Which is to say, not much substance to begin with. "The Deal" is in a different boat than "Millionaire." Millionaire at least has the questions, which used to come at a fast clip. You could fit in a couple of contestants on a show sometimes. "Deal or No Deal" has...picking numbers. If you were to make it viable as a syndicated show by removing four boxes and making the field $0.01 to $250,000; you still have people picking numbers. On the upside, there would be less time for the Relationship Bench antics and whatnot, but it's also a possibility that they would try to spread one contestant's game over two shows, changing nothing at all. With all of that, you have people picking numbers off of a board. "Treasure Hunt" somehow lasted for four years as a weekly product, and barely a year as a syndicated one, and it's the same game on an elementary level.
No syndicate would touch a show that has had payouts as high as "Deal" without some major changes. If it were my nickels, I would be pushing for an American version of the best game show on television anywhere in the world right now: "Temptation." But that's just me.
