Normal Sudoku rules apply. Cages sum to the value given, with no repeated digits.

A snake occupies all the cages, clockwise from its head in the top left cage to the tail in the centre cage.
The snake is orthogonally connected and may touch itself diagonally but not orthogonally.
The snake has an even number of cells in each cage, but no two adjacent cages include the same number of snake cells. It is the shortest snake possible.
The snake is a German Whispers snake, consecutive digits differ by at least 5.

The correct solution will be determined unambiguously by placing all the cells of the snake.
