How do I play Prize or Surprise.
You start by picking one of the cases, which will be saved until the end of the mini-game.
As you play, you will remove the other cases one by one and receive House of Fun Offers.
Your case can be traded for the House Offer and the game will end or you can keep playing to open your case.
Once there is only one case left, you can choose to open it or your initial case.
