How about "Dotto", the 1958 game show starring Jack Narz, where contestants connected dots, and got to draw more connecting lines as they could answer questions, until they could figure out what it was they were drawing?
This was the show that triggered the quiz show scandals of the late 1950s, as a contestant saw a cheat-sheet (or something) for another contestant offstage.
Then the domino effect.....
[BTW I know that 1 episode of Dotto exists in its entirety, and I'd love to view it.....but have not been able to, yet. I don't live near NYC or El Lay.]
