The online casino world is full of bonuses and although we try here at oninecasino.ie to keep you up to date they are changing so quickly that it becomes a difficult task. The most popular bonuses are the sign up bonuses which are available only once in your relationship with your chosen online casino and as such you should treat them with a little bit of consideration. Online casinos like to attract new players to their site and they do this by offering seemingly attractive offers of free money but the competition is such that all online casinos now offer new players bonuses. These bonuses usually come in the form of what is called a 100% matching deposit bonus and what it means is that for every €1 that you deposit, the casino will give you €1 but be aware that it is often on your first deposit only and of course there are maximums. This means that if you wish to try out a new casino and deposit €10 the online casino will add €10 to your account but if you later find you like it and wish to deposit a larger amount, say €100, the 100% deposit bonus is no longer available. Some online casinos are now offering matching bonuses on your second or even third deposits but they are often only 50% or 25% of your deposited amount. Sign up bonuses should never be the only reason to register with an online casino because, as we said, we hope your relationship with your online casino lasts a long time and this bonus is a once in a lifetime award. Look out for casinos online that offer regular bonuses to players or loyalty schemes, you may find these better in the long run but the real reason to sign up is to enjoy your gambling so choose a site that you feel comfortable with and even if you ignore the bonus offered, it is not the end of the world.
