About RTPBoss
RTPBoss is an independent slot data project. We publish provider-published RTP, volatility, hit frequency and max win figures for 2808 online slots, alongside fact-based crypto casino comparisons. No game studio or casino has editorial input into the data.
What RTPBoss is — and isn't
It is a searchable, documented database of slot mathematics and casino facts, with every figure carrying a source and a confidence level. It is nota casino, not a bonus-farm, and not a place that tells you a game is “due” to pay. We don't sell luck; we publish the numbers.
What we track
RTP and configurable RTP ranges, the implied house edge, max win, volatility, hit frequency, provider, release year and mechanics — plus exact per-mode RTP for games published through Stake Engine. Casino pages carry documented licensing, terms, fees and product facts. When we can't verify a figure, the field stays blank — we never estimate. The full pipeline is set out in the data methodology and source policy.
Why configurable RTP versions matter
Many slots ship in several RTP versions, and the casino chooses which one to run. We list the default or highest published version and flag the configurable range — but RTPBoss normally cannot know which version a specific casino has enabled. Provider-published RTP is not the same as the RTP you actually experience. Always check the game's own paytable.
How casino scores work
The 0–5 score on casino pages is computed, not an opinion: ten documented half-point criteria (years live, licence and regulator quality, originals, sportsbook, rakeback, catalogue depth, documented withdrawal speed and published fee tables). Reviews contain no fabricated first-person testing claims. The full model is on the casino review methodology page.
Who publishes this
RTPBoss is published under named roles rather than personal bylines:
- RTPBoss Data Team — Maintains the game database, validation rules and source records.
- RTPBoss Editorial Team — Maintains guides, explanations and editorial policy.
- RTPBoss Casino Review Team — Reviews documented licensing, terms, fees and product information.
How we make money
Some casino links carry affiliate codes; if you sign up through them we may earn a commission. This never affects RTP figures or casino scores — see the affiliate disclosure.
Limits, corrections and safety
The data can be incomplete or delayed, and older imported values may lack full source history. If you spot a figure that doesn't match a provider's current publication, tell us — see the corrections policy. And please read responsible gambling before you play.
