What Are High RTP Slots and How Do They Work?

High RTP slots offer higher returns to players by giving back a bigger percentage of wagers placed over a certain period.

This means that the casino house edge is smaller on these games, which increases the winning chances since the casino’s advantage is considerably reduced.

They also provide lower risk and extend gameplay sessions due to more frequent wins and better returns.

However, the best RTP slots may not offer the same opportunities to win big as lower RTP and higher volatility slots. Despite offering larger individual payouts, high-variance slots can be frustrating due to long periods without a payout.

When discussing top RTP slots, a high RTP is typically considered as anything above 96%, while mid-range or average RTP falls between 95% and 97.99%, and anything below 94.99% is considered low.

The choice to play the best RTP slots depends on personal goals and tastes in gambling, considering the preference for frequent or large payouts. As always, only wager what you can afford to lose.

How to Choose the Right One for You?

We hope you now have a better understanding of how RTP slots work – the next step is to find the one that you like to play.

Many factors can contribute to an enjoyable gaming experience, and the RTP is just a small part of a slot’s make-up. Other elements include game mechanics, big-win potential, bonus features, and graphics. Check our table below for a more succinct breakdown:

2. Check our Slot Reviews

Another more convenient option to find out a game’s RTP is to refer to our slot reviews. Our reviews break down the game’s features, volatility as well as payout percentage. Simply use the ‘Search’ tab to look up any specific games.

3. Calculate RTP

If you cannot find access to this information, you can calculate it yourself. You would need to calculate the total amount won divided by the total amount wagered. This option is less practical for individual players, but those who have access to historical data and time can happily analyse the performance of slot games.

How is RTP calculated in slots?

The Theorical RTP is based on the game’s algorithms and probability models, not on actual player betting activity. It shows the percentage of money that a slot machine will pay back to players over time. Game developers use software and statistical methods to simulate millions of spins to estimate the RTP as accurately as possible before a game is released.

🧮 Here’s how the Theoretical RTP is calculated:

1. Game Design and Probability: The RTP comes from the game’s design. Each outcome in a slot game (like symbols lining up in a certain pattern) has a probability of occurring. The game developers calculate the likelihood of these outcomes using probability theory.
2. Payout Ratios: For each possible outcome, there’s a defined payout (how much the player wins). Developers calculate the expected payout for each outcome by multiplying the probability of the outcome by the payout amount associated with it.
3. The Sum of All Outcomes: The RTP is calculated by adding up the expected payouts of all possible outcomes. This sum represents the total amount of money that would theoretically be returned to players.
4. Percentage Calculation: Finally, the RTP percentage is obtained by dividing the total expected return to players by the total amount wagered, then multiplying by 100 to get a percentage.

Example:

Let’s consider a simple hypothetical slot game with three outcomes:

• Outcome A occurs with a probability of 0.1 (10%) and pays 5 times the bet.
• Outcome B occurs with a probability of 0.2 (20%) and pays 2 times the bet.
• Outcome C (losing outcome) occurs with a probability of 0.7 (70%) and pays 0 times the bet.

The RTP calculation would be:

• RTP from Outcome A = 0.1 (probability) × 5 (payout) = 0.5
• RTP from Outcome B = 0.2 × 2 = 0.4
• RTP from Outcome C = 0.7 × 0 = 0

Adding these together:

• Total RTP = 0.5 + 0.4 + 0 = 0.9 (This is the expected return per unit bet)

To find the RTP percentage:

• RTP % = (0.9 / 1) × 100 = 90%

The game has a theoretical RTP of 90%, which means that over a long period of time and many rounds of play, the game is expected to give back 90% of all wagered money to the players.

For example, if a slot game has an RTP of 90%, and a total of £10,000 is wagered over some time, the expected payout would be £9,000.

In online slots, these calculations are much more complex due to a larger number of possible outcomes and combinations. Based on this theoretical RTP, players can estimate how much a game will pay out over time.

Varying RTP Rates

You may come across a few online slot game reviews of games that have different RTP options. Most game providers such as Pragmatic Play have three different RTP options, while game provider Play’n GO has as many as five different RTP options.

This may be confusing for some bettors. Of course, everyone wants the best RTP slots, but what do these different versions of RTP rates mean? Since software game developers collaborate and partner up with online casinos, the casinos can choose which RTP they are going to opt for. This means that if a game has three RTP rates, such as 96%, 95% and 94%, and a casino chooses 94%, then that’s the payout percentage that will be used in that specific game at that specific online casino.

As players, there is no way of knowing which payout percentage you will benefit from. Since the payout percentages can vary considerably between one and the other, it is always best to play it cautiously and manage your bankroll properly.

What’s the Difference Between RTP and Payout?

The main difference between RTP and payout is that RTP gives you an average over time of how much a slot machine might return to all players, while payout tells you how much you can win in one game.

💸 Top 5 Best Payout Slots

Here are 5 online slots known for offering the highest RTP:

Casino Bonuses Available at Highest RTP Slots

Even if you have found the best RTP slots, you need to be mindful of any casino bonuses and promotions you are claiming. The right RTP can only take you so far, but if you are claiming casino bonuses that may be overly generous in size but come with bad terms and conditions, such as impossibly high wagering requirements, your odds of cashing out any winnings diminish considerably.

You also have to remember that the house edge, even if it is lower when it comes to high RTP online slot games, still plays an essential role in depleting the bankroll of the player. It is of the utmost importance then that all factors are taken into consideration, and simply not only opting for online slot games with a high payout percentage.

Shopping around for the best casino bonuses based on their fine print is crucial. Another key term to factor in when it comes to casino bonus terms is the eligibility of games. Some casino bonuses omit some if not all, types of high RTP slot games. You can generally see the entire details and list of games that are generally exempt from contributing to the wagering requirements on the terms and conditions page.
