    • A Bingo card trade feature is disclosed. This feature can offer players the option to trade one set of Bingo cards for another set of different Bingo cards. This exchange can cost nothing or an additional preset cost. These trades can be established through the entity hosting the game. The traded cards can be available for further trades for the same Bingo game based on the business rule set by the entity. The players can be able to trade cards up until a specified time before the start of the actual game. The players can also be able to trade a card as many times as they wish depending on their budget. In one specific example, a “Bonanza Trade” can offer the player the ability to take a daubed Bonanza card that was purchased, add a dollar and get two new Bonanza cards in exchange.
