TJW was an interesting idea, but it shouldn't have been labeled as The Joker's Wild, considering people would remember the prior version from just four years before. I think, with a different title it would've worked, but to avoid being called a TJW rip-off, use a different way of selecting the questions and dollar amounts (something other than a slot machine). With a good nite's sleep, I'll post the idea I came up with later on. :-)
As for the bonus round, I think it could kinda work like the Dream House thing. Have the contestant randomly select how many spins they could get, and then play. As for TTD, they have the CBS bonus game up now, which the 1990 version was very similar to (sans the corny "Dragon Slayer," and the bad rapping).
