What is the Casino Welcome Bonus?
A welcome casino bonus offer is an incentive offered to new players. Sites typically reward players who open an account with them by giving either free bonus spins, match deposits, cashback bonuses, or a combination of these casino promotions. New players can avail of the bonus funds by opening an account with the online casino and wagering real money.
Practically all casinos offer players in Ireland a sign-up bonus. It's a marketing tool that effectively lures new players to play online casino slots for real money on their sites.
Players enjoy massive advantages when they avail of a casino welcome offer since bonuses let them try and bankroll games for free. And given the numerous online casinos in Ireland, players will have plenty of welcome bonuses to choose from and enjoy.
A casino signup bonus is a special type of welcome bonus. The majority of welcome reward require players to make an initial deposit before the welcome bonus can be availed. In contrast, a casino sign-up bonus, as its name implies, only requires players to register an account to avail of the bonus. There is no cash-out or deposits to be made.
Many also refer to the casino sign-up bonus as a no deposit simply because no deposit is required. A no-deposit bonus is a highly-sought after welcome deposit but is typically offered in small value or compared to the traditional casino bonus.

How to Find the Best Online Casino Bonuses in Ireland
It's quite daunting for any player to find the best bonus especially since most online casinos offer them. Plus, welcome bonuses vary from one site to another, making it hard for anyone to compare them thoroughly. So, how can you find the best bonuses?
Real players are the best critics. Find reviews of players from Ireland to get authentic information about other people's experiences at the bonuses casinos. Be sure to use our list to choose a casino that offers best bonuses right away.
When you are already well-versed in the best casino bonus type for your needs, then you should start comparing the online casinos’ bonus offerings. Each casino has its own offerings, use our list to see what's right for you.
Make sure to thoroughly read the T&C before claiming a casino bonus. Many times players end up experiencing unfavorable terms rather than getting a lucrative bonus offering. The opposite can happen too.
Players should also take the time to research the security and license information of the online casino. Is the casino licensed and where? Check the casino licence at the bottom of the casino’s main page. How does the casino protect players' information? Casinos with a good reputation should have digital encryption technology such as SSL (Secure Sockets Layer) and HTTPS in URL addresses.
Types of Casino Bonuses
Online casinos offer various bonuses, which ends up confusing many players. It pays to know and understand the different types of bonuses so you can easily find the best casino bonus for your needs.
The deposit bonus, also known as the first deposit bonus, requires players to make an initial deposit to avail of the welcome bonus. Casinos impose a minimum deposit amount, and you only get to avail of the bonus when you meet the minimum deposit required. What players will get after the initial deposit will vary per casino.
Free spins are typically offered by Irish casinos as part of the welcome bonus package or as a stand-alone bonus. There are conditions with free spins bonus. For example, some casinos only allow free spins to be used on specific games, which usually are the casino’s latest or top-rated.
The no deposit bonus does not require the player to make any deposit. You only need to create an account with the site and verify your identity, and the casino gives you the bonus. Some sites may also offer free spins no deposit bonus or cash no deposit bonus ranging from €5 to €20.
It’s a welcome reward for a deposit, where casinos compensate your initial deposit by a certain percentage, i.e. you can instantly increase the money available in your account. The percentage can range from 100% to 500%. The match bonus is usually the biggest promo coveted online casino bonuses because the more a player deposits, the more he gets back, for example, if you deposit €500 and get a match bonus of 100%, you’ll get an additional €500 on your deposit.
Using the 100% bonus, here's how the match bonus works. For example, the site offers a 100% match bonus. If you deposit €100, then the casino will match it by 100% and give you € 100. This means you will have € 200 in your account.
The 200% match deposit bonus is even more lucrative. The casino, after all, will match your deposit by 200%. This means, if you make an initial deposit of € 100, then the casino will give you € 200. You will then have a total of € 300 in your account.
Reload bonus is typically offered to current players or those who already have an account and have played real-money casino games. Some sites, however, bundle the reload bonus with other welcome bonus types. For example, a match deposit bonus is offered to new players and a reload bonus for succeeding deposits made.
No wagering bonus is rarely offered but it does exist. The most common no-wagering bonus is free spins or no-wagering deposit bonuses. These are similar to the standard free spins and no deposit bonus except that it has no wagering requirements.
Some Irish casino sites offer a welcome bonus, especially for those playing on their mobile devices. If you're in the habit of playing in mobile casinos, then this bonus type suits you.
Cashable VS Non-Cashable Bonus Offer
We already discussed the different kinds of bonuses offered by online sites. But there's another method of classifying bonuses.
Cashable Bonus
Cashable is one of the most basic kinds of bonuses. This is because players can withdraw their initial deposit and bonus as cash after meeting the wagering requirements.
Non-Cashable Bonus
The non-cashable bonus, also referred to as the "sticky bonus", does not allow players to withdraw their bonus. Instead, players can only also cash out the bankroll minus the bonus after they have met the wagering requirements. This is why it is called a sticky bonus, as the bonus sticks to the players' accounts and the casino site. Non-cashable bonuses tend to be bigger than cashable ones since the casino won't lose the bonus amount. The wagering requirements for non-cashable bonuses are also significantly higher.
How to Cash Out Best Casino Bonus
Some Irish online casinos allow players to cash their bonus in real money as long as they meet the terms and conditions. Usually, players are required to meet the wagering requirements as well as the minimum withdrawal amount before the casino site lets them cash out their bonus.
Many casinos also have a verification process for withdrawal requests, and bonuses can only be cashed out after the casino’s verification and withdrawal submission.
Casino Bonus Terms & Conditions
There are also other factors you must consider when comparing welcome bonuses. After all, there's more to bonuses than just the amount being offered. Below are the terms and conditions you need to review and understand before you sign-up for any bonus.
Game weightings are the percentage of the amount used towards fulfilling the wager limits. Usually, slot games have 100% game weightings, meaning video slots contribute 100% to your wager money. So if you use €100 on a video slot game, then the fill €100 is deducted from the wagering requirement.
Win limits are limits on how much you can win real money using the bonus balance. They vary on specific bonus type and per casino. For example, a no deposit bonus typically has a lower limit like a maximum win of €10 while, match deposit bonuses can go in the hundreds or even higher.
Time limits refer to the deadline before the bonus expires or is forfeited. For example, an online casino offering a welcome match deposit bonus has a 14-day time limit. This means you must use the bonus cash within 14 days from the time the cash bonus amount was credited to your account or else it will expire and can no longer be used.
Game restrictions mean you can only use the casino bonus code on certain titles or games. For example, the welcome bonus code offers 50 free spins for a particular slot title like the Book of Dead. You then can only wager the bonus playing Book of Dead and not on other slot titles or games.
Some deposit methods are used by the players not qualified for the casino welcome bonus offer. For example, when the casino excludes e-wallets from qualifying for the welcome bonus, and you used an e-wallet for your deposit, then you cannot claim a bonus.
Players should also look at the wagering requirements when comparing every bonus offerings.
Wagering requirements are the number of times players must bet their bonus money before they can withdraw money from their accounts. Wagering requirements come in multiple. For example, casinos may implement 30x, 35x, or 40x maximum bonus wagering requirements.
This is how it works.
For instance, an online casino site in Ireland may offer a 100% match bonus and you made the first deposit of €100. If the wagering requirement is 35x, then you need to bet €3500 before you can cash out.
Casinos also vary in their wagering requirements rules. Some casinos may impose the wagering requirement on the bonus money and the deposit separately. This means that players will have to wager their deposit money before getting the welcome money for bonus.

The results of our research show that welcome bonuses are a powerful marketing tool used by online casinos to attract new players. They often provide a sign-up bonus that does not require an initial deposit. These bonuses can be either cash-out bonuses that allow players to withdraw after meeting wagering requirements, or they can be non-cash-out bonuses.
In my opinion, understanding different types of casino bonuses, researching their terms and conditions and gambling licenses and comparing offers from different casinos are key steps in getting the most out of these bonuses. Remember that each bonus comes with special conditions, such as game weights, which must be considered in order to have a meaningful gaming experience.
