The 69 Sudoku

[@scruffamudda6306]

Thank you so much for featuring my puzzle and for the kind words of praise! This is my 2nd on the channel and I must admit that I had you in mind, Simon, as I was setting the puzzle. I often hear you comment on the beauty of symmetry. The inspiration also came from seeing a puzzle by Bremster (Walk Without Rhythm) which is also 180° rotationally symmetrical.

[@kathyjohnson2043]

Amazing Puzzle!

[@NiennaNeryam]

I totally agree with this! Took me 45 minutes and I didn't have to cheat off Simon once :D So much great logic!

[@TheGrandUser]

At 27:10 why did the cage have to be a 1-5 combo and not a 1-8 combo? I think you got lucky there.

[@karlmortenlunna2417]

Yes, he was lucky. But at that point the cage in r4c23 had to be a 6-cage, and it had to be 1+5. And that places the 5 in r5c9.

[@Samhain_III]

You can do the logic he did later from the left side of the grid. r4c2 has to be a 6-cage (by rotation) without a 4, which means a 1-5 combo. This removes the 5 from r4c9 and therefore this is an 8. That makes the cage a 1-5 combo. But since he did everything later he really got lucky or had his "uniqueness argument" in the back of his head for the left side of the grid.

[@DisturbedNeo]

He already knew the r5c1/2 cage had to be a 9-cage (uniqueness forced the 7), so the r5c8/9 cage had to be a 6-cage, eliminating the 8.

I think a tongue-in-cheek title is perfectly apt for this puzzle given how playful it was, particularly some of those initial deductions. I went down some very wrong paths myself (starting with thinking that the rules also required 6 and 9 digits to have rotational symmetry, which very quickly caused difficulties) but it was incredibly enjoyable.

[@eXaltedBaldGuy]

I just get so happy every time Simon figures things out.

[@RL-gl8qg]

Okay, haven't looked at the puzzle yet, but as someone with severe dyslexia, I can tell you that 6 actually is 9, as far as I can tell, 6 times out of 01. Now I'm going to try the puzzle. Let's see if the dyslexia helps. Verdict: Well, it didn't hurt. Fun puzzle!

[@GregJonson]

I spent 62 bloody minutes on this. I started by checking all squares that could _not_ contain a 9 and I was basically able to put three 8-9 pairs in the top three boxes right from the get-go. That really made the solve easier once I started the actual intended logic, but that by itself took me way too long.

[@kevinlim3395]

That title seems intentional. Nice.

[@tedg1278]

At 20:10, Simon: "Where am I meant to be looking now? Is this obvious to other people?" Yes! You just said it a little while earlier, whenever you complete logic on 1 side check the other side for the symmetry to see if solves it for you.

[@RasperHelpdesk]

Think you got lucky at 27:10 r5c8 was certainly 1, but r5c9 could be 5 or 8 at that point

[@toothgnash]

Yeah - pretty sure he just needed to see that the 6-cage on the left was a 1-5 in order to disambiguate the 5-8. I expect it was meta-knowledge since (as he said earlier) he was certain it'd need to be a 6-cage. If it had been a 1-8 then the corresponding 6-cage on the left would have made a deadly pattern with the 2-4 below it.

[@Trottah]

Noticed this too. If he subconsciously used uniqueness I can forgive Good Simon that transgression. But in that case just use it from the start!

A challenge for anyone but doable for everyone. High praise from me. Hope that counts for something.

This was a great puzzle and video. I really enjoyed solving the puzzle mostly without help from Simon - just a nudge here or there.

[@BobDylan530]

You didn't need it to solve the puzzle, but a neat bit of logic that I ended up finding is that, because the two cages in Row 5 must be different from each other, whichever one is a 9 cage can NEVER be a 4/5 pair, because it would break the opposing 6 cage

[@WheatGrinding]

nice

[@stevieinselby]

That was a really fun puzzle! But an Oops Moment at 27:15 ... why can't the cage in r5b6 be a 1-8 pair adding up to 9, opposite a 2-4 pair in r5b4 (apart from the uniqueness dilemma)?

[@WszystkoZajeteOMG409]

I dont know too and Im curious also.

[@stevewithaq]

I can tell you because I accidentally put a 1-8 into that cage. That puts 465 in r4b6 which means you can't put values that add to 6 in the cage in r4b4 (you end up with 1,2 which add up to 3. But you have to because the opposite cage in r6b6 is a 7,2 pair which = 9.

@27:10 I don't understand how the 58 pair in column 9 was resolved. You said r5c9 had to be a 5, but why couldn't it have been an 8? I know it wasn't because it would cause a deadly pattern in the rotated cage with the cage at the left of row 7. But uniqueness isn't a good reason.

[@sanabas1]

It was a lucky mistake, but there are multiple ways to immediately get that 5. e.g. The 27 just placed force 4 into r6c1, which makes r5c12 a 9 cage, which makes the 1 in box 6 part of a 6 cage. Or the unmarked box 4 cage must now sum to 6, must be 15, and that puts 8 in r4c9. Or where can 5 go in r5? All the other options either already see a 5 or immediately give an unfillable cell.

Normally my time is ~1.5-3x simon's time, when the puzzle is "approachable". However, this one took me a solid 2.5 hours of on/off looking... I got stuck in SO many places where I just couldn't figure out what was helpful. I ended up needing to pencil in 80% of the grid, and just look at the boxes and say "can this really be a 1", etc. to slowly narrow down the possibilities for the cages. I am about to watch Simon so maybe there were some serious strategies I was missing!

[@adilsanaulla7787]

It wouldn’t work because then no place for 5 in box 4

[@CaptianKatsura]

With the pencil marks he had it could have been 1-8, but at that point he already had the cage in the bottom of the box as a 9 cage, making the cage at the top of Box 4 a 6 cage which could only be a 1-5 cage. So he just did things out of order, he had the information necessary to prove that was a 1-5 cage.

[@danielwcrompton]

After many set puzzles on the channel I immediately let set go on the puzzle and discovered that the 2 cel cages in each of the boxes 4&6 needed to be different, which led me to believe that despite 1&5 and 2&4 being valid 6 cages totals and 2&7 and 1&8 being valid 9 cage totals they would likely not be in and box, column or row. I'm not smart enough to figure out the logic here, and I thought it was interesting when I looked at the completed grid and saw I was right. If anyone can point me in the right direction I would be very grateful

I was at least 3/4 done, when I thought I'd blown the puzzle. I had a 9-cage, but couldn't make the matching one a 6-cage. I came back to the video, and watched while Simon confirmed a number of my entries, and shortly reached the cage I couldn't make a 6. Saying it had to be a 9-cage, he did his numbering and I returned to my own. I had somehow blundered into making a 6-cage a 9-cage. I looked further, and saw that I was making two corresponding cages both 6-cages. I have no idea whatsoever what happened, but I resolved my problem by switching a 4 and a 7. I didn't have to do anything else! I finished the puzzle, and hopefully, it's correct. EDIT: Yes! It's correct!

Simon, you really need to pay more attention to colums. You entered the 7 in row 2 17:12 minutes but didn't link it with the 7 in the bottom row until 27:44. "I think that's been available for a while" - yes, 10 and a half minutes previously, lol.

That's an amazing puzzle 😁

If you omit the centre box, you have 105 that has to be in 36 cells, leaving 255 that has to go in 36 cells. Giving an average almost 7,5. So I'm not very surprised that these mostly must be shared by 9s, 8s and 7s.
