What happens at the end of "The Most Dangerous Game"?

At the end of "The Most Dangerous Game", Rainsford wins the game.  Although the hunt was the initial challenge, when the two men come face to face in Zaroff's bedroom, he issues another challenge to Rainsford.  This time, the winner gets to Zaroff's comfy bed, while the loser will be fed to Zaroff's hungry dogs.  At the very end of the story, Rainsford is obviously sleeping in Zaroff's bed.
