If I know the contestant has a chance to win or lose $1 million on the puzzle they are about to attempt would make it way more exciting to me than just seeing confetti after it is over...
And really, it's all about you.
Actually, as the viewer, I suppose that's true to an extent. But I also don't want those contestants up there crapping themselves and freezing up as they suddenly discover they are solving a puzzle for ONE MILLION DAMN DOLLARS, nor am I interested in that way extended moment of schadenfreude if they should fail. (And I realize there are people reading this who *are* interested in that moment, they know who they are, and to them I say: go screw yourselves.) I further do not want the moment that is going to happen the majority of the time where we discover that the contestant is playing for the minimum amount and all of the air is let out of the tires before we even see the puzzle.
Nope. There are way too many things that can go wrong, whereas you neatly dodge all of that the way it works now. Maybe at the expense of a little drama once in every, what is it, 24, 36 shows or so where they hit the Big One on the wheel, be it worth $100K or ONE MILLION DAMN DOLLARS, but over the long haul I would rather surrender a little drama for better gameplay (and better television) overall.
