==== RULES ====
Normal Sudoku rules apply
Cells with circles are gas particles. Gas particles travel in the indicated direction(s), of a distance equal to their digit value. If they encounter the border of the grid, they bounce on it. The digit of a gas particle must appear at the end of its travel path (see example picture).
Not all possible particles are given (no negative constraint).

But do the gas particles obey the law of reflection (can I assume elastic collisions)? Neat puzzle.

nice concept, bouncing off the edges makes it quite different from the other similar variants, it was a pleasure to test it
@filuta : Thanks a lot ! for testing it, and the nice comment :). I'll notify you if I ever make another one with these rules.
