Top 10 Slots with 99% RTP

Most players just pick a game based on the theme, graphics or bonus features. But one of the factors to consider when searching for your next online game is its RTP.

RTP is the percentage of all bets that a slot is programmed to pay back to players over time. Most slots sit around 94% to 96%, meaning the casino keeps a small percentage of all wagers. But some rare slots have an RTP of 99%․ This means casinos return almost all the money wagered back to players over the long run. For example, Alchemist Bonanza has an RTP of 96%, which means, the game will give players $96 for every $100 wagered on average.

Now, this doesn’t mean you’ll win 99% of the time or always get your money back after playing. Slots are still random and anything can happen in a single session. But choosing a high RTP game gives players a better chance of holding onto bankroll and stretching playtime.

The tricky part is that 99% RTP slots are hard to find – they’re not as common as lower RTP games. But we’ve done the work for you. Below, we’ve listed the top 10 best paying slots with 99% RTP, along with their key details, like volatility, release date and what makes them worth playing. If you want to get the best value from your spins, these are the games you’ll want to check out.

Understanding RTP in Slot Games

Now, let’s go a bit deeper into what RTP actually means and why it matters when you play slots.

The RTP (Return to Player) percentage in slot machines is calculated using the following method:

• Divide the total amount of money the machine pays out in winnings by the total amount players bet, then multiply the result by 100.
• If players bet $200 on a slot machine and it pays out $190, the calculation is: $190 ÷ $200 = 0.95.
• Then, 0.95 × 100 = 95%.

This shows the slot machine has an RTP of 95%. In other words, for every $100 players bet, they can expect to get back $95 on average over time.

It’s also important to understand that RTP isn’t the only factor that affects how a slot plays. Volatility (sometimes called variance) determines how often and how much a game pays out. A slot with high RTP and high volatility can go for long stretches without wins, but when it does pay, the rewards can be big. On the other hand, low-volatility slots give smaller but more frequent payouts, making them better for players who prefer consistent returns.

Another thing to keep in mind is that not all versions of a slot have the same RTP. Some game developers allow casinos to adjust RTP settings, meaning the same game could be 99% RTP at one casino but 95% at another. That’s why checking the RTP before you start playing is always a smart move.

So why does RTP matter? Because the higher the RTP, the better your long-term chances of getting more value from your bets. While it won’t change the randomness of a single spin, choosing a game with a higher RTP helps you play for longer and get the most out of your bankroll.

How to Find Slots With Highest Return

Finding high RTP slots isn’t always straightforward, as not all casinos openly display RTP information. Some provide this data in the game description, while others don’t mention it at all. If you want to ensure you’re playing a slot with the best possible return, here are some reliable ways to check:

Check the Game’s Info Section

Most slot games include an information or paytable section, where details about paylines, special features, and RTP are listed. This is usually the most direct way to verify a game’s RTP before you start playing.

Look at the Game Provider’s Website

Many well-known providers, such as NetEnt, Playtech, Relax Gaming, and Barcrest, list RTP values for their games on their official websites. If a casino does not provide the RTP, checking directly with the developer ensures accuracy.

Read Independent Slot Reviews

There are many gambling review sites that publish detailed RTP breakdowns for popular slots. These reviews often compare different versions of the same game, as some casinos offer lower RTP settings.

Contact Casino Support

If you can’t find RTP information anywhere, you can always ask the casino’s customer support. A transparent and reputable casino should be able to provide RTP details for any game they offer. If they are unwilling to share this information, it may be a red flag.

Play at Licensed and Regulated Casinos

Casinos that are regulated by bodies like the UK Gambling Commission (UKGC), Malta Gaming Authority (MGA), or Swedish Gambling Authority (SGA) must follow strict transparency rules, including providing fair RTP values. Choosing a licensed casino ensures that games are running at the correct RTP settings.

Watch for Adjustable RTP Slots

Some providers allow casinos to adjust RTP settings for certain slots. This means a game might be available at 94%, 96%, or 99% RTP, depending on where you play. Before playing, always double-check that the casino is offering the highest RTP version of the slot.

By following these steps, you can be sure that you’re always playing at the highest possible RTP, giving yourself the best long-term value for your wagers.

Strategies for Playing High RTP Slots

Even though high RTP slots offer better potential returns over time, they are still random games of chance. We have created a mini guide to help you get most of your sessions.

1. Manage Your Bankroll Carefully

Even with a 99% RTP slot, wins and losses are unpredictable. It’s essential to set a budget before playing and stick to it. A good approach is to never wager more than 1-2% of your total bankroll per spin, which helps you extend your playtime and reduce risk.

2. Understand Volatility

A slot’s RTP tells you how much it pays back over time, but volatility determines how those payouts are distributed. If you prefer more frequent but smaller wins, go for a low-volatility high RTP slot. If you’re comfortable with bigger risks for larger payouts, then a high-volatility high RTP slot might be a better fit.

3. Take Advantage of Casino Bonuses

Many casinos offer free spins, cashback, or deposit bonuses that can be used on high RTP slots. These promotions can stretch your bankroll and give you more chances to win without extra spending. However, always read the bonus terms — some casinos exclude high RTP slots from wagering contributions.

4. Play at Licensed Casinos

A high RTP means nothing if the casino is unreliable. Always choose licensed online casinos to ensure fair play and to avoid altered RTP settings.

5. Test the Game in Demo Mode First

Most online casinos let you play slots for free in demo mode before betting real money. This is an excellent way to test the game’s mechanics, volatility, and hit frequency before committing real funds.

6. Stick to Fixed RTP Versions

If a slot comes with multiple RTP settings (e.g., 94%, 96%, 99%), always choose a casino that offers the highest RTP version. If a casino is unclear about RTP settings, it’s best to look elsewhere.

7. Know When to Stop

Winning is great, but knowing when to cash out is just as important. If you’ve hit a significant win, consider withdrawing some of your winnings rather than continuing to play. Likewise, if you’ve reached your loss limit, it’s best to step away rather than chase losses.

8. Monitor RTP Performance Over Time

Although RTP is calculated over millions of spins, real-world player data can sometimes show trends. If a game seems to be going through an extended cold streak, consider switching to another high RTP slot with a more favorable hit frequency.

By applying these strategies, you can maximize your playtime, manage your risk, and improve your overall experience while playing high RTP slots. While no strategy can change the random nature of slots, making smart choices gives you the best possible chance of getting more value from your sessions.
