Sudoku is An Odd Serpent by Jeff Wajes, App variant is KILLER


Normal Sudoku rules apply. In cages, digits must sum to the small clue in the top left corner of the cage. An odd snake has made the grid its home! You must deduce the cells where the snake begins and ends. The snake has the following properties: the snake's body consists solely of odd digit cells; the snake visits all 9 boxes; the snake does not touch itself orthogonally (Diagonals are fine); the snake does not orthogonally touch any odd digit cell that is not part of its body (Diagonals are fine).
