Special Thanks
Thank you so much to Palpot for their guest spot last week, contributing an excellent puzzle to the series. I look forward to a return to Dutch Neighborhoods in the future *fingers crossed*.
Dutch Flat Mates (Hit Points) was constructed for Scojo's weekly prompt, which specified using this constraint in a puzzle, who in turn cites a puzzle on the CTC discord for inspiration, which you can play here:Hit Points - By Walker .

Hit Points Example
Clues on the outside count the sum of the digits in their correct position from that direction. In this example all side clues are given.

In Row 1, from the left (yellow), the digits '3' and '7' are the only digits in the correct column position, and have a sum of '10'.

In Row 4, from the right (cyan), the digits '2' and '9' are the only digits in the correct column position, and have a sume of '11'.

The constraint applies similarly to clues on the top and bottom of the grid, but for digits in the correct row position from that direction.

Hint 1 - Something to ponder

The maximum possible sum of clues on each side is '45'.

The 3 clues interact with the 5 clue, which in turn interacts with the 10 clue.

Don't forget about 1s, 5s and 9s; and what could almost be considered a negative constraint with oversumming.
