How does RTP in Online Slots Work?

The RTP percentage is not fixed and constantly changes while you play. There’s no way of knowing the current RTP percentage. Even casinos and game providers won’t know the current percentage, as RNG (Random Number Generator) software always ensures completely random results.

The percentage is calculated over thousands of spins, and the RTP we see is the average.

Since this is not a fixed percentage, you might notice when the RTP is higher or lower:

It’s important to remember that the percentage will shift again. It might be your next spin or 10 spins from now, but it will shift.

Auditors such as eCOGRA and iTechLabs track online slots and perform random tests to ensure fairness and accurate RTP percentages.

Low RTP vs. High RTP Slots – Is It Noticeable?

Comparing low RTP and high RTP slots will require some time to see the real difference since the percentages can shift; sometimes, the low RTP slot has a higher RTP, or the high RTP slot has a lower RTP at the time of playing.

Testing the same low and high RTP slots over time would reveal more accurate results. Let’s use a low RTP slot of 90% and compare it to one of the highest RTP slots at 99%. Playing both games for the same number of spins and similar bets, you’ll notice better profits from the higher RTP slot machines. Theoretically, you can expect a 9% higher return when using the slots in the example above.

Volatility vs. RTP

Volatility plays an important role in the way all online slots pay, including slot machines with the best odds. It determines how often you can expect winnings and the size of those payouts. To understand the basics of slot volatility, you only need to know about the three main categories, including low, medium, and high volatility.

Since volatility has an effect on the winnings you can expect, it’s important to know the differences when choosing the best payout online slots. If the volatility is high, the game won’t pay very often, but the winnings will be worth it. This is also the case when playing slot machines in land-based casinos.

Tips for Playing High RTP Slots

Our expert tips will help you make the most of your experience playing online.

1. Find the Right Slots for You

While we generally recommend going with the slots with the highest RTP, you should still find something that you enjoy playing. If the first game on the list doesn’t seem like the right fit, consider the ones after it. The differences between the best high RTP slots are quite small, so it is more important to choose something fun and entertaining.

2. Play at the Best High RTP Slots Sites

Picking the right casino is just as important as knowing which slot machines pay the best. By going with the top sites for high RTP slots featured in this guide, you don’t just benefit from great games but also have access to secure banking that lets you manage your funds easily. You will be able to withdraw your profits without hassle.

3. Use Casino Bonuses and Read the Terms

In general, online casino bonuses are great for playing slots since they provide loads of extra funds. However, some bonuses can exclude the highest RTP online slots because they are so advantageous for the player. This means that you may not be able to use the bonus funds on these games. Check the terms and conditions for excluded slots before claiming the deals.

4. Use the Demo Mode to Practice

Many of the slots with the highest RTP have various bonus features and rounds. It is important to know how these work before betting real money. We recommend reading the game info and playing in demo mode to practice with free credits. This also allows you to see how the RTP actually goes during a short session.

5. Stay Within Budget

Just because the game has a higher payout rate than most other slots, it doesn’t mean that you are sure to win. Don’t bet more than usual because you are playing slots with the highest RTP. Instead, stay within budget and keep the bets small. This will allow you to play for more and thus benefit from the payouts over longer sessions.

Responsible Gambling

While playing high RTP slot machines is fun, you should always ensure that you do not wager money that you cannot afford to lose. The return to player percentage does not offer any guarantees, so while you can use it to determine which high RTP slot games to play, you should not expect to win high or frequent payouts.

Practice responsible gambling to keep playing slots and having a fun experience. All our featured casinos provide helpful resources and voluntary limits that you can use to keep your gambling activity under control. If you require further assistance, you should contact a casino’s customer care team or speak to a professional organization.

Best Payout Slots Casino

If you’re looking for the best RTP slots combined with large bonuses, secure banking, and fast withdrawals, Wild Casino is the best platform in 2025. It offers a large library of games to choose from, and this includes many of the best RTP slots covered in this guide.

Unfortunately, Wild Casino doesn’t have a way to filter slots by RTP, so you will have to look up the preferred games in the search bar. Luckily, all of the options are provided by trusted developers, and the overall payout rates are great.
