It makes sense to search for the best RTP slots to improve your chances of winning money online. After all, the highest RTP slots mean more money is returned to the players, reducing the house edge simultaneously.
In this article, we introduce you to the top ten highest RTP slots in 2024, explaining where to play them at online casinos and what features you can expect within the various games. Some of the games on this list have an RTP of 99% or more, highlighting their impressive value for money.
But first, some housekeeping. What is RTP in slots, and why is it important? Let’s take a quick look.
What Does RTP Mean in Slots and How is it Calculated?
RTP means a return to player, which refers to the amount of money a particular slot game pays out. So, for instance, if a slot has a return to player percentage of 97%, it means that for every $100 spent on the slot, $97 is returned to the players. This example also means that the slot has a house edge of 3%. RTP is important as it helps you to select games that match your gaming preferences while looking for good value for money.
RTP is calculated by game developers during extensive testing, where millions of spins are simulated to determine the expected return. It compares the total amount of money bet by players to the total amount of money paid out.
Now that we’ve run through the basics, it’s time to introduce the highest RTP slots in 2024, where you can find them, and why you should give them a go.

How We Rank the Best High RTP Slots
RTP Percentage: the Return to Player (RTP) percentage is our primary factor. Slots with an RTP above the industry average of around 96% are prioritized. For example, slots with an RTP of 97% or higher, like Blood Suckers, are highly valued for their potential to offer better returns over time.
Features: we evaluate the variety and excitement of game features. Top high RTP slots provide engaging gameplay with features like Megaways, stacked wilds, bonus rounds, and extra spins. Slots with innovative and entertaining features receive higher ratings as they enhance the overall player experience.
Maximum Win Amount: we examine the betting limits and maximum win potential of each slot.

This ensures that players have the chance to achieve substantial wins.

FAQs About Best RTP Slots
What does RTP mean in slots?
RTP means return to player, and it is given as a percentage. Every slot game has an RTP, and it can vary from casino to casino. Therefore, it’s important to check a slot game’s RTP before gambling so you know what to expect from each game that you play.
The return to player percentage is another way of working out the house edge of each game, and the higher the percentage, the lower the house edge. Therefore, as introduced above, most online players seek out games with the highest RTP percentages, as they pay out more frequently than those with lower percentages.
How does RTP work?
RTP in slot games is relatively easy to come to terms with, and it’s a really helpful metric to understand. Let’s say that a particular slot game has a return to player percentage of 95%. Essentially, this means that for every $100 wagered on the slot, $95 will be returned to the players, while $5 will be kept by the casino.
It’s important to note that as an online player, you will only be playing the game for a fraction of its lifecycle, meaning that you can win or lose in equal measure. The RTP percentage represents how likely a game is to payout and shouldn’t be regarded as a literal metric showing what you will win by playing a slot game.
What is a good RTP for slots?
While every player has their own preferences when it comes to RTP, it’s generally accepted that anything over 95% is considered high. But it’s important to consider variance alongside RTP to get a better understanding of how much money you can potentially win on a slot game.
For instance, a game with a high RTP and low variance will pay out smaller amounts of money more frequently. On the other hand, a game with a low RTP and high variance will pay out larger sums of money less frequently. Ultimately, both types of slot games can be attractive to online players, meaning that whether a game’s RTP is good or bad is subjective and differs from player to player.
How to find RTP on slots?
Thankfully, finding the RTP of a slot game is straightforward. Most online casinos publish the game’s RTP directly on their site, enabling you to see what the game pays out before placing a bet.
However, if you visit an online casino and can’t find the RTP, a simple Google search will help you find it. One thing to note with this approach is that the same slot game can have different RTPs, depending on the casino on which it is hosted. This is why it’s always better to get the RTP percentage from the casino directly than from a third-party website.
What slot machines have the highest RTP?
There are lots of slot machines with RTP percentages of 95% or more, but as introduced above, some of the highest RTP slots include:
- Ugga Bugga – 99.07%
- Mega Joker – 99.00%
- Ooh Aah Dracula – 99.00%
- Jackpot 6000 – 98.80%
- The Catfather – 98.10%
- Bloodsuckers – 98.00%
- Jokerizer – 98.00%
- Rainbow Riches Pick N Mix – 98.00%
- Starmania – 97.87%
- White Rabbit Megaways – 97.77%
New slot games are released all of the time by the biggest software developers in the business, so it’s always worth checking out new games and their associated RTP percentages. You can mix things up and try out different games, as it keeps things interesting when playing online slots and provides you with more chances of winning, particularly when you play the best RTP slots online.
