1. Mega Joker Slot

RTP: 99.00%

Mega Joker is the most popular high RTP slot ever created. It’s also one of NetEnt’s most popular games, slightly below Starburst in the popularity charts.

The title features a classic setup with a particular twist: there are two sets of reels, with the top reels being the most profitable due to the higher payouts yet easily accessible even when gambling with low stakes.

Mega Joker also comes with a local progressive jackpot that any player can win. If you play the game in a popular casino, you’ll notice that the jackpot easily reaches the €10,000 mark quite often.

Not only is this game popular among video slot fans, but it also stands out due to it being one of the best RTP slot games with a progressive jackpot ever created!

2. Jokerizer Slot

RTP: 98.00%

Jokerizer is an Yggdrasil slot game that combines the essence of classic slots with its fruit symbols and the magic of video slots with a 5-reel setup.

Gameplay is quite simple, but landing a joker symbol on reels 2, 3, and 4 allows you to trigger a MysteryWin based on how much cash you’ve bet.

The game only boasts 10 paylines, but its Mystery Win feature is complemented with an exclusive wild feature called “Jokerizer Mode”, which allows you to pay money from your wins to buy a re-trigger.

During re-trigger rounds, you only need two wilds to trigger the Mystery Win feature!

3. White Rabbit Megaways Slot

RTP: 97.77%

White Rabbit Megaways is the best high RTP Megaways slot that we’ve ever played. The theme, clearly inspired by Alice in Wonderland, makes it a one-of-a-kind game and one of Big Time Gaming’s finest slots.

However, its max win of 17,429x the amount of your bet is the real reason why the game is as popular as it is.

The game comes with a medium to high level of volatility, as free spin rounds will have you enjoying the game’s largest profits.

Expanding symbols combined with free spin rounds are your key to success when playing White Rabbit Megaways.

4. Blood Suckers Megaways Slot

RTP: 97.66%

The base Blood Suckers game is one of the industry’s most popular slots, having been launched by NetEnt well over a decade ago.

Its subsidiary studio, Red Tiger Gaming, launched a “2.0” version of the game in 2023 featuring a max win of 20,521x the amount of your bet and a low betting range of €0.1 to €4. In our experience, it’s much more fun than the original title.

This version of the game features cascading reels and massive potential for chaining win after win, which makes it an extremely entertaining title and one that you should try as it’s the newest game features on this list.

5. Blazing Bull Slot

RTP: 97.42%

A relatively high hit frequency, combined with a formidable RTP, make this animal-themed slot game into a very solid option to choose if you’re keen to play high RTP slot games.

Although a unique theme is not what makes this game shine, the title’s bonus rounds with free spins and multipliers are sure to keep players on the edge of their seats.

Blazing Bull is all about the Silver and Gold games, which are the special rounds we’re talking about. You can trigger rounds with wins of up to 50x plus 15 free spins, turning a standard bet into a win of up to 2,667 times the amount of your stake.

6. Leprechaun Riches Slot

RTP: 97.35%

Leprechaun Riches is one of the best RTP slot games to play on mobile devices, as it was created by mobile-game specialist PG Soft. It features a max win of 100,000x the amount of your stake, and 46,566 ways to win.

The fun, fast-paced slot game allows players to earn up to €2,000,000 in rewards thanks to the game’s incredible multipliers.

It’s one of the fixed-jackpot slot games with the highest potential payout, a feature that you’ll surely love when considering its way-above-average RTP rate.

7. Big Bad Wolf Slot

RTP: 97.29%

Quickspin’s take on the Three Little Pigs story will have you collecting pig symbols and building their little houses to create massive chained wins.

The Tumbling Reels feature will allow you to create many winning combinations within a single spin (or fall) of all symbols.

Besides, the Pig symbols will start turning into wilds as you chain win after win. Every third re-spin, a new pig symbol will become a wild.

Should you manage seven respins in a row, profits are almost a given unless you’re really unlucky with the tumbling symbols!

8. Treasure Island Slot

RTP: 97.07%

Relieve the adventures of the classic Treasure Island TV show with this high RTP, low volatility slot game that features standard video slot gameplay.

If you like video slots without too many features, this wild-packed slot game is right what you’re looking for.

Big wins come when you manage to chain wilds with one another, and the title’s maximum bet of €100 makes it one of the best high RTP slots for high rollers that you can play in 2024.

Wilds and scatters are quite common in this slot, which directly influences its high return rate and low volatility.

9. Steam Tower Slot

RTP: 97.04%

NetEnt has delighted us with Steam Tower, one of our team’s favorite Steampunk slots (just behind the Microgaming masterpiece Fortunium Gold).

The game’s high RTP puts it among the highest-paying casino slots in the industry, and its adventure theme will see you climb a tower in your quest to save the princess and collect as many riches along the way as you can.

The higher you go up the tower, the better multipliers you’ll be getting per spin. Scatters and wilds play a crucial role in the Steam Tower slot’s profitability – you’ll need to collect as many as you can to reach the game’s max win of 1,633x the amount of your stake during free spin rounds.

Mermaid Millions has a slightly above-average RTP, but it’s earned a spot in our list thanks to it being one of the best low volatility games that we’ve ever played.

If you’re keen for a relaxed gaming experience, this is the slot you’ll want to try out.

You can play with as little as €0.15 per spin, and it’s hit frequency of 34.15% makes it likely that you’ll experience wins once every 3 spins.

What is a High RTP Slot

RTP, a term that stands for “Return to Player”, is a common gambling term used to refer to a percentage that represents the amount of money that the casino expects to pay out from a specific game. A high RTP slot is a game where the return rate is above the industry’s average, generally rivalling the expected return rate of the highest-paying casino games like blackjack and poker.

The average online slot has an RTP of 96%. All of the games that we’ve listed on this guide come with larger return rates!

Blackjack games have an RTP of around 99%, whilst poker games have RTP rates that oscillate between 97.50% and 99%

Check out this quick guide to RTP created by the Casino Wizard team:

• High RTP: 97:00%+
• Medium RTP: 95.00% to 96.99%
• Low RTP: 94.99% or less

How to Tell the RTP of a Casino Game

There are many ways in which you can tell the return rate of a casino slot game. The easiest ways to do it are as follows:

• Open the “Game information” tab when playing the game. In most cases, this will allow you to see the current RTP version of the game that you’re playing;
• Go to the developer’s page. Most software providers list the RTP rate of their games within their own websites, and tell users all available options that are offered to casinos;
• Read it on The Casino Wizard. We do the hard work for you and list the RTP of all popular games in game reviews such as this one!

Key Features of High RTP Slot Machines

As you’ll discover testing the games that we’ve listed on this article, the world of the best RTP slots is widely varied. Games with all sorts of themes, mechanics, and attributes are there to be found, but there are some key features that stand out and make these games different from the rest:

• Bonus Features: Many games offer high return rates thanks to the ability for players to chain win after win, combining exclusive features like Tumbling Reels with multipliers, bonus rounds, free spins, special wilds, scatters, and much more.
• Varied Betting Range: High RTP slots, like any other casino game, can be played with small sums of money. Many games come with minimum bets of just €0.10! But you need to keep in mind that some games only offer high return rates when wagering over the minimum stake.
• Volatility Variations: High RTP slots are not tied to a certain level of volatility. You’ll come across many games, with some even letting you tweak the volatility settings depending on how you wager your cash!

Progressive Jackpot Games: RTP Explained

Fans of online slots will almost instantly notice that the best jackpot slots, such as Mega Moolah or Book of Atem, come with lower return rates than fixed-jackpot slots like Starburst or Book of Dead (if you like the game, you can get 50 free spins for Book of Dead). This is because a part of the wagers placed by the player will go towards building up the progressive jackpot.

Read our Starburst slot review to learn more about the legendary online slot.

So, if the casino and the developer generally share a profit of 4% in a 96% slot game, a progressive jackpot game with an RTP of 94%, such as Age of the Gods, would send that extra 2% towards the progressive jackpot.

These are estimates only, of course, but you get the point. That’s the reason why progressive jackpot games always have lower return rates than your classic video slot titles.

Why Play Slots with the Highest RTP?

High RTP slot games tend to be the best casino games to play in the industry – especially to those pragmatic players that prefer odds over anything else. Statistically speaking, these games are as good as it gets to minimize the loss of money.

Players who like to take risks could play high RTP slots with high volatility. These games tend to have large fixed jackpots and, since their RTP rates are quite above average anyway, players will have a good chance of keeping their bankroll at a good level while still qualifying to earn good rewards.

Low volatility games with a high RTP rate, on the other hand, are more likely to help you keep a stable balance but you’ll depend on streaks of good results to increase your profits.

When to Play Medium and Low RTP Slots

In most cases, it’s a good idea to play online slot games (and other casino games) that come with high return rates. These are going to give you the biggest statistical possibility of making a profit in the short term, as well as putting in your favor the odds of losing less money than the average player.

However, there are two scenarios where we recommend our readers play low and medium volatility games even if they have access to high RTP titles. These are:

• When you’re chasing a progressive jackpot. Jackpot hunters and high rollers could do well playing medium or low volatility slot games if they’re competing for the prizes that await playing games like WOWPot slots or Mega Moolah
• When you’re trying to fulfill the wagering requirements of a bonus. Take into consideration the stake weights of your bonuses when playing games to fulfill their rollover. If high RTP slots come with a 10% stake weight, you’ll be better off playing low RTP games.

The Relationship Between Volatility and RTP

Contrary to what most players think, volatility and RTP are not directly related. Volatility is more related to hit frequency, as it determines how often a winning combination is likely to pop-up when playing slots.

Amateurs often think that a game with high RTP should also have a hit frequency and therefore low volatility, but that’s not the case.

You can have a highly volatile game, with winning rounds rarely coming ever 6 or more spins, but with each of these rounds paying a lot of money on average.

Let’s paint a picture with two common scenarios:

• Let’s imagine that you’re spending €2 per spin, and you spin the reels 10 times to no avail: you would’ve lost €20. Then, a couple of winning rounds come in, allowing you to win €9 and €15 respectively. That’s generally how a lucky set of rounds of a highly volatile, high-RTP slot game goes!
• On the contrary, a game where you win frequently but each win pays out almost the same or slightly more than your bet is much more common in games with low volatility and high RTP.

Slots RTP and Casino Bonuses: What You Should Know

One of the reasons as to why it’s important to read the rules of a casino bonus is to check which games are banned from bonus play. You’ll notice that, in most cases, online casino slots with high RTP rates are not permitted to be played with an active bonus.

The reasoning of casinos is simple: if you’re given a bonus with a wagering requirement of 35x and you spend it on games with a return rate of 98% or more, then there’s a large probability that the majority of players would walk away with a profit.

Casino Wizard Tip

Go to the "Bonus Terms" section of your chosen casino before you claim one of its bonuses!

This is the same reason why you’ll see that stakes placed on table games contribute less than 20% towards the fulfillment of wagering requirements. Otherwise, bonuses would be assurances of free money!

Best RTP Slot Facts & Must-Knows

Sometimes, return rates aren’t as straightforward as they may seem. Should you need further clarification or tips that’ll help you gain a better understanding of game return rates, we encourage you to read out list of RTP facts:

• The RTP of a casino slot game is calculated over time. The more rounds you play, the more likely you are to get closer to the RTP of a game;
• Hit frequency isn’t tied to RTP, just like volatility;
• It’s important to check the real RTP of progressive jackpot games. Some pages list the RTP including jackpot payouts. For example, some pages say that the Mega Moolah RTP is 96%, whilst it’s actually 88.12% if you exclude the jackpot.
• Players should always check the RTP of a game when you first play it in an online casino. Software providers often develop multiple versions of the same game, with RTPs that generally vary from 88% to 99%. Casino providers can choose which version of the game to host.
• It’s impossible to alter the RTP of a casino slot by changing the way you play or your bet size.
• The Ugga Bugga slot used to be one of the highest RTP slots to grace the online gaming industry, but it's no longer available.
