Battery Pack, by James Sinclair
Normal sudoku rules apply, and all clues are standard.
Region sum lines: box borders divide each blue line into segments with the same sum.
German whispers: along green lines, digits differ from their neighbors by at least 5.
Renban lines: purple lines contain a non-repeating set of consecutive digits in any order.
Digits in cells with a shaded square are even.

I'll tell you what, once I stopped being an idiot and putting odd numbers in the squares, it all came together wonderfully. Thank you!

Tricky mid game. On the lower half of 3 stars for me although I always struggle with quadrangular symmetry. Could be 2 if you are used to it.
