House edge and RTP: one number, two names
The house edge is the share of each bet a game keeps on average; the return to player (RTP) is the rest. A 99% RTP is a 1% edge, and the two always add to 100%. Both are averages over a very large number of bets. They describe what a game costs per dollar wagered, and they say nothing about a single session.
What makes the figure usable is that casinos publish it. Stake's house-edge guide tells players where: "Find the game's RTP or house edge in its information panel (marked as "i") or the paytable on Stake.com" (guide dated 15 October 2026). This page collects the figures the casinos we review state for their in-house games, with the date each was read, and sets the arithmetic beside them where a published paytable or formula allows it to be checked. Third-party slots and live tables are priced by their studios and are not covered here.
The ranking: lowest edge first
The reference column is Stake, the largest casino we review by deposit volume, which shows an RTP badge on each Original's game page. Each row gives the game, the figure Stake publishes for it, where it is published, and what the figure depends on.
| Game | Stated at Stake | Published where | What the figure assumes |
|---|---|---|---|
| Blackjack | 99.43% RTP, 0.57% house edge | Game-page RTP badge and house-edge guide (1 Nov 2026) | Best play on every hand under Stake's rules: unlimited decks, dealer stands on soft 17, blackjack pays 3:2 |
| Video Poker | 99.00% RTP | Game-page RTP badge (1 Nov 2026) | Best hold on every deal; the published paytable returns 98.94% by arithmetic |
| Baccarat (Banker) | 1.06% on Banker; 98.90% RTP overall | Game page (1 Nov 2026) | Banker bet after the 5% commission; Player is 1.24% and Tie 14.36% |
| Dice | 99.00% RTP, 1% house edge | Game-page RTP badge and house-edge guide (1 Nov 2026) | Nothing: the same at every win chance |
| Crash | 99.00% RTP | Game-page RTP badge (1 Nov 2026); 1% in the published formula | Nothing: the same at every cash-out target |
| Limbo | 99.00% RTP | Game-page RTP badge (1 Nov 2026) | Nothing: the same at every target multiplier |
| Wheel | 99% RTP, "house edge of just 1%" | Game page (1 Nov 2026) | Risk level and segment count change variance only |
| Mines | 99.00% RTP | Game-page RTP badge (1 Nov 2026) | Nothing: 0.99 times the fair multiplier at every step |
| Plinko | 99.00% RTP, 1% house edge | Game page (1 Nov 2026) | The 36 payout tables return 98.906% to 99.160% by arithmetic |
| Roulette (European) | 97.30% RTP, 2.70% house edge | Game-page RTP badge and house-edge guide (1 Nov 2026) | Nothing: 36/37 on every bet. A double-zero wheel costs 5.26% |
| Keno | 99.00% RTP, 1.00% house edge | Game page (1 Nov 2026) | The 40 payout tables return 98.65% to 99.07% by arithmetic |
Stake game pages, fairness documentation and house-edge guide, 1 Nov 2026. Arithmetic figures are ours, from the paytables Stake's games used on that date; see the game pages linked below for the working.
The rows are in the order this page ranks the game types, and on Stake's own figures that order is not strictly ascending. Baccarat's Banker bet, at 1.06%, costs slightly more than the 1.00% Originals listed under it. Keno, last in the list, is stated at 1.00%, well below roulette's 2.70%. And the 0.46% often quoted for video poker belongs to the classic full-pay table, which Stake does not use: its table is stated at 1.00% and returns 98.94% with perfect play. Read the figure in each row, not its position.
Only two rows involve skill. Blackjack's 0.57% and video poker's 1% are the price for a player who makes the best decision every time, and each mistake adds to it. Every other row is a fixed price: no choice of win chance, mine count, risk level or number changes what the game keeps per dollar wagered.
The same games at other casinos: stated figures
Stake's prices are not the industry's. The table sets out what eleven of the casinos reviewed here state for the same seven games. A figure in quotation marks is the operator's wording; a dash means the documents cited for that casino give no figure or it has no such game.
| Casino | Dice | Crash | Mines | Plinko | Keno | Roulette | Blackjack |
|---|---|---|---|---|---|---|---|
| Stake | 99.00% | 99.00% | 99.00% | 99.00% | 99.00% | 97.30% | 99.43% |
| Shuffle | 1.00% edge | 99% | 99% | "Around 1%" edge | — | 97.30% | "99.48% RTP with correct play" |
| Roobet | 99% | None stated | 96% | "99% RTP game" | 1% edge | None stated | None stated |
| Gamdom | 99% after a daily allowance | 99% after a daily allowance | 99% after a daily allowance | 99% after a daily allowance | "Around 99%" | 99% after a daily allowance | 0.57% edge after a daily allowance |
| BC.Game | 98 | 99 | 98 | 98 | 98 | 97.3 | — |
| Duel | 99.9 | 99.9 | 99.9 | 99.9 | 99.9 | 100 (Castle Roulette) | 99.9 |
| Rainbet | 99.00% | — | 96.00% | 99.00% | 99.00% | 97.30% | 99.60% |
| BetFury | 99.02% | 99.02% | 99.02% | 99.02% | 99.02% | 97.30% | 99.51% |
| BitStarz | 98% | 96% | 97.50% | 98% | 97% | 97.3% | 99.5% |
| 500 Casino | 1% edge | 6% of rounds end at 1x | 1% edge | About 4% edge | 2% edge | About 6.66% edge | 99.48% |
| Cloudbet | 99% | — | — | 99% | 99% | 97.30% European | — |
Stake: game-page RTP badges (1 Nov 2026). Shuffle: game pages (12 and 13 Nov 2026; Blackjack 1 Nov 2026). Roobet: game pages (1 Nov 2026). Gamdom: game pages (1 Nov 2026) and help centre (13 Nov 2026); the allowance is the first $5,000 wagered on its Originals each day, described as running at 100%. BC.Game: RTP field in its game data (13 Nov 2026), Classic Dice in the Dice column. Duel: the site's own table of game returns (1 Nov 2026), before the rakeback that Duel advertises as bringing Originals to 100% inside a daily allowance. Rainbet: "Max RTP" on each game page (1 Nov 2026). BetFury: RTP printed on the game tiles (11 Nov 2026). BitStarz: Originals game pages (11 Nov 2026). 500 Casino: help centre house-edge article (November 2026). Cloudbet: provably fair explainers (11 and 13 Nov 2026).
Read across any column and the spread is wider than the gap between game types. Mines is stated at 99% by Stake and Shuffle, 97.50% by BitStarz and 96% by Roobet and Rainbet: the same game at one, two and a half, and four times the cost. Crash runs from 99% at Stake to 96% at BitStarz, with 500 Casino ending 6% of rounds at 1x. Dice is the most uniform row, and BC.Game and BitStarz still price it at 98%. The first thing to check about a low-edge game is which casino's version it is.
Three of the lowest figures in the table come with conditions. Duel's Originals carry a 0.1% base edge, which an instant rakeback refunds inside a daily Zero Edge allowance; outside the allowance the base edge applies (see our Duel review; Duel is a commercial partner of this site). Gamdom's 100% applies to the first $5,000 wagered on its Originals each day, after which its games run at the figures shown. Rainbet labels its figures "Max RTP", the best case across a game's modes.
Where the stated figure and the arithmetic part ways
A stated RTP is a claim; a published paytable or formula is something that can be worked through. Where both exist they usually agree. The cases below are the ones on our game pages where they do not agree exactly.
| Game | Stated | By arithmetic | Working |
|---|---|---|---|
| Stake Video Poker | 99.00% | 98.94% | Best hold on each of the 2,598,960 possible deals under Stake's paytable (video poker page) |
| Stake Keno | 99.00% | 98.65% to 99.07% | Each of the 40 paytables against the hit odds for 10 of 40 (keno odds page) |
| Stake and Shuffle Plinko | 99.00%; "around 1%" edge | 98.906% to 99.160% | Each payout table against the binomial slot odds (Stake Plinko page) |
| Roobet Crash | None stated | 95.52% at a 2x cash-out | Roobet's published crash formula, in which 1 round in 25 ends at 1.00x (Roobet Crash page) |
| Gamdom Crash | 99% after the daily allowance | 98.00% at 2x; 97.21% at 10x | Gamdom's published sample code (Gamdom Crash page) |
| BC.Game Originals | 98 in the game data; "only 1%" edge in the game help articles; "from 99% to 96%" in a help-centre notice | 97.99% on Classic Dice; 97.97% to 98.10% on Plinko | The game's own payout rule and tables (BC.Game Dice and Plinko pages) |
| Cloudbet American Roulette | "97% RTP" | 94.74% | The payouts listed in the same explainer, 35:1 on a single number, on 38 pockets |
| Roobet Roulette | None stated | 93.33% | 2x on 7 of 15 tiles (Roobet Roulette page) |
Arithmetic is ours and is set out on the pages linked. BC.Game notice: help centre (article dated 26 Nov 2025). Cloudbet: provably fair Roulette explainer (13 Nov 2026).
Most of these gaps are small. Stake's keno and plinko tables land within 0.35 of a percentage point of the badge, and its video poker within 0.06. The larger ones are the cases where no figure is stated at all, or where one operator's documents give three different numbers for the same games. For BC.Game the figure that matches the game is the 98 in its game data, which is also what its info panel showed on 1 Nov 2026.
A low edge still loses: the arithmetic
A lower edge makes the game cheaper. It does not make it winnable over time. The table prices four edges two ways: the expected cost of $1,000 of wagers, and the chance of being ahead after a run of even-money (2x) bets of equal size.
| House edge | Example | Expected cost per $1,000 wagered | Ahead after 1,000 bets | Ahead after 10,000 bets | Ahead after 100,000 bets |
|---|---|---|---|---|---|
| 0.1% | Duel Dice at 2x, before rakeback | $1 | 47.5% | 45.6% | 37.5% |
| 1% | Stake Dice at 2x | $10 | 36.4% | 15.6% | 0.08% |
| 2% | BC.Game or BitStarz Dice at 2x | $20 | 25.3% | 2.2% | under 0.01% |
| 2.70% | Red or black on a single-zero wheel | $27 | 18.8% | 0.33% | under 0.01% |
Arithmetic: exact binomial probability of more wins than losses at a win chance of 49.95%, 49.5%, 49% and 48.65%. A level result counts as not ahead.
At a 1% edge, a little over a third of players are ahead after 1,000 even-money bets, about one in six after 10,000, and fewer than one in a thousand after 100,000. At 2.70% the same journey is over within 10,000 bets. Volume is what converts a small edge into a certain loss, which is why auto-betting matters more than the choice between two 99% games: 10,000 bets of $1 at 1% cost $100 on average however quickly they are placed.
Rakeback narrows the figure without reversing it. Stake's help centre puts its rakeback at 3.5% of the house edge, which on a 1% game returns 0.035% of turnover; BetFury pays 10% of the edge. A rebate that is a fraction of the edge leaves the rest of the edge in place. Our rakeback calculator and house edge calculator turn any of these figures into a cost per session, and the responsible gambling page covers limits.
Game by game: why each edge is what it is
Blackjack
Blackjack is the only common game where the stated edge falls below 1% without a rebate, and it does so only for a player who makes the best choice on every hand. Stake states 99.43% for its Original under published rules (unlimited decks, dealer stands on soft 17, 3:2, one split). BetFury prints 99.51%, BitStarz 99.5%, 500 Casino 99.48% and Rainbet a "Max RTP" of 99.60%; the rules behind those four figures are not set out beside them. Insurance is a separate bet priced at 7.69% on an unlimited-deck game. The working is on our Stake Blackjack page and the decisions are in the blackjack strategy guide.
Dice, Crash, Limbo, Mines, Plinko, Wheel
These games are priced by formula. The casino works out the fair multiplier for the bet and pays a fixed fraction of it: 0.99 at Stake, so the edge is 1% at every setting. That is why no win chance, target, mine count or risk level is better value than another within one casino's game. The fraction itself differs between casinos, as the table above shows, and for Plinko and Wheel it is built into payout tables that can be checked one by one. Mechanics and worked examples: Dice, Crash, Limbo, Mines, Plinko, Wheel. Not every Stake Original is a 1% game: Stake states 98% for Dragon Tower, Slide and Pump and 98.29% for Diamonds (Dragon Tower page).
Baccarat
Baccarat's prices come from the drawing rules and the 5% commission on Banker wins. Stake states 1.06% on Banker, 1.24% on Player and 14.36% on Tie, the standard eight-deck figures, and 98.90% for the game overall; 500 Casino states the same three. Rainbet gives a "Max RTP" of 98.96%. There are no decisions after the bet, so the only choice that matters is avoiding the Tie.
Roulette
A single-zero wheel pays as if it had 36 pockets and has 37, so every bet returns 36/37. Stake, Shuffle, Rainbet, BetFury and BitStarz all state 97.30% for their in-house European wheels. Games that share the name can be priced very differently: Gamdom's 101-number colour wheel returns 99.01% on red or black and Roobet's 15-tile wheel 93.33%. Betting systems do not change any of these figures; the arithmetic is in our roulette strategy guide, and the three in-house games are compared on the Stake Roulette and Roobet Roulette pages.
Keno
Keno is priced by its paytable. Stake states 99.00% and its tables return 98.65% to 99.07% depending on picks and risk level; BC.Game's game data says 98 and BitStarz states 97%. The hit odds, the full grid of returns and the stated figures of fifteen casinos are on the keno odds page.
How to check a figure yourself
Two different things can be checked, and they answer different questions. The first is the price. Where a casino publishes a formula or a paytable, the return is arithmetic: multiply each payout by its chance and add them up. The stated figure is in the game's information panel; the tables are in the game.
The second is the individual result. On a provably fair game the outcome is computed from a server seed whose hash is shown before the bet, a client seed you can set and a counter. After you rotate the seed pair the server seed is revealed, and anyone can recompute the result and confirm it was fixed in advance. Our provably fair verifier does this for the casinos whose methods are published in full, with game-specific tools for Dice, Crash, Limbo, Mines, Plinko and Keno; the background is in what provably fair means.
A verified result proves the game was not altered for that bet. It does not tell you the edge, and a fair game can be an expensive one. You need both numbers.
Where to play the low-edge games
By stated figures, the cheapest in-house games among the casinos reviewed here are Duel's Originals (0.1% base edge, refunded inside a daily allowance), Gamdom's Originals inside its daily allowance, and blackjack at any casino that states 99.4% or more, for a player who follows correct strategy. Among the games with no conditions attached, the 1% Originals at Stake and Shuffle and the 0.98% originals at BetFury are the lowest fixed prices in the table.
Roobet and Gamdom price game by game: Roobet states 99% for Dice and 96% for Mines, and its crash formula returns about 95.5%. An edge is one input among several. Licence, withdrawal terms and identity checks are covered in each review, the full field is on best crypto casinos, and the casinos with published verification schemes are on the provably fair casinos list.
Key takeaways
- The lowest stated edge at Stake is Blackjack at 0.57%, for correct play only. Its Dice, Crash, Limbo, Mines, Plinko, Wheel and Keno are stated at 1%.
- The same game is priced differently by casino. Mines is stated at 99% by Stake and 96% by Roobet and Rainbet.
- Stated figures and paytables do not always match exactly. Stake Video Poker is stated at 99.00% and returns 98.94% with perfect play.
- Single-zero roulette costs 2.70% on every bet, and games that borrow the name range from 0.99% to 6.67%.
- A low edge still loses. At 1%, fewer than one player in a thousand is ahead after 100,000 even-money bets.
