Every review site quotes RTP figures, and not all of them come from official documents. The deltabet88 casino article covers the basics; this guide looks at how to verify a number before trusting it.
Where an official number comes from
One source: the game's info sheet from its provider, or the certification page of a licensed regulator. Everywhere else — including screenshots without links, reviews without sources, and "verified" claims without a named tester — is marketing, not data.
Signs a figure deserves doubt
- Round "pretty" numbers (97%, 98%) with no supporting document.
- An RTP claim higher than the official version of the same game.
- Terms like "guaranteed wins" or "hot patterns" — neither has a technical meaning.
- Numbers that change with promotions rather than game versions.
Volatility: the half of the story often forgotten
RTP without volatility is a map without a scale. Two games with identical RTP can feel opposite: one pays small and often, the other holds out for a long time then pays big once. For small budgets, low volatility is usually the more sensible choice.
Using the number correctly
The official figure exists to compare games, not to predict a session. Short sessions are ruled by variance; no number changes that. Set a budget before starting — the responsible-play notes summarise how, and the same verification standard applies when judging casino bonus terms.
