In this Quattroquadri some Sums sum Sums, and some Sums don't sum Sums.

Glad you enjoyed, had a lot of fun exploring this ruleset and it's weird implications when setting.

Settled for watching Bremster solve this. These quattro's are just too much for me lol. Nice puzzle by Palfly. Good solve by Bremster.

Ow. Ow. Ow. 😅 This was mind-bending, but a lot of fun! Some amazing deductions to be made (a few of which I was a bit slow on 😛), was able to finish it in 15:45 (conflict checker off). Many thanks to Palfly for an amazing puzzle, and to Bremster for a great solve and presenting it!

Row 4 was the only part I found difficult but it is so well telegraphed that one knows they must focus there. I love the infinity opening and how quickly C1 fills in.

Really nice puzzle!

[@kana2112]

My brain hurts after that one. I had to make several notes, but I got it! Very cool concept for a puzzle!

[@malvoliosf]

24:35 - Your thoughts on row 4 were a little defocused. The point is that the leftmost 4 digits all count double and the row sums to 44. r4c4 and c4c5 must be chosen so that 2 * r4c4 + r4c5 + 2 * (4 + 8 + 2) + 9 equals 44, i.e. 2 * r4c4 + r4c5 equals 7. That means that r4c4 and r4c5 must be 3 and 1.

Really like those Quattroquadri's, done in 13:08.

Brilliant stuff

[@barrycastella]

Nice Solve. Too hard for me. I had to guess a few. Your solve made so much sense

[@TheMNbassHunter]

Pretty happy I was able to solve this one. Got it done in 27:48.

That lying 8 that apparently was "an infinity clue" stops me from doing anything with this puzzle. Thought it was a regular 8 first, but had to stop solving and watch the beginning of Bremsters solve. What does the infinity clue mean? It doesn't say anything about it in the ruleset. Infiniti is as it says an infinitely large number and that doesn't work at all. You can't sum to infinity. I don't understand what Bremster is doing with that infinity clue either. (Give me no clue...) Must be larger than 39. Why? Maximum number? Infinity is larger than any maximum...

15:21. Whoa. The 44 clue was the hardest for me. And I see... it was the hard part for you too 😅 Hope you get better soon! 🤗

[@palfly1864]

@@anaayoung9142 The 44 was put there as more of a disambiguator, there's some interesting logic in the top right box that you can do to get down to 4 cells unfilled before using the 44

24:01 for me nice puzzle
