles and it's a debut on the channel for Burning Curtains. It makes Simon laugh in admiration of its genius. Give it a try at the following link:
app.crackingthecryptic.com/su...
Rules:
Normal sudoku rules apply. Digits cannot repeat within a cage. The digits in each cage sum to a square number (eg 0, 1, 4, 9...). Cells separated by a white dot must contain consecutive digits. There are 9 hidden zeros in the grid, which count as 0 for the purposes of cage sums and white dots. The hidden zeros appear once in each row, column and 3x3 box and consist of all the digits 1-9 once each. Hidden zeros may not repeat within a cage.
Sam Cappleman-Lynes has made an extremely clever 6x6x6 set of puzzles. We have released a solution video for this puzzle on Patreon and you can try to solve it yourself at these links (one to our software, one to penpa (which allows you to increase the size of the grids):

love how simon completely forgot that the hidden 0 also apply to cropki dots and still solved it. could have known way earlier that there is a bad digit in the 6 cell cage in row 2 once you have the 36 on one side of the kropki in box1, cause if the other side would be a bad digit it needs a 1 on the kropki, so it can't be a bad digit and the bad digit needs to be in the rest of row 2 aka the 6 cell cage. on the other kropki dots you can apply similar logic.

@simonc8785 2 жыл бұрын

Yes, once you realise that r2c1 can't be a two, because it would have to be paired on the white dot with a 1 (and can't be), it reduces the possibilities for r2c1c2 to either 4/3 or 5/6, leaving a much more manageable six combinations for r2c1c2c3 and forcing the hidden zero into the six cage. Four of those six combinations can be ruled out fairly quickly, one because the hidden zero means that the six cell cage can no longer sum to 36 and the others because the digit that would have to be the hidden zero either already exists in the row or has already been determined to be a hidden zero elsewhere. The result is that the six cell cage must be a 25 made up of 23479 with the additional hidden zero digit being either 1 or 8. This also fixes the digits in r2c1c2 as being 5 and 6 and removes 9 as a possibility from r2c3.

I paused at 6:31, to me the obvious path seems to be boxes 1, 4, and 7. Each consists of a full box (45) containing full cages. So, after eliminating a single digit from the total, there must be a limited number of ways of adding 3 perfect squares and getting a number between 36 and 44 (inclusive). I'm still working through the combinations, but my guess is that there will be two different ways of doing it with 2 cages, and probably only 1 way with 3. 36+1 (0=8), 36+4 (0=5), 25+16(0=4) are the only 3 options I see for boxes 4 and 7. And 36+1 isn't an option since there are no 2 cell cages to put a 18 pair or one cells to put a lone 1. So, box 4 needs to put 1,3,5 in the 3 cell cage and the 5 is the 0. That leaves box 7 to be 25+16(0=4). Box 1 might have more options, but the only one I've found so far is 9+9+25(0=2), but I have a lot more to check. If Simon doesn't jot these combos down on scratch paper, I will be really jealous of his memory.

Your spoiler was correct - I was stunned! There was some nice logic to start with (spotting the joker 9 in the middle, then the joker 5 and 4 in boxes 4 and 7), then I got some digits but got stuck. I gambled on the joker 2 in box 1 to be in the corner and succeeded. My final time was 78:12 which is a little longer than this video, so not such a big disappointment for me since I usually don't even try the 1 hour video puzzles! Edit: Simon explained it at 44:40 very well why my 'gambling' was correct. Pretty easy to understand.

Well I almost solved it! Left out an option (the correct one) in row two and lacked too much confidence to restart fully after it broke. Instead looked at end of video to spot the misplaced number and was able to backtrack and figure out where I'd skipped analyzing one of the permutations. Happily turned out that leaving the options open at that point didn't affect the ensuing logic I'd already done at all, and was able to finish from there. Once again pleasantly surprised. Some of these puzzles feel like brick walls to me, but a lot of the longer ones recently have been surprisingly yielding once you poke enough at the right spots. Thanks for the puzzle.

Having deduced box 8 had a 3 as its zero digit and a 1 with a 2 or 5 in the two cells outside the 36 cage before doing much in box 3, it gave me a much quicker run home than Simon yet his ability to always find a breakthrough in relatively fast time means I can never get close to his overall times. And I'm not doing it being recorded and explaining as I go! Amazing.

On the first day i got a digit, on the second i found the rest of the logic in boxes 1,2,3,5,7... three days it took to complete. The software logged my total time at 130min, but that doesn't include all the time not being able to stop thinking about this puzzle. Incredible stuff! Don't know what's more impressive - the puzzle or Simon completing the naughty list without getting actually stuck even once. One of the best CtC videos ever.

That was brilliant loved every bit of it. My favourite part I think is the hidden 7. That box is a square either way.

Hello and thank you very much for this brainshaking moment! I'm affraid you did lost me during the rules reading :) but I pushed myself to stay. And on top of that, thank you soo much to speak a perfect english with a proper accent that even a frenchman can understand! thank you :)

75 minute video and the rules consist of "hidden 0's"? Yeah I think I'll just watch the solve 😂

@TrueLink00 2 жыл бұрын

I loved watching you solve this! It’s too bad that none of the white dots were a 0/1 adjacency, as the rules allowed for that. Although, if it wasn’t towards the end, that coils have broken the puzzle by having too many options.

Practicing all these puzzles has made me a lot better at this. This one took me about three hours, one of the fastest I've done one of the hardest ones, and I agree with the assessment that this is just magnificent. What I really ought to practice is my sudoku because I spent about a third of my time on that, the other two thirds being split between the first three columns, then the stuff in boxes 2,3 and 6.

I managed it with not *too* much from Simon, but with a lot of note-taking and Python-writing. :) I used colors to indicate what sums the various boxes could total to, used 0s as pencilmarks, and red circles to indicate the fake numbers once I'd filled them in. Phew!

How on Earth did someone manage to compose this puzzle. Absolutely loved the square number + hidden zero logic, I hope to see more puzzles like this. Given there's a 0 in the example of squares, one could think that somewhere there could have been a lone hidden zero cage,.

Yes, I am stunned by this puzzle. Stunned as in absolutely not having any clue how to start this one. The Hidden Zero rule each time ruins any break-in attempt.

Great puzzle. I got to making the 1-4 pairs in the center area and then decided my night would be more productive sitting back and watching Simon's solve.

@andrewcook8093 2 жыл бұрын

I definitely think this variant should be called “noughty sudoku”. Though, I’ve been toying with the idea if using actual zeros in a sudoku with arrows and/or cages. Also, I wonder if you could pair zeros with actual schrodinger cells, though possibly that is just too crazy.

@andrewnelson2525 2 жыл бұрын

A brain-burner. I started off making steady progress, got bogged down in the middle, then raced through the final third so quickly I worried I'd missed something. There was definitely a hard hill to climb in the top three boxes, by the end of which the hidden zero logic was so ingrained the rest came smoothly. I was also able to solve all five GAS puzzles while watching Simon's solve on the second screen. I might have missed some of his more elegant logic as a result, but I gotta multi-task, or I'll never have time for anything but sudoku!

@cptroot 2 жыл бұрын

I'm so glad I decided to attempt this one. It did take me almost twice as long as Simon, but I got there in the end. I just wish I could have seen all of the more elegant approaches Simon found, rather than writing out all of the possibilities like I did :p

What I find most extraordinary is the size of his working, and the speed and accuracy of his mental math. I know what he is doing, but I would have had to write down the different square permutations with zeros a head of time as a reference. If I had to do it in my head it would have taken me days.
