Two 5 Year Olds Set A "Soduko"

[@martysears]

Ahh what a lovely surprise to finish the Easter break with. Honestly, we just made this to hopefully make a few people laugh, and never expected this one to be featured, on account of the long and silly rules. Was so happy that it did though. Myself and Nordy only got chatting about a week ago, and decided we would like to do a collab. Bouncing some ideas around, Nordy mentioned an idea he had for an April Fools puzzle involving a cluttered grid with lots of tautologous pairs of clues which back each other up, with the idea being to find a single liar clue. I loved this concept, and we began discussing it further. Nordy also said it would be quite funny if the rules were also unnecessarily long-winded with lots of spelling mistakes and grammatical errors. This ignited the idea of making it look like a child’s drawing with crayons, and from that point we knew we had to make this happen. We only had 3 days so the deadline was tight! First we made a list of clues that say the same thing that would be funny to include. Most of these made it into the final puzzle, but a few other ideas were 2-cell region sum lines overlapping with palindromes, and a quad clue with 1234 inside a 10 cage. I was then very grateful that Nordy handed me the reigns to play around with the ideas and try and stitch them together into a decent puzzle (despite looking like utter nonsense at first glance.) that was the main idea for the joke. We quickly realised that we could add a bit more fun at the beginning by upping the lie count to 5 at the start, but having 4 of them get accounted for straight away, leaving a situation for the rest of the solve where you only have 1 lie left and so it becomes a game of trying not to break two things at once. This then left the possibility for a fun ending whereby there is only one place left for the final lie. I’m a fan of a fun ending, so it became my mission to engineer a deadly pattern involving one of the clues you deal with right at the start, that only gets disambiguated right at the end by the fact it needs to be broken. The thermo seemed like the ideal candidate for this. This is an example of doing a bit of 'working backwards and forwards', where you have the beginning all in place, and you have the ending in place, and then you have to somehow make it meet in the middle It is actually quite tricky to force a deadly pattern like this without other clues resolving it prematurely, but I particularly enjoyed this challenge. For the artwork I took advantage of the fact you can have a background image in sudokupad, so I made the entire thing as a background image. Found a nice paper texture and some crayons from the internet, and a childish handwriting font. The most fun was obviously drawing Mark and Simmon and the scrabble bags. There is something strangely liberating about drawing in the messy style of a young child! Thanks to Nordy for being an awesome collaborator and providing the initial ‘tautologous clue’ concept, and to Juggler for testing. And mostly thankyou again Simon for the unexpected feature and the brilliant and wholesome daily entertainment 😊

[@thejuggler42]

It's certainly the best Soduko I've seen.

[@stephenbeck7222]

I would absolutely not count two or more lies in box 5 as a lie for Mark. The presence of two lies does not make ‘there is a lie’ a false statement.

[@soulus98]

Agreed. “There is only one lie” or “There is a single lie” would do what he thought. Though I’m sure he was considering that

[@HalfBakedLunatic]

That is one of the funniest things I have seen in a long time. Well done. Of course ... it begs the question of: What if "Normal Sudoku Rules Apply" is one of the lies? (As the universe collapses in on itself 🤣)

[@andersosterholm2538]

Or if "all clues are telling the truth except 5 of them" was a lie 😁

[@BramMertens]

Luckily despite April folls and wrogn, lying clues there are some things we can always rely on like Simmon finding a brilliant roundabout way to deduce a digit that's been available through sudoku for several minutes. Another wonderful puzzle and wonderful solve.

[@pjbrady47]

The "Escher Staircase" sounds like a great new sudoku clue. Four cells in a circular arrangement with the understanding that they're either ascending or descending with one exception for the solver to determine.

I was trying to make my own sudoku puzzle yesterday and having troubles trying to create just one. Major props to these five year olds who did this. It's not easy.

[@evanbasnaw]

I really like how the last lie resolved the puzzle. This was a beautiful take on the Wrogn style. Hats off to Mary and Nordy. I can't believe they created such an intriguing puzzle at age five. That's incredible. Simply in-credible.

[@emilywilliams3237]

This was entirely entertaining and also an amazing sudoku. Thanks to Marty and Nordy and their childishness in writing the rules and drawing the grid. Absolutely funny and impressive. Thanks, Simon! The clues outside the grid were especially funny and especially ... . . . . ... your laughing at Mark telling the truth given what he did in his video tonight.

[@anders3742]

The funny thing is, if you assume that the "age 5" is a lie, then you only need four lies in the puzzle and the last part of the puzzle's answer would be reversed - And that'd be the only difference.

[@RichSmith77]

"We have even put some *red* clues outside the grid". I think because "age 5" isn't red, it means it isn't a clue, so it cannot be a lying clue.

[@benwhite5734]

@@RichSmith77Also I think it's out of bounds to even consider it because it's not related to any logic in the puzzle and because we're not ever supposed to take it seriously (I'd like to meet the 5-year-old that could set _any_ 9×9 sudoku, to say nothing of one this complex).

[@Barteks2x]

35:30 I may be wrong here but I think this is not quite correct to assume this one must be correct, because one of them could be one of the already counted ones. So if both were wrong, and all the other clues in box 5 were correct, it would still be fine. Edit: It turns out to be correct at 56:33 anyway, but I think at the time, this deduction wasn't correct

[@borisgrozev2289]

I came to mention the same. Brilliant puzzle!

[@RichSmith77]

I agree. If the X / grey line were lying clues, but the only lying clues in box 5, then it would still have only been taking the count of known lies to 5, since one of them was already being counted in the four count. (Although I think you're missing a "not" somewhere - "this is not quite correct" or "this is not now correct" maybe?)

[@Barteks2x]

You're absolutely right. Simon was just lucky there. That deduction could easily have been wrong.

[@Oscarefraim]

This soduko was so out of the box it was amazing!

[@somethingsomething259]

This is exactly the type of puzzle I love to see and dig into on here. Easy to figure out what's going on, but takes a solid amount of work to deduce what needs deducing, with little bits of progress steadily dripping along. And of course I got bamboozled on my prediction for the final wrogn clue! Clever, clever throughout.

[@cryam6428]

The amount of details and references in the puzzle are a true treat.

[@RoderickEtheria]

Something's wrong with my puzzle link. The rules are there, but the puzzle looks nothing like presented. Ah, must have had the image off.

[@cnoize314]

Maybe I missed this being considered but Re: the 10 line and 16 cage, there is a possibility to make the line work and the cage break if you make the 4 cells that are both on the line and in the cage add to 10 (satisfying the line) but with a repeated digit (breaking the cage even though the sum is still 16). However, you can only repeat one digit (r6c6 in r7/8c7), and with 1 & 2 already placed in box 9 the only options are 3,3,3,1; 3,3,2,2; or 4,4,1,1--- all of which break sudoku with more than one repeated digit

[@kpwxx]

One other tiny thing - Simon incorrectly, I think, assumes early that the X in box 5 is correct (marking it green), forgetting that one mistake in that area is already accounted for so it would only necessarily add one to the total lies. However, all other deductions made after that can be made without it, up until the point where he correctly deduces that the bottom grey line in box 5 is a lie, which then confirms that the X is not a lie as that would leave us with 6 total lies. An absolutely magnificent solve and a wonderful puzzle!!!

[@benwhite5734]

I think that "contains a lying clue" means it contains _at least one_ lying clue and we weren't meant to ponder whether it's singular or plural. Every set that contains multiple X's contains an X.

[@HunterJE]

Yeah without any explicit qualifiers like "exactly" a box that contains three apples does contain "an apple" (in addition to two more apples)

[@ianoz1]

That had me... when the 2/7 in box 3 wasn't forced to be incorrect by the set-up to the final "lie". I had no clue until I watched the whole solve. Brilliant jape!

43:18, holy heck, I actually solved this! I stared for like 20 minutes, put away my tablet to watch the video, stopped myself, and then got going a minute or two later. The multiple clues on top of each other (eg, two cell gray line with an X) made some of the clues basically worth 2 points, which made having more then 5 incorrect quite simple, "proving" lots of things to be correct.

[@Mephistahpheles]

It always amuses me how different people can think so different. Simon regularly stuns me with his insights, but then the 16 cage seemed trivial to me but gave him pause.

[@JaymanOttawa]

What a FABULOUS puzzle!

[@lukasmbrito]

At 35:25 when Simon says that the X and grey line clues at box 5 are true, he is using the logic that if both clues are wrong, then the puzzle would have 6 lying clues, since he already identified 4 of these in the puzzle. However, one of these lying clues is inside the killer cage of box 5. I wonder if that works, since it could happen that there are two wrong clues in box 5, they are exactly the X and grely line, and that would give only 5 wrong clues. What am I missing? Edit: Several people have already pointed that out. Apparently Simon is just too good XD

[@abydosianchulac2]

That would break a literal interpretation of Mark's clue that there is "a" lie in that box, since he doesn't say "at least one lie" or that "lies are". Some other commenters' attempts to say his clue wouldn't be lying if there were multiple lies in that box are using an unusually loose approach to reading the rules for sudoku.

[@tommo4356]

@@abydosianchulac2 I wouldn't say its unusually loose when part of the joke is that the sudoku is seemingly made by two 5 years olds who don't know proper spelling or grammar. It makes sense to view Mark's clue as saying 1 lie, but I think most people would be ok with it as 1 or more.

[@johncox7169]

I think it is more that Simmon knew for certain that there was 1 lie in box 5. He always accepted the fact that there could be a second lie there (and he checked at the end of the puzzle for that second lie) but he couldn't know for certain that the second lie was or wasn't there until closer to the end (although he could have figured it out much sooner that he did, since The Secret would have told us that the killer cage was correct as soon as he had the 7-3-1 clues outside the cage.)

[@Twiztedgoalie]

I now have the urge to make a chocolate teapot sudoku. The idea: the teapot melts, and numbers from higher up on the teapot, get added to lower levels as it melts. So if you had, say a string of : 9 on top 3 and 5 middle 2, 4, 1 bottom The actual values as it melts are: 7 on top 1 and 4 in the middle 3, 6, 2 bottom The 9 had 2 on the string beneath it, so it lost 2 (1 to each of its children). The 3 became 1 as it melted away 1 each to its two children beneath it, etc etc. the 4 became six because it got 1 added from both the middle row. You could do some weird things with having single strands melting, double/triple strands, etc. And the real tricky part is that the number put in might look like it breaks sudoku. But because of the melting, the actual number will not break it.

[@Rubrickety]

This was so much fun to solve. I'm proud that I predicted a lot of the deductions based on the "What would be coolest and/or funniest?" principle, including the awesome finish. (Proving my predictions logically wasn't so easy though!)

[@paulanderson5704]

Simon at 38:45 putting a 9 and saying "this is probably important". Himself half a minute later: "How can possibly resolve a bottom line?" And at 58:29 Simon was so happy, that r5c4 is no 2, not because it's literally upper diagonally at the same box, but because there's no 1 and 3 near. Also Simmon at the grid was telling the truth!

[@HalfHeartGames]

Its wonderful to see an idea you had actualized so well. Way back when you were taking submissions for the "Detective" theme month, I was putting together a sudoku where you had clues where only one was lying. You had to figure out which clues gave mutual alibies (i.e. if one is wrong the other is) and then deduce the lie. It worked out a lot like this puzzle when simon found the first 4 lies. This takes it to the next level though. I knew it had potential and Im glad someone was able to create it.

[@martysears]

ahh thats cool! we actually started out with there only being one lie, but then we thought it might make a more interesting beginning if you had to find 4 lies that were fairly easy to find, before the rest of the puzzle can begin properly

[@PeterLostig-kx2hg]

you probably made a wrong assumption then, 4 lies are easy to find at the start, but the thermo lie is only findable at the end. this way you have to find out the clues that back each other up, so they have to be right (otherwise you would have 6 lies). the thermo could easily be right, it just has to be broken to get ot the total of 5 lies

[@bobblebardsley]

As a fan of the movie Labyrinth, Bobbins the Cat's statement feels like an old friend. (This is not a bad thing.)

[@LithmusEarth]

I don't know if I've so thoroughly enjoyed sitting through the rules. I just sat there at 1x Speed. Your delight! Also yes, the additional art adds to this.

[@LithmusEarth]

So 3 Lies off the Bat: (16:00) Simmon's Words are a Lie OR Bobbin's Words are a Lie. The four Inequality signs in Box 7, One of those has to be a lie, they cannot all be true. Technically more could be a lie, but at least one. Mark's Words are a Lie OR One of the clues in Box 5 is a Lie. I'm just trying to like big-picture figure it out, because then you can sort of figure out what can't be a lie, or figure out more of what's true, I also wonder if you could start assuming some stuff as true and figure out when you bump into a lie. Might have to backtrack a lot of the puzzle. Also there are 2 green lines in row 9, which means if one turns out to be a lie the other is too, and you've found all 5 lies including the other three I've mentioned. Which things like that, are all over the board. the double enforced 10 clue, 10 cage, 10 x, grey line stuff, where if you make one thing a lie, you have to make a lot of things liars, and generally might mean you make TOO many things lies. Like the thermometer in the top right, or the arrow in the lower left, etc. etc. tons of reinforced clues that would be hard to have multiple lies, but it's possible.

[@LithmusEarth]

31:38 Yep I definitely caught onto that, you gotta keep your lies to a minimum. Brilliant work as always so far. You are spotting more sudoku things that I could at first glance.

35:25 he fell for the trap. All of the other X's on grey lines have to be true because you only have room for 1 lie, but the grey line X in box 5 could still be wrong because you already know 1 of the clues in that box is a lie so you'd only be adding 1 more lie if they are both lying

[@samueldeandrade8535]

Exactly!

[@stevieinselby]

Well that's a good laugh ... although I don't quite know what's going on. I solved the puzzle finding 4 lying clues, so I assumed that the fifth clue was the clue that 5 clues were lying, but the puzzle says it isn't quite right, so I guess I'll just have to watch the video to find out! Simon and I definitely have different frames of reference for the ring of >s ... he goes to Escher, I think of Meat Loaf ("Everything louder than everything else") 🤣

[@lhesitante]

I spent a good few moments polishing my computer screen earlier today. At least, I now have a clean(-ish) screen.

[@PassionPopsicle]

Decided to save the video for this morning, because I was too tired last night, and I'm glad I've got my full wits about me, reading the rules! 😂 This is extremely funny, and worth it, whether the puzzle is good or not (though I am sure it will be brilliant)

[@Akatsuki69387]

This is the first, and possibly only, wrogn puzzle that Simon hasn't immediately lamented about upon opening it.

[@galoomba5559]

57:19-58:35 the most elaborate way to get that 2 at the top when you could've just resolved the pair from the beginning

[@5t757]

Managed this in 37:19. What a lovely innovative idea by these two!

[@doublepudge465]

Sven’s next project: a toggle in options for standard graphics or cartoon graphics !

[@zirco77]

This one was only a single "background image" with all the clues, but indeed a cartoon style would be a great addition!

[@evanbasnaw]

I would definitely need the toggle. I've been trying to work though the Fog of War kickstarter puzzles. Beautiful background images, but I totally missed some early clues because of the style. (The rest of my issues were entirely on my own tenuous grasp of anything resembling logic though)

[@Alex_Meadows]

Never mind the puzzle, the rules themselves (as written below the puzzle, not on the screen) are a work of art 😆

[@KrisCadwell]

That was a great puzzle, well done constructors.

[@10prozenthimmel]

I love the puzzle and all the creativity that went into it. I also admire Simon’s reasoning at the beginning. I was kinda able to think one or two steps ahead of what he said (when he was definitely already there, just words are slower than brains). However, @ 39:07 I had to laugh out loudly. The way Simon regrets not being able to resolve the green line after just putting a 9 in the grid… 😂 probably his idea of an April fools joke 🤣

[@HunterJE]

26:47 It's one lie worse - putting a non-5 in the bottom left corner requires at least one of the arrow and the 5 killer cage to be a lie as well

[@Bur6212]

Did anyone notice the little blue and orange squares “simmon” is holding to represent his shading of high and low cells?

[@martysears]

Hehe they are actually his scrabble bags that he often likes to use to help explain SET

[@mackthisarrowhearth295]

This is honestly my favorite sudoku this far. Its both in logical and astatic amazing.

[@sjm6280]

A digit other than 5 in r9c1 would cause not three but four lying clues, since either the arrow or the cage in box 7 would also be lying

[@Daymickey]

Can there please be more puzzles like this with graphics and well developed themes? This was so fun! They did a great job! How can I make a request of the setters?

[@martysears]

What do you want to request? 😀

[@Daymickey]

@@martysears ahh! What about a map of a suburban neighborhood? It can have a school, post office, bank, houses, a park, perhaps each part can be a unique sudoku region. Another thought is something nature related. Like let’s say a day at the beach with sand, water, sun, beach ball, even sunbathers. The suns rays can be renban lines or arrows. There can be an outer space themed one for the upcoming ECLIPSE! With planets, moons, shooting stars, rockets.

[@PauxloE]

I got stuck several times, so this solving was spread over three evenings. Finally I now finished it up with a bit of Sudoku. Total (non-paused) time 207:18, solve counter 3720.

[@total_dk6517]

Wasn't that familiar with Nabna lines, so I spent a lot of time being stuck theorizing about combinations of 2 lies. The secret at 28:25 helped me get going.

[@Vedvart1]

I believe a mistake was made at 35:27 - The grey line/X clue does not need to be true at this point, because while it *would* contribute two lies to the puzzle, one of them has already been counted as the box-5 lie to make the 34 cage and its contained clues not break the puzzle! So the other lie added would simply be the fifth and final lie.

[@chris5619]

I think Simon made a mistake ruling out the ten line X in box 5 (34 cage) at 34:57. He was ruling out clues that would create two lies since we were already up to 4 lies. But, the 10 line X could be wrong, with the other clues in the cage, and the cage itself being right (at that point). For instance, a 78 on the renban white kropki, a correct 10 on the bottom 10 line, and the digits on the 10 line X being 36, which would make the 10 line and the X clue wrong, but that could just be "one additional" lie in addition to the minimum 1 lie we knew about in that cage.

[@Afterthoughtbtw]

I love wrogn puzzles - although I prefer it when everything is wrogn - and this one had me laughing out loud a couple of times in appreciation. Lovely puzzle.

[@bobsburgers8885]

What a brilliant puzzle. And for the first time ever, I solved a puzzle where the video was an hour+ long without it taking me days 😂

[@aliengeo]

Simon looking at a Sudoku box that already has a 2 in it: this cell can't be a 2 because then this other one would have to be a 1 or a 3

[@frankjiang1857]

Finished in 31:23. Lovely logic in the breaking of rules and what could and couldn't be non-lying rules. Fun puzzle!

[@studgerbil9081]

agree with several posters below that the puzzle has two solutions: the one Simon found with the 2-7 in box 3 disambiguating, or that Marty and Nordy are not in fact age 5 and the puzzle has two possible solutions.

[@trainsinpoland]

The instructions clearly state that the relevant clues outside the grid are RED, "aged 5" is written in lilac.

[@martysears]

@@trainsinpoland hehe yeah, I thought some people might think that the age 5 was the lie, that was the reason for making the outside clues red

[@abydosianchulac2]

​@@martysears That was good of you, but it should have been obvious to players from the get go; you had already established the lies were all clues, and "age 5" isn't a clue for anything.

[@studgerbil9081]

@@trainsinpolandthe lilac is a lie. Also, the chocolate cake is a lie.

[@CineMiamParis]

« Age 5 » is not a clue. So whether it’s a lie is irrelevant.

[@SkillZgetKillZ]

60:04 to get it waiting for so long for that final liar to be revealed after finding most of the rest so early was holding me back

[@AppelmoesArtandPhotography]

This puzzle is amazing! I was thinking the entire time that there might be 4 false clues in the grid and that the fifth lie was actually the age of the setters, or that there are 4 instead of 5 because of April fool. It kept me in the edge of my seat till the end. Also the eyelash was very funny.
