There is a great deal of competition out there in the online casino world and a very common way for online casinos to attract new business is to offer a casino bonus. Just occasionally an online casino will offer free cash as a form of casino bonus and generally at casinos.ie we shall alert our readers to this offer. The idea is to get you signed up and playing games without even making a deposit into the casino but the most common is what is called the deposit match bonus whereby the online casino will offer to match your initial deposit into the casino by a certain percentage. This can be 100% which in effect doubles the money that you have available to play and sometimes this type of casino bonus can extend to your second or even third deposits but usually the percentage match is lower. At casinos.ie we are all in favour of online casinos offering welcome bonuses in this way to new players but we would caution those who think that they can play a few games and withdraw the cash as that is not the case. Online casinos provide the bonus to allow you to have more enjoyment playing the various casino games and for this reason they will place restrictions on when you can withdraw this bonus money. The most common restriction is what is called a play through requirement whereby the online casino will require you to stake a multiple of the bonus on games before it becomes available for withdrawal and to make it even more difficult it is not unusual for low risk casino games such as Blackjack or Roulette to be excluded from counting towards the play through requirement. Online casino bonuses are great and if you intend registering with an online casino then by all means select one with a good bonus although that should not be the only criteria for your selection..
