Sudoku Constraints in a Fierce Debate

[@douglasplachy4577]

Thank you! This is by far the most enjoyable Sudoku that I’ve ever solved. I’ve done 100’s over the years, but nothing like this. Interesting rule set. I clearly missed some early logic, but I got it in the end. I am a “Cracking the Cryptic” loyal viewer, but subscribed today to your channel after this great puzzle. Again, thank you!

That was cool. I've never done anti-quads before. I love how well they worked with the quads.

00:24:10 - I really liked the interaction of quads and antiquads! Thank you very much!

[@JohnRandomness105]

At one point, I realized that the 2468 anti-quads required four of the five odd digits. With one of them, the 123 quad only had one cell next to the anti-quad, so that cell was 13, the other of 13 was away from the anti-quad, and 579 were in the other anti-quad cells. With the 1359 anti-quads, they had to have four of the even digits and 7. 7:40 Where do 569 go in block 4? Then where must 7 go? 9:40 In block 1, one of the 2 and 7 must go on the anti-quad. The other is away from the anti-quad. That leaves 468 for the rest of the anti-quad.

There must be two sets of 2468 in rows 7 and 8. One set goes in box 7. The other set must go in columns 6 and 7. Similarly with 1359 in rows 2 and 3, which must go in box 3 and columns 1 and 4.

...and since that's 4 digits that have only 4 cells they can go in those rows, each of those 4 cells MUST hold one of the otherwise-excluded digits. Nice.

I enjoy your channel so much! I appreciate how much you like solving these puzzles and want to share that with people. Thanks.

Love this thumbnail! 😅 14:57 colouring evens and odds! Quads are nice!! 😊

[@StGordo61]

Thought it was going to be easy with so many bubbles…..wrong! Required lots of thought and process, loved it! Thanks BremSter

I think quads are my favorite constraint. Anti-quad felt really nice to do along with regular quads.

17:28, nice ruleset!

[@praematura]

Loved this puzzle, was a lot of fun! The interactions between the quads and anti-quads was really nice, finished in 15:04 (conflict checker off). Many thanks to The Bard for a cool puzzle and to BremSter for presenting it!

11:59 for me, very cool !

[@kamilporadzinski2018]

17:52 for me today. Excellet new concept of quads.

[@pokinDave]

if you look at rows 7 and 8 the even digits are hard to place. So even / odd coloring might have made this a bit easier to solve. Well done overall

[@roelrijkens4061]

Really fun puzzle.

Never saw anti-quad before. Settled for watching Bremster. Neat puzzle though. Nice solve.
