The question hides a bet-by-bet answer
You walk onto a casino floor and ask which game pays out best. The honest answer is that no single game holds that title, because the payout structure changes from one bet to the next within the same game. A baccarat table offers a banker bet with a relatively low house edge and a tie bet with a much higher one. A craps table spreads dozens of bets across the felt, and the edge on a pass line wager looks nothing like the edge on a hardway bet. The game is the wrong unit of comparison. The bet is the right one.
What you are really looking for is the wager that takes the smallest mathematical slice out of each unit you risk. That slice is called the house edge, and it is built into the payout odds rather than added on top of them. When a casino pays less than the true odds of an event, the difference is the edge. The game does not need to cheat; the payout table already contains the advantage.
House edge and Return to Player are two ways of describing the same relationship under one rule set. RTP is a theoretical percentage of total wagered money a game returns to players over a very large number of spins or hands. House edge is the mathematical advantage the operator holds, expressed as a percentage of each wager. They sum to 100% for the same game. If a bet carries a house edge of 1 unit in every 100 wagered, its RTP is 99 units in every 100. Neither figure tells you what your next session will do.
How the edge is built into the payout
Every casino wager pays according to a schedule that slightly undercompensates the true probability of the event. On a European roulette wheel, there are 37 pockets and a single zero. A straight-up bet on one number pays 35 to 1. The true odds against hitting that number are 36 to 1, because there are 36 losing pockets and one winning pocket. The gap between 35 and 36 is the house edge on that bet. The wheel does not remember what just hit, and no betting pattern changes that arithmetic.
On an American wheel, the situation worsens. American wheels have 38 pockets with a double zero. The extra pocket increases the house edge on the American layout, because the payout for a straight-up number stays at 35 to 1 while the true odds shift to 37 to 1. The same bet on the same-looking game carries a materially different edge simply because of an extra pocket on the wheel.
Blackjack works differently. The objective is a hand total closer to 21 than the dealer's without exceeding it. The house edge there is not a fixed number printed on the felt; it emerges from the specific rule set in use. Deck count, dealer stand rules, doubling and splitting rules all shift the edge. Published basic-strategy charts derive from those rules, which means a chart built for one table may not fit the table next to it. The player's decisions genuinely change the expected rate of loss, which is rare among casino games.
| Game | Where the edge lives | What changes it |
|---|---|---|
| European roulette | 37 pockets, single zero, payout below true odds | Bet type; straight-up and outside bets carry different edges |
| American roulette | 38 pockets, double zero added | Extra pocket raises edge on every bet |
| Blackjack | Rule set, not a fixed table payout | Deck count, dealer stand rules, doubling and splitting options |
| Baccarat | Payout odds on banker, player and tie | Bet choice; tie bet carries the highest edge |
| Craps | Payout schedule per bet type | Pass line, come, place and proposition bets all differ sharply |
RTP and edge under one rule set
RTP and house edge are complements only when you hold the rule set constant. A slot machine with a published RTP of 96 units per 100 wagered has a house edge of 4 units per 100 under that exact configuration. Change the denomination, the bonus feature, or the progressive contribution, and the relationship shifts. Volatility does not change a game's RTP. A high-volatility slot pays rarely but in larger chunks; a low-volatility slot pays often but in smaller ones. Both can carry the same RTP, and neither RTP figure predicts your next hour.
Progressive jackpots complicate the picture. Fixed jackpots pay a set amount; progressive jackpots grow from a share of qualifying wagers and reset after a win. Progressive contributions are typically taken out of the game's return, and some progressives require a maximum-stake bet to qualify. That means the base game may return less than the headline RTP while the jackpot is building, because a portion of each wager is being diverted into the prize pool. The advertised RTP usually reflects the long-run return including jackpot contributions, not the return you experience on a session where the jackpot does not hit.
For table games, RTP is rarely published on the felt. Instead, the payout schedule lets you derive the edge yourself. A baccarat table takes totals modulo 10, and the banker, player and tie bets carry different house edges, with the tie bet the highest. The banker bet pays less than even money because the house takes a commission on winning banker wagers. That commission is the edge, and it is printed in the table rules. The player bet pays even money but carries a slightly higher edge than banker. The tie bet pays a large multiple but hits rarely enough that its edge dwarfs both.
Why short sessions look nothing like long-run averages
RTP and house edge describe behaviour over a very large number of spins or hands. Your session is not that. Over a few hundred hands of blackjack, the actual return can swing far above or far below the theoretical figure. Variance is the reason. Variance describes how payouts are distributed over time, and it operates independently of the edge. A game with a low house edge can still produce a brutal short-run loss because its variance is high. A game with a higher edge can produce a winning session because variance happened to run in your favour.
The number of decisions per hour magnifies both the edge and the variance. Suppose you play a game with a house edge of 1 unit per 100 wagered, and you wager 1 unit per decision. At 60 decisions per hour, your expected loss is 0.6 units per hour. At 600 decisions per hour on a fast table or a rapid slot, the expected loss becomes 6 units per hour. The edge did not change. The exposure did. Games that resolve quickly multiply the amount of money you put through the same edge, which is why two games with identical RTP can feel completely different in practice.
This is also why the best-payout question cannot be answered with a single game name. The bet with the lowest edge on the floor might be a specific blackjack wager under a specific rule set, but if you play it slowly and deliberately, your expected loss per hour could be lower than a fast slot with a better RTP. Conversely, a low-edge game played at high speed can cost more per hour than a higher-edge game played slowly. The payout percentage is only one input. Decision speed, bet size, and session length are the others.
What you can and cannot control
You control bet selection. On a craps table, the pass line and come bets carry materially different edges from the proposition bets in the centre of the layout. Choosing the lower-edge bets reduces your expected rate of loss. You control rule variants, within limits: a blackjack table that allows doubling after splitting and stands on soft 17 carries a different edge than one that does not, and the table rules are usually printed or displayed. You control game speed and decisions per hour by choosing slower games or playing fewer hands. You control session length and bankroll sizing as a method of limiting total exposure.
You do not control the edge itself. No betting pattern changes the built-in edge of a negative-expectation game. Progression systems, including doubling after losses, redistribute outcomes rather than remove the edge. They change the shape of the session: many small wins punctuated by occasional large losses, or the reverse. The expected loss over a large number of decisions remains the product of the edge and the total amount wagered. A progression does not alter that product; it only changes when the losses arrive.
Suppose you double your bet after every loss on a game with a house edge of 1 unit per 100 wagered. Most sessions end with a small win that recovers the previous losses plus one unit. A few sessions end with a long losing streak that wipes out the entire progression. The arithmetic of those two outcomes, weighted by their probabilities, produces the same expected loss as flat betting. The system feels safer because the wins are frequent and the disaster is rare, but the disaster is large enough to offset the frequent wins. That is variance, not an edge removal.
Where to find the numbers that apply to you
The specific RTP of a slot is usually available in the game's information panel or paytable, often behind a help or info button. The house edge of a table game is not printed as a single number, but the payout schedule and rule set are posted at the table or available from the dealer. For online play, the game rules page typically lists the RTP and the rule variants. For a specific operator, the terms page and the game provider's published documentation carry the figures. No single source covers every game in every venue, and the same game title can carry different RTP settings in different places.
When a figure is not posted, you can still compare bets by reading the payout schedule. The gap between the payout and the true odds is the edge, and that gap is visible on any table layout. A bet that pays 35 to 1 on a 37-pocket wheel carries a smaller gap than the same bet on a 38-pocket wheel. A baccarat tie bet that pays 8 to 1 carries a larger gap than the banker bet that pays even money minus commission. Reading the schedule tells you more than any list of game names ever will.
FAQ
Does a higher RTP always mean a better game for the player?
Not by itself. RTP describes the long-run return under one rule set, but variance, decision speed, and bet size determine how a session feels and what it costs per hour. A high-RTP game with high volatility can produce long losing stretches, while a lower-RTP game with low volatility can feel steadier. Compare RTP only within the same game type and rule set, and treat it as a long-run average, not a session forecast.
Which table game bet has the lowest house edge?
The answer depends on the rule set in front of you. Blackjack basic strategy under favourable rules can produce a very low edge, but the edge shifts with deck count, dealer stand rules, and doubling and splitting options. Baccarat's banker bet and craps pass line bet also carry relatively low edges compared with other bets on their tables. The posted rules and payout schedules are the only reliable source for the figure that applies where you are playing.
Can a betting system overcome the house edge?
No. Progression systems change the distribution of wins and losses across a session, but they do not change the expected loss per unit wagered. Doubling after losses produces many small wins and occasional large losses; the weighted average of those outcomes equals the same expected loss as flat betting. The edge is built into the payout schedule, and no sequence of bet sizes alters it.
