Playing online slots comes with a series of immediate and long-term advantages that are not easily ignored. First and foremost, playing online is safe and hustle-free. Licencing an online casino is a titanic work and literally costs an arm and a leg – I won’t go into details – and an operator won’t risk throwing almost €300,000 out the window just to let you play a faulty game. That makes the games perfectly balanced with a very optimised game mechanic. Second, keeping your private information safely stored on servers behind state-of-the-art encryption is a must for these reputable online slot casinos. Finally, the perks that come with enjoying online slots can be translated to an enhanced gaming experience due to all the bonuses you’re entitled to, once you open an account – a feature specific to the online gambling community.

Tested & Inspected Slot Games at Licenced Casinos

The United Kingdom Gambling Commission, the Malta Gambling Authority and the Gibraltar Gambling Commission are a few of the main licencing bodies that are in charge of making sure an online casino is compliant and operates according to the law. Besides the operator licence, the operator’s slots portfolio is individually tested and inspected, so each game is a testament to fairness and accurate mechanics. A physical casino slot machine might be tampered with – it’s been proven to happen – yet such a thing would be impossible in the slots casinos we’ve tested. World-class auditors independently test all existing slots in millions of rounds in order to check for such interference, and let me tell you, the consequences would be dire for any misdeeds. The result is that playing online slots at the best Irish casinos is actually the safest way to play!

Casino Slots with the Highest Payout

Who wouldn’t want to maximise the time spent in front of their favourite slot? And before spinning the magic reels, ask yourselves this: would you rather play at a slot casino you’ve never heard of, or would you rather make the most of each spin at a high-payout money maker? Folks, the secret of online slot machines is this: you must know how to pick them and where to find them. Luckily for you, we’ll put you on the right path by showing you some high-paying slots and why spinning their reels will put a smile on your face!

In the comparison above, we want to highlight the fact that the return-to-player percentage (RTP) is not the same thing as high volatility. The RTP is merely an average of how much the online slot will pay over a period of time, while the volatility is directly associated with the risk element. To make things easier, a high-volatility slot is a risky slot machine that pays a breathtaking sum of money over long-term gaming sessions, while a low-volatility or low-variance slot will offer lots of small to medium wins in a shorter time frame. Pairing either an online slot that has low volatility (to make the most of your gaming budget) or an online slot that has high volatility (if you’re an aggressive, risk-taking gambler) with a high RTP is a good strategy that works well at online casino slots.

Best Online Slots with Jackpots

The record for an incredible payday was set on 6 October 2015 when Mr. Jon K. from the UK was enjoying a session of Mega Moolah. While spinning its reels and forming winning combinations across its 25 paylines, Jon triggered the jackpot worth €17,879,645. When a lucky player wins any of the jackpot, the prize is reset and a small part of each and every bet goes towards progressively refilling the ‘pot’ that keeps all the money for the next winner.

The best online slots wouldn’t be as much fun without a dedicated bonus package, a free bet, a special offer or even the bonus spins that are awarded as additional perks. By choosing the right offer, you can make the most of every spin and have loads of fun doing it. The bonuses for casino slots come in many forms and size. For a better understanding, we’ll cover them right here.

The Welcome Bonus is aimed at new players who are just opening an account. It usually consists of 100% of your first deposit, with a limit of up to €100 or €200, depending on the operator. A minimum deposit is needed in order to qualify for the offer. The extra money you receive from the operator can be put to good use by doubling your play time, for example. There are a few things to consider, though: the bonus has a validity period, a wagering requirement and a minimum deposit to qualify for the welcome package

Testing Online Slots and Playing for Free

Practice does make perfect, and because the certified slot casinos in Ireland are focused on their customers’ needs, we’re given the opportunity to test the slots we love for free. Known as demo mode, this unique feature allows you to play freely at zero risk to get used to the game’s mechanics and rules. As soon as you’re comfortable with the way the game is played and have mastered its rules, feel free to opt in for some of the free play bonuses.

Strategies for Playing Online Casino Slots

It’s crucial to know that you can strategise to improve your winning chances. But before we talk strategy, we must discuss discipline – managing your bankroll and controlling your emotions are the best things you can do; otherwise, gaming stops being fun. But if you’re ready to win, our team of experts has some top tips for you:

Choose the online slots with the highest payouts and always make sure you register with a certified casino – check our list of recommendations.

Test the slot in demo mode to further understand its game mechanics and special features. What triggers the bonus? How many paylines are we talking about? With these questions answered, you’ll be able to determine the slot’s variance.

Depending on the volatility of the slot, set the wagers for a minimum to medium amount and use all the paylines – in theory, more paylines translates to more winning combinations.

Use the free spins as often as you can because if you don’t, you’re just leaving money on the table.
