A Tentative Ten Snake wants to visit the Sudoku Variant museum, but is unsure about the crowds.
It enters the museum through one of the 4 exits (Corners), and wants to quickly visit every exhibit (Box) exactly once, then head out a different exit before it gets overwhelmed.

The snake consists of a single path of orthogonally connected cells that never touches itself orthogonally (diagonally is fine).
Within each box, the snake's path can be split into non-overlapping contiguous segments that sum to 10.

Solve the sudoku such that there exists a unique path for the snake through the museum.

All standard variant rules apply.
