The Complete Guide to Casino House Edge: Every Game Ranked From Best to Worst Odds
Introduction: The One Number Every Casino Player Needs to Understand
There is one piece of information that separates informed casino players from everyone else.
It is not a secret system. It is not a betting pattern or a lucky ritual. It is a single percentage figure that every casino game carries — a number that tells you exactly how much mathematical advantage the house holds over you on every bet you place.
That number is the house edge.
The house edge is the mathematical advantage a casino holds over players on every bet, expressed as a percentage of each wager the casino expects to keep over time. Blackjack with basic strategy has one of the lowest house edges at 0.5%, while American roulette sits at 5.26% and some slot machines can reach 10% or higher. Understanding these numbers is the single most useful thing you can do before sitting down at any casino table or spinning any reel — it tells you exactly how much the math is working against you, and which games give you the best shot at walking away ahead.
Most casino players never look at this number. They choose games based on how fun they look, how big the jackpots appear, or which tables their friends are sitting at. Then they wonder why they consistently lose faster at some games than others.
This guide changes that. It covers every major casino game, every significant bet type within those games, and ranks them all from the lowest house edge — where your money lasts longest — to the highest, where the casino’s mathematical advantage is most aggressive.
By the end, you will understand not just which games are better value, but why — and how to use that knowledge to get more enjoyment from every session you play.
What Is the House Edge? The Mathematics Behind Every Casino Game
The house edge is the built-in profit margin that every casino game carries, representing the percentage of each bet that the casino expects to keep over thousands of hands, spins, or rolls. If a game has a 2% house edge, the casino keeps an average of $2 for every $100 wagered — not per session, but across the long run of all bets placed on that game.
This distinction — long run versus single session — is critically important.
The house edge does not predict what will happen in any individual session. A player can sit at a high house edge game and walk away significantly ahead on any given night. Another player can follow perfect strategy at a low house edge game and still lose. Short-term variance is enormous in casino gambling and can produce any outcome over the course of an evening.
What the house edge does predict is the expected outcome over time, across thousands of bets. The more you play, the more closely your actual results will converge on the mathematical expectation implied by the house edge. This is why casinos are never concerned about individual sessions — the mathematics always delivers in the long run.
Return to Player — RTP — is just the flip side of the house edge. A game with a 5% house edge has an RTP of 95%. To get into the long-term average, we are talking hundreds of thousands if not millions of rounds. However, over time, results will converge on this RTP number.
Every Casino Game Ranked by House Edge
The chart and table below rank every major casino game and bet type from the lowest house edge to the highest — from the games where the casino’s mathematical advantage is smallest to those where it is most pronounced.
Here is a visual overview of where every major game sits on the spectrum:
Here is the complete reference table with every major game, specific bet types, house edge, and a plain-English rating:
| Game | Specific Bet | House Edge | Rating |

| Blackjack | Basic strategy, liberal rules | 0.50% | Excellent |
| Baccarat | Banker bet | 1.06% | Excellent |
| Baccarat | Player bet | 1.24% | Excellent |
| French Roulette | La Partage even-money bets | 1.35% | Excellent |
| Craps | Don’t Pass / Don’t Come | 1.36% | Excellent |
| Craps | Pass Line / Come | 1.41% | Excellent |
| Craps | Place 6 or 8 | 1.52% | Good |
| European Roulette | Any even-money bet | 2.70% | Good |
| Pai Gow Poker | Standard play | 2.84% | Good |
| Red Dog | Six decks | 2.80% | Good |
| American Roulette | Any standard bet | 5.26% | High |
| Caribbean Stud Poker | Ante bet | 5.22% | High |
| Slots | Average online slot | 4%–8% | High |

| Baccarat | Tie bet | 14.36% | Very High |
| Craps | Any Seven | 16.67% | Very High |
| Craps | Any Craps | 11.11% | Very High |
| Keno | Standard game | 25%–29% | Avoid |
Blackjack: The Best Odds in the Casino When Played Correctly
Blackjack, baccarat, and craps consistently offer the lowest house edges in any casino making them the best choices for players who want to maximize their playing time and minimize expected losses. But the specific bet within each game matters as much as the game itself. Blackjack’s edge drops to 0.5% or lower when you follow basic strategy — a set of mathematically proven decisions for every possible hand combination.
Blackjack’s exceptionally low house edge comes with a critical condition — the player must use basic strategy consistently. Playing by intuition, copying other players, or using superstition-based decisions dramatically increases the house edge.
If you are playing video poker with only one coin in or splitting tens in blackjack your house edge is much worse than the one stated. A strategy chart or other way of playing your hand correctly is essential.
The table rules also matter enormously:
Blackjack House Edge by Rule Variation:
| Rule Condition | Impact on House Edge |
|---|---|
| Blackjack pays 3:2 (standard) | Baseline |
| Blackjack pays 6:5 | +1.39% |
| Dealer stands on soft 17 | Baseline |
| Dealer hits soft 17 | +0.20% |
| Double down on any two cards | Baseline |
| Double down restricted to 9-11 | +0.09% |
| Can split Aces and re-split | Baseline |
| Cannot re-split Aces | +0.08% |
| Late surrender available | -0.08% |
The most important rule to check before sitting down is the blackjack payout. A table paying 6:5 instead of 3:2 adds nearly 1.4% to the house edge — instantly erasing most of the advantage that basic strategy provides and making the game barely better than American roulette.
Baccarat: Simple to Play, Among the Best Odds Available
The Baccarat Banker bet has a house edge of 1.06%, the lowest of any standard casino bet. According to Wizard of Odds and other gambling math sources, the Banker hand wins approximately 45.86% of all hands, the Player wins 44.62%, and 9.52% of hands result in a tie. Excluding ties, the Banker wins about 50.68% of the time which is why this bet has the best mathematical edge for players. The house takes a 5% commission on Banker wins.
Baccarat occupies a unique position in the casino landscape — it offers near-blackjack odds with near-zero skill requirement. The player simply chooses Banker, Player, or Tie before each hand and the game plays itself automatically according to fixed drawing rules.
The Tie bet deserves specific mention — not as a recommendation, but as a warning. Overall baccarat offers one of the lowest house edges in the casino especially when compared to games like roulette or craps. Baccarat odds for Banker bets are better due to how the game’s drawing rules work.
Baccarat Bet Comparison:
| Bet | House Edge | Recommendation |
|---|---|---|
| Banker | 1.06% | Always the best bet |
| Player | 1.24% | Acceptable alternative |
| Tie | 14.36% | Avoid entirely |
| Pair side bets | 10%–11% | Avoid entirely |
The practical advice on baccarat is straightforward — bet Banker almost exclusively, accept the 5% commission on wins as the cost of accessing the best available odds, and never place the Tie bet regardless of how many consecutive non-Tie results have appeared.
Craps: Outstanding Odds Hidden Inside a Complex Table
Craps intimidates many casino players with its elaborate table layout and seemingly infinite betting options. Underneath that complexity lies one of the best mathematical bets in the casino — and one of the worst.
Craps is a classic dice table game with some of the best wagers in casinos. The best bets to place include the Pass Line and Don’t Pass bets.
For just one casino game, house edge is all over the place on the craps table. We have high house edge one roll bets like Any Seven or Any Craps that are 16.67% and 11.11% against you.
The unique gem of the craps table is the Odds bet — the Odds bet is the only wager in the casino with a 0% house edge. By layering odds behind your Pass Line bet, you dilute the total house advantage to nearly negligible levels.
Key Craps Bets Ranked:
| Bet | House Edge | Notes |
|---|---|---|
| Odds bet (behind Pass Line) | 0.00% | Only zero house edge bet in any casino |
| Don’t Pass / Don’t Come | 1.36% | Slightly better than Pass Line |
| Pass Line / Come | 1.41% | Standard fundamental bet |
| Place 6 or 8 | 1.52% | Decent supplementary bet |
| Place 5 or 9 | 4.00% | Acceptable but not ideal |
| Place 4 or 10 | 6.67% | Poor value |
| Any Craps | 11.11% | Avoid |
| Any Seven | 16.67% | Worst bet on the table |
| Hardways (4 or 10) | 11.11% | Avoid |
The strategy lesson from craps is simple — stick to Pass Line and Don’t Pass bets backed by maximum odds. Avoid the one-roll proposition bets entirely. The table’s complexity exists partly to distract players from the best mathematical choices toward the worst ones.
Roulette: One Zero or Two Makes All the Difference
Roulette presents one of the clearest case studies in how a single rule change dramatically affects a player’s expected outcome.
European roulette — with a single zero pocket — gives the house a 2.70% edge on every standard bet. American roulette — with both a zero and a double zero pocket — pushes that edge to 5.26%. The single rule of La Partage in French Roulette drops the house edge from 2.70% to a highly competitive 1.35%. If the ball lands on zero you only lose half of your even-money bet.
Roulette Versions Compared:
| Version | Zeros | House Edge | Notes |
|---|---|---|---|
| French Roulette + La Partage | Single zero | 1.35% | Best roulette available |
| French Roulette + En Prison | Single zero | 1.35% | Equivalent to La Partage |
| European Roulette | Single zero | 2.70% | Good choice |
| American Roulette | Double zero | 5.26% | Nearly double the edge |
| Five-Number Bet (American) | Double zero | 7.89% | Worst roulette bet |
The practical implication is unambiguous — always choose European over American roulette, and actively seek French roulette tables with La Partage when playing primarily even-money bets. Neither the roulette ball nor the dice have memories. Doubling after every loss such as in the Martingale strategy is just a guide to the poor house. If you see nine black numbers roll consecutively on the roulette wheel the odds are no different on the next spin.
Video Poker: The Highest Possible Return When Played Correctly
Video poker sits at the very top of the value rankings — offering a house edge as low as 0.46% on full-pay Jacks or Better games with optimal strategy applied.
Many slot machines have a house edge of 5% to 10% and some video poker games have a house edge of .5% to 1%.
The critical distinction between video poker and slots — despite their physical similarity as machine-based games — is that video poker is a skill game. The decisions a player makes when holding and discarding cards directly determine the expected return of every hand.
Most Popular Video Poker Variants:
| Game | House Edge (Optimal) | Pay Table Requirement |
|---|---|---|
| Jacks or Better (full pay) | 0.46% | 9/6 pay table |
| Deuces Wild (full pay) | 0.76% | Full-pay schedule |
| Double Bonus Poker | 0.76% | 10/7 pay table |
| Double Double Bonus | 1.89% | Full-pay schedule |
| Jacks or Better (short pay) | 2%–5% | 8/5 or 6/5 tables |
The pay table distinction is crucial. A full-pay Jacks or Better machine paying 9 coins for a full house and 6 for a flush per coin bet offers the 0.46% edge. The same game on an 8/5 pay table pushes the house edge above 2.7% — the equivalent of European roulette on what looks like the same machine.
Always verify the pay table before playing any video poker machine. The difference between 9/6 and 8/5 is worth more than any bonus or promotional offer attached to the game.
Slot Machines: Entertainment Value Over Mathematical Value
Slots are the most popular game in any casino — online or land-based — and among the most variable in terms of house edge.
Many slot machines have a house edge of 5% to 10%. Some people simply shrug at casino slot RTP because they think they cannot discover it. Maybe ten years ago that was true but now we can google an individual slot and if we do not get an exact RTP we can get a pretty narrow range.
Online slots publish their Return to Player percentages, which makes comparison straightforward. A slot with 96% RTP has a 4% house edge. A slot with 94% RTP has a 6% house edge. The difference compounds significantly over extended play.
Typical Slot RTP Ranges:
| Slot Category | Typical RTP Range | House Edge Range |
|---|---|---|
| Premium online slots (top providers) | 96%–98% | 2%–4% |
| Standard online slots | 94%–96% | 4%–6% |
| Land-based casino slots | 85%–95% | 5%–15% |
| Progressive jackpot slots | 88%–94% | 6%–12% |
| Low-quality or unverified slots | Under 90% | Above 10% |
Volatility adds another dimension beyond raw house edge. A 4% house edge slot with low volatility produces frequent small wins. A 4% house edge slot with high volatility produces rare large wins with long losing streaks between them. Neither is mathematically superior, but each suits different player preferences and bankroll sizes.
The strategic implication for slot players is to prioritise games with published RTPs above 95% from reputable certified software providers, and to choose volatility levels that match both bankroll size and personal entertainment preference.
The Specialty Games: Keno, Scratch Cards and Proposition Bets
Not all casino games are created equal, and some exist primarily as entertainment products with house edges that reflect their lottery-like nature rather than competition for value-conscious players.
Keno has a house edge of 25%–29% — the highest of any standard casino game.
Keno, scratch cards, and similar lottery-format games typically carry house edges in the 20%–30% range. This does not make them wrong to play — entertainment value is subjective and players who enjoy the format get something real from that enjoyment. But players should understand clearly that these games consume bankroll significantly faster than table games or even standard slots.
Specialty Games Summary:
| Game | House Edge | Context |
|---|---|---|
| Keno | 25%–29% | Entertainment product — very high edge |
| Scratch Cards | 15%–30% | Varies significantly by jurisdiction |
| Big Six Wheel | 11%–24% | Depends on which segment bet |
| Casino War | 2.88% | Surprisingly decent for a simple game |
| Let It Ride | 3.51% | Decent for a poker-format game |
How to Use House Edge Knowledge: A Practical Framework
Understanding house edge numbers is only valuable if that knowledge changes actual playing behaviour. Here is a practical framework for applying this information.
Step 1 — Choose the Right Game for Your Goals
If maximising playing time on a limited budget is the priority, baccarat and blackjack with basic strategy offer the best mathematical foundations. If chasing a potentially life-changing payout is the goal, high-volatility progressive slots are the appropriate vehicle — but enter with realistic expectations about the house edge involved.
Step 2 — Within Each Game, Choose the Best Bets
Craps players who stick exclusively to Pass Line and Odds bets face a dramatically different mathematical environment than those who place proposition bets across the table. Roulette players who choose European over American tables cut their expected losses nearly in half. The game choice matters, but the specific bets within each game matter equally.
Step 3 — Understand What Betting Systems Cannot Do
A gambling strategy that depends on changing your bet to more consistently book winners cannot change the house edge. Doubling after every loss such as in the Martingale strategy is just a guide to the poor house.
No betting system — Martingale, Fibonacci, D’Alembert, or any other — changes the mathematical house edge on any bet. They redistribute wins and losses across a session in different patterns, but the expected outcome over time remains unchanged. A system that appears to work in the short term is simply experiencing normal variance, not mathematical superiority.
Step 4 — Set Session Bankrolls Proportional to Casino House Edge
A 1% house edge game is five times more forgiving of a given bankroll than a 5% house edge game. A player with $200 for an evening session can expect that money to last dramatically longer at a baccarat table than at a keno terminal. Matching bankroll size to the house edge of the chosen game is one of the most practical forms of gambling management available.
House Edge vs RTP: Two Ways of Saying the Same Thing
These two terms appear throughout casino content and describe the same mathematical relationship from opposite directions.
House Edge = the percentage of each bet the casino expects to keep over time.
Return to Player (RTP) = the percentage of each bet the player expects to receive back over time.
They always add up to 100%.
| House Edge | RTP | Practical Meaning |
|---|---|---|
| 0.5% | 99.5% | Casino keeps $0.50 per $100 wagered |
| 1.06% | 98.94% | Casino keeps $1.06 per $100 wagered |
| 2.70% | 97.30% | Casino keeps $2.70 per $100 wagered |
| 5.26% | 94.74% | Casino keeps $5.26 per $100 wagered |
| 10% | 90% | Casino keeps $10.00 per $100 wagered |
| 27% | 73% | Casino keeps $27.00 per $100 wagered |
Neither term is more correct than the other — they communicate identical information. Slot machines and online casinos typically publish RTP because the number appears larger and more player-friendly. Table game literature typically references house edge because the smaller number communicates the casino’s narrow profit margin more clearly.
The Bottom Line: Play Smarter, Not Just More
The house edge is not a reason to avoid casino gambling. It is a tool for approaching it more intelligently.
Every casino game is designed to be entertaining. The house edge is simply the cost of that entertainment — the price paid for the thrill of uncertainty, the social experience of a casino floor, and the possibility — however mathematically unlikely — of a memorable win.
Understanding house edge means paying that price at the lowest available rate. It means knowing that baccarat and blackjack offer dramatically more playing time per dollar than keno. It means choosing European roulette without a second thought when both versions are available. It means reading a video poker pay table before sitting down rather than after losing.
None of this guarantees winning. The house always has an edge. But understanding that edge — and consistently choosing the games and bets where it is smallest — is the single most effective thing any casino player can do to get more value, more playing time, and more genuine enjoyment from every session.
Frequently Asked Questions / Casino House Edge
Q1: Which Casino Game Has the Lowest House Edge?
Video poker played with optimal strategy on a full-pay Jacks or Better machine offers the lowest house edge in any casino at approximately 0.46%. Blackjack with basic strategy follows closely at approximately 0.50% under favorable rules. Baccarat’s Banker bet at 1.06% is the third-lowest standard casino bet and requires no skill or strategy to access. Among roulette variants, French roulette with the La Partage rule applied to even-money bets offers a house edge of just 1.35% — lower than European roulette’s standard 2.70%.
Q2: Does Basic Strategy Really Make That Much Difference in Blackjack?
Yes — the difference is substantial and measurable. A blackjack player using no strategy typically faces a house edge of 2% to 4% depending on specific decisions made. A player using correct basic strategy reduces that edge to approximately 0.5% under standard rules. The difference between 0.5% and 3% represents six times the expected loss rate on identical bets over identical playing time. Basic strategy charts are freely available, legal to use at most casinos, and can be referenced openly at the table. The investment of learning basic strategy is the single highest-return action available to any blackjack player.
Q3: Why Is the Tie Bet in Baccarat Such Poor Value When Baccarat Overall Has Great Odds?
The Banker and Player bets in baccarat benefit from the game’s near-even win probabilities — the Banker wins approximately 50.68% of resolved hands, giving it a house edge of just 1.06%. The Tie bet, by contrast, pays 8:1 but occurs on only approximately 9.52% of hands. The true probability of a Tie at fair odds would justify a payout of roughly 9.5:1 — the casino’s 8:1 payout creates a substantial gap that produces a 14.36% house edge. The Tie bet is essentially a different, much worse game sitting alongside one of the best bets in the casino. Avoiding it entirely is the single most impactful decision a baccarat player can make.
Q4: Are Online Slot RTPs Accurate and Can I Trust Published Numbers?
Yes — at properly licensed and regulated online casinos whose games are independently certified by testing agencies such as eCOGRA, iTech Labs, or Gaming Laboratories International. These agencies verify that game outcomes are genuinely random and that actual long-term returns match the published RTP figures within acceptable statistical tolerances. The RTP published for a slot reflects the expected return across millions of spins — individual sessions will vary dramatically from the stated figure due to the high volatility of slot games. The published RTP is accurate as a long-run mathematical expectation, not as a prediction for any specific playing session.
Q5: Can Betting Systems Like the Martingale Beat the House Edge?
No betting system can change the mathematical house edge of any casino game. The Martingale system — doubling bets after each loss — and similar progressive betting strategies redistribute wins and losses within a session into different patterns, but the expected outcome over a large number of bets remains identical regardless of bet sizing strategy. The Martingale produces frequent small wins at the cost of occasional large losses when a losing streak exceeds the player’s bankroll or the table’s maximum bet limit. Over time the system produces the same expected loss as flat betting at the same game. No mathematical system can overcome a built-in house edge — any apparent success is the result of normal short-term variance rather than genuine strategic superiority.
