Best Paying Slots – Which Online Slots Pay Out The Most?

Highest Payout Online Slots

Our guide to high-paying casino slots begins with ten game recommendations.

The following are some of the best RTPs slots we’ve ever seen, and these mini-slot reviews will help you pick the right one.

1️⃣ Goblin’s Cave – 99.32% RTP

Another gem of a game from Playtech, Goblin’s Cave, is one of the highest-paying real money slots ever built.

With an incredible RTP of 99.32%, this title has a house edge that’s even better than a casino game like roulette or baccarat. We’re not aware of any slots that offer higher rewards than this.

Released in 2012, Goblin’s Cave is obviously not the most graphically advanced or feature-rich slot. But its enduring popularity – high RTP aside – lies in its simplicity.

A well-balanced game with a medium volatility level, the action takes place on a minimalist grid of 3×3. And it’s possible to play at micro stakes, too, with wager limits ranging from just $0.01 to $5.

There are three distinct paylines, and you can hold symbols like traditional fruit machines of the past. The titular goblin is working away to the left of the screen to help you find various jewels, gems and gold coins.

But the lantern is the most valuable symbol of all, as it unlocks the bonus game. Here you can pick from 11 different treasure chests, each of which contains a random instant win prize worth up to 150x.

2️⃣ Ugga Bugga – 99.07% RTP

Created in 2013, this Playtech slot boasts an exotic jungle theme. A low volatility level that ensures consistent rewards helped win fans early on.

But it’s the incredibly high payout rate of 99.07% that’s most impressive about Ugga Bugga. Another unusual aspect of this quirky slot is the way it plays out.

It feels like a game of video poker at times, as you hold reels in a bid to hit combinations and earn prizes. These reels are set up in an unorthodox fashion, with ten separate sets of 3×1 symbols.

Play for the maximum payout of 1,000x from as little as $0.10 per spin all the way up to $250. Collecting the Wild Idol symbols should be your aim, as they unlock the game’s top prize.

But the different-coloured tiki masks are also valuable icons. The game lacks a bonus spins round, which is unthinkable in this era of innovative video slots. But this charming simplicity has only helped to cement Ugga Bugga’s image as a cult classic.

3️⃣ Mega Joker – 99.00% RTP

As NetEnt released Mega Joker way back in 2011, you might think the dated graphics and sounds would put players off.

But in truth, this only adds to the charm of a game that was designed to tap into a nostalgic vibe anyway. This slot looks exactly like the sort of old-school fruit machines found in bars and arcades back in the day.

Uncomplicated and lacking in high-tech, modern features, Mega Joker appeals to players of a certain age with its 3×3 grid and classic symbols. Line up grapes, lemons, cherries and bells to collect prizes.

Unlocking the Supermeter bonus feature allows you to play with a different set of 3×3 reels, offering more rewarding prizes.

The maximum payout is just 200x, and the betting limits are restrictive at $0.10 to $10. But that’s in line with how old-fashioned fruit machines used to be.

Some versions offer a progressive jackpot too, which seeds from $2,000. Aside from the sentimental aspect, the main reason players return to Mega Joker is quite clear. The RTP of 99.00% puts this classic game firmly among the best paying slots of all time.

4️⃣ Book of 99 – 99.00% RTP

Another popular Relax Gaming release, Book of 99, hit online casinos in May 2021.

At first glance, it looks like any of the many slots with an Ancient Egypt theme. There’s nothing especially unique about the concept, for example, which borrows heavily from Book of Ra and Book of Dead. Nor are the 10 paylines on offer or the 5×3 grid of reels especially innovative. However, once you scratch the surface, you realize that Book of 99 has a lot going for it.

You can play for as little as $0.10, but high rollers are also catered for, with an upper limit of $100 per spin. The maximum payout of 12,075x is very appealing, and the game’s Collection feature is interesting too. Collect 99 wild symbols to trigger the spins bonus round.

Alongside expanding symbols, you’ll find characters from Homer’s Odyssey, including a siren, a cyclops and Odysseus himself.

While the dramatic soundtrack adds an extra layer of intrigue and excitement, the pièce de résistance is undoubtedly the incredible Return To Player rate of 99.00%, which inspires this slot’s title.

5️⃣ 1429 Uncharted Seas – 98.50% RTP

This Thunderkick game has been around since April 2014, yet it continues to stand the test of time.

A beautifully designed slot set in the Age of Discovery, the theme is one of nautical exploration. And that’s neatly reflected by the game’s symbols, which resemble illustrations on an “olde-worlde” map.

Set sail for the voyage of a lifetime, discovering expanding wilds, accompanied by a dramatic soundtrack befitting of an epic adventure. Collect the compass symbols to gain up to 50 extra spins.

It’s not hard to see why 1429 Uncharted Seas remains so popular. The volatility level is very low, meaning a steady stream of smaller prizes appealing to casual or impatient players.

The slot features a classic 5×3 layout with straightforward rules. And the betting limits cover a wide range, starting from $0.10 and rising to $100.

The 670x maximum prize is not the largest, but then no slot is perfect. But what makes this game really stand out is the massive RTP of 98.50%. Few slots, whether online or land-based, can touch such a generous payout rate.

6️⃣ Money Cart – 98.00% RTP

Those of you familiar with Money Train by Relax Gaming might recognize elements of this particular game. That’s because it’s essentially a remake of that hugely popular slot, which features an enjoyable Hold & Win bonus game.

However, the Money Train base game made it tricky to access the rewarding and fun bonus feature.

In response to fan feedback, Relax Gaming came up with Money Cart. This spin-off retains the gunslinging Wild West theme, but offers a far more forgiving base game, played out on a 5×4 grid.

The trade-off for a more accessible Hold & Win bonus feature is a reduced maximum prize of 2,000x. But the RTP of 98.00% makes this game, released in December 2021, one of the highest-paying online slots around.

Big players will love the $500 maximum bet, but casual gamers are not priced out with a minimum wager of $0.10. The game’s high level of volatility might not be for everyone, though, with a hit frequency of just 12.50%.

7️⃣ Book of Dead – 96.21% RTP

A classic of the genre, Rich Wilde and the Book of Dead is arguably the most popular online slot ever produced. Aztec Idols was actually the first title to feature Play’n GO’s erstwhile adventurer.

But it was Book of Dead that really cemented Rich Wilde’s place as an all-time casino favourite.

With betting limits ranging from $0.10 to $50, Book of Dead adopts a standard 5×3 layout, a high level of volatility and ten paylines.

The maximum payout is 5,000x, and you’ll need to collect the Book of Dead scatter symbols for a shot at that. There’s also a fun gamble feature, allowing you to risk smaller prizes for up to 4x.

But much of the game’s popularity comes down to the high RTP rate. Book of Dead is just one title in an eight-strong series, not to mention the Cat Wilde spin-offs.

The franchise has proven so popular that almost every other slot game developer has created their own collection of titles with similar gameplay.

8️⃣ 777 Deluxe – 96.13% RTP

Released in April 2021, 777 Deluxe by Woohoo Games is an aesthetically pleasing game with a modern twist on retro slots.

It’s clearly inspired by old fruit machines, with symbols on the reels including cherries, horseshoes, bells and grapes. But a space-age soundtrack and some funky neon graphics provide a futuristic feel.

The payout mechanism is one area where 777 Deluxe differs from old-school slots. There are 10 paylines on the 5×3 grid of reels, but you aren’t just paid from left to right.

You can also match a winning symbol combination from right to left in what is often called “Both Ways Pay.”

There’s a lot to like about 777 Deluxe. It has a well-balanced volatility level, which appeals to a range of players. The minimum bet size of $0.20 is good for casual punters, while the $100 maximum suits higher rollers.

There’s a maximum payout of 5,000x up for grabs. Look out for the gold 777 symbols which are the key to unlocking that big prize.

9️⃣ Buffalo Blitz – 95.96% RTP

Playtech is one of the gambling industry’s true giants, with dozens of smash-hit slots in their catalogue. Released in July 2016, Buffalo Blitz is a highly volatile 6×4 reel game with a generous maximum win of 10,000x.

The 4,096 ways to win can expand to a maximum of 14,400 during an enthralling free spin round. It’s possible to collect 100 extra spins with unlimited retriggers, one of the best slot bonus features on the internet.

Players of all bankrolls can enjoy this title, with its North American wilderness theme, due to betting limits ranging from $0.40 to $200.

It is one of many online video slots designed around buffalo, and such games are always popular with players. But Buffalo Blitz has been so successful that it’s spawned several follow-up releases.

For instance, Buffalo Blitz Megaways builds on the original by incorporating four progressive jackpots, while Buffalo Blitz Live combines the popular slot with a live dealer game show. All games in the series feature symbols like raccoons, elk, bears and, of course, the mighty buffalo.

🔟 Mega Moolah – 88.12% RTP

This 5-reel slot, released by Games Global in 2006, was the first in a hugely successful series of progressive jackpot titles.

Although the RTP seems unimpressive at first glance, you need to factor the record-breaking cash prizes into the equation.

With every spin of the Mega Moolah reels, 5.30% of your stake is taken for the jackpot fund.

That’s why the RTP feels on the low side. But there are currently 13 (and counting) games feeding into the pool, which leads to some enormous payouts.

In April 2020, for instance, a Canadian player at JackpotCity won a staggering C$16,496,347.95 from Mega Moolah.

Don’t think it’s a one-off, either. Another player from Canada secured a C$20,059,287 payout in January 2019. A Belgian player set the world record for the largest slot payout in April 2021, earning a €19,430,723.60 prize.

The original Mega Moolah title has a pleasant African safari theme, with symbols depicting lions, rhinos, elephants and other wildlife. The rules are easy to pick up, but the prospect of massive wins makes this game so popular.

Payout Percentage of Online Slots Explained

It’s time we dig into some of the burning questions about slot payouts.

• How does the Return To Player percentage work?
• Is the payout rate linked to volatility?
• What is a good RTP value?

Keep reading to discover the answers to these questions and more.

What Is RTP (Return To Player) in Slots?

The Return To Player percentage is best explained like this. Imagine you play a game until the end of time.

How much of the money you put into the machine would you get back? That’s the RTP.

All slots use a Random Number Generator (RNG) to determine the outcome of a spin. So, on any given play, you could win a prize or nothing at all.

But over an infinite period of time, the money paid out will fall into line with the RTP amount.

The advertised RTP is independently verified by third-party software testing agencies like eCOGRA to ensure it’s real. The percentage effectively means that, in theory, if you spend $100 playing, you’ll receive that amount back. So 99% RTP means a $99 return on your $100 stake.

What Is The Average Payout In Most Slots?

You can’t really know the answer to this, as there are just too many games out there to perform a calculation.

It’s widely accepted among slot fans and iGaming software developers that a figure of 96.00% is the benchmark.

Anything above this and you’re comfortably into the high-paying territory, while values in excess of 98% are astronomical.

Are RTP and Volatility the Same?

No, but they are linked to the way in which a slot pays out.

Volatility, sometimes referred to as variance, dictates how frequently a game pays its prizes. But it has nothing to do with how much is paid out in total.

Let’s look at an example. Imagine spinning a slot ten times, $1 per play. You lose nine times, collecting a single prize of $9 from one spin. Overall, you spent $10 and won back $9, for a return of 90%.

Now consider a different game, where four of your ten $1 spins lose. Of the six winning spins, three pay $2 each and three pay $1, for a total return of $9.

See how both games returned 90% of your cash but in completely different ways? The game that featured many losing spins, with bigger than average prizes, is a highly volatile slot. Low volatility means more frequent rewards, which tend to be of a smaller size.

What Does A “Loose” Slot Mean?

The term “loose” in the slots world simply refers to a game that’s willing to pay out more than most.

If you’re playing a loose slot, your chances of winning a prize are greater than when playing a “tight” game.

How Does The House Edge Affect Slot Payout?

The House edge is a term more commonly associated with table games than slots, where we tend to talk about RTP.

It refers to the theoretical percentage a casino will keep from players. If you take the other side of the RTP equation, you can see the house edge.

For instance, if a slot has an RTP of 96.50%, the game retains a theoretical 3.50% profit for the casino. So the house edge is 3.50%.

Types of Slots With High Payouts

Most high payout online casino slots fall into one of three groups. Your standard “classic” slot, a jackpot slot or a progressive jackpot. Let’s now take a look at some examples.

Jackpot Slots

The difference between jackpot slots and their classic counterparts is the presence of a fixed jackpot. Often, there is more than one, with three or four jackpots of varying sizes.

Unlike regular slots, where you can win the top prize at any time, you’ll have to jump through certain hoops to secure a jackpot.

This usually involves collecting a certain number of special symbols. Popular jackpot slots include:

• Diamond King Jackpots (Spin Play)
• Rainbow Riches Pots of Gold (Barcrest)
• Playboy Gold Jackpots (Games Global)
• Hot Slot Mystery Jackpot Joker (Wazdan)
• Wheel Of Fortune Cash Link 2 (IGT)

Progressive Jackpots

Standard jackpot slots differ from progressives in the nature of their big prize. A progressive jackpot continues to grow, while fixed jackpots are always the same size.

Keep in mind that a percentage of your bets is taken when playing progressives to feed the prize pool.

That’s why the RTP numbers tend to be lower.

But the potential results can be jaw-dropping. Here are some of the best progressive jackpot slots:

• Mega Moolah (Games Global)
• Age of the Gods (Playtech)
• Mega Fortune (NetEnt)
• Aztec Millions (RTG)
• Jackpot Giant (Playtech)

Tips on Finding the Best High Payout Slot Games

We’ve already supplied you with a list of ten high-payout slot machines to enjoy.

But in addition, there are many other potential games to try; you just have to find them.

This next section reveals the key details to consider when seeking out high RTP slots.

What to Look For in Slots Besides High Payout Percentages

While the RTP is certainly something that casino players need to consider in a new slot, there’s much more to it. A good slot boasts many other features, including the following.

1. Special Game Symbols

All slots possess a paytable outlining the prizes gained for matching standard symbols. But the best titles also have unique icons that trigger special events.

Wilds can substitute for other symbols to create payouts.

Scatters activate extra games such as spins or gamble features. Others result in multipliers. Whatever it is, pick a slot that contains such symbols to ensure a more enjoyable experience.

2. Theme

There are dozens of different themes available these days, so you’re sure to find one that suits you.

History, mythology, and Halloween slots are always popular, as are nature, sport and science fiction. In recent years, we’ve seen a rise in branded slots.

These feature characters from major television series and movies, as well as musicians and famous celebrities. It’s always fun to play games associated with your personal hobbies.

3. Reels

The way a slot is laid out can play a big part in your enjoyment. You might prefer a simple, old-school 3×3 interface for the hit of nostalgia.

But these days, you’ll find huge playing grids with expanding reels and rows, such as Megways or Infinity Reels.

These can lead to hundreds of thousands of potential winning lines. Some slots do away with traditional elements altogether.

Both Ways Pay slots allow you to match symbols from either side of the grid, while the Cluster Pays mechanic doesn’t use paylines at all. Instead, you win prizes by matching clusters of touching symbols.

4. User-Friendly Mobile Play

Online casino customers are using their mobile devices more than ever to play slots while on the move.

Whether it’s a smartphone or a tablet device such as an iPad, the best casino slots are compatible with small-screen tech.

Top casinos offer slots via a mobile app, such as a native iPhone or Android app.

5. Software Providers

Take note of which developer is responsible for creating the slot, as it gives an indication as to what to expect.

An older company, such as Barcrest, is likely to produce retro games. Industry giants like Playtech and NetEnt make games that appeal to the masses.

While younger, smaller studios often push boundaries. Nolimit City, Play’n GO and Yggdrasil are award-winning providers known for their creativity.
