Logic Masters Deutschland e.V.

The Sudoku Variant museum has reopened after extensive remodelling, and an Inquisitive Indexer Snake is the first to come and check out the new exhibits.
It enters the museum through one of the 4 exits (Corners) and wants to visit every exhibit (Box) exactly once, finishing at the centre of the museum (R5C5).

The snake consists of a single path of orthogonally connected cells that never touches itself orthogonally (diagonally is fine).
The Nth digit the snake passes through within a box gives the position of the digit N along its path within the box (e.g. if the 2nd digit the snake passes through in a box is a 5, then the 5th digit it passes through in the box must be a 2).

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

All standard variant rules apply.
