Payout Slot Machines

Highest Payout Slot Machines: How to Find Slots with the Highest RTP (Return to Player)

If there’s one thing we adore more than fascinating slot slots, it’s slots that are more likely to pay out.

Did you know that every slot machine game has an official Return to Player (RTP) number, which represents the proportion of wins a player is supposed to achieve? It’s a terrific approach to determine which slot slots are the most generous.

Obviously, the casino wants to generate a profit; hence the RTP of all slot slots should be less than 100 percent. Therefore, you should seek out a slot with a payout percentage as near to 100 percent as feasible.

This article lists the top 10 RTP slots , many of which are available at TwinSpires Casino. Even though they are not currently available online, we are always adding new games to our repertoire, so keep a lookout for fresh arrivals.

Ugga Bugga 99.07% RTP – Playtech

This unusual offering is not like regular slots. It resembles video poker in that you must form winning symbol combinations but have the option to retain a symbol space, which then affects all 10 lines. It requires some adjustment, but the phenomenal RTP ensures that you won’t go broke trying.

Mega Joker, 99% RTP – NetEnt

Fans of slot slots like this NetEnt classic. When wagering the maximum number of coins, the RTP is unmatched. The base game features three reels and a music reminiscent of slot machines from the 1960s. You may collect your earnings from the main game or use them to play the Supermeter bonus game. In addition, there is a progressive jackpot function.

Ooh Aah Dracula, 99% RTP – Barcrest

Match winning frightening symbols in Count Dracula’s infamous castle in this slot machine with a gothic atmosphere. There is a Graveyard Bonus, a Super Graveyard Bonus, and a Heart Attack Bonus to warn you that things may not be as they appear.

Jackpot 6000, RTP 98.8% – Netent

Similar to Mega Joker, this is an old-school traditional slot where you may play the base game with three reels. To unlock the Supermeter bonus game, however, you must play the maximum number of coins.

The Catfather, 98.10 percent Return on Investment – Pragmatic Play

In contrast to the Godfather’s violence and guts, the Catfather slot machine is more cuddly and adorable. Five reels spin in either way, with cats making winning lines in any direction. Initiate the free spins feature and quadruple any wins. Purrfect!

Blood Suckers, 98% RTP – NetEnt

With a respectable RTP of 98 percent, Blood Suckers should not leave you bankrupt. With five reels, 25 paylines, scatters, and wilds, the player attempts to slay vampires by selecting coffins containing monetary rewards. It is not a cheerful game, but it is a lot of fun.

Jokerizer, 98% RTP – Yggdrasil

Here, the slot machine manufacturer with the improbable name came out on top. Jokerizer is a traditional fruit machine including cherries, lemons, bells, and sevens. Look for the Jokerizer and Mystery Win modes.

Rainbow Riches Pick n Mix, 98% RTP – Barcrest

This is a sequel to the bestselling Rainbow Riches. You pick which bonus games to play, assuming, of course, that you can activate them. Target the Pots of Gold Bonus, the Magic Mushroom Bonus, and the Road to Wealth Bonus.

Starmania, 97.87% RTP – NextGen

Why Should You Consider Slot RTP?

Occasionally, the RTP of slot slots may not appear to make a significant impact. In light of the preceding, a slot machine with an RTP of 97 percent and another with an RTP of 99 percent might theoretically return the same amount after only a few spins.

However, that is not how it should be viewed.

Instead, RTP should be seen as the probability of winning the game. Therefore, the casino slot machines with the highest RTP provide you with a greater chance of winning, or at least of recovering a bigger portion of your investment.

This is especially true if you frequently play the same video slot. Over time, the game’s return will become more consistent and approach its stated RTP.

The same game developed by the same game developer may have varying RTPs at various casinos. This is due to the fact that these developers provide casinos with a selection of RTPs. However, an RTP of 97% or 99% will not make a significant impact on players in the short term, so you shouldn’t be too concerned.

RTP & Volatility

Whether you’re going to play one of the highest or lowest RTP slots, the game will include additional values you should be aware of… Volatility is the most significant factor.

Volatility refers to the frequency with which a slot machine issues payouts over the short term, and its value might be high, medium, or low.

  • High volatility results in occasional but greater payouts.
  • Low volatility results in frequent but modest payouts.

Sometimes, volatility and variance are also confused. But variance, although referring to essentially the same thing, is concerned with the long term.

Together, volatility and RTP provide a more accurate picture of what to anticipate in terms of payouts.

Consequently, the highest RTP slots, which also have high volatility, will continue to provide payouts at rare intervals, but the quantity of those payouts should, in theory, be greater due to the higher amount that must be redistributed.


It depends on your budget whether you choose a game with high or low volatility! If your bankroll is large enough to withstand numerous consecutive losses, it may make sense to play one of the best RTP slots with high volatility, as payouts tend to be greater when they do occur. If you have a smaller bankroll, though, a slot machine with a high RTP and minimal volatility might help you earn money back more quickly. There is no assurance of either a win or a loss.

Slot RTP Explanation

RTP is not usually straightforward, especially since it has been revealed that RTP is not always the same for every spin. But the explanation for this is fairly straightforward.

Imagine your monthly trip to the grocery store. There may be moments when you reach 50 kilometers per hour while driving to the grocery store and other times when you’re trapped in crawling traffic. At the conclusion of your voyage, you’ll have an average speed that represents both your slow and rapid driving periods.

RTP is the same. It is measured over a million or perhaps a billion spins. Therefore, while the RTP must be accurate and validated, it does not guarantee that you will always get that proportion of your wagers on any particular spin or series of spins.

Let’s use Book of 99 from Relax Gaming to show this topic. This is one of the slots with the highest return-to-player percentages in the world, at 99%. Theoretically, players should now receive 99 cents for every euro, pound, or dollar theory. However, a player may risk €/£/$100 in a single session and receive 30% of that back, while another player may strike the maximum jackpot of 5,000 times their stake with a €/£/$10 wager.

You may encounter winning or losing streaks when playing both slots with low and high RTP. This may give you the impression that anything is amiss with the slot or that the casino has rigged it. This almost seldom occurs, especially if you choose legitimate and regulated casinos. This is; instead, the RTP is carrying out its duties.

How is RTP determined?

In theory, it’s easy to figure out RTP. The formula for RTP, which might make you feel like you’re back in physics class, is:

(the amount gained by players) / (how much is gambled by players)

In one of the best RTP slots, such as Blood Suckers by NetEnt, players receive 98c/p for every €/£/$1 wagered, resulting in an RTP of 98 percent.

As previously stated, the RTP is a weighted average across several spins and does not indicate what you would get on a single spin. If you were to compute your own RTP, you would likely discover that some spins result in a considerably lower percentage while others result in a much larger %.

Moreover, casinos cannot arbitrarily alter the RTP of a game. In reality, developers go to considerable measures to guarantee that a game is legal and fair.

The House Edge and RTP

Percentages are, by definition, out of 100 percent; therefore, even the best RTP slots game, Mega Joker by NetEnt, with an RTP of 99 percent, leaves 1 percent on the table.

This 1 percent is known as the house edge, and it results in an average casino profit of 1c/p for every €/£/$1 wagered.

Historically, slot machines at land-based casinos had an RTP between 70 and 90 percent, giving them one of the highest house edges of all casino games. Slot machines offer a large house edge when compared to the 1.06 percent house edge on a Banker bet in Baccarat or the 5.26 percent house edge on a Double Zero in online roulette.

Despite this, the RTP and house edge of online video slots are distinct: although the average RTP is 95%, the average house edge is just 5%. However, this is still greater than the majority of other online casino games.

This is why we usually recommend playing video slots with the highest RTP – 96 percent or more, ideally 98 percent or more. These best RTP slots substantially lower the house advantage, increasing your chances of winning.

RTP (theoretical)

Some slot slots may mention the RTP as “theoretical.” This can, therefore, be perplexing to players, prompting them to question whether the promised RTP is truly true.

What developers mean by “theoretical RTP” is precisely what we’ve already discussed, namely that not all players will receive the same percentage back.

This is especially true in slots with the highest RTP and the highest volatility, where losing streaks are more likely.

Low RTP and the Malta Gaming Authority

It is noteworthy to note that one of the most popular casino licenses currently permits slot slots to have an RTP as low as 85%.

The Malta Gaming Authority (MGA) contends that this will bring the RTP of online slots closer to those of their land-based equivalents. As we have seen, land-based slot machines have a lower RTP on average. This is because physical space is at a premium, necessitating that the game generates a greater profit than online slots.

This makes online casinos with the best RTP slots even more exceptional.
