A slot advertised at 96% will almost never return 96% to you. Not in a session, not in a month, and quite possibly not across your entire history with the game.
That is not a criticism of the figure. It is what the figure means, and the difference between the published number and what you actually experience is the most consistently misunderstood thing in casino maths.
Theoretical Is a Limit, Not a Forecast
A published return comes from certification testing, calculated across millions of simulated rounds. It describes where results converge as the sample grows without bound.
Actual return is what happened in your rounds. It is a single draw from a distribution centred on the theoretical figure, and over any sample a person could realistically play, that draw scatters widely.
The table below shows the shape of it directionally. These are illustrative bands, not precise intervals, because the true spread depends heavily on the game’s volatility.
