It used to be the case that an online casino bonus was only for new players and of course new players to an online casino will still receive considerable bonuses usually in the form of a deposit matching bonus but these days there are many other casino bonuses available even to existing players. Casinos.ie would never recommend registering at an online casino just for the bonus but if you have already signed up you might as well take advantage of what is being offered which usually entails simply keeping an eye out and registering using a special code that you can find on the site. For example Paddy Power casino has what is called T Junction Tuesday casino bonus which gives you a 100% deposit match every Tuesday to play slots or Blackjack; the Blackjack casino bonus is up to €25 and must be played through 100 times and he slots casino bonus is up to €100 and must be played through 32 times. Party Casino is offering an unusual casino bonus called Instant Reward Cash Bonus and all you have to do is be in the right place at the right time and there is also a Reload Bonus which matches your next deposit to a certain percentage. Ladbrokes are focussing on their live casino offering for some of their casino bonus offers for example the Lucky Ref Card promotion where you can given red or yellow cards worth up to €25 simply by playing at the blackjack table or there is Top Up Thursday which gives you 25 free spins on Tomb Raider II when you deposit as little as €50 and the turnover requirement is only 2 times or €100. There are plenty of other casino bonuses available for existing online casino players so keep your eyes open..
