When the game begins, all of your cards will be displayed, and the numbers will be announced. However, once the game begins, your Coins will be lost, if you leave for any reason. If you want to change your wager, you are free to leave Bingo before the game begins and your Coins will not be lost. Your wager is placed on each of the cards, so a 1,000 Coin wager for three cards will be a total of 3,000 Coins for the game. Casino World Bingo allows you to play up to four cards at a time.
