What is RTP

The Return to–Player ratio (or RTP) is the percentage of bets that a slot game will pay over an infinite life. A slot’s RTP value is expressed in percentage. For example, a 97% RTP game will pay out 97c for every EUR1 it receives.

The RTP is generally accepted as an indicator of how a slot will perform. However, it is only an average and has no intrinsic value. Players should not consider a high RTP to be an indicator of a return expected.

The RTP of a slot is calculated over a minimum number of spins. This means that the average won’t be accurate and will not affect your chances of winning any significant wins.

Top 10 Highest RTP Slots

You’ve found the best online slots with high RTP percentages. Below is a list of our top ten. However, remember that these slots may have the highest payout rates in practice, and RTP calculations are based on a lot of data. Any potential winnings that you make may be quite different from the average.

Book of 99 (99%).

Relax Gaming’s Book of 99 5×3 video slot has ten paylines and high volatility. The reels are framed in an ancient Greek temple filled with mythological heroes and heroines. To form wins, match two of the following figures from left to right. The free spins bonus will be activated if you land three or more book symbols. In this case, one of the three symbols will turn into the expanding wild. You’ll see a book stack appearing on the reels’ left. Collect 99, and you will be able to trigger the free spins bonus. This slot boasts a high RTP rate of 99%, which is the highest of all casino games.

Jackpot 6000 (98.9%).

Mega Joker is a similar design to Jackpot 6000. NetEnt knows how popular classic slots can be, especially for those with tight budgets. This medium volatility slot is one of the most accessible in the world, with bets starting at 10p and ending at PS2. Jackpot 6000 is again set in a brick-and-mortar casino. It uses two sets of reels. One of these can only be used in the super meter mode after a successful spin. There’s also a joker wild, which replaces other symbols.

Mega Joker (98.9%)

NetEnt created this high-volatility slot. It evokes the look of a mechanical machine and uses classic fruit symbols. Mega Joker has a low RTP of 99%, with only three reels and five lines. There are no bonus features, and there are very few bonus features. The base game is on the lower reels. If you place a maximum bet across all paylines and land a winning combination, you will have to decide. You have two options: cash in the amount or move to the higher reels and use the super meter mode. Payouts in the super meter will increase if you win the punt.

1429 Uncharted Seas (98.6%).

Thunderkick’s low-volatility 5×3 slot, 1429 Unchartered seas, let you sail into pre-Columbian waters. The game’s unique aesthetic is reflected in how the reels are drawn on a map and lit by candles on an old table. The reels are adorned with monstrous creatures, which adds to the eerie atmosphere. The scatter symbol in the game is the compass. It allows players to win free spins. Three, four and five will award ten spins each. Five will award you with 50. The sailing ship is a wild symbol. It expands to cover the reels and exposes the Kraken, which holds it in its tentacled grip.

Blood Suckers (98%)

Blood Suckers is the first of a series that NetEnt has created. It features Gothic-themed slots. The reels have 5×3 symbols, including wooden stakes and bibles, as well as bats and garlic. Players will receive ten extra spins for landing three or more scatters. During these spins, all wins will be tripled. Blood Suckers has a creepy bonus feature inside the burial chamber. Nightmarish vampires emerge from the chamber’s coffins. Could you get rid of them and collect your coins? Blood Suckers has 25 paylines and low volatility.

Marching Legions (98.1%)

Marching Legions, another product by Relax Gaming, is a unique title that stands out from all others on the list. The 243-payline, high-volatility slot features a soundtrack that fits Gladiator. It also features Lego-like movements and characterizes the Roman legions giving the game its name. This creates a unique gaming atmosphere. The bonus features of Marching Legions are numerous. One of the most notable is the marching-respins feature, activated when there is a full stack of soldiers on the reels. These soldiers also trigger the free spins bonus feature. If a stack moves beyond the game’s boundaries, players must complete one of five steps on the helmet at the top right corner. You can get extra spins if you complete all five steps.

Jokerizer (98%)

Jokerizer is set against a wild fairground. This aesthetic is in keeping with Yggdrasil’s crazy online casino slots. It is a high-volatility game with ten fixed lines. The five reels feature classic fruit symbols as well as lucky 7s. Jokerizer has a win-both-way payline structure. Combos pay out from left to right as well as right to left. Pay close attention to the joker symbols in the middle of the reels. If three of them land, you will receive a mystery win. The highest payout is 6,000 coins.

Starmania (97.9%)

Starmania is a low-volatility slot game that has an ethereal feel, much like NetEnt’s iconic title, Starburst. Starmania was created by Scientific Games and features an intergalactic background with reels full of dazzling jewels, stars, and other symbols. This game is different from Starburst because it offers bonus features. Landing two Bonus symbols will pay 20x your stake, four will give you 100x, and five will bring you a huge return of 200x. Three of these symbols will give you ten free spins. You can also reset your spins by hitting them again. This slot features ten paylines and a sci-fi soundtrack.

White Rabbit Megaways (97.8%).

In 2016, Big Time Gaming launched a new line of online slots. It featured a unique payline structure and was mechanized by Big Time Gaming. Megaways slots became immensely popular, and White Rabbit is an example. Lewis Carroll’s Alice in Wonderland inspires this five-reel, high-volatility slot. It offers a maximum of 248,832 chances to win, thanks to the Megaways structure. The reels feature Alice’s beloved companions: the Mad Hatter and Queen of Hearts, Tweedledum, Tweedledee, and Tweedledee, as well as the Cheshire Cat and Tweedledee, the evil twins. The sleeping caterpillar is a wild and multiplying symbol that enhances the reels. It can also be found in the Down the Rabbit Hole bonus spins round, which can award players with up 75 bonus spins.

Zeus Lightning: Power Reels (97.7%)

Red Tiger Gaming’s Zeus Lightning is our final recommendation. This high-volatility slot has 30 paylines and seven reels. The majesty and power of Zeus is the main theme in this game. When his stacked symbol appears, Zeus will randomly select a symbol to fill the reel. This will increase the payouts. A free spins bonus is also available, activated when there are three or more scatters. Players have two options when this happens: they can accept eight additional spins or take a bet on the Gambling Wheel. You’ll get four, twelve, or twenty spins if you choose to accept the latter.

What is Slot Volatility

High-payout slots sound great for bringing home big winnings. But it’s more complicated than that. RTP percentages are calculated by using infinite numbers of bets. This means they won’t always be the same as a typical play session.

The variance or volatility is a better indicator of how a particular slot will behave over time. Low variance slots payout low amounts with a high frequency. High-variance games pay out more often, but the payout value is generally higher than you would expect from a low-variance slot.

Progressive jackpot slots are the most popular type of high-variance slot. They offer players the chance to win a life-changing amount if they are lucky enough to be awarded the grand prize.

Medium volatility slots can be found that pay out more often than high-variance slots and have slightly higher values than low-variance slots.

Progressive Jackpots

Due to the huge cash prizes, Progressive jackpots are among the most popular slot variants. These jackpots grow with every spin, increasing in size and potential prize pots, before being paid out at extremely low frequency.

Optional side bets allow players to contribute to the jackpot, while the specific slot may only use a fraction. Progressive jackpots are not tied to any one game. This means that stakes from different slots can be combined into a single progressive jackpot. There is a very low chance of securing a payout because progressive jackpot games have high volatility.

Mobile Best Payout Slots

Online casino slots are a mainstay. You can enjoy the thrill of your favourite high-paying slot from anywhere in the world using your smartphone. Mobile gambling is growing at an incredible pace, with both Android and iOS users able to enjoy spinning reels from anywhere, anytime.

Game developers use the most recent developments in gaming technology, such as HTML5, to improve the performance of their chosen titles and make the experience more immersive.

A native casino app is the best way to enjoy mobile slots. These apps provide the best gaming experience and push notifications, so you don’t miss any bonus offers.

Native apps generally offer faster processing speeds than mobile-optimized sites. However, this will depend on your handset as well as the app. It can also be affected if the app is fully optimized for your handset and operating system.

Slot Bonuses

Bonuses have become a major part of online gambling. A good bonus can help you get started, whether playing low-variance games and getting small, regular payouts or trying to win big, one-off jackpots on high-variance titles.

Matched Deposits

The bonus is offered to new casino members by matching their first deposit up to EUR200. The bonus will double the amount you have already brought to the site. To withdraw, you will need to meet wagering requirements.

These are crucial, especially if your goal is to win big from a few wagers.

Get Free Spins

The perfect bonus for slot lovers is the free spins. These promotions are all about spinning the reels. A select number of free spins can be yours as a loyalty bonus or a welcome bonus. This means you have plenty of opportunities to enjoy your favourite slot titles while not paying anything.

Slot machines often offer free spins as prizes for winning combinations and success in bonus rounds. There will be wagering requirements, as with all bonuses. Before you sign up, make sure to understand them.

Contrary to matched deposit bonuses and free spins, wagering requirements for free spins are tied more to the winnings than the bonus’s monetary value.

No Deposit Bonus

You can claim no-deposit bonuses without having to pay anything. No-deposit bonuses are great for players who want to learn more about slot machines and sites.

However, no deposit funds are required. These bonus types may have high wagering requirements or other terms and conditions that must be met before any winnings can be claimed.

How to Stay Safe

While the best payout slots promise exciting gambling experiences, there is always a risk. Here are some things we recommend to help you stay safe online.

Do not spend more than you can afford to lose.

While high payout slots might seem like a great way to win big, RTP rates can only be an average of millions of hours played. They are a guideline to how the game will play out. It is important to be careful about how much you spend at a slot site. Also, don’t chase big wins in the hopes of a large payout.

You can set your limits.

Online casinos now allow you to set time and deposit limits. You can create restrictions to stop spending more time on one site or money than you want.

Self Exclusion

You might consider joining a self-exclusion program such as GAMSTOP if your online gambling has become more than a hobby. You can join such programs to ban yourself from accessing any licensed gambling websites. This can last as long as you want, up to five years.
