"What is the best paying online casino?" - the question as old as time is still on the minds of players from every corner of the globe. So, our team decided to tackle this hot topic and help you in finding the casino that will be not only fair and licensed but also deliver great wins straight to your balance.

While we can’t make any promises, the fact remains that certain casinos are simply better than others. Let’s dive into the world of best paying online casinos together and see what the key factors are in choosing one!

Main Criteria for Choosing Best Paying Online Casino

There are players who like bonuses and some who get all hyped up about the latest payment method. However, when it comes to choosing one of the best paying online casinos to sign up with, one should also consider additional criteria. And trust us when we say, these might not be the first things that pop into your mind.

Low Wagering Requirements

As fun as bonuses are, you also want to have wagering requirements that can be reached on time. Therefore, look for deals with sensible bonus rules, rollover requirements up to x40, and long deadlines, so you can play stress-free.

In special instances, some wagering requirements can be as low as 20x – and there are even offers – like Paddy Power Games – which as no wagering requirements on its free spins bonus. These types of terms & conditions are a defining factor of the best payout online casinos. 

High-Paying Slot Games

With so many slot machines on the market, it is hard to keep track. Still, if you want to enjoy lucrative wins, you should focus on titles by providers that deliver high-paying slots even when playing at the best payline online casinos. Easier said than done! A little bird told us NoLimit City, Relax Gaming, BTG and ELK Studios have some of the best payout slots in the market. A couple of our top picks for the best paying online slot include:

San Quentin

In Nolimit City's San Quentin slot, players are presented with one of the biggest top wins we've ever seen in an online slot game. Players can win up to 150,000x their stake and features a wide range of bonuses that help to keep the wins coming.

Split wilds cause all symbols in a row to turn into additional symbols and increase the overall number of ways to win while extra positions can open up thanks to Enhancer Cells and xWays. There is also a free spins bonus with jumping wilds, and multipliers.

Money Train 3

Released in 2022, Money Train 3 features a max win of 100,000x. It is definitely one of the most generous games out there, with random respins and a hold & spin bonus that has some incredible winning potential.

During the hold & spin feature, players collect symbols with prize values attached to them - and, there are special modifiers that can increase the overall value of the board. For example, the Sniper doubles the value of symbols while the Absorber removes any regular symbols from the screen.

Millionaire Rush Megaclusters

Millionaire Rush Megaclusters from Big Time Gaming comes with a top prize of over 55,000x. It is a unique game whereby landing winning combinations causes symbols to break apart in order to increase the overall number of winning ways. It comes with a Mega Trail bonus where you can activate all sorts of amazing bonuses like multiplier wilds, transforming symbols and mega wilds.

Wide Selection of Progressive Jackpots

Nothing beats the allure of a great jackpot. After all, we are not talking about thousands but often millions in payouts! Look for big-name releases such as Mega Moolah, a four-tiered jackpot with the largest seeding at £1 million. Or perhaps try its sister series, WowPot!, with the biggest jackpot starting at £2 million!

Fast Payouts

After you win significant amounts, you’ll want to enjoy them ASAP. This is where the payment policies step in. Don’t settle for less, and rather spend extra time looking for casinos that grant both high and fast payouts.

Cashback Bonus

Ah, the cashback bonus! Something so many players overlook, as they get all smitten by hot welcome bonuses. Even so, a cashback deal is something that can help you maintain your focus (and a nice balance), even when things don’t go as planned. Make the most of it, and search for a casino operator with generous cashback and bonus terms that work well with your gaming style.

How Are Payouts Measured at Online Casinos?

UK online casinos provide a list of the RTPs of all of their slot games, but this isn't up to the casino operator. These are actually figures that come directly from the game developers.

There is one instance in which the casino has a say - for slots with variable RTPs. For example, some games from Quickspin can come with different payout percentages at different casinos - ranging from 94% to 96%. Casino operators can decide which version of the game to host.

This is why it's important to find out the exact RTP of the slot you're playing before you give it a spin for real money. This information is available in-game by clicking on the rules button, for example:

How Payouts Are Measured at Online Casinos

It is a common misconception that every online casino has its own payout percentage (RTP). This is actually not the case, as payout percentages are actually determined by game developers for their specific games.

So, a casino's RTP will only be as generous as the most generous slot game available on the site. For example, if you were at an online casino and played the slot Bloodsuckers, which has a payout percentage of 97%, that's what the RTP would be for your session. There is no specific figure attached to the casino itself that would override the game's RTP. 

What You Should Know About Bonuses at Online Casinos

After choosing an online casino to play at, it's time to look at the bonuses. While all casino promotions provide you with the opportunity to receive additional credits to play casino games and slots, they aren't all made equally. So, you should always check the terms and conditions to ensure that the bonus money on offer is really worth claiming:

  • Wagering Requirements: Even at the best paying online casinos, the wagering requirements might not be totally reasonable. 50x or more is considered very high while it's incredibly rare to find rollover requirements of 20x or less. So, be sure to look at bonuses where the wagering requirements fall someone on the lower end of the scale.
  • Expiry Dates: Make sure you have enough time to clear your bonuses. If your wagering requirements must be met within a couple of days, this might not be achievable so look for bonuses that take longer than a week to expiry.
  • Ongoing Offers: Some online casinos peak at their welcome bonus. So, if you like to claim promotions often, check out the casinos' Bonus page to ensure that there are plenty of ongoing bonuses to take advantage of.

Is There More to Finding a Best Paying Online Casino?

You might think all that is left to do is sign up and start gaming, but serious and responsible gamers know they are at the very beginning of their adventure called “finding the best-paying casino”.

Play Responsibly

One of our most important tips for playing slots games at online casinos is to keep things safe, responsible, and fun, we suggest you also find reviews written by users to see what they think of a certain operator. It is one of the best ways to get familiar with some of its weaknesses and perhaps even hostile or unfair practices.

Stay In Touch

Once you have found the casino of your choice, it would be wise to sign up for its newsletter and follow it on social media. By being more proactive, you might get the opportunity to keep up with the latest news and bonus offers. Who knows, maybe you’ll also get some extra deals via email!

Set Limits

In the end, don’t be foolish or get distracted by the possibility of a great payout. Bet only the amount you can afford, and make sure to utilize all the responsible gaming tools the casino company provides.

Set loss limits, deposit limits, and even take a break if you see your emotions have become overpowering. In the end, don’t forget, it’s all about having fun and not making serious money!
