Modular Penpalindromes by Cygne

Rules

• Normal Sudoku rules apply.
• Digits along a gray palindrome line read the same forwards and backwards.
• Any group of three adjacent digits along teal outlined sections of a palindrome line must contain digits with distinct values modulo 3. (Sets with the same values mod 3 are [1,4,7], [2,5,8] and [3,6,9]).
• Digits separated by a white Kropki dot are consecutive.
• Digits separated by a black Kropki dot are in a 2:1 ratio.
