What does RTP mean?
RTP, or Return to Player, is the theoretical percentage of all money staked on a slot that is paid back to players over millions of spins. A 96% RTP slot returns £96 for every £100 wagered, on average, over the long term.
What is volatility?
Volatility describes how often and how large wins tend to be. Low volatility slots pay smaller wins more frequently; high volatility slots pay less often but with bigger potential wins. If your bankroll is small, lower volatility is generally safer.
RTP of popular UK slots
Starburst: 96.09%. Book of Dead: 96.21%. Big Bass Bonanza: 96.71%. Gonzo's Quest: 95.97%. Always check the in-game information panel, as some operators run slightly different RTP configurations of the same title.
How to use these numbers
Choose slots rated 96% or higher, set your stake at 1-2% of your bankroll per spin, and decide your win and loss limits before you start playing. This is the most practical way to make your session last longer.
