Sticky Notes, by James Sinclair
Divide the grid into six orthogonally-connected six-cell regions, and place the digits 1-6 once in each row, column, and region.
Each region has a corresponding color. A note outside the grid indicates that the region of that color contains a run of one or more orthogonally-connected cells (bounded on either side by a region border or the edge of the grid) in that row or column, and the number in the note (if given) is the sum of the digits in these cells.
If a region contains multiple sets of orthogonally-connected cells in the same row or column, a note only applies to one of them.
When notes overlap, the note on top has a lower sum than the note immediately below (this applies even if a sum is hidden or not given).

Originally published in Artisanal Sudoku, Volume 211. Thanks to Michael Lefkowitz for help with the visual design!
I'm setting the initial difficulty at 2* because I prefer to round up, but I won't be surprised if it winds up at 1*. Check back here later this week for two more (larger, tougher) puzzles with the same ruleset.
Lösungscode: row four, with a dash ("-") to indicate each region border

At first, I read overlapping rule in reverse and spent an hour til I realised that. After that the solution was smooth.

My brain hates chaos construction, but I successfully pulled it off.

I really liked that the logic I needed to use felt very different from what I know from other chaos construction puzzles!

Fun little puzzle, looking forward to seeing the larger versions.
Also 'grid' in the rules is a strong word for a wonky set of sticky notes... :D

It had a kindergarten feel, very enjoyable, but definitely a 1 star
