Schaper King of the Hill - Vintage game review /demo

About King of the Hill, from BoardGameGeek:

Players take turns moving their marble to the top of the plastic mountain. If a marble lands on a hole, it is dropped in and comes out in a random fashion at a lower level cave. Marbles making it to the crown on top are dropped in, and will usually fall through to a lower level, but if the crown pops up, the player wins. Instead of a die, the game has a unique hourglass shaped teeter-totter piece which, when flipped, causes a small marble (keeping with the marble theme) to fall through a series of pegs to one of 6 slots at the bottom marked with numbers.
