An Extraordinary New Sudoku Rule
Ойын-сауық
** TODAY'S PUZZLE **
We've had lots of recommendations to try this sudoku from CaptZebraCakes - it's called Mislabeled Killers and we just want to say that this is a BEAUTIFUL puzzle. The logic is fresh and fascinating and, although it has a 4* rating for difficulty, it's incredibly fun to solve once you cotton on to some of the key ideas.
Play the puzzle at the link below:

Rules:
Normal sudoku rules apply. Every cage is a “killer cage” where digits cannot repeat. The two-digit pill in each cage forms a two-digit number when read from left to right, and this two-digit number represents the sum of a different killer cage (i.e. a two-digit pill value cannot be the sum of the cage that contains that pill). No two killer cages have the same sum.
(The musical intro today was inspired by watching Coldplay at Glastonbury with Michael J Fox last night.)

This is such a fantastic puzzle. Already after testing it, I was sure it had to go here. I think you have done a great job of adapting to the new ruleset and explaining the logic that comes from it, Simon. In particular, I liked your tricks with the 12 candidates. There were some logical steps I had missed in my own solve. Thanks for this great video solve! And, of course, big thanks to CaptZebraCakes for setting this gem!

It took me a while (I'm getting quicker though the more I try!), but the first important thing is that the most limited digit is the tens column of the pills. That combined with the fact cages cannot sum to 10 or 11 is suddenly interesting for the two cell cage...
I was very proud of myself that I worked out the 45 cage and the pill that had to say 45 because of the 2-cell cage that had to be 39 and so on. And I did the mapping of the digits in the 45 cage that were missing in its box as well. But all this took me already nearly 50 min (that I started last night before bed and continued this evening for a bit) and then I didn't know how to deal with all the 5-cell cages... still I had a great time with this. I am always happy when I can do a little of it without Simon's help but I still get to watch Simon solve it. When I solve it myself completely I don't usually have the patience anymore to watch Simon solve the same puzzle.
What an amazing puzzle! I was intimidated at first, thinking I could not possibly break into the logic. But after pulling out a note pad and going through ranges of sum options, the path forward came so naturally! BRAVO!
Simon "Ah.. Oh yes, ah.. um.. ah! That means...! Ah!" me: "whaaaat!?" also me: "Let him cook"
A Simon guitar intro had me hit “like” before even watching the video.
32:27 such a randomly satisfying "Ahh"
This puzzle was a fun exercise in notation. I tried a few options and settled on drawing a colored line through each pill corresponding to a colored fill of each cage.
Simon to a Puzzle: "I will tryyyyy to solve you!"
I loved this puzzle. Can't wait for Simon to love it too.
I haven't played a sudoku in years but every time I see one of this guy's videos I absolutely love it
Wow. Wow wow wow. I'm so glad that I tried this one before I watched Simon's solve. What a spectacular puzzle, and what a beautiful solve path when you go about it the right way.
40:52 my time, 2nd time in my life faster than Simon! I only saw the rules and got a thought, that I must solve it myself. Brilliant puzzle!
I am always amazed at watching these videos. You look like you have so much fun with these puzzles. I hope that one day, my logic and puzzle skills allow me to enjoy puzzles of this difficulty.
That was really neat, thanks. At first look a bit of a headscratcher, but once I got my eye in my biggest challenge was understanding my own notation for which sum related to which cage.
I finished in 127 minutes. This was a brilliant puzzle with a cool ruleset. I love the kind of logic this produced, calculating for regions elsewhere. Discovering that the 12 pill had to go in the top right corner, due to a 12 pair seeing all the others, was fantastic to see I think my favorite part was seeing that the 12 in r5c5 had to go into column 9, disambiguating that cell, leading to a massive chain of digits. I really liked this one. Great Puzzle!
Very beautiful ruleset ❤ And the puzzle is perfect. Good job Captain ❤
I was screaming about the 5 in box 5 as soon as you filled the 14 pill! Very interesting puzzle though!

There’s no way in hell I could even start a puzzle like this never mind finish it, but Simon’s abject basic sudoku towards the end was hilarious!
Beautiful puzzle, beautiful solve, topped off with Simon overcoming chromatic disappointment to clean up redundant colouring! 😉👏
OMG I cant believe the 5 in C6R4 was the absolutely last digit to be placed. It was given by basic Sudoku at 43:58. I have notice that Simon has a penchant after placing a digit to NOT scan that digit's Column, Row and Box for what falls out from the digit placement, but rather immediately has a compelling urge to look in completely unrelated areas for a unrelated New complex Logic foot holds then gets stuck for 2-3 minutes. Simon would instant be a level higher (than the obviously very high level he already is) in Sudoku solving if he only forced himself to scan Column, Row & Box after every digit placement, before going of on the next Complex Logic search.
Love watching Simon solve a puzzle like this, it makes me so happy and you feel no problems in the world when he is solving it :)
Finished in 38:12. It helps to figure out what the limits are for each cage and use that by process of elimination with the unique killer cage sum rule to figure out which pill represents which cage. Fun puzzle!
With the amount of unlabeled killer cage puzzles you do, it would be really nice to have a way to mark killer cages where the markings: 1. Sit nice and small in the corner 2. Don't disappear when you enter a digit 3. Order based on input (eg. so you can type 21).
Very neat solve! Unfortunately I had a complete spasm and mistakenly thought that the cage with the 12-pill had to add up to _more than 20_ (as Simon would say, "naughty brain!") because I knew it couldn't add up to exactly 20, and so ruled out all of the 4-cell cages as options ... and funnily enough, everything went wrong after that 😢
Teenage cages are a great idea! Both in sudoku, and for teenagers.
yet another satisfying and intelligent solve! I'm a very casual sudoku solver so this is way beyond my level of capabilities but your videos are always so fun and relaxing to watch and I understand every single solution you explain, thank you:)
The back of my head feels like its expanding or being tickled everytime I listen to his logic
53:30 - Time to be remembered. At that time Simon placed 2 consecutive digits in the grid WITHOUT mistiping!!!!🤣
42:10 Directly after founding R1C2 is 6 or bigger I saw C2 has 3x 6,7,8 and 9 and once only 7 and 8. So the 2, 7 and 8 had to be a 2.
I got stuck on this one but it made a lot of sense when I watched the video!
This new pill rule is actually really exciting. Imagine applying it to something other than killer cages, like a diagonal clue for example. There's so many possibilities
Fascinating design....looks to have 7 solutions without the given...crazy how a given can wrok a rulset. Interestinf how the cages are grouped into 7 pillset and 2pillset
Your birthday wishes and genuine personality just make my day, the puzzles are also great 😅 This is an incredible ruleset though, almost remids me of a game of Risk in a few ways.

Took a little under four hours. (Then again, I wasn't pausing while running errands.) I deduced the bottom pill and the 45 quite quickly, filled out most of the 1s and 2s, and everything was smooth from there. I finished it to the tune of "God Only Knows" and "The Other Side of the Wall". I haven't solved in a while -- this was a great puzzle to come back to.
I would not have solved this on my own but WOW what a beautiful puzzle
I found this puzzle quite enjoyable. Not actually too difficult - though I got stuck for a while after forgetting that I had to have a 1-2 pair in a cage label somewhere. 1:52:17 for me!
solved in 23:52 - very good idea. I liked trying to keep track of which cages had which totals
Lovely puzzle and great new rule set!! Wonderful guitar playing for us Simon!!
Just barely beat Simon's time, coming in at 45:06 What a marvelous puzzle!!!!!

A new rule. yes please. thank you Simon and CaptZebraCakes!
I was not expecting to see Simon playing the guitar, but it was very nice!
Took me 02:25:03. Great puzzle, very nice solutions. Took me way too long to find one digit at the end
15:44 for me. What an interesting idea, I really enjoyed this one. Fantastic puzzle!!
A fine example of GEOMETRY and LOGIC leading to a "fairly" straightforward solve. Completed in 13m17s.
Amazing puzzle! Glad I managed to solve it, despite botching the second half multiple times (as is my MO).
9.5 minutes in i'm like, that pill-is-cage one, i'm like okay, it's gotta be a 2 digit number so it's going to be like 3+something high, but it has to be at least 12 so it's two different digits... and i'm like 3+9 boom.
At 15:48 how do you deduct that the pill on the bottom left can't be more than 12? I get that it can't be less, but why not more? ................. Oh,I just got it! Cause it must start with a low digit and the unit digit can't be more than 9! Ah, the beauty of logic!
Simon decided to go cracking the Coldplay today I see 😍 a beautiful intro, a beautiful tribute to the most beautiful band 😍
I got mixed up thinking the cage in box 1 was the 14 cage, rather than the one in box 8/9. Otherwise I managed to follow the logic very well! A challenging and fun puzzle to be sure
Went for it when I saw it was featured and I hadn't solved it - maintaining the quality, I would say - great puzzle.

And I would say I was ahead on some things, but the thing that held me up was (having done all the thinking) not realising that the 23 total was the maximum for one of the cages ... That wasted me a few minutes thinking time. Simon, you are such a good solver - the clarity of your thinking (and the consistency of that) is ahead of mine
Lovely guitar!
Very cool puzzle, and not has hard as I had expected. Took me a bit over and hour even with distractions.
14:50 -- Zebra Cakes is a US pastry snack, like a Twinkie (only its not).
What a clever puzzle!
56:55, I got to the 3,9 cage in box 7 and didn't know what to do from there. Decided to watch the video long enough to be reminded that the 3,9 meant another cage summed to 39 and slapped myself on the forehead and went back to the puzzle to solve it. It was still hard and I seemed to have screwed up a lot at the end and had to undo a bit of work.

@@SonGoku-tz9vtI had to go back and redo my work, lol. It has to sum to a two digit number that shows up in a "pill" in another cage. Both those digits see each other, so it can't be a repeat (eg, 11) and can't have a 0. Those two digits, read left to right, must also be the sum of another cage. That means the "tens" digit can't be larger than a 4. Its in a two cell cage, so it's totally can't be larger than 17 (8+9). So I just worked out the numbers 12 through 17. Working backwards, things like 17 and 16 would make that cage, at a minimum, 8+9 and 7+9, which would mean the sum of another cage is 89 or 79. Way too big. So make the tens digit a 4. The biggest that could be is a 4,5, which would sum to 9, which is too small to me called out in any of the other pills. So drop the tens digit to a 3. You can get 3,9 which sums to 12, which is possible in another pill. 3,8 sums to 11, which would have a repeat. 3,7 sums to 10, which would have a zero. Anything lower would sum to a single digit number. You can try a 2 in the tens digit, but the largest it can be a 2,9, which sums to 11 (repeat), then 2,8, which sums to 10 (zero), then everything else sums too small. A 1 in the tens digit is also way too small for the sum to appear in any of the other pills. So, 3,9, in that order, is the only thing that can work there. Sorry, rambling a bit trying to remember all my logic from a few weeks ago, haha.

Very fun solve. Took me around 80mins but I wouldnt call it too difficult.

Is there a rule missing from this puzzle that states that every killer cage must have its total referred to by a pill? Simon's argument for why the 2 cell cage must be a 3 9 relies on some other cage's pill pointing to that cage, which isn't necessary from the rules as given. You could just have two pills be the same and point to the same cage that is not either of the cages containing the pills.
@moodragonx2
Ай бұрын
Yeah it's enough to say the mapping is injective or surjective, but neither is technically given. It would also be enough to say no two pills are the same, which would be enough to encompass the last rule as well (ie. replace "no two killer cages have the same sum").
@CrankyOtter
Ай бұрын
Because all cages have 1 pill and every pill indexes a cage total & no cage totals repeat, yes, functionally the rules are that each pill must reference a cage total and those totals are unique. If all pills have a cage total, and pills=cages, this does mean that there are no cages without a given pill for the total.

@@CrankyOtter No it doesn't. Cage totals cannot repeat but there's no rule that says pills cannot repeat. The rules do not identify either an injection or surjection, which would be sufficient as the other commenter stated. In the rules as stated, ignoring sudoku restrictions, you could have the pills sharing as few as two total values. 8 pills point to cage 1 and cage 1's pill points to some other cage, while every cage could still have a different value.

Do you post covers to KZread? I would be genuinely interested in listening
crazy puzzle but loved it :)❤❤❤
For this puzzle, shouldn’t there be a rule that prevents two pills indexing the same cage? As that was the assumption used to solve after filling in the 45 pill in box 2, then deleting 4 as an option in the tens position if every other pill at 17:41
Great opening serenade
For the hopefully next puzzle with these rules, use the pen tool to re-outline all the cages in different colors then color the pills to match
@AndrewMooreMar
Ай бұрын
The only downside to that is when the cells you want to outline with different colors are adjacent (like the pills on row 5). A cell border can only be colored as one type, so it ends up being a little confusing. I've thought of that approach on different previous cage puzzles, and had to step back for that reason Anyway, I still think it's a great idea, and in this particular puzzle, there would be only two troublesome cell borders

Ok, there is something I do not understand. 15:31 What is the minimum value of a pill? 12. Ok, easy. But then, that pill is a 39. Why? Why cannot the 39 go in another pill? Why cannot that pill be a 12? That would mean another cage is a 4+5+1+2, for example. I do not get it
