Rules:
In each N-by-N grid, normal N-by-N Sudoku rules apply. Overlapping cells contain the same digit eg if r6c8 is a 4 in the 9x9 grid then it is also a 4 in r1c1 of the 6x6 grid. COUNTING CARDS: A digit in a cell with a suit symbol indicates how many times that digit appears in cells with that suit symbol. Eg if r6c5 of the 9x9 grid contains a 6 then exactly 6 diamond cells in the grid must contain a 6.

Simon, I'm a big fan, having this puzzle from Michael and I being featured has given me some much needed joy ❤
Thank you, and all of the CtC community, you are ALL awesome!
This looks awesome, I have just seen the grid and I have to give this a go for myself before watching Simon!! Thank you in advance!
Loved this! 👏👏
Fabulous puzzle!!
It was quite an honor to have had the opportunity to meet Mark while in London. But I have to say, in the videos he comes across as a very clever and good-natured fellow, whereas in person, well... he's exactly that, actually. Cheers.
Lovely comment. Great that you got to meet him! (and I found him to be just the same).
Absolutely great puzzle. I enjoyed the moment around 22:00 when Simon tried to slam an 8 into a 6x6 sudoku, and then used classic harder logic to disprove it. A perfect encapsulation of a Simon video
Thanks so much for solving our sudoku(s)! And congrats to Lulero on the debut, he's made some astonishing puzzles in the past so I'm happy to see him on the channel.
There were actually four _"That's three in the corner"_ events in this puzzle.
I'm kinda disappointed at Sven for not creating those little animations which didn't make Simon sing.
Matt from the photo here - just wanted to say a huge thanks to Simon both for being so gracious and for the wonderful content on the channel. I shall leave the absolute values of our heights a mystery.
Counting circles are one of the best new rules, and this puzzle is a delight with four suits of them. Great solve!
Absolutely amazed that simon starts with the circle logic vice the fact that 7-8-9 can't go in the box 9(9x9) 6x6 section. And especially after the 1-2-3-4 quad in row 9, gives a 5-6 pair in the 6x6...
Edit: I finally get the full house reference! That you are always considering the digits in pairs! 7-8s, 5-6's
43:13
This is the second ridiculously good sudoku from Juggler I've done today. I'm blown away by what he (and Lulero) can come up with and then execute in this manner. We're very fortunate to have constructors like these, and of course Simon and Mark to help bring them to our attention.
Thank you all.
Michael and Lulero. They are two of a kind, working on Full House.
"Hello Marverick my old friend". I laughed so hard!
Ditto
Heeey this is the first time I've done a puzzle BEFORE it appeared on the channel, I was the second person to test this ☺️
where did you find it before it came here? I would like to see a repository of puzzles, but sven's app is empty... =(
I really didn't have time for a long video yesterday, and when I saw that it was multiple interlocking grids I felt that it would just be a pencil-marking festival and probably not all that interesting. But because I am such a fan of CtC and never want to miss a video, I did tune in - and kept watching as long as I could! It was so interesting (and not a pencil-marking festival) how the card counting part of it worked. Thanks so much, Simon, for doing this puzzle - it was very fun. (I had to come back today to finish up, but I was very glad to do so!)
This is my new favourite puzzle. It took just over an hour to solve and it ticked my brain just right!
“We’re going to change tack altogether. Let’s go to clubs.” Simon!
Today is the happiest day of my week for the first time in my life I’ve managed to beat your time at a sudoku puzzle. I feel really smart all of a sudden
Missed the 3 in the corner on the lowest sudoku which is also in the corner on the rightmost. The lowest has 2 3’s in the corner. And the 2nd lowest has a 3 in the corner.
I just spent over 20 minutes pencil marking, and then hit an unsolvable deadly pattern. Yay. Time to almost completely start over.
Update: I’ve figured out my problem, I skipped over a cell that could’ve been a 1 or 2.
Second update: Persistence pays off. 1:31:10. Finally done. Incredible puzzle, beautiful logic, would love to see another sometime.
I find it so funny that Mark gets rid of colours the second there is no use for them. Whereas Simon makes sure to extend the colours to all applicable cells, even if the puzzle is finished 😂
Incredible puzzle, wonderful solve. ❤️
Interesting how Simon refused to consider small digits in the ♦ suit for such a long time ... I attacked the suit the other way round, starting with 1,2,3,4s in the small grids, then moving up to 5,6s in the middle grid before moving on to 7,8s in the large grid. A fascinating extension of the circle rule, which I was very pleased to finish in just under an hour 👍🏻
Absolutely brilliant concept and execution from Lulero and Juggler, very cool use of the circle counting idea, and it tickled me that there were only three hearts haha. I had the pleasure of meeting Michael in person this week too while he was in London - what a lovely chap!
Thanks, that's quite a compliment coming from the constructor who invented counting circles! And yeah it was great seeing you in person :)
This is another one of those puzzles which was produced by two artists who merely function as conduits for the Eternal source of Wisdom. We are living in a very magical time, when these artwork logic puzzles can reach a big audience worldwide... That has never happened before.
28:30 "Nine is never on a diamond ... and that means nine is never on a diamond."
Knowledge bomb!!
A way to crack the 12s that doesn't require coloring the whole grid - the logic Simon noticed on the diamonds can be worked relatively locally in the 4x4s to show they must be different, which places a 2 in the remaining diamond in the 6x6/9x9, which then runs through the grid
yep that's how I did it
you had 3 threes in corners and you didn't sing for any of them!
Once you find that the 2s 4x4 and 6x6 have ALL the 1234 in diamons, you put all the 5 and 6 in the diamonds in the 9x9. A bit of coloring later you get which one need to be 5 or 6.
This puzzle is amazing how it fells like diferents puzzles together, pairing 12 - 34 - 56 - 78
1:07:42 for me. This one was one of my favourite puzzles in recent memory. Such smooth logic. The next step always felt fluid and well highlighted.
Looking back, I notice that as soon as I figured out that both 1 and 2 had diamonds, I had enough information to place every 7 and 8 in the grid. But of course, I was focused on the smaller grids at that point.
Simon singing Simon and Garfunkel seems so obvious. I didn't knew I needed that but here we are.
Love the content. It got me into Sudoku and Nurikabe. Thanks for that :)
This was a very fun puzzle! And my time was actually close to Simon's, for a change! I enjoyed the back and forth of switching between grids and suits, trying to fit all the clues together in a single solution. 😄
55:21 finish. This was such an amazing puzzle, with logic that wasn't too difficult but still involved. Fun fun fun!
Wow what an amazing puzzle. Loved the solve and the construction 🙂🙂
Simon: I haven’t got a Scooby Doo.
Me: Ruh roh
Simon: “I’m allowed to do sudoku.” Simon never wants to do sudoku in a sudoku puzzle and is usually very indignant at having to do so 😂
01:09:39 for me. That was a great puzzle! Loved the logic. Very much a color - erase - recolor puzzle for me. Kind comment.
Magnificent. Thank you.😀
I loved the 4 overlapping puzzles
35:24 "Although maybe I can work out where it goes."
35:36 "I'm not sure."
The amount I wanted to yell through my screen, I swear...
(Haven't gotten past this point, but box 1 eliminates R3, box 6 eliminates C8, and box 9 eliminates C7, leaving R1C9 and R2C9. Since the latter is already filled, that's a 78 pair in the corner~)
53:32 for me. Looked far more daunting than it was in the end. I did initially look at it and wonder if it was going to be too tough for me. The key was definitely working out how many diamonds had to contain low numbers in the small sudokus. Once that breakthrough was made, it felt like there was always progress to be found, so long as you remained patient.
Finished in 60:54. Interesting concept of multiple circle sets across multiple overlapping sudokus. Took a while to figure out how to approach it, but once I got the break-in, it was a joy to think of the next logic to progress the puzzle.
Fun puzzle!
Really great puzzle. im a bit surprised at how different our solve paths were. i started with all the small digits and grids while simon started with the big ones. Here's my solve path: if you apply the logic at 1:02:35 at 24:30, you get to know that there are 1 and 2 diamonds and know approximately where they are. then all of the other diamonds in the 4x4 grids have to be 3s and 4s, plus 2 in box 4 of the 6x6 that's all of the 3s and 4s. because you have 1-4s in diamonds, you can't have 2+ missing digits to equal 9, so 9 isn't in diamonds. i still had to go through the logic with the 7s and 8s, but i did have a lot less options for the diamonds
Amazing puzzle, though an absolute beast for my skill level. Got there in the end.
No apologies needed for the time taken. It was time well spent. Great solve as always.
as soon as a saw this grid my first thought was the overlapping 6 and 9 grid thinking. "well 789 can't be in the 6 grid so they must be in the line right next to the 6 grid in box 9. simon just ignores that for like 25 minutes
another brilliant one, loved it. And it's different from others we've seen
58:20 Those clubs seem to all have a very strict door policy 😂
Happy new month to you Mark amd Simon a happy summer and a summer with much amd more sudoku adventures 😊😊😊🇬🇷🇬🇧🇬🇷🇬🇧🎶🎶🎶🎸🎸
1:06:19 One tricky but cool thing I noticed here - right now there are two placed 4♦s. But box 3 of the 6x6 must have a 4♦as well, which means there can only be one more. But r2c2 of the black 4x4 and r3c3 of the red 4x4 must be the same via weird grid-spanning entangled pairs, and if they were 4♦s we'd have one too many! Therefore those two must both be 3♦s and the last 4♦must be in r3-4c1 of the red 2x2.
Just over 1 hour for me following along with Simon and still got it wrong 😂
Great solve, as always, Simon. I can always tell when you are totally absorbed in the solve when you ignore 'Maverick' flying past your window. It happened at least twice in that solve, I think.
Simon's puzzle solving intelligence blows my mind... this one was way too hard for me lol. I got the 4 in the spades as my first digit and that was it lol 1:05:00 !
I'm always surprised by how tall Simon is.
Just a quick hint - I think it would have helped Simon a ton - The Very First thing I did was use the pen tool to draw in the perimeter lines for each Grid!
way I removed 9 from the diamond around 24:50.
three 1-2 diamonds are at r3c1 of red3x2, r3c1 of black2x2, and one of in c1 of red2x2
which forces all the remaining diamonds not 1-2. and therefore all the diamonds in box4 of red2x3 is 3456 quad.
with 123456 forced only possible 36 combination is 7-8 pair
edit: noticed Simon actually uses it at 1:02:42
simon at 1:12:25 saying he is running out of sudoku. meanwhile there is an empty square in box 2 that has to have a 6 in it. and with 6 placement in box 7 would give him the 6 in the middle box
It's weird to me that Simon handled the diamonds exactly the opposite to me. I saw almost immediately that 1 and 2 were in diamonds, and I knew approximately where they were. Very quickly, I then saw that 3 and 4 had to be in diamonds and saw approximately where they were. So, the 9 was missing. Only then did i work on the higher digits. I wonder which way the setter intended? (I think mine, since it was so easily clear, but I'm obviously biased.)

wow simon is somehow quite a bit taller than I thought despite me never actually having thought about whether he is tall or not
great fun puzzle, not too hard but definitely exhausting
I wish that @45:00 when Simon placed the diamond 5s and 6s that he realized it broke the possibility of there being a 6 in clubs making the club digits be 1, 2, 3, & 4.
When figuring out the spades at the very beginning, it almost drove me insane that Simon didn't fill in the obvious 4 in the 6x6 puzzle. :) I waited. And I waited... It took an hour!
One for the books: It took Simon over an hour to work out there was a 4 in the corner of the 6x6. That was the first digit I found.
I am always surprised how sophisticated the software is that it allows for the weirdest variants.
DIAMONDED
I'm too busy today, I'm just going to watch. Good luck Simon.
This was amazing fun.
I've been waiting for a setter to create a puzzle with 4 3s in the corners. And while Simon didn't sing for any of them there are actually 4 3s in the corners of this puzzle!!!
31:40 for me. Very nice puzzle!!
That was fun! Took me 135m
Ah come on, the top right 4 was sooo obvious 😂
Wonderful puzzle, final time was 112:06 which did include a break, and was heartbroken when I found out I had made a sudoku error after thinking I had solved it at around the 90 min mark.
1:04:32 I suppose the 34 par in col 4 of the 6x6 is a decent place to look.
12:06 Simon mentioned one of the two diamonds in column 1 in the left 4 box Sudoku had to include a 1 or a 2. Simon could have eliminated 9's being in diamonds by the fact that there were three 1 and 2' diamonds, so it could not be missing 8's, instead of the more difficult way (adding to 3 is much easier, about a second) then how SImon did it, which took him 15 minutes.
When putting the 34s in spades, you can go one step further-there are three sudoku boxes with two spades and one with just one; each of the paired spades will have to be one 3 and one 4, which gives 3/3 threes 3/4 fours, therefore the lone spade in r1c6 of the 6x6 must be the fourth 4 (alternately you can do similar with a mix of rows and columns)... :edit: Better late than never
This bothered me as soon as he marked the 3s and 4s.
He sees that about an hour into the puzzle.
I needed around one hour to find out the hearts even I reduced the options of other fields by the same way you and I found the hearts numbers.
But the first spade I got after two minutes in the R1C6 of the 6x6-square.
Totally I needed 220 minutes and a few seconds.
70:09, the logic just flowed directly, had a hard time scanning everything, especially where the grids overlap. At least I didn't assume digits in the same row/column, but in different grids, we're conflicting!
5:02:59 probably the hardest ctc puzzle I've ever solved
Oof, that was a workout. 103:05 for me. Great puzzle. :)
I realised around 32:20 that column 9 had only one diamond. I think you could use this to roughly place the final undiamonded 7/8 and skip some of the more complicated logic, but I'm not sure
You’re focusing on 7/8 boxes but don’t forget rows and columns.
At 11:45, Simon can place a 4 in r1c6 of the red 6x6 grid immediately
22:10 Simon wants to place an 8 in the 6x6 grid...
i want Simon to do a "sound of silence" cover named "sound of maverick" now
83 mins for me. Mobile version!
Im kinda thinking that there needs to be a puzzle that explains its rules with exampples like this but then the solution hinges on the obvious assumption that the given example is obviously just an example, therefore naturally it cant be the true solution.
I dont think I've ever seen a ruleset where this comes into play but it would be so funny, even with a given additional hint.
You don't even need to check the sudoku logic for the 8 8s for the diamonds, all you have to see is that if you were to have 8 diamonded diamonds (lol) you'd have to put an 8 in the 6x6 which can't exist, which means IF 9s are in diamonds, you're missing 8s and 1s from diamonds but you also can't put 7s on diamonds either if you put 9s on diamonds
Either you’re very tall or Helen and Matt are short. Nice to meet fans in the wild.
I can now empathize with Simon's recurring paranoia when counting circles/suits... as I counted 32 diamonds instead of 36 so this puzzle took me 159:10 🤦♂
Happy Canada Day.
Easier way to see thing thing with the 7s and 8s in the top-right around 32:00: column 9 has an undiamonded 7 or 8.
How old are the planes?"
There is a guy who flies WWII bombers near where I grew up.
His name is Evan Fagen.
hi simon, you have inspired me to start doing sudoku setting and a few weeks ago i actually submitted my first ever sudoku
you could link the 9x9 in the 5x5's rules and add a note that explains the relationship between them
59:06 for me. could have been 10 minutes shorter, but i had to recheck the solve as i thought i made a mistake which i did not. i made a mistake thinking i made a mistake.
It took me quite a long time because I had problems with the graphics (the pencil marks are very tiny). Otherwise a nice puzzle.
I'm struggling to start because the instructions in the puzzle aren't the same as the instructions in the video. And I don't know if the counting cards rule is global to all puzzles (meaning there are only 6 diamonds across all 4 sudokus) or if it's unique to each grid.
It is meant to be global (if you still needed that, nevermind otherwise!)
@@Kenadian thank you!!
32 mins in.. in the 9x9 grid. Can row 7 column 7 be an 8?. I think the answer is no as where would you put the 7 you need in box 2?.. well im completely wrong. I think i was basing an assumption. Sorry 😮
Wow, this looks very cool. Won't be long before we have a solitaire style ruleset 😂
hooray! it only took me 07:33:21!
3 in the corner .. song. Twice lol
wonder how long until you realide you actually don't have 6 diamonded 6s despite saying you do
Not sure if this applies to the exact point you're thinking of, but at least some of the time he was counting a 6 diamond in box 4 of the 6x6 grid, even though he didn't know it's precise location in the box.
@@RichSmith77 ah makes sense
