What Is House Edge & RTP?
House edge is the casino’s statistical advantage over players over the long run. If a game has a 2% house edge, the casino expects to keep $2 for every $100 wagered.
Return to Player (RTP) is the flip side — how much players can expect to get back over time. A slot with 96% RTP returns $96 for every $100 wagered (in theory, over millions of spins).
Critical insight: House edge compounds over time. A 1% difference in edge can mean thousands of dollars in difference over a gambling session. Choosing the right games is the single most powerful thing a player can do.

House Edge Comparison by Game
| Game | House Edge | RTP | Skill Factor |
|---|---|---|---|
| Blackjack (basic strategy) | 0.5% | 99.5% | High |
| Baccarat (banker bet) | 1.06% | 98.94% | Low |
| Craps (pass line) | 1.41% | 98.59% | Low |
| Video Poker (Jacks or Better) | 0.46%–5% | 95%–99.54% | High |
| European Roulette | 2.70% | 97.30% | None |
| Pai Gow Poker | 2.84% | 97.16% | Medium |
| Caribbean Stud | 5.22% | 94.78% | Low |
| American Roulette | 5.26% | 94.74% | None |
| Slots (varies) | 2%–15% | 85%–98% | None |
| Keno | 25%–30% | 70%–75% | None |
| Wheel of Fortune | 15%–24% | 76%–85% | None |
Blackjack — The Player’s Best Bet
Blackjack offers the lowest house edge of any casino game — but only if you play with perfect basic strategy.
The Math
- House edge with basic strategy: 0.5%
- House edge with perfect basic strategy + counting: 0.1%–0.5% (player edge possible)
- House edge without strategy: 2%–4%
Basic Strategy Fundamentals
- Always split Aces and 8s — never split 5s or 10s
- Double down on 11 vs dealer 2–10 (not vs Ace)
- Stand on 17+ (hard or soft)
- Hit on 12–16 vs dealer 7+ (dealer bust frequency)
- Never take insurance — it has a 7.4% house edge
Rule Variations That Matter
| Rule | Effect on House Edge |
|---|---|
| 3:2 blackjack payout | Standard (0.5% edge) |
| 6:5 blackjack payout | +1.39% house edge (avoid!) |
| Dealer stands on soft 17 | -0.22% (better for player) |
| Dealer hits on soft 17 | +0.22% (worse for player) |
| Double after split allowed | -0.14% |
| Surrender allowed | -0.08% |
| 8 decks | Standard |
| 1–2 decks | -0.20% to -0.35% |
⚠️ Critical: Never play 6:5 blackjack. The difference between 3:2 and 6:5 is the single most important rule variation. At 6:5, blackjack pays $12 for every $10 bet instead of $15 — that extra $1.39 per $100 is pure profit for the casino.
Baccarat — Simple & Low House Edge
Baccarat has one of the lowest house edges and requires zero skill. It’s purely a game of chance with three possible bets.
House Edge by Bet
| Bet Type | House Edge | Commission |
|---|---|---|
| Banker | 1.06% | 5% commission on wins |
| Player | 1.24% | None |
| Tie | 14.36% | Varies (8:1 or 9:1) |
The banker bet is the best — despite the 5% commission, it wins slightly more often than it loses (45.86% vs 44.62%).
The tie bet is a sucker bet with a massive 14.36% house edge. Never bet the tie.
Strategy: Always bet banker. There’s no pattern to track — each hand is independent. In online casinos, check whether the baccarat variant offers commission-free banker bets (slightly different odds).
Roulette — European vs American
Roulette is the most iconic casino game, but the difference between European and American versions is staggering.
| Variant | Numbers | House Edge |
|---|---|---|
| European Roulette | 37 (0–36) | 2.70% |
| American Roulette | 38 (0, 00, 0–36) | 5.26% |
| French Roulette | 37 (with La Partage rule) | 1.35% |
Best Bets in Roulette
- Even money bets (red/black, odd/even, 1–18/19–36) — 48.65% win probability
- French Roulette with La Partage — Even money bets get half your stake back if 0 hits (effective house edge: 1.35%)
Pro Tips
- Always play European or French roulette — never American (5.26% edge is brutal)
- Outside bets (red/black, odd/even) offer the best odds for casual players
- Avoid inside bets (single numbers, splits) — same house edge but higher variance
- Online roulette often offers lower minimums and faster play — set time limits
Slots & RTP — What to Look For
Slots are the most popular casino game but have the widest variation in house edge. The key is choosing high RTP slots.
RTP Ranges
| Slot Type | Typical RTP | Examples |
|---|---|---|
| High RTP online slots | 97%–98% | Blood Suckers (98%), Mega Joker (98%) |
| Standard online slots | 95%–96.5% | Starburst (96.1%), Book of Dead (96.2%) |
| Land-based slots | 85%–92% | Varies by jurisdiction |
| Progressive jackpots | 88%–94% | Mega Moolah (88.1%), Hall of Gods (94%) |
How to Find High RTP Slots
- Check game info — Most online casinos display RTP in game rules
- Search for “high RTP slots” at your chosen casino
- Avoid slot games without posted RTP — They’re likely below 94%
- Use bonuses — Free spins and deposit matches reduce effective house edge
Read our Free Spins Guide for maximizing slot bonus value.
Volatility Explained
- Low volatility — Frequent small wins, longer playtime
- Medium volatility — Balanced win frequency and size
- High volatility — Rare big wins, bankroll swings
Which to choose? Low volatility for bonus wagering (more consistent), high volatility for chasing big wins.
Craps — Best Odds in the Casino
Craps offers some of the best odds in the casino — but many players don’t know which bets to make.
Best Bets in Craps
| Bet | House Edge | Recommendation |
|---|---|---|
| Pass Line | 1.41% | ✅ Best starting bet |
| Don’t Pass | 1.36% | ✅ Slightly better |
| Come Bet | 1.41% | ✅ Good |
| Don’t Come | 1.36% | ✅ Good |
| Free Odds (behind Pass) | 0% | ✅ Best bet in the casino |
| Place 6 or 8 | 1.52% | ✅ Good |
| Place 5 or 9 | 4.00% | ⚠️ Okay |
| Place 4 or 10 | 6.67% | ❌ Avoid |
| Field (double on 2 or 12) | 2.78% | ⚠️ Sometimes okay |
| Hardways | 2.78%–11.11% | ❌ Avoid |
| Any 7 | 16.67% | ❌ Sucker bet |
| Proposition bets | 5.56%–16.67% | ❌ Sucker bets |
The Free Odds bet is the only bet in any casino with a 0% house edge. After a pass line bet, you can take “odds” up to 3x–100x depending on the casino.
Recommended strategy: Pass line + maximum free odds + place 6 & 8. That’s it. Ignore the rest.
Video Poker — Skill & Math Combined
Video poker combines slot-like gameplay with blackjack-level strategy. With optimal play, some machines offer nearly 100% RTP.
Best Video Poker Variants
| Game | RTP (Perfect Play) | Key Strategy |
|---|---|---|
| Jacks or Better (9/6) | 99.54% | Hold high pairs, avoid low pairs |
| Deuces Wild (full pay) | 100.15% | Hold deuces, draw to open straights |
| Joker Poker (kings or better) | 100.05% | Hold wild jokers, natural pairs |
| Double Bonus (9/7/5) | 99.11% | Focus on four-of-a-kind bonuses |
The “Pay Table” — Read Before Playing
The pay table determines RTP. Look for:
- 9/6 Jacks or Better — Full house pays 9:1, flush pays 6:1 (99.54% RTP)
- 8/5 Jacks or Better — Full house 8:1, flush 5:1 (97.30% RTP)
- That 1.5% difference matters massively over time
Frequently Asked Questions
What casino game has the best odds?
Blackjack with basic strategy (0.5% house edge). Followed by baccarat banker bet (1.06%), craps pass line (1.41%), and European roulette (2.70%).
Is it possible to beat the house edge long-term?
Not consistently. Even with perfect play, the house has a mathematical edge on most games. Card counting in blackjack can shift the edge, but casinos counter it with countermeasures.
What’s the worst casino game?
Keno (25%–30% house edge), followed by American roulette (5.26%) and most progressive slot jackpots (12%+).
Do online casinos have better odds than land-based casinos?
Generally yes — online slots have higher RTP (95%–98%) compared to land-based (85%–92%). Online table games also offer lower minimums.
How do casino bonuses affect the house edge?
Bonuses can effectively reduce — and sometimes eliminate — the house edge. A 100% deposit match with 30x wagering on a 97% RTP slot creates a positive expected value scenario. Read our Casino Bonuses Guide for the math.
Should I always play max bet on slots?
Only if required for jackpot eligibility. Otherwise, bet what fits your bankroll. Read our Bankroll Management Guide for stake sizing.
Conclusion
The house edge is the single most important concept in casino gambling. The difference between playing blackjack at 0.5% edge versus slots at 10% edge is the difference between a sustainable hobby and a quick loss.
