Long-run meaning
RTP is expected prizes divided by total qualifying wagers over an enormous sample. Expected loss is total action multiplied by one minus RTP.
Recycled wins create new action, so coin-in can greatly exceed cash inserted.
Multiple settings
A supplier may certify the same title at several return settings. Casinos or jurisdictions select among approved configurations.
Denomination, bet level, jackpot participation, or feature purchase can also have separate models.
Evidence
Use the game help screen, regulator filing, supplier documentation, or other configuration-specific evidence. A review site’s title-wide number may not match the machine.
When the exact setting is unavailable, label it unknown rather than inventing precision.
Comparisons
Compare RTP under equal assumptions, then consider volatility, pace, and required wager. A higher RTP at a much larger wager can create greater expected hourly cost.
Promotional value should be measured separately unless explicitly included.
The number worth comparing
For Slot RTP and Game Configuration, without a published PAR sheet, exact volatility and feature contribution are usually unknown; the help screen can confirm rules but not every probability.
For Slot RTP and Game Configuration, keep the rules and denominator fixed. A percentage per initial wager is not interchangeable with one per average total action.
