This is a fairly complex question, as a lot depends on what type of bonus you want to claim and what terms of use apply to it. What you should definitely check before claiming a particular bonus is the wagering requirements. After all, it does matter if you need to wager the amount of the bonus 15 times or 50 times to initiate a payout. You should also look at what restrictions apply to that particular bonus. For example, in the case of first deposit bonuses, some service providers stipulate that you can only play the bonus on certain slot machines, and also set the maximum amount you can wager per spin (i.e a maximum of €5 / spin). Unfortunately, it is also true that quite a few Irish online casinos do not offer a welcome bonus for those who make their first deposit through Skrill or NETELLER.
