Normal sudoku and variant rules apply.

Whisper: Adjacent digits on a green line must differ by at least 5. Palindrome: The sequence of digits on a grey line must read the same in both directions. Renban: A purple line contains a set of non-repeating consecutive digits in any order. Region Sum: The sum of digits on a blue line is the same within every 3x3 box it enters.

Additionally there are four non-overlapping snakes in the grid. Each snake begins in box 1 and ends in box 9 forming a non-branching path of orthogonally connected cells which never completely fills a 2x2 region or enters a grey square. A digit in a grey square must equal the number of snake cells in the surrounding 8 cells. Each given line is a snake segment (lines of the same type may or may not be part of the same snake and snakes may include any number of lines including zero). Each snake has a different constraint: Whisper, Palindrome, Renban and Region Sum.

Fantastic puzzle! A lot of interesting logic was required even after the snakes were mostly formed.

Beautiful idea executed very well. I'd rate this as a fairly difficult 4 stars. Although I may have just approached it inefficiently. Thank you!
