Casino War is a classic card game where you simply have to obtain a card with a higher face value than your opponent. It is a casino card game based on the children's game of War. The dealer gives each player one card face up. Then the dealer takes a card face up. If you beat the dealer, you win your bet. If the dealer beats you, you lose. The cards have the same rankings as in poker, with the ace being the highest card, followed by the king, queen, jack and other in the series.

If your card ties with the dealer's card, you can either go to war with the dealer by matching your original bet or you can surrender
by forfeiting half your original bet. If you go for a war with the dealer, the dealer will burn three cards and give you another card. Then he will burn three more cards and take one for himself. If your 2nd card is higher then dealers then you win the bet. If your 2nd card ties with the dealer then also you win. The rub here is the dealer doesn't pay off the second bet you risk to go to war, which is how the house gets its edge.
