Divide the grid along the boundary lines so that every cell belongs to a snake. A snake is a one-cell-wide path at least two cells long that does not touch itself, not even diagonally. Colored cells must be at one of the ends of a snake. Two snakes of the same length may not touch orthogonally.

Clued cells must be part of a snake with a length of exactly that number of cells. Same letters replace the same number, different letters replace different numbers.

Snakes may have any amount of any type of clue.
