Casino War is the casino table version of the card game most of us played as kids. The rules are nearly identical – high card wins – but a single decision on tied hands shapes whether you play one of the simplest table games in the pit or hand the house a much bigger edge than you should. This guide covers the full rules, payouts, the maths behind the always-go-to-war strategy, where Canadian players can find the game, and the side bets to ignore.

What Is Casino War?
Casino War is a head-to-head card comparison game played with six standard 52-card decks. In each round, you and the dealer each get one card; the higher card wins even money. If both cards match, you face the only real decision in the game: surrender half your bet or “go to war” by doubling up for a second showdown.
A Brief Background
The game was trademarked in the 1990s by Bet Technology and rolled out to U.S. casinos as a low-stakes, easy-to-learn alternative to blackjack and baccarat. It has since spread to land-based casinos in Canada, the Caribbean, and parts of Europe, and shows up sporadically in online casino lobbies as both a digital RNG game and an occasional live-dealer table.
Casino War Rules
Casino War uses standard poker card rankings – Aces are always high, suits are irrelevant, and there are no jokers. Here is how a single round plays out.
The Setup
Six decks are shuffled together and placed in a shoe. You make an “ante” wager inside the betting circle. There is usually an optional Tie side bet you can place at the same time; we will get to why you should leave it alone.
The Initial Deal
The dealer gives you one card face up and takes one card face up. Compare ranks:
- Your card is higher – you win even money (1 to 1) on your ante.
- Dealer’s card is higher – you lose your ante.
- Same rank – you have a tie and must choose what to do next.
Tie: Surrender or Go to War
On a tie, you have two options:
- Surrender – forfeit half of your ante and end the hand.
- Go to war – place a second wager equal to your original ante.
How “Going to War” Works
If you go to war, the dealer burns three cards face down, deals you one card face up, then deals themselves one card face up. From there:
- Your war card is higher – you win even money on your raise. Your original ante pushes (returned, no win, no loss).
- Your war card ties again – this is the best result. You win even money on the raise, and most casinos pay a 1-to-1 bonus on the original ante as well.
- Dealer’s war card is higher – you lose both bets.
Payouts and the Tie Side Bet
Main Bet Payouts
Every winning bet on Casino War pays even money. There are no jackpots, no scaling pay tables, and no bonus multipliers on the main wager. The only “bonus” available comes from winning a tied war, where you collect on both stakes instead of just one.
The Tie Side Bet
Most tables offer a Tie side bet that pays 10 to 1 if your first card and the dealer’s first card match in rank. It looks tempting, but it has a house edge of roughly 18.65% with six decks – one of the worst odds you will find on a casino floor. Skip it.
House Edge and Strategy
Casino War is genuinely simple, which makes the strategy short. There are only three things to remember.
Always Go to War on Ties
This is the single most important rule. With six decks, surrendering on every tie gives the house an edge of about 3.7%. Going to war on every tie cuts the house edge to roughly 2.88% on the ante (or about 2.7% measured against total money risked). Surrendering throws away around a full percentage point of expected return on every hand – never do it.
Skip the Tie Side Bet
As covered above, the 10-to-1 tie bet carries an 18% plus house edge. It is a one-roll novelty wager, not a serious play.
Look for Bonus Tie Payouts
Some casinos pay 2 to 1 or even 3 to 1 on the ante when you win after going to war (instead of the standard 1 to 1 bonus). The 3 to 1 version drops the house edge to about 2.33%, which is the best Casino War game you can find. If you have a choice between two tables, this is what to look for on the felt.
Casino War for Canadian Players
Online Availability
Casino War is not as widely stocked online as blackjack or baccarat, but you will find RNG (computer-dealt) versions in the table-game sections of casinos that carry titles from Playtech, Microgaming, and a few smaller studios. It rotates in and out of lobbies, so check the table games filter on your preferred site rather than assuming it is always there. Live-dealer Casino War is rare; Evolution and the major live-game studios focus on blackjack, roulette, baccarat, and game shows.
Live Dealer and Land-Based
In Canadian land-based casinos, Casino War is most likely to appear at properties that target casual or first-time players, often near the entrance to the table-game pit. Tables come and go based on traffic, so call ahead if you want to be sure. Minimums tend to be among the lowest in the room, often $5 or $10.
Tips for Playing Casino War
- Treat it as entertainment – the house edge is reasonable but not beatable, and there is no skill ceiling beyond “always go to war.”
- Set a session bankroll – ties happen on roughly 7% of hands, and losing a doubled bet on the war stings. Bring a stake you can absorb a few of those swings on.
- Bet flat – progressive systems like Martingale do not change the math and will eat through your bankroll quickly when a cluster of dealer wins shows up.
- Use it as a break game – many players enjoy Casino War between longer sessions of blackjack or poker because it requires no concentration.
- Check the table rules – confirm whether the war-tie bonus is 1 to 1, 2 to 1, or 3 to 1 before sitting down.
Frequently Asked Questions
Is Casino War the same as the War card game kids play?
The mechanic is the same – high card wins – but Casino War is a single-round bet against the dealer with the option to “go to war” on a tie, while the kids’ version is a long game played until one player has all 52 cards. If you want the family rules, see our guide to the War card game.
What is the house edge in Casino War?
About 2.88% on the ante in a standard six-deck game when you always go to war on ties. Surrendering on every tie raises the house edge to roughly 3.7%.
Should I ever surrender on a tie?
No. Surrendering results in a loss of about 1 percentage point of expected return per hand compared to going to war. Always raise.
Is the Tie side bet ever worth it?
Not at the standard 10-to-1 payout. The house edge is over 18%, which is far worse than the main bet. Skip it unless you are placing a one-off novelty wager.
Can I count cards in Casino War?
Card counting in Casino War is technically possible because high cards favour the player and low cards favour the dealer, but the edge gained is tiny – well under 1% even with a perfect count, and the game uses six shuffled decks with frequent re-shuffles. It is not a practical advantage play.
Conclusion
Casino War is one of the easiest casino card games you will ever learn: bet, compare cards, win or lose, and either surrender or go to war on a tie. Treat the strategy as a single rule – always go to war – ignore the Tie side bet, and look for tables that pay 2 to 1 or 3 to 1 on the war-tie bonus. Played that way, it is a fair-priced, low-pressure game that fits nicely between rounds of something more demanding.
