How to Claim Your Casino Bonus Step-by-Step
Irish players can easily get the best casino bonuses in a number of varied ways:
- With the use of a bonus code
- Asking the casino support via either live chat or email
- By simply registering
- Creating an account and depositing a minimum requested amount
- By ticking a box
Let’s analyse every option:
With the use of a bonus code
In this instance, Irish players need to follow a few essential steps:
- Click one of our bonus links
- Register with the casino (if they haven’t yet)
- Go to the Cashier or Deposit section
- Opt for a deposit and select a bonus
- Add bonus code
- Finish the deposit and start your play!
Asking the casino support via either live chat or email
For this, you may just need to create an account, and click on the live chat icon.
Request the promotion from live support by using its clear name.
Or, you can send a similar message on the casino email address.
Stay in touch with casino support!
Sometimes, a sign-up promotion or casino welcome bonus that should be automatically credited after registration may fail to appear in your account. In such situations, we strongly suggest you:
- Keep screenshots of your claiming process;
- Give your sign-up details to the live chat;
- Ask the support agents directly for your bonus.
By simply registering
Some of the best casino bonuses only need Irish players to create an account.
Afterwards, the online casino bonus is automatically credited to your account.
You can make sure that the bonus is automatically credited if you use the Play button you find on CasinoAlpha Ireland!
Creating an account and depositing a minimum requested amount
This process runs just like the first method, but it does not require you entering a bonus code.
Theoretically, you will receive the bonus once the deposit is successfully received by the gambling platform. Other times, the only extra step required is to tick a box and opt for the best online casino bonus Ireland:
This can happen while you register or just as you complete your registration process.
According to the specific online casino bonus type, you may have to skip a few steps. For instance:
- There’s no need to make a payment to access no deposit bonuses, but you may have to register your card;
- Casino offers aimed for existing players, like cashback deals, may only require a deposit or accessing specific games to activate them.

Types of Casino Bonuses Available in Ireland
The best casino bonus is usually one of the following types of bonuses:
| Casino Bonus Type | Definition |
|---|---|
| First Deposit Bonus | A casino bonus is given to new players who are just making their first payment to a site. This may come as a match deposit bonus, rounds on your favourite slots, bonus funds, etc. |
| Welcome Bonuses | Bonus packages known as welcome bonuses are used to attract new players to open an account with an online casino. You receive new player bonuses when you first sign up that let you increase your bankroll without taking on more risk. These deals are only available to new players and encourage them to play more. Only brand-new players are eligible to use this offer. |
| No Deposit Offers | A new casino no deposit bonus can be any amount of bonus funds or rotations received without prior payment to the casino, usually after registering. Popular no deposit offers include 5 euro no deposit bonuses and 10 euro no deposit bonuses Ireland. |
| Free Spins | With free spins, you can play slots for free. You can play famous games for without taking on any extra risk, without making a deposit. If you win with free spins, you’ll need to meet the wagering requirements before you can cash out your money. But some deals include free spins that don’t require you to meet the wagering requirements before you can get your winnings. |
| Reload Bonuses | A way for casinos to reward loyal Irish players who have deposited in the past. Such casino offers can even be second-deposit offers; |
| Cashback Bonuses | These online casino bonuses offer a percentage of your losses or wagers back to you, to encourage continued play; |
| Refer a Friend | As the name suggests, this casino bonus is offered for referring a friend to the casino. Such promotions could be anything from vouchers, to match percentage bonuses, extra rotiations, etc. |
| Existing Customer Offers | If you have already taken advantage of a new player bonus or first deposit deal, you may be able to use a current customer offer. These deals give players extra money and perks as a prize for their loyalty. They often come when your account hasn’t been used in a while to get you to come back and play. |
| Match Deposit Bonus | A match percentage deposit bonus is a promotion that offers bonus funds worth a percentage of your initial deposit. In such situations, most sites will require Irish players to play their bonus funds first, and then their deposit. Be aware! Most match deposit bonuses are capped at a specific amount. So, while the percentage may be quite high, this does not help if the terms stipulate that bonus funds are capped at a low sum. |
How We Test Casino Bonuses for Irish Players
- Bonus Value: We test the best casino bonus’s value by creating real casino accounts and making a deposit to obtain the maximum bonus value. Our experts also calculate the true bonus value and how convenient it is, depending on wagering and other bonus features.
- Multiplier: Our team wagers each sign up welcome bonus to obtain winnings. We then check the casino account profile to see if the multiplier works correctly. We also check the terms and conditions for rules related to accessing multiplied winnings.
- Min. Deposit: To access many casino welcome bonuses we also transfer the minimum deposit mentioned in the promotional terms, using multiple payment services. We test how quickly the deposit appears in the casino account and if it activates the right amount of bonus funds.
- Max. Cashout: After obtaining winnings and completing the bonus playthrough, we proceed to cashout. We go through all the necessary steps, and test how much we can actually withdraw, how quickly the transaction is processed, and which payment methods we can use for payouts.
- Wagering: When testing the wagering requirements for casino bonuses, we look at the betting limits and how easy they are to complete within the bonus availability. We also check if the RTP of eligible games is high enough compared to the playthrough requirements, to give you a winning chance.
