Casino War

Casino War is a straight-forward card game normally played with 6 standard decks of 52 cards, though there are a couple of casino softwares that are running their Casino War game with a single deck.

Play Structure

The player places a bet and the dealer deals out one card to the player and one to themselves. The cards are then compared, ignoring suit, and the party with the highest card is considered the winner. Where both the player and the dealer hold a card of the same rank the player is offered the option to either ‘Surrender’ or ‘Go to War’. If the player chooses to Surrender, half their bet is returned and the round is over. If the player chooses to Go to War they have to place an additional wager equal to their initial wager then the dealer will discard (Burn) 3 cards then deal a further card to both the player and themselves. The results are decided as before with the party with the highest card winning. In the event of a tie the player wins.


Where the dealer wins, the player loses their whole bet. Where the player wins their bet is paid out at 1 to 1. Where a tie occurs, if the dealer wins the player loses both bets and if the player wins the dealer will payout the initial bet at 1 to 1 while the additional bet is considered a push.

Some casinos offer a bonus payout for a second tie result.

Tie Bet

Most Casino War games offer an additional side bet called the ‘Tie’ bet. This is a wager on the result of the round of play being a tie. In the situation where this occurs the player is paid at 10 to 1.

Winning Strategies

Optimal Strategy

The optimal strategy for Casino War is very straightforward;  as the table above shows the player should always Go to War and should never take the Tie bet.


Despite the similarity to Blackjack in that offline Casino War is dealt from a multi-deck shoe and as such the composition of the remaining cards is dependent on the cards that have already been dealt (the game has a ‘memory’) the asymmetrical nature of Casino War prevents Card Counting being a viable method of gaining an edge over the main bet.

While it is possible to count the Tie bet, the complicated nature of the necessary count and the high penetration that’s required make this an opportunity that’s unlikely to either be encountered or be the best game available.

Next card information which could be gleaned through a variety of legal methods including edge sorting (if casino procedures allowed for this), naturally occurring defects in the cards or catching the bottom card after the shuffle and cutting it to a specific position could provide a significant advantage for the player.

Beyond the basic outline above the best source of information on how best to play with additional information can be found in James Grosjean’s ‘Exhibit CAA: Beyond Counting’. This book is widely considered the Bible for the professional player and as such is not a worthwhile investment for anyone other than a full time professional Advantage Player (not to mention it requires a professional reference to obtain).


There are several methods of legitimately gaining an advantage over the online Casino War games. By and large these involve the use of promotions, bonuses from minimum deposit casinos and comp point systems as the games by themselves – assuming the game is functioning in a correct fashion – will not provide any additional information about the cards and shuffle after every hand.

It should be noted that online advantage play is not specific to Casino War and in recent years the wagering requirements for player’s choosing to play any table game has inflated to the point that Casino War is now often a sub-optimal choice for the player.
