Methods and devices for multi-state card games with card replacement
Players in a multi-state card game, such as blackjack or baccarat, are presented with opportunities to exchange their cards for new cards when the card game is in one or more particular states. These opportunities may include offers to redeal the player's hand of cards or redeal the player's opponent's hand of cards. Additionally, when the player is dealt a new card to be added to the player's hand, the player may be offered options to discard the new card, replace the new card with another new card, or to redeal the player's hand and/or the opponent's hand. In this way, the player may be able to improve his or her position in the card game. At the same time, the game provider may charge the player for acceptance of these offers, thus improving the profit margin of the game provider.
