Normal sudoku rules apply. There is an orange snake in the grid, which moves from one cell center to the next horizontally or vertically (i.e., never diagonally). It may not touch itself orthogonally. The snake divides the non-snake cells into 8 different regions, one of each size from 1-8 cells. Each of these regions is orthogonally contiguous and acts like a killer cage. Each cage encloses exactly one sum clue, which indicates the sum of the digits in that cage, and digits may not repeat in any cage. (The sum clue need not be in the top left corner of the cage). The snake itself is a so-called 'Dutch Whisper' line, i.e. neighboring digits on the snake must differ by 4 or more. The white dot joins consecutive digits.
