The highest payout casino games — an honest guide
The phrase “highest payout casino game” gets used in two different ways. Payout can mean the size of a single win — in which case progressive jackpot slots win easily, with prizes regularly hitting €1-10+ million. Payout rate means the percentage of total amount wagered that returns to players over many bets — in which case video poker and blackjack are at the top, with returns of 99%+ when played optimally.
These are different concepts. A €10 million jackpot is a possible single outcome at very low probability; a 99.5% RTP is a statistical average across millions of bets. If you want the chance at a life-changing payout, slots are your category. If you want the best statistical chance of walking away with a positive session, video poker and blackjack with proper strategy are your category.
This guide covers both definitions honestly, with real RTP figures rather than the inflated numbers some affiliate pages quote. One important note upfront: even the highest-RTP games have negative expected value long-term. A 99.5% RTP means you lose 0.5% on average — better than slots’ 4-8% loss rate, but still a loss rate. Winning sessions come from variance, not from RTP advantage.
The terms that matter
RTP (Return to Player)
RTP is the percentage of total amount wagered that returns to players over a very large number of bets. A 96% RTP slot returns €96 of every €100 wagered on average. Important nuance: RTP applies to total amount wagered, not deposits. If you deposit €100 and play through €1,000 of total bets (normal with winnings replayed), a 96% RTP produces €960 expected return — meaning €40 expected loss from your €100 deposit, not €4.
House Edge
The casino’s statistical advantage on each bet, expressed as a percentage. It’s the inverse of RTP: a 96% RTP game has a 4% house edge. House edge can vary by bet type within the same game — baccarat has 1.06% on banker bet but 14.36% on tie.
Payout (single win)
The size of the win you receive when you win a bet. Different from RTP. A straight-up roulette bet pays 35:1 per win but most spins lose. A blackjack hand pays 1:1 (or 3:2 on naturals) but wins more often.
Volatility
How often a game pays vs how large the payouts are. Low volatility = frequent small wins. High volatility = infrequent large wins. Volatility doesn’t change RTP — it changes the session experience.
The honest hierarchy by RTP
Here’s the actual ranking with verified figures.
1. Video poker — highest RTP of any casino game
| Variant | Optimal RTP | House edge |
| Full Pay Deuces Wild (NSUD paytable) | 100.76% | -0.76% (player edge) |
| Full Pay Jacks or Better (9/6) | 99.54% | 0.46% |
| Bonus Poker (8/5) | 99.17% | 0.83% |
| Common Jacks or Better (8/5) | 97.30% | 2.70% |
| Common Jacks or Better (7/5) | 96.15% | 3.85% |
Three things to know:
- Paytable matters more than the name. “Jacks or Better” with a 9/6 paytable has 99.54% RTP. With an 8/5 paytable, 97.30%. The variant name alone doesn’t tell you what RTP you’re getting.
- Optimal strategy is essential. Casual play drops the RTP by 1-4%. The 99%+ RTPs assume perfect strategy execution.
- Full-pay variants are rarer online than at physical casinos. Many online “Jacks or Better” games use 8/5 or worse paytables. Verify before playing.
2. Blackjack — strong RTP with broad availability
| Variant | RTP at optimal strategy | House edge |
| Single Deck Blackjack (S17, 3:2) | 99.85% | 0.15% |
| Blackjack Switch (optimal switching) | 99.83% | 0.17% |
| Vegas Strip Blackjack (4-deck, S17) | 99.65% | 0.35% |
| Atlantic City Blackjack (S17, late surrender) | 99.64% | 0.36% |
| Classic 6-deck (S17, late surrender) | 99.55% | 0.45% |
| Classic 6-deck (H17, no surrender) | 99.30% | 0.70% |
| 6:5 blackjack (any variant) | ~98.10% | 1.90% |
These RTPs require basic strategy at all times. Untrained play at the same tables produces 96-98% effective RTP. Avoid 6:5 blackjack tables entirely — the 1.4% additional house edge erases the gains from playing strategically. See our How to Win at Blackjack page for the full strategy guide.
3. Baccarat — clean math, no skill required
| Bet | RTP | House edge |
| Banker bet (5% commission) | 98.94% | 1.06% |
| Player bet | 98.76% | 1.24% |
| Tie bet (8:1 payout) | 85.64% | 14.36% |
Banker bet is the optimal play. Never bet on Tie — the 14.36% house edge makes it among the worst bets in any casino game.
4. Craps — best bets exceptional, worst bets catastrophic
| Bet | RTP | House edge |
| Pass line + 10x odds | 99.82% | 0.18% |
| Pass line + 3x odds | 99.53% | 0.47% |
| Pass line (no odds) | 98.59% | 1.41% |
| Place bet 6 or 8 | 98.48% | 1.52% |
| Field bet | 94.44% | 5.56% |
| Hard 4 or 10 | 88.89% | 11.11% |
| Any 7 | 83.33% | 16.67% |
Craps has the widest range of bet quality in any casino game — from 0.18% house edge to 16.67%. Pass line + maximum odds is the optimal strategy. Avoid proposition bets.
5. Roulette — variant matters most
| Variant | RTP | House edge |
| French Roulette w/ La Partage (even-money bets) | 98.65% | 1.35% |
| European Roulette | 97.30% | 2.70% |
| American Roulette | 94.74% | 5.26% |
| American five-bet (0-00-1-2-3) | 92.11% | 7.89% |
French roulette with La Partage cuts the house edge on even-money bets in half compared to European. American is nearly twice the house edge of European — no reason to play it when European is available. See our How to Win at Roulette page for the full discussion.
6. Slots — wide range, jackpot potential
| Slot category | Typical RTP range | House edge |
| Top high-RTP slots (Mega Joker, Blood Suckers) | 98-99% | 1-2% |
| Standard quality slots (Book of Dead, Starburst) | 96-97% | 3-4% |
| Average online slots | 94-96% | 4-6% |
| Vegas physical penny slots | 88-92% | 8-12% |
| Progressive jackpot slots | 88-95% | 5-12% |
Slot RTP varies enormously. The highest-RTP online slots approach 99%. Average slots run 94-96%. Progressive jackpot slots typically have lower RTP because the jackpot pool draws from regular play — trading higher single-event potential for lower expected return.
NetEnt’s Mega Joker (99%), NetEnt’s Blood Suckers (98%), and Microgaming’s 1429 Uncharted Seas (98.5%) are among the highest-RTP slots available online.
Other games worth noting
- Sic Bo: Big/Small bets give 2.78% house edge — similar to European roulette.
- Three Card Poker: 96.6-98% RTP with optimal play.
- Casino Hold’em: 97.84% RTP at optimal play.
- Pai Gow Poker: 97.15% RTP.
- Keno: 65-80% RTP — among the worst in any casino.
- Scratch cards: 70-90% RTP — also among the worst.
What “highest payout” means for you
The right game depends on what you actually want.
Best statistical chance of winning a session: Full-pay video poker with optimal strategy (99.5%+ RTP). Second choice: blackjack with basic strategy.
Chance at life-changing single wins: Progressive jackpot slots — Mega Moolah, Mega Fortune, Hall of Gods. Lower base RTP, uncapped upside.
Entertainment without learning strategy: Baccarat (banker bet) or European roulette. Strong RTP, no strategic depth.
Welcome bonus value: Slots — they contribute 100% to wagering. Table games contribute 10-20%, making bonus clearance dramatically slower.
Low variance for extended sessions: Outside bets on European roulette, baccarat banker bet, blackjack basic strategy at low stakes.
Learning a skill that pays back: Blackjack and video poker. Both reward strategic study with measurably better RTP.
Common misconceptions
A few recurring confusions worth correcting.
“A 98% RTP slot means I’ll get €98 back if I play €100.” No. RTP applies to total amount wagered (including replayed winnings), not deposit amount. €100 deposit with winnings replayed often results in €500-1,000 of total wagering before the bankroll depletes.
“Higher RTP means I’ll win more often.” No. RTP describes the long-run average return, not win frequency. Higher RTP just means losses are smaller on average across many spins.
“Hot machines pay more often.” No. Slot RNG is independent of play history. A slot that just paid out has the same probability of winning on the next spin as one that hasn’t paid in hours.
“Casinos can adjust RTP to make games pay less.” At reputable licensed operators, no. RTP is set by the game provider and audited. Casinos can sometimes choose between different RTP versions of the same game (e.g. 92%, 94%, 96% versions), but they can’t adjust within a version.
“Tie bet in baccarat is a smart hedge.” No. 14.36% house edge. Never take it.
How to find genuine high-payout games online
Practical guidance for any Irish-facing casino:
- Check the game info panel for RTP — every reputable slot displays RTP in the in-game info menu. If RTP isn’t displayed, walk away.
- Look for full-pay variants in video poker — specifically 9/6 Jacks or Better paytable, NSUD Deuces Wild.
- Verify blackjack table rules — S17 (dealer stands on soft 17), 3:2 blackjack payout (never 6:5), late surrender available, double after split allowed.
- Choose European or French roulette over American — when both are available, European has half the house edge of American.
- Always bet Banker in baccarat — Banker 1.06% beats Player 1.24%; Tie at 14.36% is terrible.
- Stick to pass line + odds in craps — avoid proposition bets, hardways, big number bets.
- Choose properly licensed operators — Malta Gaming Authority, UK Gambling Commission, Curacao Gaming Control Board, or the emerging Gambling Regulatory Authority of Ireland (GRAI) under the Gambling Regulation Act 2024.
Frequently Asked Questions
What’s the highest payout casino game?
Two answers depending on what “payout” means. For highest RTP (return rate over many bets), full-pay video poker leads at 99.5%+ at optimal strategy, followed by blackjack with basic strategy at good-rule tables (99.55-99.65%). For highest single-event payout potential, progressive jackpot slots like Mega Moolah have paid €5-25M+ on individual spins despite lower base RTP.
Which casino game has the best odds?
Full-pay video poker with optimal strategy at 99.5%+ RTP. Blackjack at good-rule tables with basic strategy is comparable at 99.55-99.65%. Both require strategy investment; casual play drops the effective RTP by 1-4%.
What’s the difference between RTP and payout percentage?
In practice they mean the same thing — the percentage of total amount wagered that returns to players over many bets. Most affiliate sites use the terms interchangeably.
Can I really win at high-RTP games?
Short-term yes, long-term no. Even at 99.5% RTP, you lose 0.5% on average across many bets. Variance produces winning sessions frequently; discipline to walk away during those wins is what produces net positive sessions. Across thousands of bets, the house edge is mathematically unavoidable.
Do online casinos pay more than physical casinos?
Generally yes. Online operators have lower overhead, so they typically offer slightly better RTPs (96-98% online vs 92-95% physical for slots; similar gap for table games).
Should I play progressive jackpot slots?
Depends on what you want. Progressive jackpots have lower base RTP (88-93%) than non-jackpot slots (94-97%) because the jackpot pool draws from regular play. The trade-off is the chance at €1-25M+ single-event wins. For expected return, skip progressives. For jackpot upside, progressives are the only option.
What’s the worst payout casino game?
Keno (65-80% RTP), scratch cards (70-90%), and bingo (typically 60-80%) are at the bottom. The American roulette five-bet has 92.11% RTP. The baccarat tie bet has 85.64% RTP.
Is video poker the same as poker?
Mechanically similar but strategically different. Video poker is you vs the machine — you’re dealt 5 cards, choose which to keep, replaced cards are dealt, final hand pays per the paytable. Traditional poker is you vs other players with betting rounds and bluffing. Video poker has higher RTP than traditional poker variants because the math is precise.
What’s the safest bet in any casino?
Pass line + maximum odds in craps. The pass line has 1.41% house edge; the odds bet has 0% house edge (pays at true probability). The combined bet at 10x odds has effective 0.18% house edge — closest thing to a fair bet in any casino game.
Do live dealer games have the same RTP as RNG games?
Yes. Live blackjack and live roulette use the same math as RNG versions — same payouts, same odds, same RTP. Live dealer games tend to have slightly higher minimum bets and slower pace, which affects total exposure but not RTP per hand.
