How We Rate The Best Payout Slots Online

These are the key characteristics that our team analyzes to identify and rank the best payout online slots.

Return to Player Percentage

To be considered for our top list, games must have one of the best online slots payout percentages. Blood Suckers and Wild Cupid, for example, have RTPs of 98%, which is significantly higher than the majority of other slot machines. We carefully analyze the RTP of each online slot to make sure it aligns with market averages. While some outliers like Blood Suckers are good to have, the average online slot RTP is 96%, and the minimum we take into consideration is 95%. The Return to Player percentage is only one factor which determines slot payouts, which is why many of the best payout online slots have an RTP of around 96%, but boast multipliers of up to 200,000x your stake.

Hit Frequency

In addition to checking which slot machines payout the most, our team looks at the average hit frequency of these games. White Rabbit Megaways and Quest to the West have hit frequencies of 27.6% and 27.4% respectively, which means that you can expect a win every three or four spins. The hit frequency is analyzed through meticulous first-hand testing over thousands of spins, and the data is pulled by our team of experts in order to provide an objective evaluation. Typically, high volatility slots have a lower hit frequency, but they tend to pay out in bigger amounts, whereas low volatility slots have a higher hit frequency that pays in lesser amounts. 

Bonus Features

While most players look for the highest payout online slots as they’re looking for frequent or sizable payouts, we also consider the entertainment factor. This increases significantly when there are multiple bonus rounds, such as with the Secrets of Atlantis or Cash Compass slots. Of course, bonus features aren’t merely entertainment features, as they significantly boost an online slot’s payout rate. Free spins rounds, click to win bonus rounds, and different types of online slot bonus rounds are carefully analyzed by our team and evaluated how they blend into the entire slot machine’s payout rate. 

Max Win

While there is no correlation between the payout percentages and max win of slot machines, players are naturally attracted to games that offer the potential for sizable prizes. By playing Greedy Goblins and Book of Dead, for example, you can win payouts that are worth thousands of times your base bet. Many Megaways slots offer maximum payouts of up to 200,000x your bet, which is why they’re so popular on the market right now. We heavily consider the slot’s maximum potential when selecting the highest payout slot machines. 

Available in the US

While there are many high RTP slots, they are not all accessible in the US. You can play the featured games with real money at several listed offshore online casinos. While some of these sites, including Mega Dice, may require a VPN, they are all able to welcome players from the USA.

Mobile Accessibility

The mobile gambling market in the US is steadily increasing and is expected to reach almost $155 billion by 2030. It is, therefore, a priority for software providers to create mobile-friendly games. You can play Ocean Treasure and all other featured payout slots from anywhere without needing to download an app thanks to HTML5 or similar mobile technologies.

What Are Slot Payout Percentages?

Payout percentages are created by mathematical calculations following extensive testing. These percentages are officially calculated by independent test labs after they have run a slot for thousands of rounds.

The Return to Player i.e. payout percentage indicates how much you can expect to win when you play a specific slot. A 90% RTP game, for example, is likely to pay out $90 for every $100 that you wager on it. This value, however, is only indicative and based on thousands of rounds. 

Casino players are unlikely to play enough rounds to come close to proving the RTP. By playing a few rounds, the outcome of the game is much more unpredictable, and while this may result in higher losses, it can also result in jackpot wins or high-value payouts.

While the average slot machine RTP is 95%, top payout slot machines have RTPs of between 96% and 98%. Very few slots have RTPs higher than 98%, but other online casino games, including video poker and Crash games, commonly feature high payout percentages.

What is Slot Volatility?

Slot volatility, also known as slot variance, determines how frequently and how big the slot will pay out – in simple terms. 

A high volatility slot pays out less frequently, in larger amounts, whereas a low volatility slot pays out more frequently in lesser amounts.

A combination of high RTP high volatility slots is totally possible, which may be confusing to new users. In the same vein, low volatility, low RTP slots also exist. In general, however, high volatility slots have a median RTP of 96%, whereas low volatility slots have an RTP of over 97%.

Blood Suckers is one of the best low volatility slots, and it has an RTP of over 98%, whereas White Rabbit Megaways for example, is a high variance Megaways slot with an RTP of over 96%.

Before playing any highest payout slot machine, it’s important to analyze the volatility rates, because they determine the maximum payout you can achieve and the general payout size. If you’re looking for big wins, high volatility slot machines are always a good idea.

We recommend playing low variance slots for wagering a bonus, playing it safe, or when operating with a limited budget.

How to Find Payout Percentage on Slot Machines

If you’re playing slot machines that payout real money and want to find out their RTPs, you can view the individual paytables as the figure is normally published there. You can also try to calculate the percentage yourself, however, you would need to play thousands of rounds to reach an accurate result.

To calculate a slot’s RTP, you need to keep track of the total value of wagers placed and the total value of payouts won. Divide the payouts by the wagers and multiply by 100 to get to the payout percentage.

Wild Casino High RTP Slot Selection

Types of Real Money Slots at The Best Online Casinos

Online casinos and online slot games go hand in hand. Slots are the most popular  online casino game type in online gaming, and most online casino sites offer 1,000+ slot machines for you to explore. 

They are split into various categories, which signify the game mechanics on which these slot machines are based. Moreover, each slot has a separate theme, set of bonus features, RTP, and volatility levels. 

The available slot types have recently increased significantly thanks to innovations from leading software providers, such as Big Time Gaming. That’s why we provide a concise guide to the types of slot machines available at leading online casino sites. 

Classic Slots – 3-Reeled Slot Machines


These are simple, 3-reeled slot machines that used to be all the rage back in the day. Now, they are yesterday’s news, but still, some players prefer them for the nostalgia factor. The payouts are decent, too, and some 3-reel classic slot machines like Mega Joker have a high RTP of 99%. That’s why classic slots have stood the test of time despite the dated graphics and super limited game mechanics. 

New classic slots are rarely produced, but many old releases by Microgaming, NetEnt and Playtech are still circulating. Some examples include Mega Joker, Break da Bank, and Break da Bank Again. 

Classic slot machines have high volatility. This means they won’t reward you frequently, which is to be expected, considering they only have 3 reels and just as many symbols as many video slots. Prepare a sizable bankroll if you’re set on playing one of these titles. We generally advise against playing them; there are better options in every conceivable aspect. 

Video Slots – 5-Reeled Standard Modern Slot Machines


Video slots are what people refer to when they say “online slot game” nowadays. It’s the standard for a modern slot machine, featuring 5 reels, 25 paylines, several bonus features, free spins, Wilds and Scatters. 

The Wilds have an exceptional impact on the slot machine payouts, substituting for any other symbol on the reels. The Scatter symbols also impact the payout percentages, triggering the slot’s bonus round, which typically awards free spins. 

These online casino games are known for superb graphics, animations, looping soundtracks, and quirky sound effects. They’re fun, engaging, and pay out well. The feature set extends beyond the basic symbols, featuring Expanding Wilds, Stacked Wilds, Rolling Reels, Avalanche Reels, and so forth. Some of the best examples include Starburst by NetEnt, Gonzo’s Quest, Immortal Romance, Thunderstruck II, and Cash Bandits. 

You can play a high, low, or medium volatility game, depending on the video slot. This dictates how often, and how much will a slot machine pay. There are 150+ gaming suppliers designing video slots today. A new title is released almost daily, and the average online casino has thousands of video slots on display.

The best real money online casinos feature video slots by providers such as NetEnt, Big Time Gaming, Red Tiger, Microgaming, Betsoft, Rival, Real Time Gaming, and many more. 

When playing online slot games, make sure to check the RTP (payout percentages) and volatility to ensure it’s the right game for you. The minimum payout percentage considered acceptable by modern standards is 95%. 

Megaways Slots – up to 117,649 Paylines (Ways to Win)


Megaways revolutionized online slot machines at online casinos, offering slot machines with dynamic reels and a shifting number of paylines on each spin, presenting up to 117,649 ways to win.

This opens up the opportunity for massive multipliers up to 250,000x your stake. This means a potential win of $62,500 from a single $0,25 spin. This winning potential almost reaches that of progressive jackpots. As such, Megaways slots are the highest paying slot machines.

Online casinos feature dozens of Megaways slots, and the best online casino sites powered by Pragmatic Play and partnered who’ve licensed the Megaways licensed feature the likes of Bonanza Megaways, The Dog House Megaways, and White Rabbit Megaways.

Megapays Slots – up to 117,649 Paylines Progressive Jackpots

Megapays slots expand upon Megaways slot machines and extend the portfolio of online casino games through this progressive jackpot Megaways variant that improves uopn the standard video slot machine jackpot structure.

These slots feature rewarding base games, at least two bonus features, including free spins, and Wilds and Scatter symbols. 

These are high volatility slot machines, and the average RTP for Megapays slots ranges between 95% and 97%. Beyond Wilds and Scatters, these slot machines can feature Cascading Reels and Multipliers, which is why many online casino players love them.

Some popular examples of these slot machines available at the best online casinos include Bonanza Megapays and Who Wants to Be a Millionaire Megaways, both developed by Big Time Gaming.

Big Time Gaming remains the sole provider of Megapays slots. However, the formula of expanding and dynamic reels, high volatility, high payout potential through multipliers, and progressive jackpots will likely stay on for years to come. 

Megaquads Slots – For The Biggest Slot Machine Enthusiasts 

The Megaquads slot machine is in fact four individual slot machines in one. The payout percentage for this game varies between 96% and 97%, and not many real money casinos offer this game type as of yet, considering it’s still a fresh game type release by Big Time Gaming.

Once you boot up a Megaquads slot machine, you’ll see four individual sets of reels. Spin the reels and you’ll see all four sets spin and potentially form winning combinations. Where it gets interesting is when each individual slot machine starts combining its payouts and multipliers with the rest. This opens up massive payout potential through regular bets. 

Megaquads slots also feature standard slot machine features, such as bonus rounds, free spins, Wilds, Scatters, Expanding Wilds, Avalanche Reels, and so forth.

How much these slot machines pay is difficult to estimate. Their volatility is as high as it gets, even more than Megaways and Megapays. Perhaps that’s why they’re yet to take off with players. However, their formula and payout percentage are outstanding.

Top examples of Megaquads slot machines available at US online casinos include Slot Vegas Megaquads. This slot offers an exceptional up to 16,777,216 ways to win. 

Hold and Win Slots – Assume Control of The Slot Machine


Hold and Win slots are famous for their high payout potential, engaging bonus features such as free spins, and the potential for massive wins. 

The key mechanic behind Hold and Win slots is the player-controlled re-spin feature. Namely, on each Hold & Win slot machine, you can decide to freeze i.e. lock certain symbols in place and trigger a re-spin, increasing your chances of forming a winning combination and a strong multiplier.

These games are high volatility, and the average payout percentages of Hold and Win slot machines at online casinos is 94% to 96%. There are some exceptions in terms of volatility as some designers such as Wazdan have created medium volatility Hold & Win slot machines and supplied certain online casino sites, though these titles are rare.

The best examples of popular Hold and Win slot machines include Playson’s “Hold and Win”, and Booongo’s “Dragon Pearls: Hold and Win”. 

Daily Drops & Wins Slot Machines – Jackpot Potential With Every Spin

Nowadays, it’s the norm for the best online casinos to feature Pragmatic Play’s Drops & Wins on the homepage, with jackpot prizes averaging $2,000,000. They are simply that popular, overtaking the throne of popularity at online casino sites offering these casino games. 

The premise behind this slot machine is simple. In partnerships with online casinos, Pragmatic Play selects a certain number of slots eligible for Drops and Wins. Players who play these slots have a chance to earn drops, and each drop holds a certain cash prize. The total amount of daily drop prizes varies each day, but it’s usually massive. 

The average payout percentages of Drops and Wins slot machines are between 95% and 96%, and the volatility ranges between medium and high. This means that while the payout percentage is not above average, resulting in a below-average hit frequency, the payout potential of these slots is incredibly high. 

A few of the most popular slot games using the Drops and Wins mechanic include Wolf Gold and Sweet Bonanza, both released by Pragmatic Play. These are headliners at the best real money online casinos, especially crypto sites like TG Casino. 

Bonus Buy Slots – Instant Access to The Bonus Features


Bonus Buy slots have been making the rounds in casino games libraries for years now, and their success has led them to becoming banned in some regions like the UK. This online slot has a minimum payout percentage of 94%, but the average is 97%.

These are high paying slot machines but with a heavy dose of risk involved. You can buy the bonus directly without waiting for the Scatters to land on your reels, potentially wasting hundreds of spins in the process, but the price is hefty, often $200+ – depending on stake size.

Depending on how these slot machines pay, the bonus buy feature can be worth it, but if the free spins round proves ineffective, then you may be left empty-handed.

These high paying slot machines are best enjoyed with a large bankroll, ideally combined with a valuable casino bonus. That way, you can take full advantage of its payout percentages.

The best software providers of Bonus Buy slots include Relax Gaming, NetEnt, and Pragmatic Play. As expected, these are high volatility slots with a varied payout percentage, but they are some of the highest paying slot machines on the market next to Megaways.

Progressive Jackpot Slots – Win Millions from a Single Spin

progressive jackpots slots

Progressive jackpot slots don’t have impressive payout percentages, but these slot machines pay $10,000,000+ from a single spin. The odds of that happening are equal to winning a lottery ticket, but some jackpot hunters enjoy these slots and the thrill they bring compared to different casino games.

Mega Moolah by Microgaming and Divine Fortune by NetEnt are the highest paying slot machines in terms of progressive jackpot payouts to date, but not by payout percentage. Nowadays, many providers have released dozens of progressive jackpots, with varying prize pools from a couple of thousand dollars to millions. 

Typically, each jackpot slot’s payout percentage is affected by the fact that a small portion of each bet goes towards the jack pot. This results in a lower RTP and a less rewarding base game compared to regular slot machines. That’s why we don’t recommend playing progressive jackpots, but we’re sure some of the big winners out there would disagree! 

Top Progressive Jackpot Payouts in Online Casino History

These are the lucky few that made it out with life-changing jackpot sums, some of which originated from a minimum wager of $0,25, such as Jon Heywood when he broke the Mega Moolah record at Betway Casino.
