Hey, Are You Awake?
(Published on 7. August 2022, 22:06 by mathpesto)
Fittingly, I worked on this over the course of many nights when I should have been sleeping! It's my first time incorporating heyawake rules into a puzzle; I had a lot of fun constructing it and I hope you have fun solving it! If you'd like any hints, feel free to post a hidden comment below or message me on Discord.
Rules:
Place the digits 0–8 in the grid so that no digit repeats in a row, column, or region. Each cell belongs to a rectangular region, which can be made up of 1–9 cells. A number in the top-left corner of a cell gives the sum of the digits in that cell’s region. A digit in a circle gives the number of shaded cells in that cell’s region. A digit in a square gives the sum of the shaded cells in that cell's region. Shaded cells may not be orthogonally adjacent, and non-shaded cells form a single orthogonally connected area. A straight line of connected non-shaded cells may not span across more than two regions.
I created a reference sheet for killer sudoku sums for the digits 0 through 8. If you'd like to use it while solving, click here.
Puzzle:
Solution code: The digits of the shaded cells in Rows 1, 2, 3, and 4 (left to right, no spaces)

This has been on my list to come back to for a while, as I kept getting close but breaking it. Eventually worked out the incorrect assumption I was making - I have a weakness for puzzles that include zeros :) - and was satisfying to finally complete!

This was very nice and very challenging. And solvable by logic... step by step, no trial and error necessary! If I hadn't made so many mistakes on the way :D

Very nice construction! I'm experienced in Heyawake, but not very strong in Sudoku, so this took me exactly 100 minutes to solve. My favorite deduction was R6C4.
