Initial Setter Difficulty: 2 / 5
Mean Mini Sudoku
Select six unique digits from 1–9 and place them once each in every row, column, and box.

Dutch Flats
Every 5 in the grid must have a '1' directly above it or a '9' directly below it. It may have both, but it doesn't need both.

Target Sums
A clue X outside the grid indicates the sum of all the digits that appear in its row or column before reaching the target digit X (starting from the end with the clue).

Killer
Digits in a cage may not repeat and sum to the small number in the top left corner of the cage.
Hint to start

Target sums give us 8 and 9 as included digits, and where can 9 go in Box 3? 8 can then be placed with consideration that I won't spoil.


Solution code: Row 6 Digits

Really glad to see the 'pick your own digits' constraint becoming more mainstream, and it worked fantastically with the flat mates rule! Great puzzle <3
