After a longer break, I am back to setting puzzles. Enjoy!


Rules:

Sudoku: Place the digits 1-9 exactly once in each row, column and box.

Region Sum Lines: Box borders divide blue lines into segments. The digits on each segment of the same line must sum to the same total.

Renban: Digits on pink lines form a non-repeating, consecutive sequence in any order.

You don't need to put an 8 in R7C9—just a few steps of testing show that R5C3 can't be 8, and the puzzle falls into place. That said, I'm not really into guesswork. It's a beautifully crafted puzzle though

Really lovely puzzle! I think I got it right, confirmed by the software, but row 9 as solution code was wrong. Weird, but thank you!

Thanks, I had indeed messed up the code.
