Radio Ball is the 2nd pinball game put out by Radio Shack/Tandy (the first was Pinball itself in 1980-early 1981). While you can't design your own pinball machines as you could with the earlier one, this one features from 1 to 4 players, and has gameplay in such a way that you can get 3 balls going at once, if you hit the bonus's and other things right. It also featured much better ball and flipper physics compared to the original.
