** TODAY'S PUZZLE **
An innovative and exceptional sudoku today from Crusader175 who, with the help of Chameleon's amazing software programming, introduces us to a completely revolutionary type of puzzle (see what we did there!).
It's called Wheels On The Bus and this one will have you shaking your heads in admiration.
Play the puzzle at the link below:
yusitnikov.git...
Rules:
Normal sudoku rules apply. Cells in the same relative position in different 3x3 boxes cannot contain the same digits. (So, for example, the top left cells in each 3x3 box must all be different.) Digits on a circle have to be placed in the same circular order in the four cells that are touched by the circle. The circle has to be rotated 90° clockwise N times from the current position. N is the digit in the cell inside the circle. Eg, if R2C8=6, then R1C8=8 and R2C9=4.

Thank you very much Simon for featuring another puzzle of mine and for very kind comment! I’ve been exploring Wheels Sudoku lately, it feels like a very underrated constraint. Would love to see more puzzles with it. Normal Wheels Sudoku didn’t have the number of rotation rules, but I think it works very well for this puzzle. Shoutout to Chameleon for the software and to Malrog for Pivots mechanic inspiration. Hope you all enjoy the puzzle as well!

1) Simon has the brilliant insight that each coloured centre cell has to come from one of the mod-4 sets {159},{26},{37},{48} (excluding the set that's common to those particular coloured wheels). 2) Simon forgets the above for most of the solve! You have the purple {159} set in box 3, so you can remove 159 as candidates from the box 4 centre! Also, disjoint sets allows you to remove 9 from r1c2 for ages, starting a whole string of deductions.

Yes; if he'd thought in terms of equivalence classes mod 4 he could have made his life much easier, I think. You don't care at first whether such-and-so central digit is a 2 or a 6, just that it is one or the other of those. Very nice puzzle, though, and I greatly enjoyed watching the solve.

@Alteram 11 ай бұрын

Yeah I ended up painting in the [159][26][37][48] triples into the boxes and removing colors they couldn't be and it helped a lot in the beginning, and then near the end I completely forgot about disjoint sets on a 279/79/79 triple for the 2.. So I can't blame Simon for forgetting about earlier logic lol!

I love these videos where Simon gets confronted with a new logic. We get to enjoy his genius at work. I'm quite sure that if I had tried this myself, I would have been lost a long time in figuring out where specific digits could or couldn't go. Simon, in contrast, sets out to *truly* understand the logic. And sure enough, he does. And explains it nicely, too, with the three colours and the four rotationally equivalent sets, and the fact that once you determine one set for a given wheel, the sets on the other two wheels of the same colour can be derived. The funny thing is though, it's also typical Simon to immediately forget to apply this logic. Let's call him a "distracted genius"!

@zirco77 11 ай бұрын

In other news, I just noticed: if you type two alternating digits in a wheel center (e.g. 1,2,1,2,1,2...) "just fast enough", i.e just before animation completes, the wheel spins faster and faster... then in settings, set animation speed to slow, and they'll spin for a while once you stop typing. Then you can try to make 4 or 5 wheels spin at once! Yeah ok, I solved the puzzle and I was just messing around, it's about midnight here. But rest assured, I can still be invited to parties. 🤣

I was just gonna sit tight and watch the video... Then I thought to myself to try it out beforehand. Got stuck looking at a blank puzzle for ten minutes. Decided to watch video. Started to watch it, but before actually seeing anything happen I thought to myself to try harder. Then a lot of insights came, one by one, building up little by little from intuition and eventually I understood the mod 4 beauty behind the puzzle. From there I wouldn't say "smooth sailing" but I managed to break in and then I was off to the races. One hour later, with only my wits... I was done! I'm so proud of not having given up in the end!

What a fantastic puzzle. I had a much faster break in by pencil marking 1, 2, 3, and 4 in all the center squares based on the number of turns they could have (ignoring 5-9 initially). I was able to make a lot of eliminations pretty quickly that way and start pencil marking all the digits on the wheels.

I did the same. It looked intimidating based on the title and thumbnail, but it turned out to be very approachable for me. Plus I appreciated that the puzzle let me know when I got the rotations right.

@NettoTakashi 11 ай бұрын

A very lovely solve. Something fascinating that didn't come up in Simon's solve (because he keeps "Auto-Check On Completion" turned off) is that there's actually two stages of completion check-- one for the wheels, then another for the puzzle as a whole. When I filled in the last digit in the center of a wheel, I got a pop-up confirming that the wheels were all correct. Which I found pretty interesting.

it's great that it's there honestly. i have a history of making mistakes in these puzzles and getting all the way to the end before being told "you are dumb" is one of the reasons i don't do these puzzles often. (i did do this one tho, it was too interesting to pass. :P)

@MrAranica 10 ай бұрын

This just happened to me too. I made 4 sets of numbers: [159,26,37,48], then the 3 sets of wheels [Red, Green, Blue] - from those 2 sets, I made out 8 different solutions to the wheels, and with knowing R5C2 was forcing 4&8, and R5C8 forced 2&6 into a vertical lock, it was easy to find the solution for the wheels. I was in shock when the popup notified me.

@zirco77 11 ай бұрын

Brilliant! Thank you @CrusaderPuzzle for that puzzle, I really liked this totally new, out-this-world constraint. Funny though how Simon is normally quick to mention modularity in some others puzzles but didn't spot (at least not explicitly) that all wheel centers were arranged in a modulo 4 sub-puzzle. I was really expecting Simon to go on with explaining modularity as he always do so well. He was nearly there with his yellow digits set, but ended up resolving centers by combining parity constraints instead. Anyway, in the end, that still made the wheels on the bus go round and round.

@ApesAmongUs 11 ай бұрын

Simon lost the conclusion pretty quickly that you could only have one number from each set in a color. So, once he got 159 in the center in box 3, he could have eliminated 159 in the center of box 4, leaving a 37, which would have allowed him to place the 458 immediately.

I really enjoyed this video - I am coming to it a couple days after it was initially posted because of busy times here, and I'm so glad I watched it! I disagree with some comments below about your forgetting deductions and logic that you discovered, or failing to use it, or whatever. I felt, from my vantage point of being a watcher and not a solver of this puzzle, that you did keep things in mind very well. I don't really understand the comments that suggest that you didn't. Nevertheless, as always, Simon, your glee at the new constraints and software to support it is almost as much fun as the solve! Thanks for this video and for everything that you (and Mark) do to keep the sudoku puzzles coming two-a-day every day of the year. It is such a source of pleasure to me to know that I will get to see you wrestle with something beautiful every day.

@mrrobotman5299 11 ай бұрын

Very early I was able to figure out that the fact there were 3 circles from 3 modular 4 groups. 2/6 are 2 mod 4, 3/7 are 3 mod 4, and 4/8 are 0 mod 4. This combined with the inital configurations meant that for each of those there had to be a rotation from each of the other 3 groups. Made figuring out the circles fairly straightforward.

@markp7262 11 ай бұрын

26:00 finish. I took each pair on the wheels and mapped out possibilities, noting that some combinations of positions will break the disjoint sets. This proved that the wheel in box 1 had to be even, and in box 6 had to be odd. This break-in allowed me to finish the wheels quickly, leaving a tricky disjoint sets puzzle remaining. Excellent!

@_aullik 11 ай бұрын

I also played around with the wheels in the beginning, noticed that when you just choose one of the 3 rotation possibilities for each wheel it solves the other 2 wheels. It also makes the parity thing quite obvious. So you end up with the 48 pair and the 26 pair and from there on you get the 9 wheel digits relatively quickly.

@UndeadFil 11 ай бұрын

It came very quickly to me that there was a strong relationship of modularity for wheels in boxes 1-5-9, 2-6-7 and 3-4-8, and once I found what this implies for the modularity of wheel 6 and the consequences in boxes 3 and 9, the rest of the solve went pretty smoothly. Very fun and unique puzzle!

That was a really fun sudoku! I struggled to find somewhere to start so after a while I just started trying different configurations of 2-6 wheels to see what combinations I could rule out. That went badly until I realised I had forgotten to rule out the nave of the wheel being 2 or 6. At that point it all started to flow a bit more. It still took me an hour at least.

@Robert_H. 11 ай бұрын

For me, Sudoku broke down relatively quickly. (1) Similar to Simon, I first determined the three wheel-groups: 37-group in Box 1/5/9, 26-group in Box 2/6/7 and 48-group in Box 3/4/8. The respective groups must have different settings (Modulo with 4) to satisfy the Disjoint Groups rule. (2) Then I looked at each of the three groups individually and found only the following settings for them (taking advantage of Disjoint Groups rule): Box 1 (Modulo 0,2), Box 2 (Modulo 0,1), Box 3 (Modulo 1,2), Box 4 (Modulo 1,3), Box 5 (Modulo 1,2), Box 6 (Modulo 1,3), Box 7 (Modulo 0,3), Box 8 (Modulo 2,3), Box 9 (Modulo 0,1). (3) Because Box 1 always has a horizontal setting and Box 6 a vertical setting, wheel in Box 3 sees a 2367 quadruple. Thus it loses its modulo 2 setting and is clearly modulo 1. (4) The causal chain now reads: - by quadruplel: Box 3 is modulo 1 with 4 in r1c8, 8 in r2c7. - by disjoint groups: Box 4 is modulo 3 with 4 in r6c2, 5 in r5c1, 8 in r4c2 - by disjoint groups: Box 8 is modulo 2 with 4 in r8c6, 8 in r9c5 - by 48-pair in Box 4: Box 1 is modulo 2 with 3 in r2c3, 7 in r2c1 - by disjoint groups: Box 5 is modulo 1 with 3 in r4c5, 7 in r5c6 - by disjoint groups: Box 9 is modulo 0 with 3 in r8c7, 7 in r9c8, 9 in r7c8 - by 48-pair in Box 4: Box 7 is modulo 3 with 2 in r9c2, 6 in r8c3 - by disjoint groups: Box 6 is modulo 1 with 2 in r4c8, 6 in r6c8 - by disjoint groups: Box 2 is modulo 0 with 1 in r3c5, 2 in r2c4, 6 in r1c5. (5) All wheels have been determined and the corresponding numbers written in the adjacent cells. The rest is simple Sudoku.

Well done Crusader175 for the wonderful puzzle! We actually agreed to do a puzzle test exchange last week as he needed this rated on LMD and this was the puzzle I got to test. I'll definitely be sending in the puzzle I gave to him to test, think you might like it, Crusader175 thought it was fun. (Hint: It's a sequel of sorts to my last feature on CTC). Back on when I tested this one, I was stumped for an hour. I knew it had something to do with mod 4, and all the wheels that had say, 3 and 7, had to have one of 159, one of 26 and one of 48 in the centre, but I couldn't get the logic right. I broke the puzzle twice. Eventually I just deduced r5c8 had to be odd and got a 26 pair in box 6 and went from there. It is an extraordinary ruleset and the constraints work really well together. I'm jealous of the people that experienced the lightbulb moment upon finding the break-in. Well done again Crusader175.

Very early, we knew that the top right purple cell was a 159. But those are all the same mod 4, so we know the left purple cell can't be any of 159, so you can reduce it to 37 much earlier. It was figured out pretty early but then forgotten that, for the wheel cells, you get to think of 159, 26, 37, and 48 as equivalence classes (so pencil marking an orange cell as only 37 means no other orange cell can be 3 or 7, for instance).

@JustSomePasserby 11 ай бұрын

Yeah, when he deleted the four yellow cells marking the mod-four sets at 36:30, he immediately abandoned all logic involving them. The very next thing he did was spend a minute and a half on a deduction that only would've required checking them.

Simon the way to attack this puzzle after the break in (which I never could fully understand) is to focus on the disjoint subset on C2/5/8 and R2/5/8. You missed some disjoint opportunities here.

After 13 minutes of watching Simon and untold how many minutes of pondering on the problem, I'm questioning if it's possible to have a unique solution... I'm sure it must, but it seems like the wheels don't interact enough, there's no one wheel with a 3 and a 4 on it. So it seems like all the 3-7 wheels could be placed at "correct" orientations relative to each other, but they don't put any pressure on the 2-6 wheels, couple this with modulo automatic that tells me that each orientation can be fulfilled by at least 2 different digits... And it just seems like there's too many options and not enough pressure... So now I'm going to sit back and finish watching Simon to see if it actually works 😂

What was interesting for me is that because of the arrangement of the numbers there’s a sort of disjoint sets within the coloured cells with respect to the different combinations of rotations. 4 sets of rotations, one is ruled out by the numbers on the wheels and if you put something from one rotation set in a coloured cell the other two cells of that colour must be from the other two sets of rotations because the numbers on the wheels are a different number of rotations apart.

From the 33 minute mark to the 42 minute mark (so 9 minutes total); Simon could have had the 4/8 disjoint in Box 6 solved.... And he ended up solving it with the 5 disjoint from Box 9. Amazing how he can do such supreme feats of logic and still miss super simple deductions so easily.

What's funny is that it's a deduction that he had already made, that each of those boxes needed to have one of each "set" of the digits.

Wonderful puzzle. This may be the first puzzle that I significantly beat Simon's time on. Something just clicked about it for me, probably because I had been thinking of constructing a similar puzzle ever since Chameleon offered his services for puzzle mechanics in the comments for Rush Hour.

That was an interesting puzzle, I love disjoint set ones and coming up with a way to decide how the wheels was arranged was pretty interesting. Once I noticed that there were three "sets" of wheels I played with how they interacted and found sets of digits that worked and kept them separated since any mod4 of that digit would be the same rotation. Once I did that to another set it started eliminating possibilities and I knew I was on the right track.

@MatthewBouyack 11 ай бұрын

This puzzle is absolutely brilliant!! It was certainly no easy task, but the moment that I finally understood how the parity of the different wheels interact was well worth the effort! Final time was 1 hour, 49 minutes, 9 seconds

Great puzzle because right from the start it gives you a lot of info in the way of "if this is A then this must be either B or C and then this over there is (D or E) or (F or G), depending on the second. - And among this clutter of information you have to find the essential first step to enter the first 3-7; 2-6 and 4-8 pair pencil marks.

About an hour for me. As is so often the case, I managed the break in perfectly quickly and then completely failed at properly doing regular sudoku (and disjoint set).

So I haven’t watched the video in its entirety yet (11.51 minutes in) but I just thought of something before Simon did in the video (idk if he figures it out I’m about to see) The very center square cannot he 3 or 7 cause no matter orientation, normal sudoku rules will apply. I assume he gets that figured out, but I’m happy cause he normally has me stumped and I thought of this before he did in video. Love yalls work btw!

Coulda made things easier on yourself by taking 159 out of r5c2 when they appeared in r2c8. Since those two have to be different mod 4 due to being the same color.

Nice one. Once you see the break in you can solve this one quite linearly.

@darkreflectionsstudio4506 11 ай бұрын

I was lucky, when trying to get a feel for the first rule. I noticed that the 3’s, 2’s and 4’s are all in the fifth cell of their boxes and that there are exactly 3 such boxes each. That made it easier to spot, that each of the wheels has to be rotated a different number of times. That each 3, 2 and 4 on the wheels was paired with the number 4 higher, meant that the N on the wheels could only be chosen from 3 sets of digits for each group.

@stangerrits6712 11 ай бұрын

Something to select all the 'cells in the same relative position in different 3x3 boxes' would have helped a lot here. Would be similar to what you can do with thermometers now, click and hold a cell in a thermo, and automatically cells on a similar position on another thermo with the same length will be selected.

Wow, I usually don't attempt these longer ones, but the ruleset was so interesting that I had to try. The break in was really tough and it took me a long time to get going, but it was very satisfying when I got that little pop-up telling me that I solved the wheels correctly. What a fun puzzle!

@KatieM2262 11 ай бұрын

I loved this one! It was challenging but fun. I found a “shortcut” to narrowing down the possibilities for each circle. Possible spoiler: Once I discovered the tricks about number pairs/groups that couldn’t go together and circle parity, I went through and eliminated the possibilities from each circle. If I saw a circle had to contain only digits from one “naughty” number pair/group I could eliminate those possibilities from the partner circles along with the digits from its group (I.e. the center circle had to have 1,5, or 9 so I took those out of the other 3/7 circles as well as the 3 & 7). This along with the pairs helped eliminated digits until I was able to get all center digits and continue from there. Idk if this makes sense because I’m horrible at explaining how my brain works when I see a solve path but it helped a lot

Wow that was challenging. Pushed my half drunk IQ to the limit. Thankfully the triplets of: 26, 37 and 48 existing and being on different rows/columns made it somewhat manageable to color/name the wheels. If someone's stuck here are my notes that I'm sure will greatly help you: YELLOW: 2: not+1 = 2/3 3+1=not possible 3: nto+3 = 1/2 3/2 or 2/1 RED: not 5, 2: not +3 = 1/2 2+3=not possible 3: not +2 =1/3 2/1 or 1/3 BLUE: 2: not +1 = 2/3 3: not +2 = 1 159 BLUE start1(2/1cont) 26 YELLOW start1(3/2cont) BLUE start2(3/1cont) 37 RED start1(2/1cont) 48 RED start2(1/3cont) YELLOW start2(2/1cont)

@ 11:07 - "I can't do sudoku" - Finally an admission - I've been telling you that for months. It's not normal sudoku, but you can certainly use the disjoint set rule. You've currently got three wheels with a 3 at 9 o'clock. Each of these needs to be rotated by a different effective amount (i.e. one must be 2 or 6, one 4 or 8, and one 1, 5, or 9). There's only limited relative arrangements of these which avoids a digit in the same position. Having found a relative arrangement with no clashes, you rotate all three by the same amount to maintain their relative rotations to ensure none of the three had a 3 or 7 in the centre. You've also got three wheels with 48 on them, with essentially the same restriction, and also three containing 26. Each of the groups contains one wheel where the 26/37/48 digits are on opposite sides, which means they exclude that rotation from any cells in the same row/column depending on the orientation. E.g. the wheel in box 6 cannot be rotated 2 or 6 times. If it's rotated an even number of times, it means none of the wheels in R5 can be rotated 2 or 6 times. If it's rotated an odd number of times, none of the wheels in C8 can be rotated 2 or 6 times. Summary: the set of wheels with 37 needs a 159, a 26, and a 48, the 48 set needs a 159, a 26, and a 37, and the 26 set needs a 159, a 37, and a 48. Towards the end of placing the wheel hubs you missed out on the one of each type per colour restriction, so for instance you had 15 in one purple, and 13 in another. The latter had to be 3 because the first was the 159 entry, and so the second couldn't be 1. By having the auto-check on finish turned off, you missed out on the celebration when you filled in all the wheel rotations. Although I really enjoyed it, I'm not sure this innovation has the legs for producing others of the same type. It would be a shame for quite a nice bit of code to only get one outing though.

@JalebJay 11 ай бұрын

While opposite side for 8s is true in your post analysis, it's more important that 8 in relation to 4 is always at a different angle in all 3 dots. This would not only require you to use a different set for each center, but you can immediately find the order given by these clues. If you use mod 4, and assume the pair you're using is {n}, then the order will always be when the pair are starting on left and bottom you would have to put n+1 mod 4, if the pair is left and bottom you use n+2 mod 4, and if the pair is left and top you put n+3 mod 4.

@AdmiralMinell 11 ай бұрын

I treated it as Modulo 4 and I didn't realize putting a digit in the center square would move the wheel. I noticed the 2/3/4 sets would each exclude a wheel modulation respectively. Then I noticed that the wheels in boxes 1 4 and 6 with the "straight" clues could not fall into the modulation with the 2/3/4 opposite the exclusion. So I ended up seeing the polarity principle in passing but I didn't realize its significance.

Some videos I watch and just feel carried along by Simon's logic and he figures everything out miles ahead of me. Then there are puzzles like this where Simon is saying "Thankfully there has been very little in the way of disjoint set" all the while, if he just looked at the disjoint set, most of his deductions could have been made WAY faster. To be fair, I've always found disjoint set sudoku puzzles to be really easy while Simon started the video off admitting that he finds them terrifying.

@tomm35 11 ай бұрын

I went through each of the wheel trios (green, purple, and orange in the video) and assigned them a value based on possible final position to them (i.e. 159=A, 26=B, 37=C, 48=D) and found that each of the wheel centers could only be two from the four final positions. I ended up with R5C8 being AC and got to pencil mark 26 above and under it (same as Simon did), which removed the B option from R2C8 leaving it with only one possible final position and it all unwound from there.
