How do I know when the drawing will happen?

This is an instant-win sweepstakes where winners are determined at random at the time of entry. Each entry is randomly allocated a “Game Piece” evidencing their entry. A pre-selected number of these randomly issued Game Pieces are “instant-winner” Game Pieces. Entrants who are randomly issued an instant winner Game Piece win the prize associated with that instant Winner Game Piece.
