WHAT IS RTP AND VOLATILITY?
WHAT IS RTP AND VOLATILITY? If you’ve ever spun the reels of one of our slot games or sat down at one of our live casino tables, you’ve probably come across the terms RTP and volatility, but what do they actually mean? RTP
Let's start with RTP! RTP stands for Return-to-Player, and now you may be wondering, “Okay, I get that it's return to player, but what does it mean?”
Well, the RTP casino meaning represents the average amount of money that online slots or live casino games pay back (or return) to the player over a long period of time, and they're displayed as a percentage. So what this means is that a slot with a 98% RTP will pay out £98 of every £100 wagered on average. However, it's important to note that RTP is based on millions of spins or rounds on that game, so you shouldn't expect to get £98 back of the £100 you're wagering on a particular game - you may hit a winning streak and make a profit or run into a stretch of bad luck and win nothing. Volatility
Low - These slots consistently pay out lower wins. Best for players with the lowest risk appetite. Low to Medium - These slots generally pay out lower wins but more frequently. Best for players with a low risk appetite. Medium - A mixture of big and small wins at a more varied frequency. Best for players with a balanced risk appetite. Medium to High - These slots may pay out higher wins but less often. Best for players with a high risk appetite. High - These slots have the potential to pay out the highest wins but much less often. Best for players with the highest risk appetite. And, like RTP, it's important to remember that a slot's volatility level is based on the average experience. All slots can pay out both small and big wins. Starburst which has a low volatility, meaning it generally pays out lower wins but more often, while Book of Dead is has a high volatility meaning it pays out higher wins, but generally less often.
