Casino RTP Database
Not all casinos run the same slot at the same RTP. Providers like Pragmatic Play offer operators multiple RTP tiers — the casino chooses which one to deploy. We track which platforms offer the highest payouts.

Understanding RTP in Online Slots
RTP (Return to Player) is the theoretical percentage of wagered money a slot returns to players over time. A slot with 96.50% RTP will, on average, return $96.50 for every $100 wagered. The remaining 3.50% is the house edge — the casino's profit margin on that game.
The critical insight many players miss: the same slot can have different RTPs at different casinos. Most slot providers offer operators multiple RTP configurations. For example, Pragmatic Play's Gates of Olympus has a default RTP of 96.50%, but can be set to 95.50%, 94.50%, or even lower. The casino chooses the tier — and a lower RTP means more profit for the operator at your expense.
This page tracks RTP configurations across our ranked crypto casinos, so you can make informed decisions about where to play. For a deeper dive into the mathematics, read our complete RTP guide.
How the RTP Tier System Works
Provider RTP Tiers — Example
Most providers offer 3-5 RTP tiers to operators. Here is a typical Pragmatic Play slot:
The difference between Tier 1 and Tier 4 is 9.5 percentage points — meaning the casino keeps 3.5x more of your wagers at the lowest tier.
Real Impact on Your Bankroll
To understand the financial impact, consider wagering $10,000 total on a slot:
The lowest RTP tier costs you almost 4x more than the highest. This is why knowing your casino's RTP configuration matters.
Popular Slots — RTP by Platform
Below are observed RTP values for popular slots across our ranked crypto casinos. Values are based on the in-game RTP display and provider documentation. Where casinos do not disclose RTP in-game, we note it as "undisclosed."
| Slot | Provider | Default RTP | Stake | BC.Game | Cloudbet |
|---|---|---|---|---|---|
| Gates of Olympus | Pragmatic Play | 96.50% | 96.50% | 96.50% | 96.50% |
| Sweet Bonanza | Pragmatic Play | 96.48% | 96.48% | 96.48% | 96.48% |
| Wanted Dead or a Wild | Hacksaw Gaming | 96.38% | 96.38% | 96.38% | 96.38% |
| Mental | Nolimit City | 96.08% | 96.08% | 96.08% | 96.08% |
| Book of Dead | Play'n GO | 96.21% | 96.21% | 96.21% | 94.25% |
| Big Bass Bonanza | Pragmatic Play | 96.71% | 96.71% | 96.71% | 96.71% |
Key finding: Crypto casinos generally run slots at default (highest) RTP. This is a significant advantage over many fiat casinos, which frequently deploy reduced RTP tiers. The exception is occasional Play'n GO titles where operators may select lower tiers.
How to Check a Slot's RTP at Your Casino
Method 1: In-Game Info
Most slots display their RTP in the game information or help menu. Look for a "?" or "i" icon, then navigate to the rules or paytable section. The RTP should be listed — this is the actual RTP running at that casino, not necessarily the default.
Works for: Pragmatic Play, Hacksaw Gaming, Nolimit City, Play'n GO
Method 2: Provider Documentation
Slot providers publish official RTP values in their game sheets. Cross-reference the in-game RTP with the provider's published default to determine if the casino is running the highest tier. If the in-game value is lower than the published default, the casino has selected a reduced configuration.

RTP FAQ
Can casinos change slot RTP?
Yes. Most slot providers offer operators multiple RTP tiers. The casino selects which tier to deploy. This is why the same slot can have different payouts at different casinos. Crypto casinos generally run higher tiers than fiat casinos, but it varies. Always check the in-game RTP display.
What is a good RTP for an online slot?
Anything above 96% is considered good. The industry average is approximately 96.00-96.50%. Slots above 97% are excellent but rare. Below 95% should be avoided unless you specifically want the game's features — you are paying a significantly higher house edge.
Do crypto casinos have higher RTP than fiat casinos?
Generally, yes. Crypto casinos operate with lower overhead costs and tend to deploy slots at default (highest) RTP tiers. Many fiat casinos, especially those in regulated markets with high taxation, deploy reduced RTP tiers to maintain margins. This is one of the underappreciated advantages of crypto casinos.
