Casino war is a casino card game based on the game of War. The game is one of the most easily understood casino card games, and is one of the only card game where players can beat the dealer more than 50% of the time.
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, though the aces are the high card.
If the player goes to war, the dealer burns (discards) 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 all three bets (original wager, "going to war" bet, and a matching wager from the dealer). 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.
