Fillomenon
(Published on 2. October 2023, 19:14 by DarthParadox)
Divide the remaining cells (outside of the nine boxes) into orthogonally contiguous regions and fill them according to Fillomino rules: every cell contains the size of its region, and no two orthogonally adjacent regions may have the same size. No Fillomino region may be larger than nine cells. The clues outside the grid give the sum of the Fillomino digits in the indicated row or column. (Sudoku digits are not included in the sums.) Additionally, a Fillomino digit must not be orthogonally adjacent to an identical Sudoku digit.
Clues inside the grid begin hidden by fog; the fog clears when correct digits are entered. Digits along an arrow must sum to the digit in the attached circle; all arrows have single-digit sums and do not branch over overlap. Digits separated by a white dot must be consecutive, and digits separated by a black dot must be in a 1:2 ratio; not all dots are given. The purple lines contain a set of consecutive, non-repeating digits in any order.

I was looking for masterpieces in somewhat older puzzles and for sure here I found one

Wonderful puzzle with several neat deductions, thanks!

You won't believe what's happening in this puzzle until you witness it by yourself... 95% is an absurdly low rating for a puzzle like this.

Pure madness.

I love puzzles like this. More than six hours for me.

I absolutely love these sorts of puzzles that intermingle puzzle types, and this was one of the most fun (and tricky!) of them I've ever come across. Absolutely loved it. And despite the steady difficulty, I never felt stuck and there were often multiple places I could regain my footing. Thank you for making it!

Magnificent puzzle! Thank you.

Amazing. Just, that's all that can be said.

Absolutely beautiful. I kicked, I screamed, I wasted an hour with the grid halfway filled because I can't count to nine, and I spent the whole time in awe of the construction, which made me feel very clever about 10% of the time and incredibly stupid the rest of the time. Thank you!

Brutally difficult but with tons of fantastic bits. There were moments that made my jaw drop with their subtlety. I would've thought this would be one of those puzzles that eased up after the break-in... but this kept me befuddled the entire way.

Very nice!
Difficulty is hard to rate sometimes. This one is a fairly smooth solve throughout without any fiendishly difficult deductions, but it's got a whole lot of moderately tricky ones, so it'll probably take a few hours.

The most difficulty one I ever solved. It took me more than 2 hours. Very NICE! Spoiler alert!

This is mad! Very very mad!

That was insane, very challenging but super enjoyable!

I found this extremely, extremely challenging.

Beautiful, intricate, challenging, and most of all fun. Thank you so much for sharing!

Fantastic puzzle. Failure to read the rules properly caught me out again. Was completely stuck about 1/3 of the way through, until noticing "Additionally, a Fillomino digit must not be orthogonally adjacent to an identical Sudoku digit."

I really enjoyed solving this puzzle which lives up to its name. I've no idea how anyone has the mad idea of mixing fog, deconstruction, Sudoku and Fillomino - and to get good interplay between the rules in a way which doesn't feel forced: that is some setting.

The adjacency constraint is orthogonal only. Updated the rules to clarify.

Nice concept and a very fun puzzle!

Does fillomino/sudoku adjacency include diagonally adjacent?
