Whenever an online casino offers a bonus there are always terms and conditions attached and these are often in the form of “play through requirements” but what are they and what do they mean? The principle behind it is simple enough in that the online casino does not want players claiming a bonus and withdrawing the cash so they insist that you play at the online casino with the money they have given you but there are differences in these terms and conditions between online casinos at casinos.ie which are worth looking out for. The play through requirements are usually expressed in terms of the number of times a casino bonus must be played before money can be withdrawn; if for example you received a bonus of €50 with a play through requirement of 20 times you would need to place bets to the value of €1000 before you could make a withdrawal. When comparing online casino bonuses do not only consider the number of times of the play through as online casinos quoting small play through requirements can often be applicable to both your deposit and the bonus instead of simply the bonus. Another common condition is that casino games with a small house margin such as roulette will often either not count at all towards the play through requirement or only for a very small percentage; even card game such as blackjack can often be excluded. Although it is very easy to ignore the terms and conditions of a casino bonus and indeed you need to click through a couple of times to get them on the site it is well worth doing to make sure you know what is going on and of course it makes it that much more difficult to determine which bonus is better than another one..
