I too will go with the Big Money Game from $otC as well as the Big Money Winners Board, All you're really doing is matching prizes Concentration-style. There was one good upside to all of that. Once you cleared the board, you have one more chance to risk everything you won on the board for a shot at a $50K grand prize jackpot. Winning the last game gets your prizes back + the cash jackpot. Losing that game meant forefieting your bonus prizes(but NOT your Instant Bargains, Fame Game & Instan Cash prizes along the way).
Also, the NBC version of HS had a bonus round that was strictly luck-based at one point. It's where each celebrity had an envelope with the description of a prize on it. I'd rather have Peter Marshall ask one more question for the chance to win that prize instead of haphazardly finding the prize instantly like that.
