March of the Quads: Too Hot To Handle

[@stagglynp]

at 20:33 why couldn’t the 9 in box 3 be in r2c9?

13:29, feel like I never got stuck and made steady progress the whole time. I'm usually not a superfan of quads but this series is having them grow on me!

Nice puzzle and solve. Solved it in 19:05.

[@megaminxpll]

Took me 15:41 to handle this one. @20:32 that was a lucky error.

[@adrianhead6272]

Ignoring both pencil marks and plain sudoku, and then gets lucky to boot - poor solve all round.

A nice challenge, an had a small improvement on time: 34:28 vs 26:21 (conflict checker off). Needed some careful examinations of the thermos and noting a few key pairs, triplets and quads in rows 7, 8 and 9 to help reduce options. Really nice puzzle!

Love the puzzle

[@kana2112]

Cool puzzle, but there was so much going on!

[@buzzard6410]

Absolutely loved this puzzle!

20:34 What am I missing? Why can't 9 be in r2c9? And therefore not only in r2c1 - but also in r3c1 and r3c3? Edit: found the way - spoiler ahead! We have the 9 in r1c6, the only place 8 can go in that box is into r1c4. Because of the 3 in r4c5 the only place for the 3 in box 2 is in r2c4. Look at c4: We have an 8 and a 3 in r1 and r2. Therefore r6c4 must be a 1 and that excludes the 1 from r7c1. Now look at r6 c1 and c2:: Where can the 8 go? If the 8 goes into r6c1 only 3 is left in r7c1. But the right thermo in box 7 now has the lower digits with 6 in r6c2, 5 must be in r7c3 because of the quadruple constraining the 4 and the 3 already placed. With the 2 above that 5, the 3 and 4 to the left of the 5 in box 7 only one digit is left that is lower than 5 and that is 1. And 1 cannot be placed on a thermo except in the bulb. Therefore r6c1 cannot be 8 but must be 6 and we know which thermo ends in the higher digits in box 4! 😊 01:15:55 including backtracking and writing this comment ...

Thanks for explaining, I think though in the video solve it's not clear that the full deductive path was followed (not a ding on Bremster, I think it was just a mis-scan) thanks for explaining

[@susanne5803]

​@@elosf Thank you!

44:20 a bit tough for me. Very cool puzzle tho.
