Winning "Wheel of Fortune's" million-dollar prize is the no-hitter of game shows — a near impossible feat, a long slog made even less possible by the lineup in front of you, not to mention the luck of the spin. Last night Autumn Erhard pretty much walked the bases loaded then struck out the side in the bottom of the ninth. 
To win the prize, a contestant must land on a tiny ONE MILLION sliver of the wheel during the normal game against two other contestants — then obviously choose a letter on the board and solve the puzzle, like for any other prize during the early rounds. That puts the potentially million-dollar "envelope" into play ... but not until later.
Then that contestant has to win the episode and make it to the bonus round — without landing on bankrupt in between. That still doesn't mean you have a shot at the $1,000,000. 
Then you have to spin another, smaller wheel in overtime, hoping that after you solve the final clue, you'll have landed on the biggest prize of them all again. Erhard got that far on Thursday night's episode, until she got to the dreaded "Thing" category ... and picked some really bad letters.
