What is RTP?
RTP or Return to Player, is the amount you receive from your bet when you win a game. A percentage figure usually represents Return to Player percentage, and it is different for each game. In table games, RTP is the exact amount you will win from a bet.
For example: Blackjack has a 99% RTP, making it one of the highest RTP paying games online. If you placed a £100 stake and won, you will likely get back £99. Many players ask what does RTP mean, or what is RTP, and this example clarifies it. For those wondering what does RTP mean in gambling, or what is RTP gambling, it’s essentially a measure of how much a game pays back to players over time.
What is volatility in casino games?
Most casino review experts in the UK usually include volatility in slots. Unfortunately, research proves that many slot players must pay more attention to game volatility rates. After all, it is one of the most crucial decisions players must make when choosing what to play. So, what is volatility? Volatility, also referred to as variance, is the frequency of wins in a game. Today, there are three major types of volatility:
High: A game whose wins happen less often but offer the highest payouts.
Medium: The game provides a fair share of small and occasional big wins. The frequency of payouts is moderate.
Low: In low-volatility games, the wins are frequent but in smaller amounts.
Here is a table showing how each type of variance affects a player’s risk and the size of your win.
Variance/Volatility | Win Frequency | Player’s Risk On Stake | Amounts won per bet |
---|---|---|---|
Low | High | Low | Low |
Medium | Moderate | Medium | Low/Medium |
High | Low | High | High |

Now that you understand the basics of Return to player and volatility, we can examine how variance and RTP can affect your gaming strategy and odds of winning.
If you don’t have a considerable bankroll
If you have a low bankroll and want to win more during your gaming session, it would be better if you played a low-volatility and high RTP slots game (with a 97% RTP or more). This strategy is used by seasoned players to spread their stake across multiple rounds and play longer. Also, it is advisable to choose high RTP games that allow a minimum bet of 0.10. Many ask what is a good RTP for slots, and generally, anything above 96% is considered good.
If you have a medium-big bankroll
Players with a larger bankroll can choose medium or high-volatility slots with a high RTP (any game with a 94% RTP or more). They can also pick games with max bet limits of 50 or more. This is a smart strategy that gives you big individual wins and a generous return to player over time. For those seeking best RTP slots, or highest RTP slots, looking for games in this range is a good starting point.
