1) Double Dare
2) Supermarket Sweep
3) Debt
Double Dare is one of the absolute pitch perfect blends of trivia, strategy, stunts, and competition games ever put to tape, and one of the best balances of humor/seriousness/sincerity.
Supermarket Sweep is phenomenal and losing my huge gigantic pile of eps from the Buzzr reruns in a cloud storage issue was a crushing disappointment
I wholly and sincerely think Debt is Wink Martindale's best show and plays to every single one of his strengths as an emcee. The trivia is solid (and moving away from the J! style board in season 2 was, IMO, actually a good change), and I think the double or nothingish (they still got a savings bond) stage 2 of the bonus game is the single best implementation of that mechanic in the genre canon, while the preceding trivia countdown has all the suspense of Alphabetics or the Winner's Circle bonuses. If Lifetime hadn't lost interest in doing game shows, this show absolutely should have gotten a longer run.
