If you surrender, you lose half of your Ante bet and the game is over.
If you choose to go to war, which is the recommended casino war strategy, you click the Raise button. This is where online casino war gets really exciting. First, an additional wager, which is equal to the amount of your original ante bet, will be automatically placed on the virtual casino war table. Then, you and the dealer will each receive an additional card. If your additional card is higher than the dealer's, you win the war; if his is higher, you lose.
If the additional cards result in another tie, you'll win an Ante Bonus of 2 to 1 on your Ante bet.
