Cascade

Battery-powered thing which launched ball-bearings onto 3 bouncy drums in succession and then onto a scoring receptacle at the other end. The ball would then (in theory) return to the electric elevator via a 3-foot plastic track .

Inevitably 'went wrong' eventually - The bounce went 'off' for some reason and you'd lose the ball under the sofa and give up in a huff. Unlike the gleeful moppets pictured on the lid. . . .
