This is my first attempt to (intentionally) create a hard puzzle. To me a 3.5*-4* with fun to find interactions. I hope you enjoy solving. Let me know how you like it.

Rules:

Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box.

Palindrome: Digits along the gray palindrome line read the same forwards as backwards along the line.

Region Sum Lines: Box borders divide each blue line into segments of the same sum of values.

Entropic lines: Any set of three sequential cells along an peach entropic line must contain a low digit (123), a middle digit (456), and a high digit (789).

Killer-Cages: Digits in cages cannot repeat and must sum to the value shown in the upper left corner of the cage.
