House Edge Explained: Every Casino Game Ranked (2026)
Picture this: you sit down at a roulette table with $200. Two hours later you walk away with $140. Bad luck? Not really — that's almost exactly what the math predicted. The casino's house edge took its share, one spin at a time, and you never even noticed.
Here's the thing most gamblers never learn: every casino game is mathematically designed to drain your bankroll at a specific rate. Blackjack with perfect play? The casino keeps about 50 cents per $100 wagered. American roulette? $5.26 per $100. Keno? Up to $25 per $100. The difference between these numbers is the difference between entertainment and financial ruin.
This guide breaks down the house edge for 40+ casino games, gives you five free calculators to run the numbers yourself, and shows you exactly how much each game costs per hour. Whether you're trying to pick the best game at the casino tonight or just want to understand why the house always wins, every number you need is right here — updated for 2026.
TL;DR — House Edge Quick Reference
Key Numbers at a Glance
| Game | House Edge | RTP | Loss per $100 | Bets/Hour | Loss/Hour ($10 bet) |
|---|---|---|---|---|---|
| Blackjack (1D, optimal) | 0.15% | 99.85% | $0.15 | 80 | $1.20 |
| Craps (Pass Line) | 1.41% | 98.59% | $1.41 | 60 | $8.46 |
| Baccarat (Banker) | 1.06% | 98.94% | $1.06 | 70 | $7.42 |
| European Roulette | 2.70% | 97.30% | $2.70 | 40 | $10.80 |
| American Roulette | 5.26% | 94.74% | $5.26 | 40 | $21.04 |
| Slots ($1, avg) | 4.00% | 96.00% | $4.00 | 600 | $240.00 |
| Slots (penny, avg) | 8.00% | 92.00% | $8.00 | 600 | $480.00 |
| Keno (4-spot) | 20.00% | 80.00% | $20.00 | 10 | $20.00 |
The sweet spot for most players: blackjack with basic strategy or baccarat banker — lowest edges, reasonable pace. Penny slots look cheap per bet but the speed kills your bankroll.
What Is House Edge? The Simple Explanation
House Edge in Plain English
House edge is the casino's built-in mathematical advantage on every bet. It's expressed as a percentage of your wager that the casino expects to keep over the long run.
Think of it like this: if you wagered $10,000 total on European roulette over an evening, the casino's 2.70% house edge means they expect to keep about $270 of that. You'd walk out with roughly $9,730 — on average.
The key phrase is "on average." In a single session, anything can happen. You might double your money or lose everything. But across millions of bets, the casino's take converges precisely to the house edge percentage. That's how casinos keep the lights on.
House Edge vs RTP: Two Sides of One Coin
You'll see both terms used interchangeably, but they measure opposite sides of the same thing:
| Metric | What It Measures | Formula | European Roulette |
|---|---|---|---|
| House Edge | Casino's take per bet | HE% | 2.70% |
| RTP | Player's return per bet | 100% − HE% | 97.30% |
House Edge + RTP = 100%. Always.
When a slot machine says "97% RTP," it means 3% house edge — the casino keeps $3 per $100 wagered. When a blackjack strategy guide says "0.50% house edge," it means 99.50% RTP.
A Real-World Example: European Roulette
European roulette has 37 pockets: numbers 1-36 plus a single zero. If you bet on red:
- 18 red numbers out of 37 total = 48.65% chance of winning
- You win 1:1 (bet $10, get $20 back)
- The math: 18/37 = 0.4865 (win) vs 19/37 = 0.5135 (lose)
- Expected return per $1 bet: (0.4865 × $1) − (0.5135 × $1) = −$0.027
- House edge: 2.70%
That single green zero is the casino's entire profit mechanism on this game. American roulette adds a second zero (00), creating 38 pockets and jumping the house edge to 5.26%. Triple zero roulette? 39 pockets, 7.69% edge. Same payouts, worse odds.

The House Edge Formula
Basic Formula: EV = P(win) x Payout - P(lose) x Bet
The house edge comes from the Expected Value (EV) formula. For any simple win/lose bet:
If EV is negative, the house has an edge. If positive, the player has an edge (rare outside of card counting and advantage play).
In plain English: multiply your chance of winning by what you'd win, then subtract your chance of losing multiplied by what you'd lose. The result tells you how much you expect to gain or lose per dollar bet.
Step-by-Step: European Roulette Example
Let's calculate the house edge for a straight-up bet on number 17 in European roulette:
- Win probability: 1/37 = 0.02703 (2.703%)
- Payout: 35:1 (you win $35 for every $1 bet)
- Lose probability: 36/37 = 0.97297 (97.297%)
- EV calculation: (0.02703 × $35) − (0.97297 × $1) = $0.94595 − $0.97297 = −$0.02702
- House edge: 2.70%
Notice it's the same 2.70% whether you bet red/black, odd/even, or a single number. Every bet on a European roulette wheel has the same house edge — the payouts are designed to ensure it.

House Edge for Every Casino Game (2026)
Here's the comprehensive ranking of 40+ casino games by house edge. This data comes from mathematical analysis assuming optimal strategy where applicable, cross-referenced with Wizard of Odds and Nevada Gaming Commission published statistics.
Table Games: Blackjack, Baccarat, Craps, Roulette
Table games generally offer the lowest house edges — if you know the optimal strategy. Here's the breakdown:
| Game | House Edge | Key Rule/Condition |
|---|---|---|
| Craps (Don't Pass + max odds) | 0.12% | Best combined edge in any casino |
| Blackjack (1D, optimal) | 0.15% | Requires perfect basic strategy |
| Blackjack (2D, optimal) | 0.35% | Double deck with good rules |
| Pontoon | 0.38% | Australian/British variant |
| Spanish 21 (optimal) | 0.40% | No 10s in deck, bonus payouts compensate |
| Blackjack (6D, optimal) | 0.50% | Standard shoe game, S17, DAS |
| Blackjack (8D, typical) | 0.66% | Common Vegas strip rules |
| Baccarat (Banker) | 1.06% | 5% commission on banker wins |
| Baccarat (Player) | 1.24% | No commission, slightly worse odds |
| French Roulette (La Partage) | 1.35% | Half bet returned on zero |
| Craps (Don't Pass) | 1.36% | Flat bet, no odds |
| Craps (Pass Line) | 1.41% | Most popular craps bet |
| Pai Gow Poker | 1.46% | Slow pace makes it cheap per hour |
| Craps (Place 6/8) | 1.52% | Good alternative to pass line |
| Ultimate Texas Hold'em | 2.19% | Requires optimal raise strategy |
| European Roulette | 2.70% | Single zero, all bets same edge |
| American Roulette | 5.26% | Double zero adds 2.56% vs European |
The takeaway: learn blackjack basic strategy and you're playing one of the best games in the casino. Don't know strategy? Baccarat banker is your best bet — no skill required, 1.06% edge.
Slots & Video Poker
| Game | House Edge | Notes |
|---|---|---|
| Video Poker (9/6 JoB) | 0.46% | Full-pay Jacks or Better, perfect play |
| Video Poker (Deuces Wild FP) | 0.76% | Full-pay, perfect strategy |
| Slots ($5, avg) | 3.00% | Higher denomination = better payback |
| Slots (online, avg) | 3.50% | Typically 96-97% RTP |
| Slots ($1, avg) | 4.00% | Mid-range denomination |
| Slots (penny, avg) | 8.00% | Worst common denomination |
| Progressive Slots (avg) | 10.00% | Jackpot contribution increases edge |
The counterintuitive truth about slots: denomination matters more than which machine you pick. A $5 slot machine returns about 97% while a penny slot returns only 92%. The difference costs you $500 per hour at 600 spins.
Specialty Games: Keno, Big Six, Scratch Cards
| Game | House Edge | Notes |
|---|---|---|
| Sic Bo (Big/Small) | 2.78% | Best sic bo bet |
| Casino War | 2.88% | Simple but mediocre edge |
| Red Dog | 3.50% | Rarely found |
| Let It Ride | 3.51% | Optimal strategy helps |
| Mississippi Stud | 4.91% | Strategy matters a lot |
| Caribbean Stud | 5.22% | Big progressive jackpot doesn't compensate |
| Triple Zero Roulette | 7.69% | Never play this variant |
| Big Six Wheel ($1) | 11.11% | Tourist trap |
| Sic Bo (Triple) | 13.89% | Sucker bet |
| Baccarat (Tie) | 14.36% | Worst common table bet |
| Craps (Any 7) | 16.67% | Worst craps bet |
| Keno (4-spot) | 20.00% | Terrible expected value |
| Big Six Wheel ($20) | 24.07% | Worst wheel bet |
| Keno (10-spot) | 25.00% | The house keeps a quarter |
| Lottery (typical) | 50.00% | Entertainment only |

Online vs Land-Based Casino House Edge
Why Online Casinos Often Have Lower Edge
Online casinos don't pay for massive buildings, thousands of employees, or free drinks. Those savings translate directly into better odds for players. Here's the comparison:
| Game | Land-Based Edge | Online Edge | Savings |
|---|---|---|---|
| Slots (penny) | 8-12% | 3-5% | 3-9% |
| Slots ($1) | 4-6% | 2.5-4% | 1.5-2% |
| Blackjack (6D) | 0.5-2% | 0.3-0.6% | 0.2-1.4% |
| Roulette | 2.7-5.26% | 1.35-2.7% | 1.35-2.56% |
| Video Poker | 0.5-5% | 0.2-1% | 0.3-4% |
Online roulette often offers European rules (2.70%) or even French La Partage (1.35%), while most US land-based casinos default to American roulette (5.26%). That alone saves you $10/hour.
RTP Regulations by Jurisdiction
Different jurisdictions set minimum RTP requirements:
| Jurisdiction | Min RTP (Slots) | Enforcement |
|---|---|---|
| UK (UKGC) | Published required | Strict, audited quarterly |
| Malta (MGA) | 92%+ | Regular testing |
| Nevada | 75% (actual ~92%) | Gaming commission oversight |
| New Jersey | 83%+ | Monthly reports published |
| Macau | 80%+ | Government monitored |
| Online (Curacao) | None mandated | Self-regulated |
How to Find a Casino's Actual RTP
- Online casinos: Check the game info/rules page — most publish the RTP
- Las Vegas: Nevada Gaming Commission publishes monthly slot payback by denomination and area
- Specific slots: Search "game name RTP" — most manufacturers publish this data
- Table games: The math is fixed by the rules. Learn the rules, you know the edge

How House Edge Destroys Your Bankroll
The Mathematics of Bankroll Erosion
House edge isn't something you feel on a single bet. It's a slow bleed — a mathematical grinding machine that takes a tiny piece of every wager. The problem is most players underestimate the cumulative effect.
Think about it this way: if you bet $10 per hand at blackjack (0.50% edge) playing 80 hands per hour, the casino expects to keep $4 per hour. Play for 4 hours? That's $16. Manageable.
Now switch to penny slots. Same $10 budget, but at 600 spins per hour with an 8% edge: the casino expects $480 per hour. That's 120x more expensive than blackjack for the same bet size.
Expected Loss Formula: Bet x HE x Rounds
The formula every casino player should know:
This is the single most important equation in gambling. Let's apply it:
| Player | Game | Bet | Bets/hr | Hours | Total Wagered | Expected Loss |
|---|---|---|---|---|---|---|
| Tourist | American Roulette | $10 | 40 | 2 | $800 | $42.08 |
| Regular | Blackjack (6D) | $25 | 80 | 4 | $8,000 | $40.00 |
| Slot Player | Penny Slots | $2.50 | 600 | 3 | $4,500 | $360.00 |
| Smart Player | Craps (Pass + 5x odds) | $10+$50 | 60 | 4 | $14,400 | $34.08 |
The smart craps player wagers far more total dollars but loses less because the free odds bet has zero house edge. That's the power of understanding the math.

Can You Beat the House Edge?
Blackjack Card Counting: The Math
Card counting is the most well-known advantage play technique, and it genuinely works — in the right conditions. The basic idea: track the ratio of high cards to low cards remaining in the shoe. When the deck is rich in 10s and Aces, the player has an edge.
A skilled Hi-Lo counter can gain a 0.5-1.5% edge over the casino, depending on rules, penetration, and bet spread. But it requires:
- Perfect basic strategy (non-negotiable)
- 200+ hours of practice counting
- A bankroll of 200-400x your max bet to survive variance
- Tolerance for getting backed off or banned
For a detailed breakdown, see our Spanish 21 card counting guide which covers modified counting systems.
Video Poker: Playing Perfect Strategy
Full-pay video poker machines (9/6 Jacks or Better, full-pay Deuces Wild) return over 99.5% with perfect strategy. Some machines even return 100.7% — a player advantage. The catch: these machines are increasingly rare, and "perfect strategy" means memorizing dozens of decision rules.
Sports Betting: Finding +EV Bets
Sports betting is fundamentally different from casino games. The "house edge" (vig) can be overcome by finding lines where the true probability exceeds the implied probability. Our no-vig calculator helps you strip out the bookmaker's margin.
Professional bettors maintain 2-5% ROI over thousands of bets. For more on whether you can make a living from sports betting, see our detailed analysis.
The Vig Explained
The vig (vigorish, juice) is the sportsbook's equivalent of house edge. Standard -110/-110 odds create a 4.55% total margin:
- True probability of a coin flip: 50%
- -110 implied probability: 52.38%
- The 2.38% gap on each side = the book's edge
Shopping across multiple sportsbooks using Wong teaser strategies and hedging calculators can reduce your effective vig significantly.
Poker: The One Game Where You Can Win
Poker is unique because you're playing against other players, not the house. The casino takes a rake (typically 5% of each pot, capped), but a skilled player can overcome this by winning more from weaker opponents.
The top 10% of poker players are consistent winners. The other 90% subsidize them — and the casino takes its cut either way.
Advantage Play Methods Ranked
| Method | Theoretical Edge | Difficulty | Risk of Ban |
|---|---|---|---|
| Blackjack counting | +0.5% to +1.5% | High | High |
| Video Poker (full-pay) | +0.2% to +0.7% | Medium | Low |
| Sports betting (+EV) | +1% to +5% | Very High | Medium |
| Poker (skilled play) | Varies by field | Very High | None |
| Labouchere / systems | 0% (no real edge) | Low | None |
| Slot bonuses (hunting) | +1% to +3% | Medium | Medium |
House Edge for Different Player Types
The Tourist ($50 Budget, 2 Hours)
You're in Vegas for the weekend and want some casino fun without blowing your dinner money. Best strategy:
| Game | Bet | Bets/hr | 2hr Expected Loss | Entertainment Value |
|---|---|---|---|---|
| Craps (Pass Line) | $5 | 60 | $8.46 | High — social, exciting |
| Blackjack (basic strategy) | $10 | 80 | $8.00 | High — skill involved |
| Baccarat (Banker) | $10 | 70 | $14.84 | Medium — simple |
| American Roulette | $5 | 40 | $21.04 | Medium — social |
| Penny Slots | $0.50 | 600 | $48.00 | Low — isolated |
Bottom line: For a $50 budget, blackjack and craps give you the most time at the table with the lowest expected loss. Penny slots will eat your budget in about 2 hours.
The Regular ($200/Session, Weekly)
You play every Saturday. Annual gambling spend matters. Here's your yearly expected loss at 4 hours per session, 50 weeks:
| Game | Bet | Weekly Loss | Annual Loss |
|---|---|---|---|
| Blackjack (basic strategy) | $25 | $40 | $2,000 |
| Craps (Pass + 3x odds) | $10+$30 | $34 | $1,700 |
| European Roulette | $10 | $43 | $2,160 |
| American Roulette | $10 | $84 | $4,210 |
| $1 Slots | $1 | $96 | $4,800 |
Switching from American to European roulette saves you $2,050 per year. Learning blackjack basic strategy saves even more.
The High Roller ($5,000+, VIP)
At high-stakes play, the house edge becomes real money fast. But high rollers get comps (free rooms, meals, flights) that offset some losses:
| Game | Bet | 4hr Expected Loss | Typical Comp Value | Net Cost |
|---|---|---|---|---|
| Baccarat (Banker) | $500 | $1,484 | $400-600 | $884-1,084 |
| Blackjack (optimal) | $500 | $800 | $300-500 | $300-500 |
| American Roulette | $500 | $4,208 | $800-1,200 | $3,008-3,408 |
Smart high rollers play baccarat or blackjack. The casino comp programs are based on theoretical loss (expected loss), and low house edge games get the best ratio of comps to actual losses.

Common House Edge Myths Debunked
"Hot" and "Cold" Machines
Slot machines don't have memory. Each spin is an independent event generated by a random number generator. A machine that just paid a jackpot has the exact same probability of hitting another jackpot on the very next spin. The concept of "hot" or "cold" streaks is pattern recognition applied to random data — a cognitive bias called the gambler's fallacy.
"The Casino Changes the RTP"
Land-based slot machines have their RTP set by an EPROM chip that's physically sealed and verified by gaming regulators. Changing it requires filing paperwork with the gaming commission, shutting down the machine, replacing the chip, and having it re-inspected. Casinos cannot flip a switch to tighten slots on weekends.
Online casinos have even less ability to manipulate individual RTP because the games run on third-party software audited by testing labs like eCOGRA, BMM, and GLI.
"Betting Systems Beat the House"
No betting system — Martingale, Fibonacci, Labouchere, D'Alembert, or Oscar's Grind — can change the house edge. Here's the proof:
Every system boils down to a sequence of bets, each with the same house edge. The total expected loss is the sum of (bet size × house edge) for every bet in the sequence. No matter how you arrange the bet sizes, the expected loss per dollar wagered stays constant.
Systems create the illusion of winning by producing many small wins and rare large losses (Martingale) or smooth-looking curves. But the expected value is identical to flat betting.
"I Can Win if I Play Long Enough"
The opposite is true. The longer you play, the more certain the house edge becomes. In 10 bets, anything can happen. In 10,000 bets, your results will cluster around the mathematical expectation with high probability. The Law of Large Numbers guarantees it.
If you're interested in how this affects your bankroll, try turning $100 into $1,000 at a casino — our analysis shows the real probabilities.
Responsible Gambling: Treating House Edge as Entertainment Cost
Setting Loss Limits Using Expected Value
The healthiest way to approach casino gambling is to treat the house edge as a known entertainment cost — like the price of admission to a theme park.
Before each session:
- Calculate your expected loss using the session calculator above
- Set that amount as your budget — bring only what you're comfortable losing
- Set a time limit — the longer you play, the closer results converge to the expected loss
- Never chase losses — the house edge doesn't change based on your current results
A $50 expected loss for 3 hours of entertainment is $16.67/hour. Compare that to a movie ($15/2hrs = $7.50/hr) or a concert ($100/3hrs = $33/hr). Casino entertainment is reasonably priced when you pick the right games.
Warning Signs: When the Edge Is Eating Too Much
- Gambling budget exceeds 5% of your monthly income
- Playing slot machines for hours when table games are available at the same spend
- Chasing losses by moving to higher-denomination machines
- Unable to walk away when reaching your loss limit

Methodology & Data Sources
How We Calculated These Numbers
All house edge values in this guide are derived from:
- Mathematical first principles — combinatorial analysis for table games, probability theory for roulette and craps
- Wizard of Odds — cross-referenced with Michael Shackleford's published calculations (the gold standard for casino math)
- Nevada Gaming Commission — published monthly slot statistics by denomination and region
- Published operator data — RTP figures from licensed online casino operators under UKGC and MGA jurisdictions
- Gaming lab certifications — BMM Testlabs, eCOGRA, and GLI published audits
Where "optimal strategy" is noted, the house edge assumes perfect basic strategy for blackjack, optimal hold/draw decisions for video poker, and mathematically correct side-bet decisions for poker variants. Real-world house edge is typically higher for most players due to strategy errors.
All data current as of March 2026. Slot RTP figures represent industry averages — individual machines vary.
