Simon would have saved a lot of time in some future deductions if he realized the 7-9 pair he wrote in at 44:57 had a 7 in row 2 staring at one of the cells. It would have immediately resolved his 8-9 pair in the green cell at r6c8.
Some brilliant mind should construct a Suduko with the following rules: 1- No explaining of the secret allowed 2- No explaining of the phistomofel ring and/or roping allowed 3- Atleast 1 ( minimum ) '3' in a corner 4- A snake that must touch itself 2 or 3 times ( but no more! ) Love the channel :)
I really appreciate it when Mark says "Let's get rid of this colour, it has served it's purpose". I think that’s cleaner than Simon’s approach. Also, I was very relieved when the "8 or 9" corner marking in box 4 got resolved--without having led to any of the incorrect deductions that were looming in my head.
At some point I decided Simon's ability to just ignore colors left hanging around the grid was a superpower I envied rather than a shortcoming that drove me bonkers. 😂
I finished in 87 minutes. This was quite an interesting ruleset. I like it. It leads to some strange logic, but satisfying logic. It took me a while to find them all, but I did it. Another way you could solve that purple is 1 at 30:06 is to ask can r3c5 be a 4 and the answer is no, due to 3 being locked into column 4 and purple becoming a 2, breaks the arrow in box 8 by giving it 124 with a 2, making it a 9. Great Puzzle!
Two hours and I made an assumption very early on that proved to be correct. I prayed several times that the assumption would hold. Now to see how to properly solve this one. lol
I don't feel so bad now. The assumption I made was that the long arrow at the bottom had to sum to 7 in box 5 because otherwise the pressure on the other arrows nearby in columns 6 and 7 would be too great. If I had colored the mirror cells, I could have seen the same logic Simon did, but at least my reasonable assumption was proven true with sound logic. Everything else I did was purely logic based. Thanks for putting my mind at ease, Simon!
Im imagining a livestream where no talking is allowed and you speedrun as many puzzles as you can .. Mark vs Simon.. anyone else think that would be fun?
Yes, it is allocated to the other arrow. And both arrows could have the same sum only if that digit could be around the circle twice. But that doesn't work, because all the 4 cells is in the same box.
Can someone explain why row 1 column 2 cant be a 9? Where does it say in the rules that the answer to the line sum cant appear on the line or that the answer of thr sum cant both be on the line and in one of the 4 cellls surrounding the circle?
r1c2 can only be a 9 if the other arrow doesn't ALSO sum to 9. Assuming at this point we already concluded the other arrow sums to 9, then r1c2 can't be a 9. If both arrows sum to 9, we need two 9s surrounding the circle, which would mean two 9s in the same box. You are right that the rules don't say this is impossible, but there's additional logic that leads to this conclusion.
42:00 The easier way to see that 1 in box 3 has be in r3c9 is that if 1 is placed in r3c8, the orange arrow's minimum sum is larger than 7 because you can't place a 2 in r3c9
At 15 min, he can prove that r3c4,c5 can’t be a 1 because the 3 cell arrow maxes out at 8 and all 3 cell arrows < 8 with different digits must have a 1. That takes the min to 1,2,6. But if the box2 yellow digit is 3, the minimum digit on the lower arrow is 4 (4+5, which is too high…) and the max is
I just adore the posh British middle-aged dad using young internet language. It is so cute and proves that age and adaptability are just in your mind. We love you, Simon! 🤗
Finished in 36:17. I'm not usually good at arrow sudokus, so having a variant on it was nice. I particularly like how the dreaded double pairs were resolved because of the arrow constraint having as many digits adding to the sums possible. Fun puzzle!
I found the rules a bit unclear... I can't tell (before watching the video) if single cell arrows means the digit on them has to show up both on the arrow and then somewhere else around the circle (though if I am reading box 1 right, that resolves the ambiguity)
Very nice, as ever from Jay Dyer. At first glance one of those puzzles where there simply doesn't seem to be enough information to solve, but, lo and behold, there is.
Simon jumps around the grid too fast when he puts in digits and misses a lot of pencil marks he could use. His brain is too fast sometimes and wants to jump to the next deduction he sees. He missed so many easy digits in a short span a time that would have made the puzzle easier.
He is doing this on purpose, otherwise he would be done in a few minutes. He doesn't want to lose his "1 hour listening and watching him speak and solve"audience.
Here's Simon doing a Thursday puzzle on Wednesday... the week before ;) That's not unusual given he has to plan days off every now and then. But either he carfully planned birthdays (recorded-ahead videos typically don't have any) or birthdays were 8 days late this time ;) As usual, thank you Simon for the company and hints as I solved the puzzle (I had to pause Simon a few times on those "ah!" moments to avoid spoilers, but those were nevertheless clues on having to figure out something in some area)
A very interesting puzzle. I’m a bit unwell today so this provided a lovely distraction as I recover. Really interesting interplay here for sure between the arrows, and Simon keenly spots relationships between them with aplomb.
I didn’t get the “sum of 2 arrows maxes out at [9+9 or 9+8]” logic that unlocked the puzzle initially but I was pleased to get most of the rest of the logic.
The point is that when arrow sums add up to a total, the arrow heads add up to that same total. So in boxes 1-3, Simon added up the minimum arrow values and the total was 18. Therefore the 2 arrow heads have to be 9+9. We don't know yet where those numbers go, but they are single cell totals so that's the only combination that will work.
What an interesting puzzle! I do wish you'd rediscover your sudoku skills. You used to be on the UK sudoku team, but today you can't do sudoku for toffee. You either don't look for, or can't see perfectly obvious digits, and your lack of rigour to ensure that the effects of each deduction are fully applied (updating all pencil-marks seen by it, checking whether it removed options for a different digit, etc.) makes your videos increasingly tedious. Your break-ins are excellent, and when you get stuck, your ability to spot difficult logic is also excellent, but as soon as you're on level ground you just go to pieces. You're like the legendary haggis that run nimbly around the highlands of Scotland, but their unequal length legs mean they can't even walk on level ground. I appreciate that you're doing live solves, so I don't expect perfection, but I'd like to see you at least strive for perfection. Your attempts to solve sudoku without using sudoku are getting tiresome. You used to apologise profusely if a video took more than 30 minutes. Granted puzzles have got harder, but not all, and it's now rare for you to have a video shorter than 30 minutes, even the easier puzzles often take you 40 minutes. Pre-COVID, most times posted in comments were significantly longer than yours, now they're often a fraction of yours. I'm sure that's because like me they've learnt from you effective strategies for breaking in, but unlike you, they haven't abandoned sudoku. I've been taken to task before for moaning at you, but I only do it because I know you're capable of much better. Congratulations on hitting 600k subs BTW.
If I had to summarize this channel: two middle aged guys enthusiastically looking for naked singles in a puzzling manner, and they're very happy when they find one, but the more complex finds they describe as "beautiful" or "gorgeous". 😂 Love you guys, I've been following the channel since the pandemic!
I am once again hoping someday Sven works out a way for us to be able to note/color/something the quad circles. My brain sticks on things I can't make notes about, and kept revisiting the same circles over and over at the beginning of this puzzle, trying to work out relationships.
This might be me being daft, but can someone just explain to me how the arrow pointing to R1C2 works? I have tried working out how that number fits with the arrow sum (just so I don't spoil it by inputting the number) I just can't seem to wrap my head around it even when reading the clues. Does it just equal itself?
I pondered on that and reread the rules and looked at the nines in r6 and r7. It states that the total of the arrow must be in the quadruple and if two totals are the same they are both in the quadruple. Well, the total of r1c2 is technically in it's quadruple. But then I thought: but the one cell arrow in r6c8 is duplicated in r7 c9 so why isn't r1c2 duplicated? But if you read the rules dry, it just says with two nine totals there should be two nines, so the one cell nine arrow could point to itself and the two cell nine arrow to the other nine. So it's ok for a one cell arrow to point to itself I guess.
My timer said two hours, but I think the timer ran in the background for about half an hour. Still, took me a really long time, I made many mistakes, I had to look at the video a few times, and I don't think I ever would have though that r6c7 was the sum of the arrow pointing up and to the right.
12:10 Surely not as much as a 7 - that would need to go with double 1, and so would make the three cells on the other arrow in box 2 no less than 234...
16:15 , that is a "peculiar arrow,'' Simon said. I would think, whatever is on that "arrow" must be around that "circle." So, I think that "arrow" has to be, itself, one of the "cells around that circle." The x-wing on "9s" still applies, I just think that arrow cell is the "9" itself. A "peculiar arrow" indeed. 😂
IN OTHER WORDS; Whatever digit you put on that "arrow" must appear "around that circle." So, I think the "arrow" itself, must be that digit. I had an "89" in there, but thanks to Simon's math, it's now the "9." I think, anyway?
I left the "9s" in three places up there (the "arrow cell" being self-referencing), so you couldn't rule out "9" being the "self-referencing" arrow cell until the very end. That's my point, I guess. "9" is not placed out of there UNTIL THE VERY END, I guess is my point. Am I wrong?? Nice puzzle..
@@no_name4796 Well, I'm using the sudokumaker app, which I believe is used by most creators. It tells you if there are any solutions to a puzzle you create, and if it is unique, as long as it can solve it somewhat quickly.
Edit: Steve's answer below is the correct answer. I lost track of my arrows. -1,2,3 appear in the box in c4, so the minimum for those two corner cells on the right are 4+5=9. Make either of them a 6, and they sum to at least 4+6=10, but you cannot have an arrow summing to a double digit number.-
r79c6 are a minimum of 4+5=9. r689c7 are a minimum of 1+3+4=8. Minimum total is 17, which is also the maximum, because the corner pencil marks in boxes 3 and 8 prevent two 9s from going around those circles.
Blind as a bat. At 45:03 he puts a 79 pair in box 3 and fails to see the 7 in r2c4. It's actually a refusal to work calmly and methodically. He's always jumping all round the grid because he thinks he's racing against the clock. I wish there was some other channel where I could see these great puzzles solved cleanly and optimally.
Love it, but since finding out you were a merchant banker, I can no longer subscribe to this channel. Some of us remember the real criminals who caused the 2008 crash. I don't follow scum.
“Oh no, this is just sudoku. This is not what I thought was going to happen I’m afraid.” 😂 Priceless!

Simon would have saved a lot of time in some future deductions if he realized the 7-9 pair he wrote in at 44:57 had a 7 in row 2 staring at one of the cells. It would have immediately resolved his 8-9 pair in the green cell at r6c8.
I’ve been saying quietly to myself, “Simon, that can’t be a 7,” repeatedly until he fixed it.
Some brilliant mind should construct a Suduko with the following rules:
1- No explaining of the secret allowed
2- No explaining of the phistomofel ring and/or roping allowed
3- Atleast 1 ( minimum ) '3' in a corner
4- A snake that must touch itself 2 or 3 times ( but no more! )
Love the channel :)
No imagining marbles/tiles in a bag
No Schneider notation needed would be fun

Simon is opposite - he will unnecessarily colour cells because he "feels bad for them" 😂
Great puzzle. Great solve by Simon. My favourite part was when he proved a cell couldn’t be 8 then proceeded to write 8 in it. Priceless!
2 hours and 56 minutes! Time consuming, mostly not too hard, couple hard points, I really liked this one!

Another way you could solve that purple is 1 at 30:06 is to ask can r3c5 be a 4 and the answer is no, due to 3 being locked into column 4 and purple becoming a 2, breaks the arrow in box 8 by giving it 124 with a 2, making it a 9. Great Puzzle!
Nice reference to Clarkson farm 🚜
what is happening with the arrow in R1C2?
I'd love to know - seems non-sensical
It's forcing the 3-cell arrow to NOT sum to R1C2
It's saying it can't be 9. I'm not sure if Simon uses that in his solve path but I did.
I have the same question, then it should have the same total around the circle? So two 3s ! Or did I miss something
55:44 what a devastating gut punch. No 3 in the corner :(

Very Easter pastel colors at the end.

Why can't the green square be the sum of the orange arrow at approx 42 mins?
It's already allocated to the southwest arrow.
Yes, it is allocated to the other arrow. And both arrows could have the same sum only if that digit could be around the circle twice. But that doesn't work, because all the 4 cells is in the same box.
Can someone explain why row 1 column 2 cant be a 9? Where does it say in the rules that the answer to the line sum cant appear on the line or that the answer of thr sum cant both be on the line and in one of the 4 cellls surrounding the circle?
r1c2 can only be a 9 if the other arrow doesn't ALSO sum to 9. Assuming at this point we already concluded the other arrow sums to 9, then r1c2 can't be a 9. If both arrows sum to 9, we need two 9s surrounding the circle, which would mean two 9s in the same box. You are right that the rules don't say this is impossible, but there's additional logic that leads to this conclusion.
Thank you! I missed the point about it having to appear the same number of times in the box.
My excuse is it's 6am Friday morning 😅

Well, this was interesting, for sure. I could never in a million years solve this, but as always, I enjoyed watching you solve it. Thanks, Simon.
42:00 The easier way to see that 1 in box 3 has be in r3c9 is that if 1 is placed in r3c8, the orange arrow's minimum sum is larger than 7 because you can't place a 2 in r3c9
At 15 min, he can prove that r3c4,c5 can’t be a 1 because the 3 cell arrow maxes out at 8 and all 3 cell arrows < 8 with different digits must have a 1. That takes the min to 1,2,6. But if the box2 yellow digit is 3, the minimum digit on the lower arrow is 4 (4+5, which is too high…) and the max is

Stunning puzzle - looking forward to this one.
btw after I solved it, it took a few moments to work out what the short arrow in box 1 had been there for ...
This might be me being daft, but can someone just explain to me how the arrow pointing to R1C2 works? I have tried working out how that number fits with the arrow sum (just so I don't spoil it by inputting the number) I just can't seem to wrap my head around it even when reading the clues.

But then I thought: but the one cell arrow in r6c8 is duplicated in r7 c9 so why isn't r1c2 duplicated? But if you read the rules dry, it just says with two nine totals there should be two nines, so the one cell nine arrow could point to itself and the two cell nine arrow to the other nine. So it's ok for a one cell arrow to point to itself I guess.
My timer said two hours, but I think the timer ran in the background for about half an hour. Still, took me a really long time, I made many mistakes, I had to look at the video a few times, and I don't think I ever would have though that r6c7 was the sum of the arrow pointing up and to the right.
The funky arrow sum says that you should try it, and it did lead to correct solution but how to prove it's the only one...comeback to watcjhe video
What brilliant setting by Jay Dyer. After solving this puzzle putting in lots of time and effort there is 100% elation and zero frustration.
Bird jump scare at 21:16 :D
14:30 I've proved this is going to be low. This is huge.
Out of context this makes no sense.
Gotta love this channel
22:45 It's not the most stupid thing anybody's ever said, ever.
That's a pretty low bar.
Very extraordinary and exciting puzzle.
You spelled wrogn wrogn in the title
26:52 for me. What an interesting idea, great puzzle!!

12:10 Surely not as much as a 7 - that would need to go with double 1, and so would make the three cells on the other arrow in box 2 no less than 234...
Already used logic in box 8 to prove that there must be a 1 on the arrow, then doesn't apply that logic to box 2... :(
16:15 , that is a "peculiar arrow,'' Simon said.
I would think, whatever is on that "arrow" must be around that "circle."
So, I think that "arrow" has to be, itself, one of the "cells around that circle."
The x-wing on "9s" still applies, I just think that arrow cell is the "9" itself.
A "peculiar arrow" indeed. 😂
IN OTHER WORDS;
Whatever digit you put on that "arrow" must appear "around that circle."
So, I think the "arrow" itself, must be that digit.
I had an "89" in there, but thanks to Simon's math, it's now the "9."
I think, anyway?
I left the "9s" in three places up there (the "arrow cell" being self-referencing), so you couldn't rule out "9" being the "self-referencing" arrow cell until the very end.
That's my point, I guess.
"9" is not placed out of there UNTIL THE VERY END, I guess is my point.
Am I wrong??
Nice puzzle..
I've created a puzzle with an unique solution but still can't solve it. Can I share it or should I be able to logically solve it first?
How do you know it has a single solution if you haven't been able to solve it?
Computer I assume
It is not hard to get such a puzzle - if you know the unique solution can you see where you might add additional clues to aid the solver?
@@no_name4796 Well, I'm using the sudokumaker app, which I believe is used by most creators. It tells you if there are any solutions to a puzzle you create, and if it is unique, as long as it can solve it somewhat quickly.

52:51 today. very hard sudoku.
at 31:07, how was 6 ruled out from r7c6?
Edit: Steve's answer below is the correct answer. I lost track of my arrows.
-1,2,3 appear in the box in c4, so the minimum for those two corner cells on the right are 4+5=9. Make either of them a 6, and they sum to at least 4+6=10, but you cannot have an arrow summing to a double digit number.-
r79c6 are a minimum of 4+5=9. r689c7 are a minimum of 1+3+4=8. Minimum total is 17, which is also the maximum, because the corner pencil marks in boxes 3 and 8 prevent two 9s from going around those circles.
Blind as a bat. At 45:03 he puts a 79 pair in box 3 and fails to see the 7 in r2c4. It's actually a refusal to work calmly and methodically. He's always jumping all round the grid because he thinks he's racing against the clock. I wish there was some other channel where I could see these great puzzles solved cleanly and optimally.
Love it, but since finding out you were a merchant banker, I can no longer subscribe to this channel. Some of us remember the real criminals who caused the 2008 crash. I don't follow scum.

@@BongoBagginsMy comment didn't mention Simon at all.
Consider he left that job that made him miserable for something he actually wanted to do.
1:07:23 ... I really need to stop trying these so late at night
Nice puzzle!
