A discussion about the early CBS episodes of The Joker's Wild led me to ask these questions:
1. When did the show switch from the "jokers & devils" bonus round to the "money & devils" one most of us are familiar with?
2. When did the show get rid of the Joker Jackpot (and presumably switch to the "car for 5 wins" rule)?
I do know that a lot of changes (changing the bonus round from "prizes on each reel" to "jokers & devils"; triples were $200 instead of $150; three jokers no longer automatically won the game, but required that a question be answered; Joker Jackpot was won with 3 wins instead of 4) happened at the start of the third week.
