Preamble
-
Not much information regarding this puzzle, between 1 and 2 stars for difficulty, put at 2 but fully expecting it to not remain there. Been quite busy recently so haven't had chance to set harder/more mathematically involved puzzles, but more will come...
Let me know what you thought of it in the comments!
Happy solving!

Rules:
- Normal sudoku rules apply.
- Digits in a marked killer cage cannot repeat and sum to the marked total (if given).
- Digits along a green 'German Whispers' line differ by at least 5.
- Digits on a purple 'Renban' line do not repeat and form a set of consecutive digits, in any order.
- Clues outside the grid give the sum of the first X cells, where X is the cell closest to the clue.
- Digits on a grey square are even.
- In this puzzle, some totals have been obscured. Some have been replaced with a 'p'. 'p' is not necessarily the same for all sums, and 'p' stands for 'prime number'. A prime number is any number that only has 2 divisors, itself and 1. Some totals have been replaced with inequalities.

3 stars difficulty for me. 18 digit answer codes are frowned upon as far as I can tell. Cool puzzle thanks!
