Every number on this site — RTP, volatility, maximum win — comes from somewhere, and you deserve to know where. This page describes how the SlotRandomizer database is built, what “verified” means here, and what the data can and cannot tell you.
Source Hierarchy
We use a strict priority order when recording slot specifications:
- 1. Official provider documentation — game pages, published game sheets, and provider client areas. Where a provider publishes the figure, that figure wins over any other source.
- 2. Reputable secondary databases and review sites — used when official specifications are not publicly accessible, typically for legacy titles or smaller studios. These entries carry lower confidence.
- 3. In-game info screens — used for spot-checks and dispute resolution, with the caveat that the visible figure reflects one casino’s configuration, not necessarily the maximum.
What “RTP” Means in Our Database
Where a game ships in multiple RTP configurations, we record the highest published configuration and label it accordingly. Casino operators choose which configuration to run, so the RTP inside the game at your casino may be lower than the figure shown here. This is why every result card carries a configuration note, and why we repeat the same advice everywhere: verify the figure in the game’s info screen before playing.
Volatility Ratings
Where providers publish an official volatility scale (for example, a five-point scale), we record the official rating. Where only word ratings exist (“high,” “medium”), we map them to a comparable scale for filtering purposes and treat them as approximations. Volatility describes the shape of a game’s payout distribution — it is a design property, not a prediction of session results.
Update Cycle and Corrections
The database is maintained through periodic provider-catalog reviews, manual checks of new releases, and corrections submitted by users. When a reader reports an error, the entry is re-checked against the source hierarchy above before any change goes live. Found something wrong? Tell us — data corrections are the most useful mail we get.
Known Limitations
- Some fields remain incomplete, particularly for legacy titles and small studios without public documentation.
- Provider counts and catalog totals are approximations at any given moment — games are released, reworked, and retired continuously.
- Maximum win figures are theoretical caps from provider specifications; individual casinos may enforce lower payout limits.
- No figure on this site predicts short-term results. RTP and volatility are long-run statistical properties.
Independence
Casino relationships do not influence which game the randomizer selects or how any game’s data is recorded. Some casino links may be affiliate links; the data layer and the commercial layer are kept separate by design.
