The first time I saw a Partiti was at the World Puzzle Championships 2017 in India. I think it's a very nice puzzle type. I hope you like it as well :)
Rules: Place one or more of the digits 1-9 in each cell, such that the number in the top left corner of some of the cells is the sum of the digit(s) entered in that cell. Digits in a cell must be unique and same digits cannot be placed in cells that touch each other, not even diagonally.
The puzzle is also available on Penpa.
If you get stuck you can find a hint here.
Solution code: All the digits in row 4 and column 4. Give the digits in ascending order when a cell contains multiple digits.

I really enjoyed this puzzle! Hope to see more of them:)
I found it way easier than 4 stars (but that might be because I spotted the trick you wrote in the beginning of the hint (which I checked after I finished solving) quite fast) - so I would definitely recommend trying it, even for those who don't usually solve 4 stars puzzles.
@karen_birgitta: I'm glad you enjoyed the puzzle :) If comments are positive like yours I'll surely make more of them :)
