Logic Masters Deutschland e.V.

Normal Sudoku rules apply. The final grid will contain a 1-width python, which begins in the given 1. The python may not touch itself orthogonally or diagonally.

Numbers in each blue square show how many of its 8 surrounding squares are python. Blue squares cannot be python. All possible blue squares are given.

The final grid contains a ghost; an identical copy of the python (shape, digits, orientation).

Blue squares do not care about the ghost, only the original python. The ghost may not share any squares with the original python, and may not touch it orthogonally or diagonally.

I recorded a video of myself setting this sudoku, which you can watch here.
