Three Little Boxes
(Published on 7. July 2022, 18:38 by Al Fresco)
Rules
Fill each box with digits from 0 to 9. Digits cannot repeat in a box.
Grey cell digits must be the sum of all white cell digits that share the same row or column. E.g. R2C1=R1C1+R3C1+R2C2
Good luck and happy puzzling
Solution code: Row 1 from each box reading left to right. 9 digits. No spaces.

Sorry for the long delay in replying here. Thank you all for the kind words. @CHalb Yes I came up with the rules. I've been considering making a full size sudoku with the same rules, however I have been sidetracked with work and other puzzle ideas.

Impressive elegant ruleset. Al Fresco, is this ruleset your own invention or where did you find it?
