Today's sudoku has been requested by some of our patrons on Patreon - we were pretty sure before we tried it that this was because it was HARD... And we were right! It's also very very clever - it's called Antiknight Between Line and it's by Gliperal - do give it a try at the link below:
app.crackingth...
Rules:
Normal sudoku rules apply. Cells separated by a knight's move (in chess) cannot contain the same digit. Digits on blue lines must be strictly between the digits in the circles at either end.
▶ SIMON'S WAY OF SOLVING LAST NIGHT'S MARK PUZZLE ◀
As a Patreon bonus, Simon has recorded his solve of the beautiful puzzle Mark attempted last night by Sumanta Mukherjee. Mark did an amazing job of solving it without recourse the trickery that Simon is perfectly happy to employ!
We've also released a sudoku hunt themed on The Hitchhiker's Guide To The Galaxy as our monthly Patreon reward for June. Remember that we will also be releasing a new Murder Mystery Sudoku Hunt for everybody if we reach 5000 patrons.

"I almost feel like Gliperal must have just been laughing as he set this."
You're absolutely right about that Simon! This puzzle, to me, exemplifies some of the splendor of anti-knight, how so much can be forced through geometry alone. After the break-in (the lines through the center), I had only placed a couple cells of the other between lines, when the constraint grabbed the reigns. It was all I could do just to avoid the coloring becoming trivial. Rows/columns 3 and 7 are particularly powerful with this arrangement in the center box, and having the between lines poke diagonally into boxes 3 and 7 (hitting the only cells the circles can't see by sudoku/antiknight) causes these tremendous cascades which were a lot of fun to discover.
Of course anti-knight is a fickle mistress, so those beautiful cascades ended up leaving no solutions an awful lot. I had to sacrifice symmetry in the end, in favor of a more elegant solve path. You can take either top left or bottom right between line and make the puzzle symmetric and it will still have a unique solution, but each one bypasses a lot of the ending logic.
Thanks for giving this one a go! As expected you were able to spot the anti-knight geometry tricks rather quickly, and keep the solve flowing. A fully logical solve, with minimal look-ahead (if any), and spotting almost all of the desired tricks. I couldn't ask for a better treat on a Sunday afternoon.
Thank you very much! I love knight and disjoint restraints. They permit very beautiful visually minimalistic puzzles with actually a lot of clues if we dig in.
8:54 Do r2c6 and r3c8 have to be different with each other?
sorry for my poor English,does "strictly between" mean no digits repeated on blue lines?
Thanks! I like chess Sudoku.
@@林老師-i5d Digits can repeat on a between-line puzzle, if sudoku rules allow it. They just can't *equal* either of the digits in the circles--that's the "strictly" part. But the two cells you mention see each other by knight's move, so they must be different, in this puzzle.
That was the most fun I've had following an anti-knight "cascade"...I think you put that constraint through all its possible paces. You really could't miss a single implication or elimination, or you'd be stuck staring, but the logic flowed smoothly. Well done!
@@wokkawicca got it! thanks for your explanation
Would an organ intro be of interest some day? (I´m an organist)
I don't know about Mark and Simon, but I'd love to hear it!
The more different instruments the better.
That would be amazing!
Organ donors should of course be welcome.
@@jonewhouse1222 not that type of organ you melon 🤦🏾♂️. He's obviously talking about the spice 🧐
There are two types of puzzles: those that let me getting bored and leave the video very quickly, and those that are so great that get to watch the entire video without even thinking a single second to leave it! As always, congratulations and thank you Simon for your excellent solves! Greetings from France.
PS: you're one of the person that make me speak English better 😁
New drinking game to stay hydrated in these hot temperatures, take a shot of water every time Simon says a colour!!
I like the puzzles where he has to place pentominoes, taking a drink (of water) every time he says Zed. FULLY Hydrated!
Oooh, beware of hyperhydratation! 🤣
"It's not my fault, well it is my fault, but you know what I mean?" 😂😂😂😂
Anyone else like the wry smile Simon gets when he says “lets get cracking”? Genuine joy.
Yes every time. It’s so genuine and wholesome
yes!
Here is a puzzle from Gliperal
his rules should be taken literal
His sudokus are hard
almost nuclear at heart
we measure their levels in Becquerel
Hi Simon. I have to thank you. I stumbled onto your channel a few days ago and I've been absolutely fascinated. The last two days I've been forced to stay home from work due to illness and I started doing Sudoku for the first time. I did easy ones the first day and now I'm doing medium ones in like half an hour and loving it. If it hadn't been for this channel, I never would have touched them, so thanks again.
24 Celsius is colder than what I set my thermostat to...
24C - a pleasant winter's day here :)
Impressive, most impressive. Thank you.
I think this is a great example of what Clover was talking about in her setting video: sure, there's a fair bit of logic to wade through (colouring helps) but it's not difficult for the SAKE of being difficult. Where you need to focus for the break-in is clearly signalled; once you understand the interaction of the two variants, it's approachable and satisfying. I had a lot of fun with this one.
Thanks for playing Lucy's intro these last few days. Its so pretty
It is really a wonderful version.
47:14 "Is this seeing anything?" YES!!!!! Knight's move means box 9 blues are in row 8 which gives you some blues. So much shouting! Hahahaha Love you Simon, you're way better at these puzzles than I am, the shouting is always with positive vibes :)
He always starts on a track, goes off somewhere else, and doesn’t return to it when there’s something simple to see! Of course he also sees a dozen other crazy things I would never see.
Alternatively, he can ask where blue goes in row 7.
Yes, that is something that I think nobody really gets - we shout at our screens because we are cheering for Simon to solve the puzzle, so positive vibes all the way.
@@stephenbeck7222 I think that is the most frustrating thing with Simon's solves, that he starts out with something and doesn't finish following it, or gets distracted by Big Logic when simple Sudoku is fully available. We can see the simple Sudoku right in front of us, but he sees things I can only hope to eventually be able to spot sometime this decade. But if he keeps hammering the Big Logic, maybe I will get it sometime on my own?
Well simon you think 24°c is hot.. here it's 40° in kolkata..
Many cooling thoughts to you.
95F here - couldn't get through summer w/o A/C
24 is hot here in seattle as well
42:38 - Favourite Simon quote today:
"Okay. And then what do we do next? We pause for breath, do we? And we think. And what do we think about?"
That opening Piano Intro was really pretty (I didn't realize how pretty ).
Luv it.
Always satisfying to solve a puzzle that takes Simon around an hour. Really laboured at the end, having thought I'd done all the hard work.
I enjoyed your podcast this morning ☺️
ditto!
As a resident of the southern US, I would trade anything for 24°C temperatures. Currently we are experiencing highs of approximately 35-36°C with heat indices around 37 to 38°C.
Right? I was like "24°C (~75°F) is what Floridians set their thermostats to so they don't shiver". I like mine closer to 70°F, personally, but I'd consider 24°C a very nice day for a picnic.
same here!
Took me almost 3 hours, but it was a great puzzle. The break-in was very hard to feel confident of having categorically proven, but got the 5 and worked out the rest after noticing a number can't be both larger and smaller than another :-D. Then it turned into about the wildest color-knight sudoku I've ever done. Wound up staring for 5 minutes at my orange and blue 34 pairs before I remembered there was another between-line clue.
The setters fear you and love you, Simon.
19:44 "Have we learned anything about the size of red?" Yes, I think it must be 2 or 8, because it can't be 1 or 9, but the differences between red and green must be (at least) 3 :-)
For anyone that wishes to disagree with Simon that 24C is hot. It certainly is in the UK. Our houses are designed to keep in heat and rarely have AC so 24C is plenty enough for us to start frying inside
Temperature is whatever you are used to. I grew up having -40 to +40 c so what most people call too hot or cold is a nice day for me.
The way I understand the purple digit not being on the line (I know this is pretty much what Simon was saying): starting with the yellow and red circles in the bottom left, if red5. Now even if we'd have yellow=6, since red is on the line, we must always count *down* from yellow to purple, so purplered. Since purple is on the red-green line, it must be larger than red, but we had already found that it had to be smaller, which is a contradiction.
This one tested me; it took me over an hour (over two separate sessions), but I was able to conquer this one.
Tough (but enjoyable) puzzle!
54:22 is my time. When I saw knight's move restriction, I just started colouring. This was really tricky. Interesting idea though.
“This is the worst I’ve probably ever done on this channel” Meanwhile I’m still trying to figure out the instructions.
Maybe instead of the word "strictly", "numerically" would have been better?
20:20 screaming that he didn't realize red only had two options left, and instead totally deleted the mark lol
I always remove the coloring as soon as I have matched a certain color with a certain number. For example as soon as Simon knew green is 5, in his place, I would only use normal pecil marks for 5 and uncolor all green cells. Does anybody else do it like this?
In a lot of puzzles I do. I notice that they become distracting to proper scanning or catching various rule sets
He should have replaced green with 5s the moment the yellow/green cell was bothering him.
I did that this puzzle and wished I hadn't, to be honest. I missed a lot of simple logic because I had a colour and number pair in two cells in a box/row/column but didn't realise it because I was doing sudoku on both numbers and colours. Had I left the cells as being a colour all the way through I wouldn't have had that problem.
I normally would remove the colouring. I find though I am better at spotting anti knight restrictions with colour than without. Any other puzzle type though I would remove it. Oddly I am better at spotting disjoint sets without colour.
I normally do, but in this puzzle because I had to use multiple color choice I didn't use the legacy app. I had the grid almost covered in colors before I started getting most of the digits.
every time i'm surprised at how easy you make it seem to solve difficult puzzles like this one
Took me a minute to realize it was knights move NOT the blue line rule itself that prevented repeat digits on the blue lines
Same here, at 9:00 I was wondering why the top-right blue line had to be 3 unique digits. Had Simon seen that and not said anything, or was it just a bit of luck?
Dear lord, I loved this solve. Bravissimo.
46:02 finish. Some very tricky color logic in this puzzle, but very enjoyable. I was able to figure out the last digits without using the colors, but it was definitely more of a challenge (I had previously deleted colors for finished digits).
Here's another logical way that I used for break-in:
If red < yellow, then purple < red < yellow:
we can see that it is impossible to have green < purple as green yellow, both eliminate purple from r6c5.
oh Simon it will be 25 degrees Celsius on Wednesday here in Australia. a brisk winters day.
Simon, don't go to Las Vegas if you think 24 C is hot. ;)
"No doubt this one missed 5 deduction was causing shouting." Yes, Simon. Yes it was. :)
on the heat, mid 20s I feel is where humidity starts to mean everything
a 30 at 0% is downright pleasant with a nice breeze but a 25 at 70% is horrible
At higher heat it keeps being true, I prefer 40 with low humidity to 30 with high humidity.
2:23 Naah, don't remove that Goodliffe. You could work out that red is 2 or 8, because anything else wouldn't leave enough room on the red-green line.
51:51 I must be coloring the nines... Points at a naked single 9 :D
it’s 34-degree celsius today in my country🤣
Brilliant elegant puzzle
Absolute quality, I think that's three exceptional puzzles in a row,
I've been watching the channel for about a year and I think it's more like 365 exceptional puzzles in a row 😋
When Simon removed the red pencil marks at 20:25 I was so stoked because I had seen the pressure that the 5 in box 6 put on the between line leading to the red circle, which gives you the red value in conjunction with red being on the in-between-line in box 5 and yellow not being 1 or 9. But of course, that was the only thing I saw faster than Simon did.
He completely misses the 5 knights move in box 8 but hey at least he used celsius haha
Maybe, but Fahrenheit 451 sounds better than Celsius 232.8
24ºC is cold here actually hahahahaha
The dual colour purple/green keeps reminding me of a Dutch ska band called _Doe Maar_ ...
Shouting "Screw Blue, Do Green" for 10 minutes!
@11:40 Mark: Welcome to the dark side Simon. We got cookies.
This was a great puzzle and a very entertaining video to watch even after having solved the puzzle myself.
Simon finds that purple (I'll call it pink) needs to be a 1 around the 35 min mark, although that was immediately possible after he deduced it can only be a 1 or 9 at the 20 min mark, if he had focused on where pink goes in column 7 (row 7 or 9) and subsequently box 7 (because of the x-wing). This would immediately rule out the 9 from pink and the rest of the logic would have been somewhat more straightforward without the binary high/low logic.
This was a recurring pattern in this puzzle that he would have spotted if he had focused on the antiknight constraint a bit more from the start. I appreciate he didn't though, because his thought process was very interesting without that early observation.
Just about to post this - that was the way I did it too. Follow through with started logic rather than getting side tracked onto something else.
24, crikey!! We (Ontario, Canada) were up to 40 C with the humidex last week!!
agree... 24 is beautiful!!!!
This is like me trying to solve the last half of the arrow app puzzles.
In our country we set the air conditioner at 24 °C.
We don't have the luxuries of a cool climate.
I'd melt. I am melting now and it's night time. Don't do well in heat :(
in the UK domestic air conditioners are not really a thing. We get very few days hot enough to justify installing AC units, so we just open our windows and complain about the heat!
47:55 And Simon selects, for a second time, the correct cell while claiming it can't be used....
And at 48:17 we see another way to come to the same conclusion.
These videos are very educational, proving there is more than one correct path through any Sudoku, even without bifurcation.
40:52 ... wait ... wait ... 47:56:
Found the missed 5!
First time I figuratively and happily yelled at the screen 😁
I rarely (well, how about only occasionally?) shout at Simon; but I was forcefully trying to remind him to look at the green domino in box 9 for several minutes.
Very nice puzzle! About 72 minutes for me
The 234678 pencil mark in the red circle may have been distressing Simon, but his _removal_ of it distressed me! Since it had to be at least 3 different from the green 5, it actually had to be 2 or 8, only, of course. Ahhh!
Hell yeah, 65 minutes for me, very proud to get this sudoku done cause I'm not usually good at the between lines variant and especially as my time isn't that much more than Simon's!
It seemed like several times you were misled by the colouring, either thinking that a known cell was just a possibility _or_ thinking that a possibility was a known cell. If I'm "corner-marking" colours, I always colour them with silver _as well_ (being the closest to white) to make it clear that the cell is _not_ known to be, eg, blue, but is just one of the places that blue has to be. No, this doesn't work all that well with green or yellow because they are not as distinct, but it is fine with red, orange, blue, pink, grey and black.
I do it this way too, and I note that Mark has adopted this convention too. It certainly helps identify pencilmarked colours from placed colours.
Could someone, please, start a GoFundMe to buy Simon an air conditioner?
Homes in the UK extremely rarely have air-conditioning, and there are no small aircons available that would fit in a window. For context even in southern England we often only get a handful of days during the summer of ≥ 28°C.
For those who prefer algebra at 18:30 -
Let x be the value in the red cells. Thanks to Simon's markings, we have x = 2, 3, 4, 6, 7, or 8.
If x is 6, 7, or 8, replace every cell y with 10-y, throughout the whole grid, so x is now 2, 3, or 4. The between lines will still be valid, and our eventual conclusion below about the purple cell's location will be too. Thus without loss of generality, x is 2, 3, or 4.
Let y be the value in the yellow cells, and suppose that y < x. Then x-y >= 4 because the between line that connects them has 3 cells. Rearranging the inequality, we get y x, we have x > p, meaning p is 1, 2, or 3.
Let g be the value in the green cells, and suppose that g < p. Since p and g are connected by a between line with 3 cells, we have p-g >= 4, so g p.
Now we see that x > p and g > p, so p cannot appear on a between line connecting x and g. But this is just what would happen if r6c5 were purple, so it must not be purple.
Yeah. 24c is a normal Spring day. We have AC... My wife doesn't let it get below 78f during the day (26c). If it gets under 76, she turns on the heater. 😂
LOL - 24C = a very curious definition of "hot"
For the UK 24 is hot - we don't have air conditioning in our homes here.
No, I absolutely do not forgive you for an almost hour-long video! I want to graciously thank you for an entertaining use of my hour of free time.
Very fun puzzle! I love the ones with lots of coloring :)
The rules don't disallow repeats on the between lines. As a result the two circles in the lower left of the central loop only have to differ by 3, not 4. Same for the upper right pair.
Is this a flaw in how the rules are written, or a flaw in Simon's reasoning? (asked after watching up to 14:44, maybe he figures it out later?)
To answer myself, the antiknight rule, along with regular Sudoku rules, prevents the duplication along the wrap-around lines at the ends of the central figure, so these lines must contain three distinct numbers.
@@kevinmartin7760 I was a bit surprised Simon didn't mention the anti-knight restriction prevented repeats on the between lines. He did give the appearance of just assuming they couldn't have repeats. He's usually so thorough with his explanations. Being charitable, I'd like to think he just thought it was so trivial, it didn't require any explanation. (If being uncharitable, I'd say he may have overlooked the possibility of repeats. )
Not able to scream “green 5” loud enough.
Took me two days to place my first digit, and I see that Simon got it in 20 minutes.
Perhaps a better way to explain, why purple can not be on the between line:
if it were there it would create a virtuel between line of size 8. ( and That is to long with nine numbers)
Half way through and Simon seems to be studious ignoring where purple (19) can be.
These are the ones we live for :)
24 C is 74 F, and when you said it was quite hot, I spit out my tea in laughter. I should say, I am in Phoenix and it is 116 F or 46.7 C... That is hot.
Are repeats allowed on the between lines? I followed along without discounting repeats, and coloring eventually took care of everything.
You can simple deduct that this is not possible. Trivially it is not possible in the middle box between lines. And for box 4 and 7 you can use knights move amd normal sudoku to see that it is not possible for none of the cells on the between lines
@@yonnelourens638 Good point. Knight's move does rule it out for this puzzle. I'm somewhat glad that I didn't notice that, though, because not trusting the algebra of the ring let me just plod on with coloring. Kudos to those who worked it out from the ring.
2 digit ones ruled out by box. 3 digit ones ruled out by box and knights move separation of the ends.
In general, yes, between-lines can include repeats.
In this particular puzzle, the geometry and anti-knight restriction means that they can't.
6:00 Easy way to remove the Y & P off the lines: top line shows G is in between Y & P. It can't be on the lower line where Y would be in between G & P. P can't be in between R & G on the lower line, since it is on an end on the upper line with both either greater or lower.
By "top line" I assume you mean the between line connecting r6c3 (yellow) and r3c6 (purple). Unfortunately we don't know green is on the top line at this point-we only know it's in the domino r5c4/r6c4.
wow I tried this puzzle a month and a half ago, it took me 1h 40min, so Simon should have done a very good solve. I'm eager to see it right away!
Lol 24C is hot. I live in Pattaya, Thailand - it cools down to 27C overnite - 31-32 during the day - humidity in the mid 70's - but great puzzle and solve - thx again
Usually you use orange to represent odd and blue to represent even. So when orange ended up being 3 and blue ended up being 4, I found that very satisfying 😂
Here in Brazil, 24 celsius is actually quite a pleasant temperature haha
I really don't like using solid colors for multi-cell candidates. Light grey is a good color to "cut" them with. White would be better still.
Also, this puzzle was a case in point for retiring colors once they're known and mostly placed. A handful of corner pencil marks is much less distracting than 7 red placed 2's and 4 more candidate reds. If I hadn't reclaimed the 2, 1, and 5 colors part-way, I'd have had a grid full of confusing grey-black candidates amidst a dizzying rainbow swirl of known digits.
seeing knight moves you ignore forever.....but you always get there at least
Got down to what I thought had to be a deadly pattern which I couldn't resolve until I checked the video and spotted the 7 in r8c4.
It seems to me that it would be best to retire a color after you have fully placed a digit (so you would keep the green 5s).
52:22 was glorious. Definitely a first for Simon.
@@martinepstein9826 He cleared the green 5s, however, which confused him briefly.
@@Nerdnumberone If you know green = 5 then you don't need the color green. You can just pencil mark 5 normally.
I need a little clarification on the rules. Would it be okay if you put 7 in the first circle and then 3 - 4 and the. 2 in the second circle? Or does the order have to be like on a thermometer?
No order required!
I tried to solve the puzzle thinking the blue lines and circles were all consecutive and now I feel like a fool. I’ll just stick to my killer cages and redban puzzles
"A 3 gets placed in the corner and the surrounding cells lose there "coloring"
Great solve, will someone please tell me how to get multiple colors on the same square on the website? I feel like I've tried every keyboard shortcut possible
Click the gearwheel symbol just above the numberpad & toggle "multi-colour mode" to "on"
@@nightjarflying thank you!!!
49:09 Even though we are commenting about something you missed, we are not saying that you should have done the thing you missed.
at 11:00 when Simon rules out 5 surely you can duplicate a number on the line - hence 5 to 8 might be 6,7,6 and 5 to 2 might be 3,4,3 since the three cells are not all in the same box?
ignore that - I forgot the knights move part!
@@marcosharlequin well. you answered my questions in both of those comments. I won't ignore them
Is Simon 5-ophobic?
Cold is anything below 25 C. It starts getting too hot around 42 C. 🇦🇺🇦🇺
Cold for me is below -5°C. Favourite temperature is 14°C with occasional clouds and a little breeze. 21°C is set off point for aestivation for me ...
That's just me though: I upset others during winter time by wearing short sleeves and a vest. Suppose my genetics are not calibrated temperaturewise.
Absolute nightmare, but so satisfying once solved! Took me nearly an hour and a half, wish I'd known how to wipe all colors.
Fellas, can you have any numbers between two instances of the same number?
24 celsius is hot in the UK? Wow, in the major part of Brazil that's almost cold, our hot is after 34,35 celsius...
This was just a random comment
Just wanted to send some ❤❤❤s for simon's angryness for not seeing 5 looking at r8c8 😅 please not blame him
I know want to live in the UK solely for the reasoning that 24C is considered hot. In the states, specifically west coast, summer hit 30-35C and its awful.
I was saying for almost 20 minutes (maybe not 20 minutes closer to 10 probably) about the 5 in box 9.
Not shouting because you couldn't hear me anyway. But I was thinking that one Green couldn't be five because of the Knights move constraint.
Edit* I would've never been able to get that far on my own.
24°C is quite hot? Man, you are so British.
(I know, I know - what gave it away?)
Did you just invented rubik sudoku
24 and warm? What about solving this challenge at a blazing 42 Celsius (over here)?
I was miserable at the 39°c or 102° f in salt lake city Utah USA today so your 42° c or 108° f I think is insane.
i have literally no idea how to start this one... none
