Frequently Asked Questions
Here we answer the most common questions about online slots and casino games to help you make informed choices.
-
Are online slots legal and safe to play?
Yes, online slots are legal and safe, provided you choose a licensed and regulated online casino. In Ireland, this means looking for a site with a license from the Malta Gaming Authority (MGA) or the UK Gambling Commission (UKGC). This ensures fairness of casino games and player protection.
-
How is gambling regulated in Ireland in 2025?
Since the introduction of the Gambling Regulation Bill 2023, the industry is in a transitional period. The Gambling Regulatory Authority of Ireland (GRAI) will soon replace the current licensing regime. All casinos on our list currently hold valid international licenses (MGA, UKGC) that are legally accepted in Ireland and will be subject to the new authority’s regulations.
-
How do I choose a trustworthy slot site?
Choosing a trustworthy slot site requires careful consideration. Look for a valid license, check for positive casino review ratings and read reviews from independent sites like ours. We prioritize sites with a proven track record for fast withdrawals, excellent customer support, and a high-quality range of games and bonuses.
-
What are wagering requirements and how do they work?
Wagering requirements (also known as ‘rollover’) are a multiplier that dictates how many times you must play through a bonus amount before you can withdraw any winnings. For example, if you receive a €10 bonus with a 20x wagering requirement, you must wager a total of €200 (€10 x 20) before you can cash out. It’s crucial to read the T&Cs apply to every bonus offer. They are one of the most important terms and conditions to understand.
-
Can I really win real money on online slots?
Yes, you can absolutely win real money playing online slots. All of the casino games on licensed slot sites use a Random Number Generator (RNG), which ensures a fair win rate. While success depends on luck, players win real money every day, from small payouts to massive progressive jackpots. You can find detailed review on which slots payout best on our site.
-
What is the fastest payment method for withdrawals?
Based on our testing, e-wallets like PayPal, Skrill, and Neteller are typically the fastest payment method for withdrawals, often offering instant options or just a few speed hours after the casino has processed your request. Bank transfers and card payments are usually slower, taking up to 3-5 business days. The payout speed is one of our key review criteria.
-
Do I need to download software to play slots?
No, you don’t. The vast majority of online casino games are ‘no download’ platforms. You can play directly in your web browser, on both desktop and mobile devices. Some slot sites also offer dedicated apps for an even smoother mobile experience, but they are not required to play.
-
How do casino bonuses work?
A casino with a good bonus offer will often match your first deposit with a percentage of bonus funds, up to a certain amount. For example, a 100% max bonus up to €200. They also offer free spins on specific slot games as part of the package. All bonuses are subject to terms and conditions and a min deposit to activate.
-
What does RTP (Return to Player) mean?
RTP, or Return to Player, is a theoretical percentage that indicates the amount of money a slot game is expected to pay back to players over a very long period of the time. For example, a slot with a 96% RTP is expected to return €96 for every €100 wagered. It’s one of the most important factors for players to consider as it gives you an idea of a game’s long-term profitability. This is a crucial factor in our review process.
-
Which slot sites have the best mobile apps?
Based on our hands-on testing and review ratings, sites like 888 Casino and Bet365 Casino offer the best slot apps. They are fully optimized for all mobile devices, with fast loading times and a full range of slots and games and a great live casino experience available. We always check a casino with a good mobile platform.
-
Do I pay tax on online gambling winnings in Ireland?
No, you do not pay tax on gambling winnings in Ireland. The Irish Revenue Commissioners do not classify gambling winnings (including online casino, sports betting, or lotteries) as taxable income. However, you are still responsible for gambling within your means and reporting any business-level activity.
