What are Online Casinos?

Online casinos are the result of development by leading online casino companies, with the basic concept being a random number generator(RNG) that simulates the real life behavior of the relevant games, be it a slot machine, cards or roulette. The best online casino providers are well known and established companies such as 
Microgaming, Playtech and Netent. These companies have been around for a decade and sometimes longer, most are publicly traded and constantly under the scrutiny of both accounting firms and local regulators. This means that customers can feel safe in the knowledge that the RNG engines behind these sites are honest and truly random. 
The bottom line is that unlike in brick and mortar casinos, at the online casinos players can rest assured knowing that everything is constantly being monitored and external factors will not come into play with the results of games. Although this theoretically takes away the option of “gaming” the system, these “techniques” are either complete bullshit or illegal.

Comparing Online Casinos

When comparing the best online casinos Ireland it is important to examine both objectively and subjectively. The online casinos we recommend are all highly reputable, safe and easy to use but each casino will have it’s own special bonus offer and specific combination of available games as well as a unique user interface. The best thing a player that is looking for a new online casino to enjoy is to try a few of our top recommendations and only settle on what would be the best online casino for you after playing a bit on a few different ones

Opening an Online Casino Account

Opening an online casino account for users is a rather painless process, basic information that includes full name, address and phone number are basically all that is required when registering for a new account.
The next step is making a deposit, which will of course require the submission of a payment method which can at most cases be either an e-wallet, personal credit card or debit card of almost any kind. Debit cards can be especially useful as they can help keep gaming funds separate from day to day monies and allow for greater control and monitoring.
As you become a regular player and make multiple deposits and withdrawals the online casino operator is required by law to confirm the identity of the account owner which can at times be a bit arduous as scans and documents aren’t always as sufficient as one would expect. Although being a bit of a pain the vast majority of players have no serious issue and manage to supply the regulators demand rather easily.
From here on out is is smooth sailing and you can play, gamble and have fun responsibly as much as you would like.

Top 15 Online Casino Welcome Offers

Welcome or signup casino bonuses can seem like a bit of a mine field to navigate at times, with the less reputable casinos often flashing enticing offers and what eventually turns out to be unattainable terms for actually enjoying the bonus funds. Even some of the more straightforward and known casino brands load up on difficult requirements which mean most new customers do not actually get to enjoy the full bonuses.

We have taken this into consideration and try and feature online casino sites and offers which are attainable, there are going to be terms to adhere to and these offers are not free money but an honest player who puts in a little effort should be able to attain reasonable results by applying to the bonuses featured in our table.
