Setup for Level 4 is generally the same as for Level 3. However, return 2 ghosts to the game box – in Level 4 you’ll only have 13 ghosts available.
Additionally, you will need to score more points with each pile. Place Rufus on space 20 of the scoring track (you’ll need to score 20 points by the end of the fist pile). Place Ronja on space 10 of the scoring track (you’ll need to score 60 points by the end of the second pile). Place the goal tile on space 20 of the scoring track too, to show that you’ll need to score 120 points total. Otherwise, there aren’t any rules changes for this Level.
