Thanks for featuring my puzzle! I'm glad you enjoyed it! I've been enjoying Quattroquadris since the concept was invented. I've made a whole bunch and published a few of my best. I think this is the first of them I've seen solved somewhere.
Very interesting in how it forces you to chuck out a bunch of the usual logic you'd use in sudokus! Also I'm glad I'm not the only one that forgot the parity rule at the end. :)
Oh my that was a tough puzzle. Never did anything like that before. Had to restart a few times so think I was around 50 minutes or so. Cool puzzle tho. Had to watch a bit of the video as well to get my head around it. Nice job by Bremster on solving.
amazing solve, absolutely puts my pitiful 88' attempt to shame i would never have thought about looking at 5's, i was very much focused on the kropki in box 2, trying to prove that it couldn't be 3:6, then accidentally proving that it must be 3:6 and trying to disprove the other cases, mostly through a lot of bifurcation, the refuge of dumdums like me... thanks for the lesson, i will try to remember to look for what has to go on a line, i really want to get better at these, but based on my times it will clearly take me an eternity to do so
I've done over a dozen quattroquadri puzzles, and they still wreck my brain. 😄 Took a moment to find the break-in, then went relatively smoothly and finished in 9:06 (conflict checker off), many thanks to Oddlyeven for a very cool puzzle and to BremSter for presenting it!
The other way to get the parity of the last line was to see the only remaining positions that the 5 could go, and notice that every position forced the same parity. Really liked this one.
17:10 for me, but to be honest I guessed at one point. Made a mistake, wasn't super commited to finishing the puzzle and almost quit it, but decided to just quickly try fixing the mistake with just intuition rather than any logic and it worked out

I really hope I get more of these. I loved the concept and I want to see more of them using different constraints and different ideas.
What a great puzzle and so different with that 6 of 9 condition. Thanks
Thanks for bringing this to us BremSter, so different and enjoyable to work thru

Nice puzzle, relatively easy. Solved it in 12:34.
COMPLETELY forgot about the alternating parity rule! I think the puzzle is otherwise unsolvable.
This took me ages, but I'm still amazed that I managed to do it at all!
Can't say I expected to be able to do this. WOW!
One of the most amazing puzzles. SO cool to see innovation still happening in Sudoku.

Loved this puzzle. Took me a while but was really happy i worked it out.
That was different. Cool logic, but I'm not sure I like how it was only a 6x6. Really threw me off.
28:13 for me
nice puzzle and solving
Done in 8:53, in the end there was only one digit that could go in r6c5.
The other way to get the parity of the last line was to see the only remaining positions that the 5 could go, and notice that every position forced the same parity. Really liked this one.
I enjoyed the puzzle and the solve.
Interesting ideia. I like it 😊

The blue in the number and the purple in the renban always disrupts me. I wonder if Bremster has the same color issue.
Nice puzzle
You missed the given 4.
