** TODAY'S PUZZLE **
Scojo featured on the channel a couple of weeks ago with his favourite puzzle but many of you have suggested that your favourite Scojo sudoku is this one: Kingsroad. It's certainly a bit easier and contains some wonderful logic and plenty of opportunities to kick yourself too!
Play the puzzle at the link below:
sudokupad.app/6ul7danidn
Rules:
Normal sudoku rules apply. Cells touching diagonally cannot contain the same digit. Lines in the grid act as both Region Sum Lines and Parity Lines. Along a Region Sum Line, box borders divide the line into segments with equal totals. Different lines may have different totals. Along a Parity Line, digits must alternate between even and odd values.
Jane Street's Bug Bytes puzzle is available here:

What a nice surprise! I just watched back my setting stream for this puzzle and my exact words were "I think this was a successful setting thing, I mean it's not the best puzzle I've ever created, but I think it's interesting [...] Not one I expect to get a CTC feature or whatever..." Shows what I know! Your solve was excellent Simon, thanks as always for solving my puzzles!

A generalization of parity deductions on this puzzle would be: look at boxes with even number of line cells, if the number of pairs of line cells is odd, the sum is odd, if the number of pairs is even, the sum is even.

These combinations of variant rules can produce some real beauty and interesting interactions, even when the overall puzzle is not complicated. The king's move did a lot of work (and I love chess puzzles). I will put this one on my list. Thanks, Simon, as always.

Hello Simon, We are Maria and Iryna from Kyiv, Ukraine, and we kindly ask you at 23.05.2024 to tell your "Happy birthday" to Roman, who is son of Iryna and fiancee of Maria. Roman likes to watch your videos very much, and this video is very often the last one he watches at night before going to bed. Because your videos really have the effect of an evening fairy tale: everything starts with an intrigue and it is not known how the events will develop, but you can expect a happy ending. Also it will be perfect if you add "We are proud of your successful career in 3D engineering and hope you to stay comforting, reliable and kund person" as he is in everyday life. Thank you 🙏

@chocolateboy300 12 дней назад

I finished in 93 minutes. This one took a lot of staring and calculation. I must have stared at the puzzle for half my time after I had already done the parity. Realizing the connection between box 1 and box 4 was a light bulb moment for me. I slowly figured out the minimums and made my way to victory. The geometry of this puzzle was very nice. I wasn't expecting that box 2 was how I broke through after concentrating so long on box 1 and box 4's lines. Amazing job. Great Puzzle!

@hellstorm42 13 дней назад

*6 unfilled digits remaining* Simon: I shouldn't say it but I feel like this is finishing for me. 😂 You don't say?

@Anne_Mahoney 13 дней назад

It's been observed before that Simon will say he thinks he's getting close to the end when he's got fewer than 8 or 10 digits to go, and Mark will say he thinks he's finishing up after he's placed the first one or two. 😹💛

@roberickson93 12 дней назад

Took me much longer than it probably should have. I was figuring out parity as I went instead of doing it all at the beginning so I missed some of the deductions that were more obvious once the parity was in place. First time commenting, but I've been watching for months! Thanks for your dedication to logic!

@H0lyMoley 13 дней назад

I never even thought of going through the parities, which I guess made my solve way way way longer than it needed to be! 58 minutes for me. Spoiler... * * So I started off by working out that the minimum number you can get in the seven-length line (box 4) is 28 (1+2+3+4+5+6+7) and the maximum you can get in the four-length lines (box 1 and 2, which must have the same total as box 4) is 30 (6+7+8+9). However, if it IS 30, boxes 1 and 2 won't work (since there's no way to put in the even numbers correctly with the king's rule). Therefore the line going through boxes 4, 1, 2 and 5 must have a total of 28 per box. ...Yeah, that's the long way of doing it. Bearing in mind that I hadn't worked out the parities of anything yet (I think I started with the deduction that Simon made at about 21:00, and then worked out that there had to be four odd digits in box 4 on that line, therefore making the parities on that line trivial.)

@anaayoung9142 13 дней назад

This puzzle take me almost 38min, but it was very worth it! My main problem was forgeting the king's move rule 😅 after I remember that it got a good flow! Thanks 😊

@iuriikononenko9238 12 дней назад

Simon definitely likes reverse logic! Sum of two digit with different parity would always be odd, thus the single digit is odd, and here we start with parity

@Yttria 14 дней назад

Nice, fun approachable puzzle. Finished in 37:45 after forgetting the parity line rule for 5+ minutes.

@thebitterfig9903 12 дней назад

That was a very fun puzzle. Took a second to get into the swing of things, using the King's Move to rule out certain number placements and combinations, but then it starts to flow. A really lovely solve.

@WimmekeVL 13 дней назад

I didn't start at the bottom one, but at the top left where I deducted the same thing with 7 digits leading up to 4, and eventually 5. Then I started thinking about the secret, deducting that the remaining 2 digits had to be either 15 or 17, after checking the lowest thing the 7 digits could add up to, and the highest thing 4 digits could add up to. But that never got me anywhere. I should have stuck with parity distribution.

@ericpraline1302 12 дней назад

@srwapo 13 дней назад

26:53, surprised how quickly this one went for me, especially considering I put the puzzle down for a little bit and "remembered" the rules as being anti-queen when I came back to it and had to undo some work.

@TheDingus42 13 дней назад

As a very amature puzzle solver it was a good feeling to solve this one without following Simon's break in steps. I'm just annoyed that I completely forgot about the region sum line part of the rules after using it to get the top boxes mostly done

@henriknobinder7395 12 дней назад

So when I sat down with this puzzle for the first time earlier today, I don't know what I did, but I suddenly realized that r4c5 had to be a 2 before I had put in any other digits, and got a whole lot of deductions as a result of that. And soon after that, my brain went "Noooooooo, what are you doing? you don't know that's a 2! HOW DO YOU KNOW THAT'S A 2???" and I completely lost my focus and put the puzzle away. Decided to try it again now, and this time, my solve was much closer to how Simon approached it. Weird.

@Urutsini 13 дней назад

33:15 It's amusing that Simon forced himself to find another justification to put a 2 in R2C9 rather than just use the logic he just uncovered that meant if the 2 is in R3C9 then that would put too many odds in Row 2.

After it I watch the video (or sometimes I start watching, if I look on it for an hour without get find a piece of the puzzle). And I think "Why he took so long, doesn´t he see r9c3 can´t be a 9 anymore." (at 24:30) BUT: You needed around 32 minutes. I needed 1 and a half hour. Also I noticed very early (around 3 minutes) r3c5 and r6c6 are same digits, cause they were only digits not on a row in both boxes.

After, at 31:07, he tries to claim it was simply a missclick. However, I have trouble believing even Simon can accidentally press a 2 when going for a 6 🙂. I'd put it down to momentary carelessness, due to going too quickly. He was just expressing the thought that "sometimes these odd-even parity puzzles ... can go quite quickly". I guess he was attempting to demonstrate just how quickly they could go - and as a result, he slipped up. At least he caught it fairly quickly.
