What are sweepstakes markets?

Selected markets will have a sweepstakes toggle. These require sweepcash to participate and allow winners to withdraw any sweepcash won to real money.
As play money and sweepstakes markets are independent of each other, they may have different odds even though they share the same question and comments.
