Cascade by Matchbox®
I was perusing a website about 70's and 80's games when I saw an old Christmas present that I received which was really good for about 2 weeks and then never seen again. It was a game called 'cascade'. I remeber thinking it was a load of rubbish when I first opened it but once set up the ball bearings bounced along the three rubber drums perfectly landing in the scoring bay and would be raised up to the top again by an archimedes screw type affair. A bit Heath Robinson but amazing to watch.
