Normal sudoku rules apply.
Entropic lines: Every group of 3 digits along a peach colored line must include a low digit (123), a middle digit (456), and a high digit (789).
Modular lines: Every group of 3 digits along a teal colored line must include a digit from the mod 3 groups (147), (258), and (369).
Quadruples: A digit in a white circle must appear in a surrounding cell.
Solution code: The digits of row 6 and then row 7, left to right.

The break-in was nice, then it was standard use of the lines properties.
Good puzzle

Small revision to rules for consistency.
i.e. changed (1, 4, 7) to (147), etc.
