Revolution Casino review
100% UP TO€500 + 200 FREE SPINS
Code: Not required- Over 10,000 games
- User-friendly interface
- 24/7 live chat available
- Fast payouts
- Cashout limits of up to €40,000 monthly
The standard €10 minimum deposit makes this casino appealing to many categories of players. The fee-free payment options are another appealing factor of Revolution Casino. Its vast game collection of over 10,000 slots and 270 offers little to be desired for enthusiasts. The casino’s Curacao license is not among the most trusted licenses in the industry. The lack of a 24/7 live chat and mobile apps is an issue for some categories of players. Revolution has only 1 year of experience in the market, and its reputation is still weak.

Methodology for Top Online Slots Sites in Ireland
Step 1: Irish slots sites must have a valid license
We don’t even consider slots sites for our page unless they are:
- In conformity with the Irish Betting License issued by Revenue Commissioners
- Also hold additional certifications such as UKGC or MGA licenses
Another mandatory requirement is for their slots to be tested and certified by independent gaming auditors like: eCOGRA iTech Labs We want to ensure that crucial systems such as a game’s return to player percentage are accurate in the eyes of gaming technology experts after official analyses.
Step 2: We check the online slots sites’ RTP ourselves
The RTP of a slot casino represents the average of all cummulated RTPs of the games it hosts. Games are created by software providers with a specific rate which may change once there is a contract between a casino and the game developer.
We ensure that the rates are advantageous for your long-term play
Our team does this by personally checking and calculating the average RTP for each casino, so you can make your choice practically.
Step 3: We test slot volatility
The volatility of a slot determines whether you are likely to have large or small winnings, frequently or more rarely. This element drastically affects your betting and budget, so we ensure that a casino can offer you both:
- Low volatility slots: your winns are not much higher than your bet, but they happen regularly;
- High volatility: a winning combination may bring much more funds that you wagered, but it will take quite some time until this happens
Most games declare their volatility level in the settings section However, if we don’t have access to it, we will test the game for a period of a few weeks, using small both small and large bets, keeping a record of winning sums and frequency.
Step 4. We check the impact of a game’s paylines
Paylines, more commonly known as winning symbol combinations, varies widely, from 5, to hundreds. They may also work from end to end or be expanded by special features. While having more paylines looks like the likelihood of winning increases, many popular slots only have about 10 to 20 paylines.
Step 5. We analyse the unique features of the slot sites
- Multipliers: symbols that randomly multiply your results; they are often part of special features like Avalanche, or Bonus Spins;
- Wilds: symbols that, when appearing on the screen, expand your wager;
- Scatters: random symbols that can replace others to create paylines;
- Gamble: a special feature that can help you double your winnings or lose them all;
- Free spins feature: a feature that unlocks spins for which you don’t need to pay.
Step 6. We actually place bets
We test everything with real money bets. This means that our experience is the same as yours, which helps us accurately guide you every step of the way!
Step 7. We check the user experience on mobile & tablets
According to official statistics, a large majority of online slot games are available on mobile devices like personal phones and tablets. They are essentially Irish mobile phone online casinos that focus on slots. That’s why we test personally and extensively For the sake of responding accurately to your experience and removing any bias as per our advertiser disclosure, our testing must be thorough and layered:
- We employ different devices when testing online slots
- We look for device-specific glitches
- We test the games using different operating systems like iOS and Android.
Quick Breakdown
- We worked over 40 hours to test, and select the best online slots sites for our database.
- More than 20 hours were invested in analysing our results and structuring them into a useful, complete and factual page;

Our work never stops
