Normal sudoku rules apply. Furthermore:

- Digits on a line lie strictly between the digits on its endpoints. If part of a line is thickened, the digits on that part form a nondecreasing sequence in the direction of the arrow (e.g: 2, 3, 4, ... or 2, 2, 5, ...);

- Normal skyscraper rules apply. Clues outside the grid are skyscraper clues, i.e. every digit n represents a skyscraper of height n. Taller skyscrapers block shorter ones behind them from view. The numbers outside the grid denote the number of buildings seen from that direction in the row/column.

Hint:

Try to think about which side of the between line must be the upper bound, and which side must be the lower bound.
