But if you choose to go to war (which we highly recommend), you'll need to double your initial bet before proceeding. Surrendering means forfeiting half of your original bet without going through further rounds. However, if your card ranks lower than the dealer's card, don't worry just yet! You have two options: surrender or go to war. If your card has a higher rank than the dealer's card, congratulations! You win even money on your initial bet. Playing Casino War couldn't be simpler! To begin, place your bet on either 'Player' or 'Dealer.' Once bets are placed, both you and the dealer will receive one card face-up.
