Casino War Rules and Odds: Go to War vs. Surrender Explained

Casino War rules are about as simple as casino games get: you and the dealer each receive one card, and the higher card wins. There are no hands to build, no decisions about holding or drawing, and almost no strategy. Yet one choice matters a great deal, and many players get it wrong: what to do when your card ties the dealer's.

This guide covers the rules, the payouts, the house edge for each decision and the one side bet to avoid. If you are comparing table games before you play, our casino strategy hub has more detail on how to choose games with better odds.

Quick answer: In Casino War, you and the dealer each get one card and the higher card wins. On a tie, you can go to war, which has a house edge of about 2.88%, or surrender and lose half your bet, which has a higher edge of about 3.70%. Going to war is the better choice.

How Casino War Is Played

Casino War is usually dealt from six decks. Cards rank from two (low) to ace (high), and suits do not matter. You place an ante bet, then you and the dealer each receive one card face up. If your card is higher, you win even money on the ante. If the dealer's card is higher, you lose the ante.

If the cards tie, you have two choices: go to war or surrender. You may also have placed an optional tie bet before the deal. Because there is no skill in the main hand, the game is decided by the tie decision and by your choice of whether to place the side bet.

The basic flow:

• Place your ante bet (and optionally a tie bet).
• Receive one card; the dealer receives one card.
• Higher card wins the ante at 1 to 1.
• On a tie, choose to go to war or surrender.

Going to War vs. Surrender

When your card ties the dealer's, going to war means you place an additional bet equal to your ante. The dealer burns three cards, then both of you receive a new card. If your card beats or ties the dealer's, the typical rule is that you win the ante at even money and the raise is returned, though some tables pay both. If the dealer's card is higher, you lose both bets.

Surrendering means you give up half of your ante and the hand ends. It feels like the "safe" option, but the math says otherwise. Over the long run, going to war costs you about 2.88% of the ante per hand under the common rules, while surrendering costs about 3.70%. That difference is not large on one hand, but it adds up over hundreds of decisions.

Because a tie happens roughly 7.4% of the time with six decks, the choice arises about once every thirteen or fourteen hands. The rule is simple: always go to war.

The Tie Bet: Why You Should Skip It

The tie bet pays 10 to 1 when your card and the dealer's card are the same rank. That sounds generous, but a tie happens less than 8% of the time, and the true odds are closer to 12 to 1. The result is a house edge of about 18.65% in a six-deck game, which is one of the highest in the casino.

Many tables also pay a bonus when you win the tie bet and then go to war and win. Some versions pay 1 to 1 on the ante and 10 to 1 on the tie, depending on the casino. Even with bonuses, the tie bet does not offset the heavy house edge. If your goal is to preserve your bankroll, avoid it.

Compare it with other side bets. In blackjack, side bets such as Perfect Pairs and 21+3 also tend to carry higher edges than the main game. Our live dealer casinos guide shows where these tables appear online.

House Edge Summary

Here is a quick comparison of the most common choices in a six-deck Casino War game:

• Go to war on ties: about 2.88% house edge.
• Surrender on ties: about 3.70% house edge.
• Tie bet: about 18.65% house edge.

For context, basic strategy blackjack has an edge well under 1% in favorable rules. Baccarat banker is about 1.06%. Casino War is not the best table game, but with the right tie decision it is a reasonable choice for casual players who want fast, low-thinking action.

The number of decks matters a little. Fewer decks increase the chance that a tie occurs, which slightly raises the house edge for surrender, and changes the value of the tie bet. Always check the rules posted at the table, and avoid versions that pay less than even money on the war win.

Online and Live Dealer Versions

Online casinos offer Casino War in both software-based and live dealer formats. The software versions typically follow the same rules, and the house edge numbers apply when the rules match. In a live dealer game, the dealer deals real cards from a shoe, and you can often see the full flow of the hand.

Some jurisdictions and casinos offer the game only in limited form or not at all. Before depositing, check the casino's game list and review the rules. Our best online casinos list can help you compare libraries and licensing. If a bonus is involved, check the contribution rate for table games, which is often lower than slots. Details are in the best casino bonuses guide.

Bankroll Tips for Casino War

Even simple games drain a bankroll if you play too fast. Casino War rounds are quick, and a dealer can complete many hands per hour. Decide how much you are comfortable losing before you sit down and stick to it.

• Set a session limit and a time limit.
• Play flat bets; no betting system overcomes the house edge.
• Avoid the tie bet entirely.
• Always go to war on a tie.
• Take breaks to avoid chasing losses.

Betting progressions such as Martingale do not change the long-term odds and can lead to big losses when a losing streak hits the table limit. If gambling stops being fun, use self-exclusion or deposit limit tools and contact a support service.
