The number that decides everything
Originals RTP compared
Same game, same mechanic, four times the house edge depending on where you open it. Nobody puts this in a table, so here it is.
Return to player is the long run theoretical share of wagers a game pays back. 99% RTP means a 1% house edge. It is the price of playing, quoted as a percentage, and it varies more between operators than almost anyone realises.
The headline comparison
Roobet publishes 96% on Mines. Stake publishes 99% on the same game. Identical mechanic, identical maths structure, four times the cost per bet. On $50,000 of turnover that is $2,000 versus $500, for exactly the same experience.
By operator
| Casino | Originals RTP | Evidence | Detail |
|---|---|---|---|
| Stake | 99% | Operator states | Stake publishes 99% on Dice, Limbo, Plinko, Crash and Mines on its own game pages. A handful of newer titles carry a higher edge and are not covered by the 99% figure. |
| Roobet | 96% to 98.6% | Operator states | Roobet publishes 96% on Mines and 97% on Crash. Dice is reported at 98.6%. RTP is not published for seven other in-house titles. |
| Rainbet | ~99% | Not verified | Rainbet does not publish an RTP figure for its Originals. A 1% default house edge on Crash and Dice is widely reported, which implies roughly 99%, but the operator does not state it. |
| Duel | 100% | Operator states | Duel states 100% RTP on its Originals within a daily wager allowance of 50,000 dollars with a 1,000 dollar maximum bet. Past that allowance simple Originals move to a 0.1% house edge. Beef is stated at 99.2%. |
| Shuffle | 99% | Operator states | Shuffle publishes 99% on Crash, Dice and Plinko. RTP is not published for Mines, Limbo, Keno, Waifu Tower or Chicken. |
| Gamdom | 100% | Operator states | Gamdom states 100% RTP on the first 5,000 dollars wagered daily, delivered as an instant partial return on eligible wagers. Past that allowance the standard house edge applies. |
| 1WIN | Not published | Not verified | We could not find a published Originals RTP figure for 1WIN on the operator site or in any independent audit. |
| BC.Game | 98% | Not verified | Reported at 98% on BC Originals. This figure needs a citable source before it is treated as verified. Independent audit write ups have previously placed BC Originals nearer 99%. |
| Thrill | Not published | Not verified | Thrill markets boosted RTP on third party slots but publishes no RTP figure for its eleven in-house Originals. |
By game
Operator level figures hide variation. Roobet is a good example: 98.6% on Dice, 97% on Crash, 96% on Mines. A single operator number would tell you none of that.

What 100% RTP actually means
Two operators publish zero house edge on Originals, and both cap it.
| Operator | Allowance | Per bet cap | Past the allowance |
|---|---|---|---|
| Duel | $50,000 wagered daily | $1,000 | 0.1% edge on simple Originals |
| Gamdom | First $5,000 wagered daily | Not stated | Standard edge |
Inside those caps the expected loss on those specific wagers is genuinely zero. That is mathematically real and worth having.
It does not make you likely to win. A zero edge game is a fair coin flip, and fair coin flips ruin undercapitalised players routinely, because variance operates independently of expectation. The operator can afford it because the allowance does not cover slots, live tables or post allowance play, which is where it actually earns from you.
The transparency gap
Three operators in our ranking publish no Originals RTP at all, and two more publish it on some titles while withholding it on others.
- Roobet publishes Mines and Crash, withholds seven other in-house titles.
- Shuffle publishes Crash, Dice and Plinko, withholds Mines, Limbo, Keno, Waifu Tower and Chicken.
- Rainbet, Thrill and 1WIN publish nothing we could find.
That silence is itself information. An operator confident in its game maths has no reason to hide it, and the studios supplying third party slots publish RTP as standard. When a casino advertises boosted RTP on games it did not build and says nothing about the ones it did, the asymmetry is worth noticing.
What RTP does not tell you
- It is not a prediction. It is a long run average across enormous sample sizes. Your session will not resemble it.
- Higher RTP is not positive expectation. 99% is still negative. Only the capped zero edge allowances reach neutral, and only inside the cap.
- It says nothing about variance. Two games at identical RTP can have completely different risk profiles, and variance is what actually determines whether you survive to see the long run.
- Risk settings do not change it. On most Originals, adjusting risk or mine count changes the payout distribution while leaving the edge constant.
Third party slots are a different problem
Everything above concerns in-house games. Slots from studios like Pragmatic Play and Hacksaw are frequently shipped at more than one RTP configuration, and the operator picks which one it runs. The same title can be several percentage points worse at one casino than another with no visible difference. The RTP variant problem
Gambling carries a negative expected return. Over enough bets the house edge wins by design, and no ranking on this site changes that. If it has stopped being a choice, free confidential help exists: Peluuri in Finland, Stödlinjen in Sweden, BZgA in Germany, and GamCare internationally.

Common questions
Which crypto casino has the best Originals RTP?
On published figures, Duel and Gamdom offer zero house edge inside daily caps of $50,000 and $5,000 of turnover respectively. Outside those caps, Stake and Shuffle publish 99% on their core titles, which is the best uncapped rate we can verify. Roobet publishes 96% on Mines, which is the worst figure any operator in our set discloses.
Does 99% RTP mean I keep 99% of my money?
No. It means the game pays back 99% of everything wagered over an enormous sample. If you deposit $100 and play it through ten times, that is $1,000 of turnover and roughly $10 of expected loss, not $1.
Can casinos change RTP?
On in-house Originals, yes, and without notice. On third party slots, the operator chooses between the RTP configurations the studio supplies. Check the in-game info panel rather than trusting any table, including this one.
Why do some casinos not publish Originals RTP?
They do not say. What we can observe is that the operators publishing the best figures publish them prominently, and three operators in our ranking publish nothing at all.
