6 Best Payout Casinos in Ireland Compared

Top Paying Slot Games in Ireland

Here are the top 15 best paying slot games in Ireland ranked by their advertised RTP (Return to Player) percentage.

Most online slots in Ireland typically have RTPs ranging from 92% to 96%, but all of these best paying slots feature an RTP of 97% or higher:

The RTP percentage is a factor to consider when selecting which online slots to play. This provides an estimate of the expected returns over an extended period of time.

Theoretically, for every €1 staked on an online slot game with a 98% RTP, €0.98 is returned.

The RTP % of a slot machine is not guaranteed, it's a calculated long-term average of the amount paid out divided by the amount staked on that game. It does not indicate the outcome of any individual game session.

But by choosing the best paying online slots with higher RTPs, you are likely to get more value for your money over the long run and maximise your bankroll.

However, some players prefer online slots with lower RTPs and higher 'max wins' or the allure of massive progressive jackpots.

For example, despite Mega Moolah's RTP of 88.12%, it has awarded several huge jackpots to online slot players, like the €17,879,645.29 million won by Jonathan Heywood at Betway in 2015.

Highest Paying Casino Games

Casinos are not just about online slots. In fact, the best paying online casinos also get their stellar reputation through casino games. Whether it is roulette, blackjack, poker, or another game, you can expect quality payouts from the following games:

How to Find the Best Payout Casino in Ireland

Irish players have loads of choices when it comes to selecting an online casino. So, picking a casino site for you can easily become overwhelming. That is where our dedicated team of industry experts can help.

Our expert casino team is comprised of casino specialists covering games, cybersecurity, finance, website design, and more. We look for the best paying casino venues, so you don’t have to! Importantly, our search for the best casino operators is never over. We constantly scour the gambling industry to find the latest and greatest sites.

That is why it is worth bookmarking this page and checking back to see the best new online casinos, best game releases, and more.

Check Our Casino Reviews

A lot of work goes into our casino reviews. Therefore, you will find the most comprehensive casino reviews around on this page. Our team uses a strict, multi-step review process that covers every aspect of an online casino. No stone is left unturned, allowing us to give you a complete overview of a casino site, including the following essential criteria:

• Security: Our number one priority is the safety of our readers. You will never see us recommending a casino that does not hold a licence with a recognised global authority (such as the UK Gambling Commission). Furthermore, we highlight casino operators that use the latest cybersecurity technology to protect customer data.
• Fairness: Online casinos work with game providers that ensure the software is fair. Usually, this means allowing independent testing of games to assess if the results are random chance. In other words, all outcomes are determined by luck and not an unfair influence from the casino.
• Payments: We expect the casinos we recommend to provide flexible casino payment options from leading providers. Furthermore, those financial platforms should be completely secure, so you can deposit and withdraw casino funds with complete confidence.
• Games: At the heart of the casino experience is the games. Whether you love slots, table games, or the authenticity of live casino software, the sites you see on this page provide the ultimate flexibility. While we like to see as many games as possible, our reviews will also focus on the quality as well as the quantity.
• Bonuses: Casino bonuses are a handy way to boost your bankroll, whether you are registering for a casino or an existing player. The online casinos that actually pay out value their customers and will run lucrative welcome bonuses and ongoing promotions.
• Support: Problems occur, and mistakes happen, but it is essential to solve issues efficiently when they arise. We put casinos to the test by contacting customer support through all channels, including live chat, email, and FAQ sections.

While each of the criteria above is important, it is the combination of all these factors that determine the overall quality of an online casino. For our reviews, we are passionate about taking an honest approach. So, when we look at a casino, we will highlight its flaws as much as we praise its qualities.

Check the Game RTPs

When we seek the best casino for payouts, RTPs play a significant role in our assessments. The return-to-player (RTP) percentage shows how much a casino game will payout on average. So, if a slot has an RTP of 97%, it will return 97c (€0.97) on average for every €1 spent on a game. Yet, this does not mean every €1 you wager will return 97c each spin, as the average is from a sample of hundreds of thousands of rounds.

Sometimes you can beat the RTP (and make a profit), and other times you will lose to it (the casino makes a profit). Even so, the RTP is a good indicator of how often a game may pay out. While we discuss the RTP in our reviews of casinos and slots, you can also find this information for yourself. Game providers list the RTP of their software, while casino operators will often put the overall payout rate of the casino on their site.

Check the Terms and Conditions

Finding a casino’s RTP on the site itself highlights why it is important to read the terms and conditions when registering for an account. Understanding the T&Cs will help you become familiar with the requirements and limitations. Also, this is especially important with bonuses, which often have wagering requirements, game eligibility quotas, and restrictions on payment methods.

We make sure to highlight essential T&Cs in our reviews, but you can also easily find this information at your chosen online casino.

Tips on How You Can Win Real Money at Casinos 

Our in-depth reviews are always on hand to guide you through the casino industry. You can also take a look through the casinos on this page to find best real money sites with the best payout rates. However, we think it is essential to pass on our knowledge and help our readers find the best casino games (and hopefully win money on them).

Our experts have put together the following list of top tips that may help you win real money at the casinos we recommend. Importantly, it is worth remembering that there are no guarantees of success when gambling at online casinos. That’s why we prefer to view online gambling as a form of entertainment.

So, the tips below won’t give you guaranteed success, but they may help you feel more confident in your ability and gamble more responsibly:

1. Choose the Highest Paying Games and Slots

As revealed on this page, there are tons of games available with high payout rates. You may have a better chance of success by picking slots and casino games with a high RTP. Remember, the RTP is over a vast sample, so it is not a guarantee you will win “X” amount. Still, choosing a game with an RTP may slightly tilt the odds of success in your favour.

2. Play at the Best Payout Casinos

By selecting one of the best paying online casinos we recommend, you can boost your chances of winning. Each casino site we recommend provides a wide selection of games, including slots with a high RTP. Yet, you can also gamble with confidence, knowing our highlighted sites offer the strictest security standards.

3. Take Advantage of Casino Bonuses

Casino bonuses are a relatively straightforward way to boost your bankroll, giving you a little more to use on casino games. There are tons of bonuses you can claim, including deposit matches, free spins, no deposit offers, and more. Bonuses can be lucrative, but choosing promos with generous T&Cs is crucial. So, always check the wagering requirement and other limitations before committing to a bonus.

4. Play New Online Slots and Games

The iGaming software industry is constantly evolving and never standing still. Dozens of new games become available each month. While we love older games, it is always worth exploring new online slots and other casino games. You may find a hidden gem, a modern classic, or just a new game that has an excellent payout rate.

5. Remember to Play Responsibly

Remember, gambling is meant to be fun and should be seen as a form of entertainment. Playing responsibly will allow you to keep having fun and avoid the pitfalls of problem gambling. If you feel you are struggling, online casinos have increasingly excellent resources. You can contact trained staff, set limits for deposits, bets, and time on the casino, and access charitable foundations to seek advice and help.
