Spook alarm! Call the ghost hunters! Restless spirits are everywhere in Geisterfalle and only the players can stop them. Each player has a ball track and three ghost-trapping balls in front of them; these balls must be rolled into the holes of the ball track to capture the ghosts. Whoever does so first yells "Stop!", which ends the round. Players score points, then begin a new round, and in the end whoever scores the most points wins.
