Well, I'll add one more to the list: The Magnificent Marble Machine!
I only got to see a few episodes of it on Cincinnati's WXIX-TV during the summer of 1975, but emcee Art James would tell the game's players that \"you have to earn your marbles\" before they would play the show's front-game -- which, in fact, had nothing at all to do with pinball!
Instead, the players had to guess words from crossword puzzle-type clues (similar to those that would be later used on NBC's Scrabble, and the first team to correctly guess five words from their corresponding clues got to play the show's giant pinball machine for all the prizes. (And, on the few episodes of that show I got to see, they only got two balls per game unless they managed to top the game's preset \"Goal Score\" that earned them the third \"Golden Money Ball!\"
Needless to say, I considered the show's end game a lot better than its main game -- although in retrospect, the show's giant pinball machine was horribly engineered, even incorporating a \"gobble hole\" that real-life pinball machines hadn't had for some 12 years up to that time.
