Best Payout Online Slots

We all understand online slots are meant to be fun, but the fact is some are designed to be more generous with their payouts than others. As such, we want to offer a helping hand so that you can choose the best slot machine to play, thus increasing your chances of walking away with a sizeable cash prize. Read on to discover all of our insights and tips!

What Are Slot Payout Percentages?

Before we dive into our list of highest paying online slots, we wanted to clarify what’s meant by a slot’s payout percentage. Essentially, it’s a broad term that incorporates several key elements that derive from a game’s mathematical model.

You’re likely aware each slot lists a Return to Player (RTP) percentage, which is something you can use to gauge your estimated returns when playing – more on this later. However, it’s not the only factor in play. If you want to delve further, you also need to consider each game’s hit frequency and variance.

Hit frequency refers to your chances of a particular outcome occurring. Whilst you rarely see this information within the game’s information panel, developers often reveal how often a win should theoretically occur, along with its size, as well as the likelihood of a bonus triggering. For example, a big win may drop in once every 300 or so spins, whilst a feature trigger once in every 200 – these are only hypothetical numbers though.

Variance, or volatility, however, refers to the overall gameplay. As you progress along the scale, from low to high variance slots, payouts often become less frequent but much more valuable. It’s a case of risk versus reward. If you prefer to keep your bankroll steady, low variance is the way to go; if you’d rather gamble for much larger payouts, high variance is the better option.

Ultimately then, there’s more than initially meets the eye when talking about slot payout percentages. As long as you consider the aforementioned factors though, and use them to make an informed decision, you can narrow down your search when looking for the best slot machine to play!

Best Payout Online Slot Machines

Now we’ve covered some key terms, it’s time to introduce our top 10 best-paying slots. 

This is based on the highest Return to Player rates, so it’s not necessarily a list of games that offer the greatest payouts, more so slots that award wins more frequently than others. That being said, there are still some fantastic cash prizes up for grabs!

How To Find The Payout Percentage For Online Slots

It’s all well and good for us to list our top 10 slots, but when you’re in the middle of a session you may suddenly decide to change games. Unfortunately, very few online casinos list their slot RTPs from within the lobby. So, the question that we’re faced with is how do you find out the payout percentage for any given online slot game?

Well, there are essentially three surefire methods to figure this out quickly:

  • Read our online slot reviews: Our primary concern is to deliver the most relevant information you’ll need. That’s why all of our reviews contain the RTP for each slot. Simply check in with us to discover any game’s payout percentage.
  • Check the in-game information panel: if you’ve already fired up your chosen slot, you can click the information panel to find the RTP. There may be several pages to scroll through, however, so be sure to read the text carefully.
  • Play in demo mode: If you’re more inclined to take a hands-on approach, many top online casinos allow you to test out slots in demo mode before you risk real money. Like we mentioned before though, remember to only use your findings as a guide. As soon as you switch to real play, the outcome could be completely different.

Return To Player (RTP) Explained

So, what is RTP in slots? The Return to Player rate is the percentage of all money wagered on an online slot that’s estimated to be paid back out. As a rule of thumb, the higher the RTP, the more often the slot is likely to pay out on average.

However, this is entirely theoretical and a slot’s actual RTP is rarely reflected during a typical session. The percentage is actually worked out over the course of millions, if not billions, of spins so you will see deviations during the short term. Of course, this can work in your favour; you can hit a huge payout within several spins and beat the odds. Always remember though that the opposite is also true; you can easily win less than you may expect.

For this reason, it’s always best to use a slot’s RTP as a rough indicator rather than a guarantee. You shouldn’t be surprised if your returns are some way off – at the end of the day if winning a set amount was a certainty, there’d be no excitement left. If you are fortunate enough to earn a profit then it is always recommended to play at fast payout casinos in order to get a hand on your cash ASAP.

The House Edge Explained

You’ve most likely figured out that if you flip the RTP percentage, you end up with the house edge. Although you’ll come across this term more often when playing popular table games such as blackjack and roulette, it does play a role in online slot games.

For example, let’s say you chose to play our #1 pick, Ugga Bugga. The listed RTP is 99.07%, which means there’s a 0.93% house edge. Now, this refers to the mathematical advantage the house has over you whenever you choose to play. So you’re ideally looking for slots with the highest RTP rates so that the house has less of an upper hand.

What Is Slot Variance / Volatility?

Although we touched upon this earlier, we can go into greater depth to outline how variance/volatility impacts slot gameplay. Think of it as a scale. At the one end, you’ve got low volatility slots and at the other, very high – extreme volatility slots.

Essentially, volatility gives an indication as to how the gameplay favours delivering payouts. Low volatility slots, like Starburst, traditionally generate wins relatively frequently. However, these payouts are often quite small in relation to your stake. So, if you’re looking to maintain your bankroll at a steady level, choosing slots at the lower end of the scale is a wise option.

On the other hand, high volatility slots favour infrequent payouts that hold a much greater value. Whilst cold streaks can occur on any game, there’s a greater likelihood of it happening here. There is a tradeoff, however. When the wins roll in, they’re typically much more valuable and there’s often a much greater maximum win up for grabs.

How To Find Loose Online Slot Machines

Before we go on to explain how to find loose online slot machines, it’s important to know what this term means. For starters, it isn’t an indication of an inherent flaw within a game that causes you to win more frequently. The terminology actually relates to slots that have mathematical models that are favourable to you, the player.

To put that into context, we’re talking about online slots with a high RTP rate, low volatility and a high hit frequency – a combination that results in regular rewarding payouts. Although a game’s RTP is easy enough to find, not all providers list a slot’s volatility and even fewer reveal their hit frequencies – some do, but not all. 

Unfortunately, there’s no master list of loose online slots. Ultimately, it’s a matter of doing a bit of research and forming a conclusion.

Progressive Jackpots

If we’re talking about the best slot games to win on, it’d be remiss of us not to mention progressive jackpot slots. These offer some of the largest potential payouts around, with some reaching into the millions.

Each time any player places a bet on a progressive slot, the jackpot increases by a portion of that wager. As you can imagine, with so many players trying to land a potentially life-changing win, prizes can grow very quickly. At the end of the day, it only takes one lucky spin for the jackpot to trigger, though we must say the chances of it doing so are minimal at best.

Nevertheless, if you want to put your luck to the test, check out our best progressives to see what you could win!
