Here is a slightly lengthened version of Toroidal Snake - etwas verküzt. The snake had found some food and got longer again.

Find a snake of unknown length. Head and the tail of the snake are already predetermined. The snake goes from cell to cell vertically or horizontally, but not diagonally. The snake does not touch itself, not even diagonally. The numbers outside the grid indicate how many squares are used by the snake in that row or column. Additionally in this variant the grid is a torus, i. e. the left and right border of the grid as well as the upper and bottom border are connected.
