This puzzle is a bit of a sequel to the puzzle Slanted Summer Rooms.

Rules:

Normal Sudoku rules apply.

German Whispers: Adjacent digits on a green line must have a difference of at least 5.

Numbers placed on lines outside the grid are numbered rooms clues.

Numbered Rooms: Clues outside the grid indicate the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.

Note: In order for the solution check to work properly, all numbered room clues (i.e., digits on lines outside the grid) must be filled in.
