At the Big Wheel, the bonus spin is far too often an anticlimax. We can all see it coming: the wheel goes zipping past $1.00, but clearly doesn't have the momentum to get all the way 'round again. Drew keeps trying to play it for suspense, but anyone who's ever been home from school sick knows the wheel isn't getting past 0.85. It comes off as disappointing, but it should be a celebratory moment; the contestant has just won a bunch of money and entry into the Showcase.
So...spinning $1.00 only gets you a bonus spin, no $1,000 cash bonus. But...whatever you land on in the bonus spin gets multiplied out to a bonus in thousands of dollars. Land on a quarter, you win $2,500. 80¢ means $8,000. $1.00 reverts to being worth $10,000, and the two green sections are back to $5,000 each. Minimum prize, therefore, is still $1,000 for hitting 10¢, but it builds to excitement and suspense instead of "Oh well, you didn't win anything more."
