Best Online Slots with the Highest RTP
Every player who tries online slots hopes to strike a lucky combination and walk away with impressive winnings. Since licensed slots operate based on random number generation, everyone faces the same chances of winning, don’t they? Actually, the reality is a bit more complex.
RTP is an important metric that helps determine how likely it is to win in a particular game. Find out what it means and discover the best online slots with the highest RTP!
What Is RTP And Why Is It Important?
If you’re interested in having some quick fun, you probably have no intention of learning the terminology and in-depth mechanics of slots. However, there are some things that every person with the slightest interest in winning should know, including popular slot machine features and the RTP of the games they’re playing. This will help calculate the odds before spending your money.
RTP means Return to Player. It’s measured in percentage, and it shows how much of the money you invested the slot machine is bound to pay you back over time. Take a look at this example:
-
The RTP of your chosen slot stands at 98%.
-
It means that for every $100 you spend, you’ll return around $98.
-
It won’t happen immediately, but if you play for a certain period, this is how much you’ll be able to get back.
Don’t expect this pattern to work all the time, though. Some players are going to win, which will tilt the balance in their favor. To compensate for it, other people are going to lose more often than the RTP presupposes.
Still, the higher the RTP is, the more money you’re likely to return. This is why more experienced gamblers want to find slots like these.
Top Online Slots with the Highest RTP in 2025
Which slots with the best RTP should you play in 2025? Here’s a list of the top options.
Mega Joker – NetEnt
There are slots with a high RTP, and then there is Mega Joker from NetEnt. This is a 2x3 slot with an RTP of 99%, one of the highest numbers in the history of gambling. It has a catch, though: Mega Joker comes with several modes. To get the highest RTP, you need a supermeter mode, which requires placing higher bets.
This way, you will win bigger sums across multiple occasions, but you can lose some substantial amounts, too. You can try safer modes, but the RTP will be somewhat lower there.
Jackpot 6000 – NetEnt
NetEnt is known for offering high RTP to its players, and Jackpot 6000 is yet another game with the rate of 98.9%. You need to bet a maximum number of coins to play with this RTP, but for many players, the end result is worth it. The slot itself has 3 reels and 3 rows, and it has a nostalgic feel since it’s done in a vintage style.
The Catfather – Pragmatic Play
Who doesn’t love cats? Pragmatic Play decided to make its players happy by introducing The Catfather, a funny cat-mafia game with an RTP of 98.10%. It’s a 3x5 slot, and if you enjoy the cat theme and the excitement of winning often, you should definitely give it a go.
Book of 99 – Relax Gaming
Book of 99 has 5 reels and 3 rows, and an amazing RTP of 99%. This slot revolves around changing history by battling Gods and collecting secret books. If you get 99 of them, you’ll receive a gift in the form of 10 free spins.

Pros and Cons of Playing High RTP Slots
Playing slots with high RTP is definitely a great idea, but it has some drawbacks. You need to learn about them, too, to make an informed decision as to whether you should try these games or not.
Pros
-
Better odds in the long term. The more you play high-RTP slots, the more money you return.
-
Less aggressive in terms of losses. The losses don’t bite as harshly since high RTPs are more generous.
-
Excellent for quick bonus wagering. If you need to wager your bonus with minimal losses, playing high-RTP slots is a smart idea.
Cons
-
Frequent low volatility. While slots with higher RTP allow winning more frequently, these wins tend to be smaller than usual due to low volatility.
-
Difficult to find. It’s hard to find good slots with truly high RTP; you need to try quite a few licensed casinos to settle anywhere.
-
Fewer bonuses available. Since slots with better RTP bring victories more often, the providers offer fewer bonuses to players.
Informed choices always lead to better outcomes. Let’s take sports betting: if you know nothing about basketball, you can try to predict who’ll win the Hugh Durham Award among the coaches, but most likely, you’ll choose wrong. Winning in slots without any prior knowledge is much simpler, but even then, understanding what RTP means and what its pros and cons are is essential for getting bigger sums with higher frequency.
