Snake Sum Sudoku 4
Normal sudoku rules apply except that the regions are irregular.
Additionally, a snake has to be drawn into the grid. The head and tail of the snake are in the two cells with the grey circles. The snake may not touch itself orthogonally, but it can touch itself diagonally.
The clues outside the grid indicate the sum of the digits located on the snake in the corresponding row/column. Considering "Snake" and "non-snake" as two colors, the given digits show how many cells orthogonally connected to the given are of a different color to the color of the given cell itself. All such possible digits are shown. NOTE: Digits placed by the solver CANNOT be true or they would have been given
Givens can be on or off the snake.

Probably both, I purposely made this one easier. The next one though...

Either this one is easier, or I'm getting good at Snake Sums. A few of the sums were even left unused.
