Quite a Quiet Little Quattroquadri

[@_raumplaner6575]

Some trivia: This was the very first puzzle that used the Quattroquadri grid (to my knowledge). The name Quattroquadri was coined after this puzzle was made.

This flowed beautifully. Loved the puzzle Raumplaner!

[@kana2112]

That was easier than expected! Fun little puzzle.

[@titusadduxas]

12:01 - That was very enjoyable

[@megaminxpll]

Nice & short & not too hard, done in 5:23. Too bad BremSter missed the easy way to disambiguate this, the left black dot had the same parity, so it could only be a 2-4 pair, ie low.

He usually overcomplicates all puzzles with numbers in it. :) Now I have to go and listen to The other son of Odin to regain my mental composure.

Got it in 10:59, nice little puzzle, first quattroquardri for me.

[@bigwibble6]

I too coloured in early on, and then didn't spot the same colour on the left double dot. I had lots of fun doing logic elsewhere until I finally spotted it

[@oldmomj5088]

Nice puzzle. Thank you for the solve

[@barrycastella]

Enjoyed this one. Thanks

Easy sudoku, oops Quattro quadri sudoku. Solved it in 4 mins 48 secs and felt relaxing

[@laszloliptak611]

[@kevinerose]

Nice. I got 10:19

9:25 for me nice puzzle

[@anaayoung9142]

6:22. I find the colours then the pairs, 19, 28, 37 and 46, the one that I started. Then I find highs and lows. But I could've solved with the black dot.. that both of us didn't see it 😅

[@iuriikononenko9238]

I got color on lines in little different way (box 3 affecting polarity on little wishper, which affected different polarity on black dot in box 4). And the easier way to solve for low/high was definitely noting a black dot having 2 digits from same polarity (in box 1-3).

[@praematura]

Nice puzzle, even if I broke it with a mistype and had to backtrack a little! 😅 Done in 5:58 (conflict checker off), many thanks to Raumplaner for a great puzzle and to BremSter for presenting it!

[@RADZIO895]

28:11 for me,. After 24 minutes I realised I must've done something wrong, because I got stuck on a contradiction, reseted the entire puzzle, decided to use different coloring and that solved the entire thing in the remaining 4 minutes

[@drengskap]

I must be getting more used to quattroquadri, I solved this in 13:22 which was fast for me.

[@GianniBergandi]

4:16 for me, very cool !!

[@AndreAy1975]

Solved it in 00:11:44.

[@donaldsnyder1543]

13:22 with about 8 minutes of video help. I'm still not good with these quattro's , they are quite foreign to me. Nice puzzle tho . Good solve by Bremster.

That was painful, my brain is slow, too cold.
