Understanding RTP on online slot machines

When it comes to online slot machines, players often come across the term “RTP”, and even though it’s a very important aspect to take into account when playing slots, many players (even experienced ones) may know what the letters stand for, but not exactly what it means.

Understanding RTP can help you make more informed decisions while gaming, maximize your chances of winning, and enhance your overall online casino experience.

So, do you know what RTP means, and why is it important? if not, it’s your lucky day since we will delve into the concept of RTP on online slot machines in this article, so keep reading!

What is RTP?

RTP, or Return to Player, is a slot machine term that serves to indicate the percentage of wagered money that a slot machine will pay back to players over time.

It is represented as a percentage and is calculated based on extensive statistical analysis and millions of spins.

As we went over in our article about “How online slot machines work”, to better understand this concept, we need to see an example. So, let’s say if a slot machine has an RTP of 98% (which is a pretty good RTP), it means that, on average, players can expect to win back $98 for every $100 they wager over an extended period.

An example of an online slot with this RTP is Blood Suckers from NetEnt, which is very popular slot among online gambling enthusiasts.

It’s important to note that RTP is a theoretical value and does not guarantee individual winnings or losses because, once again, it’s a calculation based on millions of spins and that’s where your “luck” comes into play.

Why is RTP relevant?

RTP is an essential factor to consider when choosing an online slot machine because it gives players insight into the potential returns they can expect from their wagers, and it basically tells them if the slot is worth it or not, at least in their own personal opinion and preference.

Keep in mind that reputable online casinos will always display the RTP percentages of their slot machines in order to provide transparency and allow players to make informed decisions. So, if you are looking forward to playing on an online slot and don’t seem to find its RTP anywhere, you may want to skip that slot, or online casino as a whole.

It’s also worth mentioning that you should not confuse RTP with the volatility or variance of a slot machine. Volatility refers to the level of risk associated with a particular game, and it affects the frequency and magnitude of wins. High volatility slots may have lower RTPs but offer the potential for significant payouts, while low volatility slots may have higher RTPs but provide smaller, more frequent wins.


Understanding RTP is essential for anyone engaging in online slot machine gaming since being knowledgeable about it allows players to make informed decisions, choose games that align with their preferences, and maximize their chances of winning.

And while RTP is not a guarantee of individual results, it certainly provides valuable insights into the long-term payout potential of slot machines, making it a very important statistic to keep in mind when playing.

So, as you explore the world of online casinos, keep an eye on the RTP percentages displayed by reputable operators and consider the interplay between RTP and volatility to find the perfect balance between risk and reward.
