Logic Masters Deutschland e.V.

A Thoughtful Thermo Snake wants to spend the afternoon contemplating the exhibits at the Sudoku Variant Museum. It enters the museum through one of the 4 exits (Corners) and wants to visit every exhibit (Box) exactly once, before leaving the museum by a different exit).
The snake consists of a single path of orthogonally connected cells that never touches itself orthogonally (diagonally is fine).
Within each box, the snake passes through at least 2 cells, and the digits along its path within the box increase in the direction of travel.

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

All standard variant rules apply.
