Qodec's Killer Sudoku Masterpiece

[@PuzzleQodec]

Predicting the reason for that silly

[@st3phgr1ce]

Not that I could touch Simon’s ability but I kept thinking there might have been something he could have figured out if considering there are 10 cells in columns6 and 7 between the 2 cages so there must be 1 repeat…didn’t get any further than that but it was a thought. ❤

❤ watching Simon solve you puzzle!!

[@Bonehead777]

Yeeikes, that was a brilliant Sudoku. Looked very, very difficult and I wonder sometimes how folk like Qodec construct these without spending weeks on them, but well done.

[@PuzzleQodec]

You're not wrong. This version of the puzzle is one that I made a few weeks ag. Made some other versions.as well. Only last week did I choose the one in the video for LMD, because I saw no way to improve on it any further.

[@DRayX701]

The easier way to see the 123 domino in box 9 is that there is already a 123 in box 8, so only 2 of the 4 123s in the orange area can go in box 8, so the other 2 must be in box 9.

Qodec on a Friday night brilliant.

[@niyazali7983]

No Bobbins McBobbinsface? 😭

[@nsigfusson]

I like Simon, he's a good egg.

[@lancelot848]

I thought a simpler way of getting the idea of the arrows, was that all the low digits in R8 and R9 were done by C7. That meant that R8C9 and R9C9 had to be medium digits and that R7C78 had to have medium/high digits which meant that R89C7 had to both be low digits

[@AcanthaRayneOakMoon]

Qodec's features on the channel are always my favourite, but I might be a touch bias lol

[@Timlagor]

46:20 I feel strangely convinced that the solution is going to hinge on middly digits now

[@Nekromant05]

There are a few ways to see that the two arrow cells in C7 have to be from 123. One of them is to realise that R9C9 sees a 123 and a 789 tripple. So it must be a 456, therefore finishing a sextuple (how often can you say that?) of 456789 in box 9.

[@PaulJimenez3]

I quickly saw that if a 4 is doubled then that means that 1,2,3 are all on the arrows in box 8... which would leave the

[@Archik4]

20:00 row 7 already have 3 123. row 9 and column 9 cannot be 123. So both orange in box 9 should be 123. So 4 cannot repeat.

[@MarkBennet10001]

Too tired to give this one a go, but spotted some things - it looks amazing

[@MarkBennet10001]

Looking forward to R7C6 in box 9 (as already coloured)

[@MarkBennet10001]

Superb puzzle - really nice solve

[@Kirbyfan87827]

Finished in 24:57 by following along with the video.

[@karthick_michigooner7431]

The 4 could also repeat in the orange cells... Keeping the total to 15

[@andymoss]

Mr. Broken Record checking in. Unnecessary colors obscuring box boundaries make another puzzle solve so difficult. To whit around 39:28 with the 9’s.

[@RoderickEtheria]

22:48, Simon, stop forgetting that a single-digit sum made of 3 non-repeating digits must include two of 123. Two of these are available in b8. That means the only options for r89c7 are from 123.

[@Sinisest1121]

isnt Simon made mistake with that cage. He puts corner marking 5 on cage but i think as rule say it is less or equal to 10. This mean 4+6 = 10 is also working. I think he made typo and mean actually 4 not 5.

[@thenickdude]

Luckily he notices at 21:05 before he uses it for any deductions

[@thecaneater]

He typos pencil marks all the time. It's infuriating.

[@coconuts2513]

infuriating is quite strong language for someone merely watching a video solve of a sudoku 😂

[@katiekawaii]

​@@thecaneaterEveryone makes mistakes.

[@Sinisest1121]

@@coconuts2513 i dont see any link to infuriating in any comments here. I just watch these videos on time when i solve same sudoku so i just try to understand all steps why. On moment when i written my comment i was somewhere less than 20 min but now i have solved sudoku and also finished video.

[@stevenape377]

18:44 I think it hadn't been ruled out that apart from the four low digits on the arrows, we could have two fours. Edit: Simon catches it at 20:26. Sorry, haven't said anything, carry on!

[@danielszanto2955]

Not really, as on of the repeated fours would have to be in box9, but that would leave 3 123's on the arrows plus the one in the cage are too many. He used this logic around 15:30, than had forgotten it. If only he would have flashed the orange arrows in box8...

[@HikingEngineer]

I just paused the video -- why do the orange arrows have to have 4 and 5 on them? why can't there be a repeat 4? edit: kept watching and he caught the mistake

[@Timlagor]

20:00 Exactly what I came down to the comments to see if anyone had answered (I'm also surprised he didn't spot the 456 in the bottom right since the other 789 has to be in row 7) ..and the answer is that he quickly realised he made that mistake

[@e7diablo]

Is it just me or have their videos' audio mixing lately been really low/quiet?

[@denisdodelin-m1e]

1:26:08 I don't understand why the 18 pairs in box 4&5 are resolved. EDIT: 8 in R9C2, my bad. Incredible solve & puzzle. Thanks for sharing

[@davidmorrison7742]

Isn't there a second instance of SET in the puzzle? Columns 67 and rows 89?

[@Sinisest1121]

14pair is not working as it forces to plaxe on arrows into box 8 1234 and this mean we have nothing left to place into that 1 cell cage
