During the closing credits of the episode that exists, the logo for the show is underlined with the words Orange Series, like so.
What would that mean? Method of identification for different weeks of episodes, perhaps? I'm very curious.
I remember that as well, and somehow remember that the home game came with different sets of cards with different back colors: blue, orange, green, and so forth. Could it be that the "series" identified the sets of cards used on that episode?
