RTP and volatility, without the hype

These figures describe a game’s design. Neither one predicts what will happen on your next spin.

What RTP means

Return to player (RTP) is a long-run percentage of wagers paid back as winnings across many plays. A hypothetical 96% RTP describes an average return of $96 for every $100 wagered across a very large number of wagers. It does not promise that you will get $96 back from a $100 session. Individual results can be far above or below the long-run average.

The remaining percentage is often described as the theoretical house edge. That is why RTP should never be treated as an income forecast.

What volatility means

Volatility describes how unevenly wins may arrive. A higher-volatility game may have longer stretches without significant wins and occasional larger outcomes. A lower-volatility game may pay smaller amounts more often. Both can lose money, and neither becomes “due” to pay after a losing streak.

How to use the information

Ontario’s PlaySmart explains slot odds, RTP and volatility in more detail. Use the operator’s own game rules for a specific title, and treat any online RTP list as something to verify rather than a guarantee.
