01A percentage of stakes, not of your deposit
Theoretical RTP comes from the game's mathematical design. Actual RTP for a measured sample is total prizes divided by total stakes. These figures describe different things: a design expectation and an observed result over a specified sample.
A hypothetical 96% RTP means an expected return of 96 units per 100 units staked over the long run. It does not mean that depositing 100 guarantees a remaining balance of 96. Stakes may include money staked again after earlier wins.
Theoretical RTP 96% → house edge 4% in this simplified model. Neither percentage forecasts a single session.
02How volatility differs from RTP
Volatility describes the spread of possible results. Games with similar theoretical RTP can distribute prizes differently: some patterns involve smaller, more frequent prizes; others include rarer, larger prizes and wider fluctuations. A volatility label is not a prediction of when a win will occur.
In the simple example above, the house edge is 4%: 100% minus 96%. This is an average mathematical advantage, not a charge deducted from every round. A short sequence can differ substantially from the long-run figure.
03What the number cannot establish
For independent random rounds, a run of losses does not make the next round more likely to win. Playing longer does not create a deadline by which an individual's losses must be returned. No RTP figure removes the possibility of losing the full amount staked.
Read the rules for the exact game version and distinguish theoretical RTP from any displayed historical statistic. A percentage alone does not establish an operator's licensing, treatment of complaints or ability to process withdrawals.
What to check
- Whether the figure is theoretical or measured, and which game version it describes.
- Whether a historical figure states its period and sample size.
- The difference between return, volatility and the probability of a particular prize.
Questions, answered
Does 96% RTP mean a 96% chance of winning?+
No. RTP describes the value of returns relative to stakes over the long run, not the chance of any individual winning result.
Can past losses show that a win is due?+
No. In an independent random game, earlier losses do not improve the probability of the next round.
