Understanding RTP & Volatility in Online Pokies

SC
Pokies & Game Expert · Updated May 2026

RTP and volatility are the two most important mathematical concepts for any pokie player to understand. Together, they determine how much a game pays back over time and how wildly your results can swing in any individual session. This guide explains both concepts in depth with practical examples.

What Is RTP?

RTP (Return to Player) is the percentage of all wagered money that a pokie is mathematically designed to return to players over its lifetime. It is calculated across billions of simulated spins during game development.

Critical point: RTP is a long-term average. In any single session, your actual return can be anywhere from 0% to 10,000%+. RTP only becomes predictable over millions of spins.

What Is Volatility?

Volatility (also called variance) describes how a game distributes its payouts. Two games with identical 96% RTP can feel completely different depending on their volatility:

How to Use RTP & Volatility Together

RTP at Australian Casinos: What to Watch For

Many game providers offer casinos multiple RTP settings. For example, Pragmatic Play pokies might be available at 96.5%, 95.5%, or 94.5% RTP. The casino chooses which setting to use, and different casinos may run the same game at different RTPs.

Always check the in-game info screen before playing. The displayed RTP tells you exactly what setting the casino has chosen. If the RTP is significantly lower than the provider’s default, consider playing at a different casino.

FAQ

In the long run, higher RTP means you lose less per dollar wagered. In any individual session, anything can happen. A 94% RTP pokie can produce a massive win, and a 98% RTP pokie can result in a total loss. The difference becomes meaningful over hundreds of hours of play.

Not necessarily. Low volatility provides steadier play but smaller wins. If you have a larger bankroll and enjoy the excitement of big-win potential, high-volatility pokies may be more enjoyable. Match volatility to your bankroll size and risk tolerance.
