Normal Sudoku rules apply. Digits cannot repeat in cages. Digits cannot repeat along the two main diagonals, marked with thin blue lines. Blue lines are divided into segments by 3x3 box borders. Each segment along a line must sum to the same as all other segments on that line.

Fun coloring puzzle, 3s broke fast then I hit a bit of a wall and had to color out the puzzle, then all the digits resolved nicely at once.
