I made this puzzle for an impostor prompt on Scojo's Twitch stream

Normal sudoku rules apply: Place the digits 1-9 once each in every row, column and 3×3 box.

Little Killer: Numbers outside the grid are the sum of the digits pointed to along the indicated diagonal. Digits are allowed to repeat along those diagonals as normally allowed by other rules.

Modular Lines: Teal lines in the grid are modular lines. Any three adjacent digits along a modular line have a distinct remainder when dividing by 3. Digits that share a remainder are (1, 4, 7); (2, 5, 8); (3, 6, 9). Digits may repeat on these lines if allowed by other rules.
