The rules are as follows:

• Sudoku: Normal Sudoku rules apply.
• Killer: Digits in Cages cannot repeat and sum to the given total.
• Region sum lines: Digits along a line sum to the same total in each 3x3 box the line visits. Different lines may have different sums.
• Palindrome lines: Digits along a line read the same forwards and backwards.
• Every line in this grid is a region sum line and a palindrome line at the same time. Digits may repeat on lines if allowed by the other rules.
• For clarification: two lines cross each other in box 8: The line starting in r9c3 ends in r4c7. The line starting in r3c7 ends in r7c9.

Since my first puzzle was called "all about 30", I had to include a small nod to "30" again.

In terms of difficutly, I would rate it at ~3.5/5.

Have fun :)
