It is estimated that there are over 20,000 slots available to play online. With so many on offer, knowing which one provides the best chance of winning a payout can be challenging. So, what are you supposed to look for in an online slot game?

One factor that determines this is the return to player (RTP). Below, we give the essential guide on the highest RTP slots and provide our selection of the best games.


Best Online Slots with Highest RTPGambling at online casinos is now more accepted and accessible than ever. But slot providers have had to do a lot of work to get to this point, making the industry safer and fairer. One way they have had to do this is by providing detailed documentation on the online slots they developed and how likely these games are to win — and the theoretical RTP is one of them.

The theoretical RTP, also known as the Return to Player, is a percentage value of the amount a player can expect to have given back to them should they play over a long period of time. The remaining amount is the value kept by the house as a profit. 

Imagine an online slot machine that has an average RTP of 95%. If a player spends €100 over a long time, they can expect to get €95 in winnings, with €5 going to the house. This rating helps show how likely a player is to win money from a game, so the highest RTP slots are theoretically the best payout slots one could play.

Of course, probability does play a factor in this. If you play one game and deposit €100, it is not a guarantee you will get €95 back. It is an average.

Imagine flipping a coin and counting the heads and tails results. It would not be a surprise if the coin came up tails three times in a row.

Yet if it came back with that result 100 times in a row, you would assume the coin is rigged. This is because it should average out with a 50/50 result over a long period.

Calculating slot RTP is a complex mathematical process. It takes numerous factors into account to get a reading of the percentage returned. It is also worth noting that it is one of many statistics worth considering when deciding if a casino game is worth playing.

When calculating the amount, a slot provider will divide the win by the turnover figures for a game. For example, if a game with a 95% slot RTP gets played for one month and accrues €10,000 in turnover, and pays out €9200 in wins, the calculation would be as follows:

9200/10,000 = 0.92

In this instance, the game would be well under the stated amount of 95% RTP. Luckily, these games are rigorously tested by manufacturers, online casinos, and independent bodies. Therefore, if you sign up to a legitimate slot site, you can assume these totals are pretty accurate.


Older slot machines that were found in Las Vegas casinos may not have displayed their slot RTP. Yet most online slots will be bound by law to display the slot RTP, depending on the country you play it in — this is especially true for UK online casinos, for instance. If you are playing at a legitimate online casino, then all games will have an easy-to-display rating.

You may have to dig into the small print at the bottom of the game screen to get this. Other online casinos may have information or an FAQ section that lists it.

If you can’t find the RTP in the game details of the online provider, then go to the manufacturer’s website. Type in the name of the game, and you should find all the information you need. In some cases, online affiliates will even have ranked online slots based on the best RTP ratings — simply search for high RTP slots!


Slots with high RTP rateMost regular players consider a good RTP to be around 96% or above. However, this should not be the only factor that determines the slot game you plan to play.

Volatility is a key factor that determines how often a high or low RTP slot pays out. If you don’t play regularly, this could be something to consider.

With a low-variance slot, you will win more often but with smaller payouts. This is best for conservative, low-risk players.

However, high-volatility video slots may be better for those who want more excitement. Payouts are more significant but less frequent. If you plan to play for a long time and do not care what type of game you play, then looking at the RTP becomes more important, as it is the amount you are likely to earn back.

If you want to play slots that were not mentioned in the above list. there are a few other high RTP slots found online; some even offering a progressive jackpot when triggering the bonus round! Here’s a list of the best RTP slots:

You will find that all of these are also packed with additional features, such as Free Spins and Wild symbols. Some games even offer fun mechanics that match the theme of the game, including a Supermeter bonus game, Road to Riches Bonus, Wild Joker symbols, Down the Rabbit Hole Free Spins, and Pots of Gold Bonus.

The house edge is the term given to describe the percentage leftover after RTP. It is the amount the gaming provider takes if a player deposits and plays a game for a long time.

For example, if a game has an RTP of 96%, then the house edge is 4%. It is the same way of describing more or less the same thing. That is how much goes back to the player and how much is kept as profit by the provider. 

That said, the house edge is generally a term used when describing table and card games like poker and roulette, as opposed to online casino games like slots.


A good RTP is always an attractive prospect, but another way casinos attract players to spin the reels is by offering dazzling casino bonus offers. These may include Deposit Bonus deals, Reload promos and even No Deposit bonus offers. These promotions can award anything from free spins, bonus money and even real cash, which is kind of like unlocking an additional bonus round.

Essentially, you should look at them as two separate entities and strike a balance. Look for games with the highest RTP (above 96%), then take a look at the ‘Promotions’ page. High RTP games are great overall, but bonus offers can give your gameplay an additional push and help you win even more payouts!

Keep in mind that many bonuses only allow you to access them if you satisfy the wagering requirements listed under the Terms and Conditions. Other terms may include expiration dates, jurisdictional limitations and a bonus win cap. Be sure to read through these before claiming anything.


Free spins do exactly as they imply. They allow a player to try out a slot machine without having to wager any of their own cash. This is great for players, as it allows them to spin for free while reaping the rewards in the process!

When playing high RTP slots, this becomes even more lucrative. As you have a higher chance of earning a payout, playing with free spins can be viewed as a slight increase in the RTP. Of course, the calculation would depend on how many free spins you earn.

Some free spins may have stipulations attached. These may include not being able to access bonus rounds or higher payouts. When choosing a game, how many free spins it gives out should be considered alongside the RTP.


While a degree of mathematics is involved in calculating the highest RTP slots, they are a statistic based on a probability and not a given. Therefore, all casino games, including slots, should be considered entertainment. You may be one of the lucky ones who win, or you may find your bankroll depleted with barely a payout, but entertainment is always guaranteed, especially when playing at LV BET.

We have a huge selection of high RTP slots waiting for you to play. From classics like Mega Joker and Starburst™ to Megaways™ games and branded slots. You can even try a progressive jackpot slot like Mega Moolah, offering FOUR progressive jackpots! Head to our site to see the whole range of titles and get started today.



Slot games with a high Return to Player (RTP) imply that you are more likely to win money. The percentage indicates the money that is returned to the player over a long period of time, with the remaining going to the house. However, there is no guarantee it will be profitable.

All slot games should be looked at as a way to entertain as opposed to make money. Probability plays a huge part in winning, and this is unpredictable.

You may play 100 games and win little or play once and hit the jackpot. There is no way of knowing how slot games will pay out, as they are completely random.


When you find a slot game with a high RTP, it means that the game pays out more money in winnings. Over some time, on average, you can expect to get the RTP returned to you from the money you put in. So if the RTP is 98%, around 98% of the money you put in will be returned to you.

However, you should not only look at RTP when choosing a game. Certain factors such as volatility, bonus rounds, and free spins should also be considered.


A high RTP does not necessarily mean that you will win more money. This is a rating showing an average of how much stake is returned to a player over a while.

This is more down to volatility, which shows how often a game pays out. Low-volatility slots pay out small amounts frequently. High-volatility shots pay out more but less often. Sometimes, high-volatility slots also have lower RTPs attached, despite the payout being more.


A low RTP is generally considered anything less than 96%. This means you can expect to be paid less in winnings than other slot games.


It is possible to play many of the highest RTP slots for free. Many games are available with free modes, including slots like Mega Joker, Legacy of Dead and Mega Moolah. However, you won’t win cash prizes.

Many online casinos also offer Welcome Bonuses, which include matched deposits and free spins. These let you play for free while also allowing you to win money. Just remember to read the Terms and Conditions before snatching any promo up.
