Read Genuine, Unbiased Reviews for the Best Online Casinos in Ireland

It is important to realize that not every online casino in Ireland that opens its virtual doors to Irish players is actually worth signing up with. Many of them are fake online casinos that are designed with the sole purpose of stealing your money. Once you sign up with these sharks, you will never see your money again! This is why it is important to always find real reviews that have been written by experts and are totally unbiased. In other words, Irish players looking to invest in an online casino or two would do well to read our expert reviews.

Our team of highly experienced online gamblers knows exactly what to look for when reviewing prospects for the Irish market. We sort out the chaff from the wheat and guide you to the best, most trusted, high-performance online casinos in Ireland, making your experience worthwhile and fun every time you play for real money sitting in front of a desktop at home or on a mobile device, chilling in a park, for example.

Online gambling is basically playing video games for money-winning purposes and the final result is a matter of luck. The nature of the game of chance (another name for gambling games) is determined entirely by a random number-generating algorithm at the back end of the games' software. It can be an instant play or you might need to download an easy-to-use casino app for a better gaming experience.

Consequently, an online casino is a web-based or mobile operator that allows players to have access to gambling games that are running on the software supplier servers and enables deposits and withdrawals (usually by means of third-party apps). Since Irish players have to rely on their luck first, casino game developers must reveal the chances of winning with every game they launch, denoting in particular:

  • The overall percentages of the return in slots online and how it is spread in regular game mode or free bonus game
  • The possibility of any win in online spin games
  • The likelihood of wins in a row and others.

Best Irish Online casinos are audited and licensed by specific governmental and independent authorities: the Return to Player rate is audited by eCOGRA, for example, among others. If you're looking for stronger and safer online casino licenses - look for Malta Gaming Authority, UK Gambling Commission or Gibraltar Regulatory Authority to play for real money.

The licensors act as a guarantor that the online casinos are fair and comply with the rules of fair play, control players' financial transfers and adhere to their T&Cs. CasinoSlots Ireland plays its own part in this complex gaming industry, by analyzing, evaluating, and rating numerous Irish online casinos and their offers. We've developed our own criteria to measure the efficiency of internet casinos in Ireland from 1 to 100 through the following categories:

  • Trustworthiness (License strength, Responsible gambling policy features, Complaints resolution process, Alternative Dispute Resolution bodies available
  • Casino welcome bonus package (total value to the player, the availability of deposit matchup, bonus free spins, deposit bonus wagering requirement, etc.)
  • Online casino games available (including the variety of casino game providers, composition of the lobby, demo plays, and availability of other games)
  • Banking options (what deposit/withdrawal methods are available, Banking transfer / Visa / MasterCard / Debit card/e-wallets payout speed, pending time, withdrawal limits, etc.)
  • Players engagement

Welcome bonuses

There's nothing better than getting some free money on your deposit at the very beginning of your online casino journey. You might have probably wondered what the welcome casino bonus offer is. In real life, you have to work harder to get some extra money in your paycheck. Online casinos in Ireland instead will give you, as a new customer, nice 1st min deposit offers that will be added to your bonus account once you register and make a deposit. iGaming operators boast various attractive promotions that come in different sizes and shapes (every new casino tends to break through with something special). Even if you make a min deposit of EUR10, there's nothing wrong with getting some freebie bonus cash (usually in a form of a matchup bonus like 100 to 200% limited to max bonus amount) or like bonus 200 free spins sometimes 100 free spins bonus to start out - in most cases, if a casino offers a bigger number of free spins, like 100 free spins and more, the total bonus amount of extra spins is divided into small portions that are distributed within a certain period - like 20-25 free spins each day. Some gambling companies do even more - casinos offer you a free bonus amount just for signing up with them with no deposit asked for, and there's a common sense to that - this is a great marketing approach to try out the experience and get loyal customers. But, Irish players have to keep in mind that every casino bonus offer comes with related Terms and Conditions.

Every welcome offer comes with a cash wagering requirement that must be met before you can withdraw (this may involve a number of playthroughs for the bonus funds only or bonus & deposit amount - commonly 35x wagering), and a max bonus bet (on average the max bonus bet is between €5 and €7). Another aspect is the validity period (each bonus will expire after some time) - gamblers who play casino games on a regular basis wager their casino bonuses in no time. One more important thing is how different games (slots, jackpot games, table games) contribute to wagering (known also as "weighting requirements" - most casinos offer 100% full weighting on slots) and how winnings can be cashed out (is there a cashout limit for spin winnings, does your payment method qualify, and so on). Please, make sure you read bonus T&Cs (look for "T&Cs apply. New customers only. Opt in required" anywhere on the promotion ad) accurately before you dive in.

Loyalty programs and loyalty points

Gambling companies seek to keep players entertained at their casinos as much as possible, and loyalty incentives serve as a perfect two-way opportunity both for you to get a good profit and for the operator - to keep you away from other online casino brands. A program with loyalty points is a sort of gratitude for the time and funds gamblers spend there. Loyal points can differ, considering the gambling games you choose to play (slots will grant you more points than table games, for instance), as well as the bonus cash wagering requirement you deal with.

While you progress with casino gaming, you reach certain tiers - levels in online casinos' rewards plans. You play casino games and win loyalty points, you advance faster when the amounts you wager are bigger. In most plans, you will be credited with one loyalty point for every EUR10 wagered. Since an online casino in Ireland hardly can provide you with free accommodation or dinner, its loyalty points can usually be redeemed in a form of free spins bonuses, unique casino bonuses, tournament invitations with guaranteed prize pools, and so on. Some online casinos in Ireland have loyalty programs alongside their VIP program (we know this can sound a bit perplexing since both terms have the same semantics here) - in these scenarios, VIP programs tend to offer more substantial, bigger rewards.

Best All-round Irish Online Casino for General Gaming

Not everyone wants to discover just roulette games or just slot games, some Irish gamblers enjoy a bit of everything whenever they log into their account. This is why we recommend King Billy Casino as the best all-around option for Ireland. While this is still quite a new casino, having only launched in 2017, they have already established itself as a brand with a solid reputation and quality customer service to get a better gaming experience. The casino features multiple software partners contributing a wide range of games to suit all preferences from live dealer casino games (like a Lightning roulette wheel, and Caribbean Stud Poker) to the latest electronic offerings. Look out for great deposit bonus offers and exclusive promotions for Irish residents.

Our Best Pick for Slots Players

This category is a tough one to call just because there are so many great options with great slots for the Irish market. However, some do stand out more than others and our choice for top online casinos for Irish slots fans have to be Casumo. It offers hundreds upon hundreds of top slots, all supplied by the biggest names in the online casino industry. Add to that a solid welcome bonus offer amount for new Irish players, fast payouts, and great all-around service.

  • welcome offer package, including generous 1st deposit bonuses and welcome offers

Top Irish online slots review

We do score popular games with players' interests in mind as a primary concern. Without any commitments to top software providers, we've audited games based on truly unbiased reviews to help our readers to make the best decision. CasinoSlots score framework is the gold ration standard for other casino reviews sites.

Legal regulation of online gambling in Ireland

Playing casino games is rooted deeply in Irish culture and is considered one of the must-do events when visiting Éire. As we all know, gambling can be carried out in various forms. Ireland's attempts to redesign its regulatory system and to update, extend and change laws to further engage more efficiently in the modern-day tech-driven casino gaming world, have enhanced the spreading of gambling among the Irish. Ireland became an influential player in the global gaming arena, being able to offer an impressive variety of gaming options, ranging from pool betting (or parimutuel) to lottery, casino slot machines, card poker, and, last but not least, a striking number of iGaming operators have come on the scene with home-grown legitimately licensed Irish casino sites as well as legal gambling casinos managed from overseas (usually these brands are available for a certain number of countries around the world based on their valid license).  Nevertheless, Irish casino lovers need to make sure that they are familiar with the legislation in detail to be able to fully indulge in any gambling activity.

So, Irish Betting Act in 1926 together with the Gaming and Lotteries Act in 1956 has made it illegal for land-based casinos to provide their services all over Ireland - the situation remains the same up to this day. But due to the loopholes in the Law, betting companies managed to find their new path. Games of chance are now concentrated in a form of private membership clubs that are allowed to have slot machines, as well as to provide all kinds of table games and betting. Although there's no single gambling regulator in Ireland presently (like UK Gambling Commission in the UK), a number of public bodies, including the Revenue Commissioners (Irish tax and Customs authority are now responsible for license issuing to betting operators) and Department of Justice and Equality (for overseas applicants for betting licences) share responsibility for regulated online casinos domestically. Starting from 1987, The Irish National Lottery has been offering 3 types of lottery games - Lotto, Daily Million, and Euro Millions, it also hosts TV Bingo games.

An Amendment to the Betting Act in 2015 became a new step forward and helped to pave the way to online sportsbooks (both domestic and offshore included herein), as long as they could obtain appropriate licenses and comply with the legislation.  This, surely, opened up the door wider to the emerging iGaming, i.e. online casino gambling industry on the Emerald Isle. Meaning, Irish casino players can enjoy real money casino games (from card games like online blackjack, poker, or baccarat and other table game to roulette, slots, and live casino games) that they are not allowed to normally access by means of domestic casinos in Ireland (if you take a look at a popular slot Fruit Shop, its sound-track has a sort of nostalgic vibe of fruit slot machines in land-based casinos). Responsible online gaming content (online casinos, online poker rooms, online sports betting, and online bingo included herein) is now entirely legal in Ireland. From this standpoint, CasinoSlots' primary goal is to introduce the Irish player community to safe and secure as well as fully licensed iGaming destinations that comply with Irish Law.
