Bojoko helps you find the highest-RTP slots

On Bojoko, you'll find everything you need to know about slots. We have built tools to ease your searches, reviewed slots to see which are worth it and written an extensive slots guide to help you understand how slots work under the hood.

Here on Bojoko, we strive for credibility and honesty. We work closely with game developers and casinos, and in most cases, get our data straight from the source. They supply us with accurate details, which we then list on Bojoko, but they don't have any say on the ratings. That is where our experts come in.

Our experienced experts test the casinos out and review them properly. They don't hide behind anonymity, but rather give you their honest, accountable opinion. They don't just show you what is good, but also tell you what is wrong.

What is RTP?

RTP stands for Return To Player. It tells you statistically how much money the game will give back to the players as wins.

EXAMPLE: A game has an RTP of 97%. On average, it will give the players 97 pounds as wins for every 100 pounds staked.

This simply means that the best paying slot, in the long run, is the one with the highest RTP. Of course, things aren't simple when you look at a regular short session. There are things like volatility and win rate which can change things around. RTP is calculated from millions of spins, which is much more than any real-life play session.

To mix the pot a little more, you can't just blindly follow the RTP to see which slot will pay out in the long term. Some games, like progressive jackpot slots, have a surprisingly low RTP. This is a bit of an anomaly that is caused by the ever-increasing jackpot. That being said, people don't usually play jackpot games for their RTP, but rather for the possibility of a single big win.

List of the top RTP slots

Slots have come a long way when it comes to the RTP. Back in the day before online slots, it was common to have fruit machines with an RTP of 75-85%. The players didn't have many options, so you played what you could. Then the era of remote gambling began and everything changed.

Just two decades later, slots had an average RTP of around 96%. If a developer's new slot dips below that, the game better be amazing in every other aspect.

You can check out some of the highest RTP slots in the world right here on Bojoko.

One thing you might notice quickly is that they are very simple games. They usually don't have many bonus features or may even be actual three-reeled fruit machines. This is because it is easier to make a balanced game with a big RTP if it doesn't have volatile features. It's simply better business for the casino.

Highest RTP games

If you go by RTP alone, the best games to play aren't always slots. Sure, some slots have come close, but the highest RTP can still be found elsewhere.

If you can bet on it, an honest coin flip has an RTP of 100%.

In a coin flip, Neither party has any edge and if you play long enough, you get back exactly what you put in.

Let's be real. No casino is going to offer a game, where they don't have the edge. Why would you run a business that has fair odds or even worse, costs you money in the long run? Many casino games have an RTP of well above 90%, but the closest thing to a coin flip mechanically is Baccarat. It doesn't have the absolute highest RTP, but it is just as easy to play. You have the same two options as a player and no control over the outcome.

Baccarat can have as high as 98.94% RTP.

Baccarat has a high theoretical RTP, but this is not always the case. Some casinos will take a bigger fee on the banker's hands. Baccarat has always been a favourite of many high-rollers because of the high chance of doubling your bet. It is like betting on red or black in Roulette, but without that zero sector to mess things up.

Other great choices are Blackjack using Basic Strategy, video pokers and French Roulette. These are all heavily casino and developer dependent. You need to check the RTP for that particular game you want to play yourself. Here are some of possible RTP's:

NOTE: Many video pokers require you to play with a very specific bet level to get the high RTP. Usually it is the most expensive bet you can make in that game.

RTP and bonus wagering

One of the best uses for slots with high RTP is filling up those bonus wagering requirements. This is especially good if you find a game that also has low volatility.

A game like this should return most of the money you put in it and do it fairly reliably. You might not get ahead, but at least you get to play a lot of rounds.

Casinos know about this and they try to stop you from doing it. If you read the bonus terms, you can often find a list of games that you can't play while filling up a wagering requirement. Every single one of these prohibited games has a high RTP. In the player's eyes, the best casinos don't restrict these games.

Check out our bonus page for more detailed info about game restrictions while wagering.

Volatility vs variance vs RTP

RTP is all about mathematics and long-term calculations. This is why some games might feel like they suck every last penny out of you even if they should have a massive RTP. What you experienced is variance and not the effect of RTP.

Slightly simplified explanation is that variance is the statistical value of how much a system deviates from the average. In slots, it just means that in a short session the slot might not behave in the same manner as it does in the long run.

Developers often call statistical variance of a slot its volatility. A slot with low volatility will not deviate much from the average but a high volatility slot will.

To be fair, we are splitting hairs here. Unless you are a mathematician, variance and volatility are basically the exact same thing.

RTP is usually calculated over millions and millions of spins. The random number generator can produce an insane amount of possible spins and the RTP is the result of all of them. No human can ever play this many rounds. That is why when we play, we have to deal with variance.

Variance can be a player's best friend, as it is the reason why you can win. If there is no variance, then the players would always just lose. You would put a pound in and get 97 pence back every single time. Play enough and you lose it all. Variance is what makes it possible to put a pound in and get two pounds back.

You can change the RTP

RTP is not always something that is set in stone. You as the player can actually change it. Some games have a variable RTP and if you know what to do, you can optimise it.

First thing you can do is to look where you play. Most of the slots have the same RTP on every casino, but not always.

EXAMPLE: here are some of the RTP values of the highly popular Book of Dead slot.

This is not something that just old sites do or just the brand new casinos. It is hard to tell without checking out the slot for yourself. Our slot pages always lists the highest RTP that particular slot can have, so it's good to check what is the real RTP on your favourite casino.

Second thing is to read the game rules. Some slots have a variable RTP that is changed by your bet level or activating certain in-game features.

EXAMPLE: In Hotline 2, the number of Hotlines you have active increases the RTP of the entire slot.

Knowing this, you can play a bit more optimised. Find out what is the optimal wager and way to play so you have the best chances.

Conclusion - Does RTP matter?

Now you might be asking yourself, is any of this information important? That is a fair question to ask. Some players want to optimise their play experience and try to do everything in their power to maximise the chances of winning. To those players, finding the highest RTP game or best paying slot is important.

To your average player, RTP is something noteworthy. It's good to know what it is, what it means and which slots have high or low ratings. You don't need to go out of your way to find the best payout, but you might steer clear of the worst ones.

Gambling will always have a negative long-term outcome

In the end, I do have to remind you that gambling always has a negative outcome in the long run. The longer you play, the likelier it is that the casino wins. It doesn't matter how high the RTP is, because it will always be below 100%.

Play slots to have fun, not to fix your financial issues. RTP is something that you might want to keep an eye out for, but you can have fun playing games with lesser percentages.


If you want to optimise your play patterns and go for every single edge, then yes. Otherwise, just play games that are fun for you. Although, some slots with high RTP can be used to fill wagering requirements on casino bonuses.

The highest RTP can be found in the Mega Joker slot by NetEnt. It is closely followed by Jackpot 6000.

RTP is the theoretical average amount that a game will pay out when looking at a large sample size. The game developer looks at every possible outcome the random number generator can produce and see how much the game will pay back to the players.

RTP is the long term average payout percentage. Volatility tells you how much the game will deviate from that. Higher the volatility, the further away the game will sway to both directions.

No. That information is basically useless. The casino can have as high average RTP as they want and it doesn't change the RTP of that one game you want to play. The best payout is more about what choices the players make.
