Battery-powered thing from Matchbox which launched ball-bearings onto three 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. . . .
