Drag Strip!

The object of this game is to shoot the marble to "drag" your cars across the finish line first.

You place the marble in front of a knob on a spring. You pull back the knob and when you let it go the marble flies up a slight incline on your track and then rolls back down on one of the four lanes on the other side of the track. The marble will push one of your plastic cars towards the finish line. Depending on how far you pull back on the spring determines how fast your marble will shoot as well as which lane it will land in. You grab your marble and send it up the track again. Both players play as fast as they can simultaneously to win.

Components are two black marbles and 8 plastic cars (4 each of two colors: yellow, green or blue, depending on the edition).
