Casino war is a casino card game based on the children's game
of War. The game is arguably one of the most easily understood casino card games, but it also has a relatively large house
edge compared to other games.
The game is normally played with six standard 52 card decks. The cards are ranked in the same way that cards in poker games
are ranked, except that aces are always high
One card is dealt to a dealer and to a a player. If the player's card is higher he wins the amount
equal to his bet, if the dealer's card is higher, the player loses his bet.
A tie occurs when the dealer and the player each have cards of the same rank. In a tie situation, the player has two options:
- The player can surrender, in which case the player loses half the bet.
- The player can go to war, in which case the player must place an additional wager the same size as the first wager
Going to war
If the player goes to war, the dealer burns three cards before dealing each of them an additional
card. If the player's card is ranked higher than or the same as the dealer's, then the player wins an amount equal to the
size of the original bet only. If the dealer's card is ranked higher than the player's, the player loses both the original
bet and the "going to war" bet.
The dealer and the player each have a 50% chance of winning, so this seems like an even money game. The house advantage,
however, comes from what happens in the case of a tie.
Some casinos offer a bonus payout in the event of a tie after going to war.
The house advantage increases with the number of decks in play and decreases in casinos who offer a bonus payout. The house
advantage for this game is usually over 2%.
Surrendering has a slightly higher advantage for the house, so a player should never surrender.
