Things Are REALLY Wrogn In The Sudoku Fogn!

[@patrickgass787]

ViKingPrime checking in here. This is going to be difficult to fit into a single KZbin comment but I am going to do my best. Simon - thank you. You've featured a few of my puzzles now and without exception, they have all seemed to fill you with a certain trepidation. And yet... and yet you persevere. Clover (for those who aren't aware, an absolute genius and pillar of the puzzle setting community) has said in multiple interviews, that their favourite puzzles are those where they feel like they're sympatico with the setter, in lock-step, understanding what the setter is trying to communicate. Often times it feels like my own puzzles fall on deaf ears, so contrary are they, so anathema to what many people think a Sudoku puzzle could or should be. The fact that you are willing to step outside your comfort zone, that you are willing to endure the discomfort and uncertainty that I'm told tends to come with my puzzles, and to finally arrive at some kind of understanding with these... it means a tremendous amount to me personally. Its just such a wonderful sensation, to feel like you're being heard. Some day I would like to be able to say I've set a puzzle with the same kind of brilliance, elegance and simplicity of the Aad van de Weterings and Florian Wartmanns of the world; I will continue to work on the craft but for now, I will simply say again, thank you. Amazing solve, you hit all the elements I wanted to highlight in almost exactly the same order as intended. Truly well done.

[@davidrattner9]

Just absolutely phenomenal and wonderful from you!! Would love to know how you set this!!

[@martysears]

Mate please keep on making the kind of puzzles you love to make and are really great at… I think it’s lovely that you’ve got your own style that is so distinctive. Have definitely seen you do some more ‘simple and elegant’ puzzles too, but some of the gems you plant in these more complex ones have their own kind of elegance and beauty, and it’s in this kind of puzzle that your personality really shines through 🙌🏻

[@NinjarioPicmin]

You can be so proud to make puzzles like these. Let me tell you I absolutely loved every second of solving it, this was such a treat. You packed so many clever things in there that I was smiling and laughing with joy discovering all of them

[@ericpraline1302]

Anyone would be proud of designing a puzzle of this quality.

[@agitatorjr]

This was great. I'm somewhat of a novice and I found this incredibly challenging, but solvable. Took me about an hour and a half.

[@emmkestrel442]

I think I noticed why fog of war is really nice; even if the logic is difficult to figure out you can be pretty certain that you're not looking in the wrong place.

Hey, I had a small remark for the Dark Mode of the website, I noticed multiple times that Dark Mode reverses the color of Kropki dots, it made me struggle a lot at the beginning (consecutive dots are black, 2:1 ratio dots are white in Dark Mode), so if you want feedback on the beta version of your Dark Mode, I would say Kropki dots in Dark Mode can be confusing.

[@bbgun061]

That's a problem.

[@dengale]

Even though a circle can be a lie, the digits in the lying circle are still in a circle. I was not able to grasp this on my own. Thank you

Looking forward to seeing a Kropki/Phistomefel Ring crossover! Coming soon to a sudoku based youtube channel near you

[@patrickgass787]

I hate to say it but someone is already way ahead of you (e.g. Marty Sears)

[@reidakted4416]

~@38:00, you can prove the two cells in the 6 cage have to add to 5 using your secret. The digits in box 5 have to sum to 45, and you know that 3 of the cells already add to 10 (the Schrodinger 5, the actual 5, and the zero). We also know that the 6 cage cannot include a 6789, (the zero cannot repeat in row 6 or box 5) which means the four cells outside the 6 cage are a 6789 quad, and add to 30. So to get to 45, the portion of the 6 cage in box 5 must equal 5.

[@ShardyRedVH]

I usually only attempt puzzles that take Mark and Simon less than an hour to solve. This puzzle looked so interesting I had to give it a try... and it reminded me why I only stick to the simpler puzzles lol I couldn't wrap my head around the rules to save my life; I kept going in circles on R4C4, convincing myself that I could use the 1 to make the whisper true. I'll have to come back to it another day when I have a few more wrinkles on the ol' noggin.

[@reidakted4416]

"To Schrodinger this, you'd need two ones in a cell, and that's just nonsense." Truer words were never spoken. 😆

[@annaherbst8670]

So much fun!!! Except for the three separate times I put the wrong number in and needed Simon or the fog to correct me. But it's pretty cool actually when you put a number in and it doesn't clear fog and I have to look outside the box

[@MaierFlorian]

[@zeam-h3133]

Wow this is one of my favourites. Zeroes and Schrödinger really making you think in brand new ways but it still feels truly like sudoku

[@Cid0484]

I simultaneously love the concept of Schrödinger cells and hate the them at the same time, because I keep forgetting them during the puzzle all the time. I guess that is just in the spirit of Schrödinger 😄

[@Qazqi]

The video length is daunting, but I gave it a try and it's actually pretty reasonable compared to what I expected. I think the Schrödinger ruleset has settled in enough that I didn't fumble it as often on this puzzle, so that helped, but the puzzle maintained a pretty good difficulty where I was often paused, but never really hard stuck.

[@lukamiler5824]

I was stuck for so long on 1:24:20 because I didn't realize that one of the three MUST be wrong, I thought that 2 of the 3 were definitely correct and the third is to be ignored. Nice puzzle though, I enjoyed it a lot.

[@windybeach2184]

I loved the flow of this but became stumped by those circled digits. I’m glad that Simon made sense of it for us at 52:00 😊

[@ffets-SEP]

I can follow along easily, all steps are logic, but I didn't try to solve this one, because I didn't want to turn my brain into a knotted mess, with all those Schrödinger Cells and stuff. Normally, I takes me about 3 times as long as Simon to solve the puzzles, sometimes I've got to grab a slight hint from him to carry on. Unless he gets stuck somewhere, which happens rarely in my eyes. So, big thanks to Simon for all his puzzles. And ofc Mark too.

[@bossdoorpodcast]

Jeez what a head scratcher of a puzzle. Staring at a circle for 10 minutes wondering what a Schrodinger circle means. I enjoyed the puzzle a lot still.

[@martysears]

Wow, what a puzzle and what a solve! This has got to be one of ViKingPrime's greatest works, (and there are a lot of other brilliant contenders!) Whatsmore, this is probably the most quintessentially ViKingPrime puzzle that could possibly exist... a wonderful showcase of the sort of intricate logical trails (especially involving lying clues) that he does so well and have become his trademark. I think I'm right in saying this is one of the puzzles he feels most proud of, so I'm really happy it got featured. The opening was genius, combining Vs and German Whispers in that way, which have such fundamentally incompatible logic. Great idea. And yes I loved the orange train tracks, and the moment it's revealed that they only differ in one place. The two silly 15 cages also made me giggle. Lovely stuff VKP!

[@chocolateboy300]

I got 211 minutes. I don't usually click on longer puzzles but fog of wars always give good focus. I got really confused when the first circles appeared as I knew before the puzzle started that it had to be twos. However, I had a breakthrough moment when I realized that the fake circle may include numbers that in itself don't contribute to the circles clue. It reminded me of King Crimson's ability from JJBA, where he can obliterate time for himself while events still play out, much like these circles clues where two is still contributing to the circle while it removes itself from contributing to other circles. How fun! I, then, made a stupid error and forgot that r1c3 was forced to be a 10 and kept trying to see why 3 was a possibility in r2c3. Of course, that would have made r1c3 seven, which would break the orange line. After that, it was very smooth to the finish.

[@frankjiang1857]

Finished in 47:24. The circle clue was kind of confusing as I couldn't make heads or tails of it since it was paired with a correct X clue. But I finally figured out what it meant for the circle clue to be "correct." I'm not sure if there's a way to reword it to make it clearer without giving away the puzzle there.... Fun puzzle!

[@penningmeestercgkdelft9159]

Yes, Fog of War and Sudoku combined :-) That's been a mad but beautiful solve to watch! The orange/green colours of the Dutch and German whisper lines are very difficult to distinguish due to colourblindness, but fortunately Simon always clearly explains what he is doing.

[@emdiar6588]

As FoW puzzles evolve, they are getting much more challenging. I love it.

[@sirgeremiah]

Man, this one kicked my butt. It took me a long time - and a lot of mental effort - to avoid using rules when I didn't know if they were "real" or not.

[@mikepictor]

I would have stared at the 3 circles until the heat death of the universe without ever realizing that conclusion. Well done.

[@simsplayer9952]

I was confused about it at first. I remember that there were only 3 of them. So the 2 correct ones are 2s. The other 1 is anything besides 1.

[@MjDiabolo]

Well that is not what happens in the puzzle, thats the confusing part :D Was the only time i had to look for help while solving@@simsplayer9952

[@CrankyOtter]

It’s not clear to me by 55:47 that there are only 3 circles because 3 circle *clues* could use more than 3 circles. But at the top, the 951 can’t be 950 & the 1 has to clear away from the 1 in the 6 killer.

[@bluerizlagirl]

18:13 The German Whispers lines continue off to each side. At least one of them is valid. If you go 5-0-[2,3] or 5-0-[1,4] then you now have a German whisper line with a 5, a 0 and a Schrödinger cell on it, which has to continue beyond a 5; yet both the "trick" cells that would make that possible -- the 0 and the S-cell, which could add to 10 or more -- have already been used. So only one of the Vs in the row is correct, and R5C5 must be 5, [1,4] or [2,3].

[@minamagdy4126]

He actually sees this starting around 32:40

[@denisdodelin-m1e]

But after the schrodinger '5', you still need a 0 or a 5, which is not available... My conclusion was that the R5C5 is the schrodinger cell. May be explanation to come. I'll continue watching the video.

[@denisdodelin-m1e]

Ok, got it at 58:00, when the fog vanished. Lovely puzzle and clever Simon. ^⁠_⁠^

[@MarkBennet10001]

"so easy to make a mistake" - indeed it was in my solve. What a puzzle!

[@onijester56]

The software solves it by having a solution listed, describing the filled cells. The pencil-mark cells are left blank in the "solve", and as pencil-marks are read as blank cells when you click "check".

[@eddieharwood7788]

Wow that was magnificent, and surprisingly doable. It's just so hard to remember all the connotations, in particular I tended to forget the 0 when looking along lines. But it all came out smoothly. In little bits of it I was actually faster than Simon, but he is so solid.

[@davidrattner9]

Truly remarkable solve from you Simon!!! Loved how you deduced everything!! What a puzzle from you ViKingPrime!!

[@blacklistnr1]

I disagree, I think it makes more sense to pronounce gif like gif. But at least we both agree that pronouncing it like gif is just mad

[@unexpectedparolemadwerewol6565]

From what I recall, gif is an acronym. And the creator claims the g in gif sound is Not the g sound in the word it abbreviates. So if it abbreviated guage, then it would be jif. Which frankly I believe is incorrect.

[@nerdygirltaylor]

I want to dislike this but I can't

[@RichSmith77]

I prefer the version that isn't a homophone of jif, since it's clear then that it must be spelled with a G rather than a J, when you hear it spoken. (I'm aware the creator insists otherwise. This mildly annoys me.)

[@jdkemsley7628]

Lovely video as always, thanks Simon! For future videos where cell values are different from the actual digits, it would be helpful for the viewers if you'd stick to a single terminology like "values" vs "digits" rather than describing at length the mechanisms each sentence(like schrodinger addition in this case). Perhaps that's just me though. In any case, thank you again for a lovely time watching these videos.

[@RichSmith77]

Fog tip: If you enter a digit that doesn't clear fog because all the surrounding cells already have their fog cleared, you can remove some of the previously validated digits so that the fog returns, then check if the new digit clears the fog or not. E.g. At 59:00, the 9 in r4c6 didn't clear any fog, so it didn't get validated by the fog mechanic. However, if Simon had temporarily removed the 1 above it, and then entered the 9, it would be validated as it would now remove the fog from r3c7. (Then put the 1 back in 🙂).

[@stevesebzda570]

Lol nice I do that (remove digits to see if the digit I'm going to place is correct). I'm surprised you're mentioned that. That's almost like having the conflict checker on (which I know you're opposed to. I do it though (and use the conflict checker for typos). If it's fine to remove digits (to see if the one you're putting in is correct), that's the same as using the "conflict checker." (I don't use the pencil-mark checker though, it steers you). I'm surprised you're mentioning that clearing digits thing, though, Richard. 😂

[@RichSmith77]

@@stevesebzda570 True. I'm usually against using the conflict checker. I guess I just see this as a byproduct of the fog of war mechanic. There are times when entering a digit clears fog, and therefore validates the digit. If it happens some of the time, I don't really see a problem in making use of it whenever possible. Maybe that is slightly hypocritical of me though. 🙂☕

[@RichSmith77]

I guess I see the conflict checker as being a software addition that isn't strictly necessary for the puzzle, whereas the fog of war fog clearing mechanic is an inherent part of the puzzle. The puzzle couldn't exist without it.

[@stevesebzda570]

@RichSmith77 Yes, it can exist without it. A did a fog one the other day ("a correct digit will not necessarily clear the fog," it went ). It was for the break-in I realized later, but you never knew (yes, all the way through..) That's just that one, though. If in the rules it says "correct digits clear the fog," then yes, it's in there. (NOT "inherently" though ) You're still "checking" to see if it's right, though. Even though I do it (and use it).

The Schrödinger circle (27) threw me. The clue is both correct & incorrect at the same time. Didn't think that was a possibility, so ruled 2 OUT of the circle in box 7.

[@patrickgass787]

It's tricky but the hope is that you will have already experienced a partially correct clue in the form of the lines in the grid - partially correct not being fully correct.

[@maoman4855]

I absolutely loved that so much. Not only is the number scrhrodinger'd, but the _clue_ is schrodinger'd as well! Massive props to Simon for figuring that out, I would have never even considered the possibility had I dared to attempt this puzzle before watching.

[@floyo]

[@ericpraline1302]

Great puzzle, but a total head-wrecker. I think it took me about 2 minutes to forget something. The thing I forgot the most was that zeros existed. Then the circle rule did for me as I completely forgot there could only be three of them in the puzzle (I did not have this problem with any other constraint).

[@blcmd]

Solved in 83:56, which I’m quite happy with considering the difficulty (I’m not a fast solver). I loved the puzzle - especially how the 3 circles resolved. The negative constraint was a nice added touch as well. Well done ViKingPrime!

And poor Simon for not only not having the full rules but being forced to write them down later. Should have jumped in the time machine to read the rules he would later end up writing 😂 This gets me an idea, how would a sudoku variant with time Travel work... oooh

23:30 into my solve I have done decent progress, absolutely loving what is going on so far, but now I'm at a point where I feel like I've used literally every single clue I can see. Gonna have to watch Simon solve to see how to progress one step further.

[@NinjarioPicmin]

Finished at 94:35 wow I loved this. I made two times an error assuming something I shouldn't have but soon realized and back tracked and noticed that I didn't draw any conclusions from that that I shouldn't have. As said before I needed that one hint from Simon in how to proceed, which was Spoiler noticing that one of the German whispers continuing and being real meant that not both V's on it could be real. After that I figured out everything on my own except one more thing, the circle logic. I was convinced I had broken my puzzle but that's a genius solution on how to incorporate circles in the puzzle.

[@stevesebzda570]

About gif or jif @5:44 or so; Saying it verbally (as jif) is confusing. Many reasons. I don't know where to start. "Jif" is already three other things (One since the 40s or 50s in North snd South America -- and probably in the UK now), "Jif Peanut Butter," to name one. Not to mention "In a jif, and "In a jiffy," both mean "quickly or shortly." (That's how "Jif" got its name, btw-- it morphed "quickly" into "it spreads smoothly and quickly.") So, knowing these things ( verbally mistaking "Jif" as "quickly,") someone is going to hear "quickly" when you say "In a jif" or "In a jiffy." (Not to mention again, the word "jiffy," one branch of some Service, calls that rowboat on a ship "a jiffy" -- I don't know which group -- and you won't find it anyway-- but they could joke from that ship: "Take the Jiffy, it's easier and quicker than bringing the whole ship in.") (They'll crash, or run aground, the joke is , lol ) That's where "in a jiffy" came from (that the peanut butter Jif named itself). EDIT: ^^ I'm not entirely sure which came 1st; "in a jiffy or "in that jiffy/rowboat" It's gif (like the funny gift it is) though.. 😂

[@BrinaaSM]

As a German speaker, of course the first time I came across the word I used a hard G, but I later learned that the creator of the GIF said it is pronounced Jif. I didn't change my way of pronouncing it at all though. And now knowing a lot more things that are "Jif" (thank you btw), I will never use it lol So officially it is "Jif" since the creator said so, but according to the dictionary both is fine. However there are soo many more variables playing into this, like public surveys, first impressions, the way Obama chose to pronounce it etc. There are dedicated websites about this even and timelines of the debate, it's kinda funny XD I'm team GIF.

[@jonkess2768]

17:00 If that is true putting a 0 in the middle and two fives either side what do you put on the next cell of the german whisper at least one of the whispers is correct so on of the fives will touch another whisper cell in the row but that cant be a 0 because of sudoku and cant be a 10 or higher because there is already a schrödinger cell in the row.

gif is pronounced by its coiner as jif but as an acronym of its component sounds it is gif and many people analyze the string as gif as it is the ipa(though near high not high) and is the latin reading of those letters(affording english phonotactics on the vowel)

[@vincet68]

Magnificent puzzle - thank you for guiding us through it Simon! (fwiw, I had exactly the same error at the end as I galloped to the finish post)

[@Tepalus]

01:26:46 for me :) Gotta say, the fog really helped to guide me to where to look. What. A. Solve.🎉

[@srwapo]

79:50, this puzzle beat me up. And I had to use the video to see how to deal with the circle clues (there's only three of them on the entire grid, duh!).

[@urmaskaarn4304]

this sudoku is realy wrogn that even Simon got wrogn at the end of puzzle

[@titusadduxas]

1:29:12 - I did make a couple of wrong assumptions on the way and I wasn’t convinced on the circles rule as there were two 2s and one 1 but overall that was very enjoyable.

[@everorizon]

It would have been hilarious to get a circled Schrödinger cell telling the truth. Like... a circled Schrödinger 12, a circled 2 and a lying circle with any other digit. In such a case, both the 1 and the 2 would have told the truth, wouldn't they?

[@patrickgass787]

That's absolutely correct. You could also have three 3s, coupled with two 2s and some other digit than 1. Lots of fun combinations to think about... maybe that'll come up again sometime.

[@finian2]

I wonder if there are any fog of war puzzles that have clues that affect previously placed numbers.

[@fubaryt]

odd fact! "Losing My Religion" was released on Feb 19, 1991. glad to see we got one

[@LiquorStoreJon]

I think this one might test my true love of Fog Puzzles!

[@Gonzalo_Garcia_]

34:48 for me. I don't know how I feel about the way the counting circles are wrogn, I don't really like that combination. Anyway, very interesting puzzle either way!

[@timch5227]

Same for me, in the end if the one with 7 is wrogn, we have only one 2 in circles and if its correct the seven is faulty. I couldnt complete the puzzle on this step because i removed 2 as a possibility from the 9-valued cell

[@AleksandrYgA]

@@timch5227, that felt unusual but in the end the logic is fine - since it's stated that circles don't use the sum as a value it means if a circle has 2 digits in it - it counts like both digits are in the circle and the circle is correct only if both digits appear in the circles a need amount of times. Like with the lines - incorrect line means that at least one of the adjacent pair of cells is incorrect, other pair may be perfectly fine. But I agree that it should've been stated in the rules more clearly

[@HeroDarkStorn]

To defend it, it's not true that lying clue (lying circle) can be ignored, that you can just delete it from the puzzle. After all, the yellow line clearly must be where it is, even though it's lying.

[@Mn0ty]

Not the most difficult, but certainly the craziest sudoku on the channel.

[@guruone]

There once was an accountant named Simon Anthony, Whose decimal dots caused much fiscal calamity. He'd balance with flair, Profits beyond compare, But multiply wrong, leaving wallets quite scanty. Nori, nori

[@tjgansenberg3121]

I did it! And it only took me dozens of not allowed nor required guesses!

[@MaVats]

One of the first deductions was that one of the two double whisper lines must be true. But could it not have been that the line looped around and came back?

[@patrickgass787]

It specifies in the rules that two lines occupying the same cell indicate different lines.

[@steveunderwood3683]

The hardest part of solving puzzles like this is unlearning all the muscle memory responses I have built up from conventional puzzles.

[@diseabronx5075]

And a wonderous number to finish it off.

[@purple4395]

Technically a block and white kropky could also be -1 and -2 as long as that is permitted otherwise

[@estherwestbroek]

I thought it could be 0,1,2 in this instance, but Simon didn't even mention why this could not be...

[@BrinaaSM]

@@estherwestbroek He did. He said there is only one pair of digits where one is double the other (Black) but also consecutive (White), those being 1 and 2. 0, 1, 2 can't work, because 0 times 2 is not 1 and therefore there is no Black Kropki relationship between 0 and 1, only a White Kropki.

[@yuemaeve]

i found one quirky thing. i tried to access the puzzle on my tablet in dark mode. and was just able to see through the fog

[@markp7262]

45:53 finish. Loved the logic on this, and I was lucky enough to not have any missteps on this one. I think that Simon would have benefited a bit from fully coloring Schrodinger vs. not. Excellent puzzle!

[@sebastienlecoq3956]

shrodinger cells, lying clues and fog of war... Like a chocolate cake, with chocolate frosting and chocolate chips.

[@patrickgass787]

Somewhere, it is someone's birthday.

[@JaymanOttawa]

That was a brilliant puzzle and solve! BRAVO!

[@karsaanita]

59:22 for me. This twisted my brain quite a bit 😅

[@CharlesGregory]

At the 38:50 mark; could the correct cage have included a 0 in R6C7 and a 1 in R7C7, therefore not precluding a 1 in R6?

[@NicD]

Wanted to say the same thing.

[@BrinaaSM]

Yes, but this is following Standard Killer Sudoku rules (also explained in the description) which include "digits cannot repeat in a cage". So even if you were to put the cage's 1 in R7C7, it still would be a 1 in the cage and therefore "seeing" the 1 in R6C5.

[@RichSmith77]

38:41 "That would put two 1's in the cage". - Simon He's using repetition in the cage, not repetition in the row.

[@NicD]

Aaah, there we are. Thank you.

[@nicolasraulin1295]

absolute masterpiece

[@phuybrechts6875]

Can solve tricky puzzles , but can set off his phone 😂

[@janeflett4971]

Great puzzle, loved it!

[@zealot2147]

Id love a Schrödinger puzzle but with the constraint “digits appear in Schrödinger cells a maximum of twice”

[@MichaelACromwell]

This was super hard, but super awesome!

[@AndyeKAA]

I already wanted to go to sleep, but i cant miss a wrogn puzzle!😍

[@looweeg4229]

Like clockwork! Love the fog ones!

[@TheKtuno]

Well, too tough for me but I very much enjoyed your solve as always!

[@brianj959]

Fabulous puzzle - loved it!

[@MattiasDooreman]

Idea for setters: train track sudoku

[@leefisher6366]

48:49 - How did you know, Simon, that there were only three circles in the entire grid? I parsed the rules, whilst you were reading them, to mean that there were only three TYPES of circle. For example, let's say 6, 4 and 2. If the 4 is wrogn, then there would exist 8 circles in the grid that contained either 2, 6 or a Schrodinger variation of 6; and any number of additional circles (except four of them) that contained the digit 4 (or 1/3 or 0/4).

[@estherwestbroek]

If you would interpret the rules like that, wouldn't there also be 3 types of black Kropki, eg 3/6, 1/2 and 2/4? If you accept you can fill the Kropki with any digit you need, and there are only three of them, the same has to be true for circles?

[@RichSmith77]

"Each of the standard clue types below occurs exactly three times in the grid". Circles are one of the clue types. So it occurs exactly three times. There's no mention in the rules of types within clue types.

[@leefisher6366]

@@estherwestbroek I didn't think that, no, since a kropki dot (german whisper, X clue, etc) is all you would expect for that clue, where a single application of the circle rule requires X circles for the digit X.

[@estherwestbroek]

@@leefisher6366 ah I see. Valid. Let me tell you the false circle clou that shouldn't be discarded as a circle doesn't sit well with me, it feels wrong. In the comments they state that you should compare it to the top whisper line where you couldn't put a whisper digit or it would be true, but that is different for me, as not fulfilling that line on purpose kind of deletes the whole clue. I also assumed a lie in a circle would then delete the circle, just not the digit. We are both unhappy with the circles!

[@TheSane42]

This threw me too. I had filled in the 1 clearing the fog before realising that I hadn't fully ruled out 0, tried to figure out what I missed and couldn't. The wording is loose enough that I also interpreted it as there being 3 sets of circles, rather than 3 circles total. A set of circles may not be visually connected together like a line, but they're still all part of the same clue. If I _had_ realised there were only 3 circles total I would then have been questioning how I could fit a second good circle anywhere without reusing 1. Not at all intuitive. This clue just doesn't fit well with the ruleset imo.

[@zimmian]

oo the next crossover video with @GMHikaru? Logical.

[@wojciechpietrzak1981]

26:10 it's also true for -1 and -2 🙂

[@six_5000]

96:47 but I definitely got some misclick fog clearage 😢

[@basilefff]

Took me 02:15:40. Good one, and not too difficult

[@SUPER7X]

Simon says “gif” correctly. Legend.

[@xerodeus2337]

happy to watch but won't try this one, I've learned I really don't like lying puzzles lol I love fog and schrodingers though

[@deniseiln]

GIF apparently should be pronounced with a soft G, like jif - at least according to Steve Wilhite, who was involved in the creation of that format. I admit that it doesn't make a lot of sense to me, but then I imagine pronouncing "graphical" as "giraffical", and it... well, it amuses me. For Tegucigalpa... I know someone from there who referred to it casually as "Teguz", so I'd pronounce that third syllable as closer to SEE than CHEE. ...but then... I amuse myself by thinking of giraffical image files.

[@theredstoneengineer6934]

59:32 for me

[@futurefox128]

I absolutely love this one!
