(Published on 17. May 2023, 20:00 by Jobo)
Hello, enjoy this puzzle!
All feedback and comments will be much appreciated!
Rules:
- Normal sudoku rules apply.
- Digits in cages must sum to the small clue in the top left corner.
- Digits separated by a white dot must be consecutive. Not all dots are given.
- Diamonds with a given digit in the center are region sum lines. Digits along these diamonds must sum to the same value in each 3x3 box the line passes through.
- Diamonds without a given digit in the center are renban lines. Digits along these diamonds are a set of consecutive, non-repeating digits in any order.
- Every diagonal of length 8 must contain at least one 8.
Solution code: Row 3 followed by row 7.

Very clever, love the interaction of the given digits with the region sum lines.

I would have finished it sooner had I remembered that final rule earlier! Once I did though, it fitted together nicely.
A very clever and well-crafted puzzle. Thanks for setting.
