Maximizing Your Chances: Understanding RTP in Real Money Slots
The best way to increase your chances of winning and making your playing sessions last as long as possible is by evaluating the RTP percentage of an online slot.
The RTP represents how much a slot will pay back on average over time. For instance, if an online slot has an RTP of 96%, you can expect to receive $96 back in winnings for every $100 wagered.
Most of the best real money slots provide an RTP percentage of around 96%.
High RTP slots, on the other hand, offer an RTP of 97% and above. For this reason, we highly recommend reviewing the RTP percentage before wagering real money.
This will greatly increase your chances of winning and extend your playtime. You might even come across real money online slots where the RTP hovers around 99%.
How Volatility Affects Slot Games that Pay Real Money
The volatility of a real money slot describes how frequently payouts occur. Put simply, it’s a measure of risk as it determines the amount you win and how often the win takes place.
A slot’s volatility can be categorized as low, medium, and high, with each category providing its own strengths and weaknesses
There’s no such thing as the ideal volatility level, as this boils down to personal preference. To better understand the various slot volatility levels, we included a brief explanation of low, medium, and high volatility slots, along with examples.
High Volatility
A high volatility slot will provide a low payout frequency. This basically means that payouts will occur less often.
The counterpoint to low payout frequencies is that the average payout value will be much higher once you trigger a win.
So, you can say that slots with high volatility don’t pay out too often but provide bigger prizes once a win occurs. Some of the best high-volatility slots include:
- Fluffy Favourites
- Book of Dead
- Gold Blitz
- Bonanza
- Big Bass Splash
Medium Volatility
A medium volatility slot provides a well-balanced playing experience where you will receive a regular stream of medium-sized wins.
The majority of the best real money slots fall into this category, as software providers understand that you want an even balance between potential rewards and risk. Some of the most popular slots with medium volatility include:
- Magic Jokers
- Rainbow Riches
- Eye of Horus
- 9 Pots of Gold
- Fishin’ Frenzy the Big Catch
Low Volatility
A low volatility slot will provide a high payout frequency. This essentially means that wins will occur more often compared to medium and high-volatility slots.
It’s worth keeping in mind, however, that the payouts will be much smaller. For instance, a low volatility slot might provide a 70% payout frequency, but the prizes will only be worth 60% of your bet size. Some of the most popular low-volatility slots include:
- Agent Jane Blonde Returns
- Clover Rollover 2
- Starburst
- Fishin’ Frenzy Jackpot King
- Butterfly Staxx
You will notice that the volatility for the best real money slots can also provide two volatility levels, such as low-medium volatility or medium-high volatility. This will provide certain aspects of each volatility level to provide a more personalized playing experience, depending on your play style.
