How To Play The Game Cascade Perpetual Motion Marble Family Game by Matchbox - Marble Bouncing!

About Cascade, from BoardGameGeek:

"The super-action thump-a-drum game that's fun for the whole family!" An Electric motor turns a long screw that lifts metal balls to the top of a tower. Beneath the tower are three rubber headed drums that the player positions to maximize scoring. Once the drums are placed, the player releases the balls from the tower. They land on the first drum, bounce up and over to the next drum, and then on to the third drum. Finally they land in a scoring tray that is slotted to show different point scores. Some slots have holes in the back that drain the balls down a track and back into the tower. When all the balls have come to rest the player adds up his score and the highest score wins.
