Logic Masters Deutschland e.V.

Normal sudoku rules apply.

Additionally the solver must find a single snake of orthogonally connected cells which does not touch itself (even diagonally).

Adjacent digits on the snake are in a ratio of 1:2 or 1:3.

Each white dot connects a pair of consecutive digits, one of which is on the snake. All white dots that touch exactly one snake cell are given (elsewhere, a pair of adjacent cells containing exactly one snake cell must not contain consecutive digits).

Digits in grey cells are not on the snake but show the number of snake cells in the surrounding (up to) 8 cells.
