Premise: Bonus Bonanza was the official state lottery game show of Massachusetts, running from 1995 to 1998. It was hosted by Brian Tracey and Dawn Hayes. The show was produced at WCVB-TV by Jonathan Goodson Productions, and all of its games and its theme were virtually identical to the Illinois state lottery game show "Illinois Instant Riches" (later "Illinois Luckiest").
Hypothesis: Bonus Bonanza was almost exactly the same as the Illinois' state lottery game show.
