For this fourth puzzle, I was originally experimenting with X-Sum clues and I found some nice properties that they had. Hence, I had to make a puzzle with them.

Rules:

• Normal sudoku rules apply: fill each row, column and box with all digits from 1 to 9.


• 3-whisper lines : Adjacent numbers along a cyan 3-whisper line have a difference of at least 3.


• Renban lines : Numbers along a purple renban line form a set of non repeating consecutive numbers in any order.


• Palindrome lines : Numbers along a grey palindrome line read the same forwards and backwards (i.e.12 56 56 12 would be a valid palindrome line but not 34 43).

Here is the puzzle:
