Return figure
The stated RTP is matched to the provider's listing and the in-game rules, including any condition attached to it.
Rupert treats every game page as a set of claims to be sourced. He checks each multiplier, limit and rule against the provider's listing and the game's own screens, and he sends a page back until the numbers match.
Six checks run on every page before it is published, and again whenever the provider updates the game.
The stated RTP is matched to the provider's listing and the in-game rules, including any condition attached to it.
Step values, maximum multipliers and the conditions behind them are compared with the paytable line by line.
Every rule about boosters, cash-out and autoplay is checked against the wording on the rules screen.
Each pound example is recalculated independently, and the result must match to the penny.
Stake limits, win caps and release dates are only stated when a source publishes them; otherwise the page says they vary.
Claims that imply certainty or guaranteed outcomes are removed, and each page must carry a clear safer-gambling note.
I began in editorial fact-checking, where the rule was simple: every claim needs a source you can point to. Later I spent several years reading game documentation, rules sheets and certification summaries for a living, and I saw how easily a figure changes as it passes from one page to the next.
Game data is especially fragile. A volatility label is rounded off, a maximum win is copied without its condition, a bet range is repeated long after an update. Each shortcut looks harmless, and together they leave readers with a picture the game does not match.
So my job here is narrow and deliberate. I do not write the pages; I try to break them. I compare each claim with the provider's listing and the game's own information screen, and when two sources disagree I say so on the page instead of choosing the more exciting one.
If a source does not publish a figure, the page says so instead of guessing.
The author supplies a source for every figure, and I open each one myself.
I compare the draft with the sources and mark every mismatch, however small.
Marked drafts go back, and the author answers each point before anything moves on.
I approve the page only when every mark is closed, and the update date is recorded on it.
