After placing an initial bet, both player and dealer receive one card. If the value of
the player’s card is higher than the dealer’s, then the player receives a 1 to 1
payout (even money) on his/her wager. In the event of a tie, the player can either
fold (and lose the initial bet) or go to war, by raising his/her bet by an amount
equal to the initial bet. Both player and dealer receive three cards face-down and
one card face-up. The player wins if his/her face-up card equals or beats the
dealer’s face-up card. If the player wins, he/she receives a 1 to 1 payout (even
money) on his/her raise wager only, and the initial wager is a push. If the dealer’s
face-up card is higher than the player’s face-up card, the player loses both bets.
Casino War is played with 6 decks and no Jokers.

Simple Casino War system
The objective of course is to bet a little with the potential for a larger return.

It goes like so:

First, bet one unit. If you win add another, making the second bet a total of three
units.
If you win the second bet there are six units on the table. Remove four, making the
third bet two units.
If the third bet wins, add two more units for a total of six on the fourth bet.
If the fourth bet wins, you collect a total of 12 units, ten of pure profit.
So if you lose the first bet, you lose one unit. If you win the first bet but lose the
second, that’s two units you’ve lost. If you win the second bet but lose the third
bet, your profit is two units. If you win the first three bets but lose the fourth, you
break even. If you lose the second bet five out of six times, and then win four
consecutive bets once, you break even.

I recommend you in case of tie go to war always – the house edge under these
rules is 2.88% and less when you fold ties.
