Based on the game of War, Casino War allows you to bet that you will receive a higher valued card than the dealer. You can place an optional side bet that pays out 10:1 if the cards are a tie.
The player and dealer each receive one card. Cards are valued as in poker with aces being the highest. If your card is higher than the dealer then you will win and your ante will pay even money.
If both player and dealer card values are equal then the side bet, if placed, will pay 10:1. You can then surrender or raise (go to war).
If you surrender, you receive back half of your ante and the game is over. If you raise, the dealer burns off 3 cards and gives you and himself 1 more card. If your card is equal to or greater than the dealers then you win and your raise bet wins 2:1 and your ante bet is a push. If the dealer card is the highest value then your ante and raise bets lose.
