Best Blackjack Sites Ireland - Our Top 20

Advantages of Playing Blackjack Online

Blackjack, also called 21, is the most popular game at casinos. It’s fun and simple, and you can reduce the house’s edge with a little strategy. Here are several advantages to choosing blackjack sites ahead of land-based casinos:

• Convenience. You can play blackjack 24/7 just by grabbing your phone or turning on your laptop or desktop. It's all about your style and speed—no need to get all dressed up or drive to a casino. You don’t have to worry about gas, taxi fares or public transport costs. You can also use alternative payment methods to make things easier. Pay by phone casinos are pretty popular in Ireland.
• Value. Playing blackjack online is much cheaper because you don’t need to tip the dealers. And, unlike in real casinos, you won't have to spend cash on snacks and drinks while playing, which is a nice bonus!
• Variety. You can choose from dozens of great games at a blackjack casino. Pick the version you prefer, whether that's the one with the best RTP or the betting limits that fit your style. Best of all, you don't have to wait for a seat - hop on a virtual stool and start playing. And if you miss the vibe of a land-based casino, you can still get that with live blackjack. You can chat with other players and the dealers; there's often plenty of banter to enjoy here.
• Bonuses. The best blackjack sites in Ireland offer large bonuses to stand out in this crowded market. They help reduce the house edge - already low in blackjack - and improve your profit chances.
• Security. You don't have to worry about carrying cash or winning a large lump sum. Our recommended blackjack casino sites offer safe and secure casino payment options.

Best Blackjack Bonuses Ireland

There are lots of ambitious blackjack sites vying for your business, and many of them offer exciting bonuses to stand out. They include sign-up bonus and reload bonuses, free bets and loyalty schemes. 

Many casino welcome bonuses are for the best real money slots online, though many also include table games like online roulette. 

Before you claim anything, read the bonus terms and check the wagering requirements. They're just as important as the bonus size. 

Blackjack Wagering Requirements

When searching for the best online casino bonus deals for blackjack, wagering requirements play a big role in how much you can withdraw. You’ll need to play through your funds several times before cashing out any winnings. Timing is also crucial. If you don’t meet the requirements within the given timeframe, you could lose your bonus.

As a high-RTP game, blackjack usually counts 10% towards the wagering at most casinos. This means you'll have to wager your bonus winnings more than slots, most of which contribute 100%.

It might sound tricky, but with our wagering calculator, you can figure out exactly how much you need to wager in seconds. Click on the image below, enter your bonus details, and hit 'calculate' - it's that easy!

High Stakes and Low Stakes Blackjack Casinos Online

The best blackjack sites cater to all players by offering broad betting limits. Low-stakes players can find games with a bet as low as €5 per hand, while high rollers will find VIP and Salon Privé games with very high upper limits. 

If you bet large amounts, pay attention to the limits on how much you can deposit or withdraw when selecting a blackjack site. Luckily, the best online casinos often reward high-stakes players with various perks.

Broad table limits are also important if you're pursuing some of the more aggressive progression systems. For example, the Martingale System requires you to double your bet after each loss. 

If you start by betting €20 and suffer nine straight losses, you will need to wager €10,240 on the next hand. The system falls apart if you run up against table limits and cannot place the correct size bet, so finding a site with broad limits is vital.
