If you look at any online casino and are thinking about signing up you will be probably be impressed with the bonuses that they appear to be giving to new casino players and there seems to be a bit of a competition going on between them to have the biggest casino bonus but as with everything which seems a bit too good to be true you need to be a little bit careful. Online casinos are not about to give away free money and there are a number of ways in which they offer a casino bonus but make it difficult to get your hands on it and withdraw it the first of which is what is called the “play through requirement”. What this means is that in order to get your bonus money you will need to bet or stake the bonus a number of times over. Most casino bonuses at online casinos are what are called deposit matching bonuses which means the casino will match your deposit by a percentage which on your first deposit into an online casino is usually 100%; it is possible at some online casinos also to get a matching deposit bonus on your second or even third deposits but they are generally at a smaller percentage such as 50% or even 25%. The play through requirement can be expressed either as a multiple of your bonus or as a multiple of your bonus PLUS your deposit so make sure you know which one it is. The higher the play through requirement is, the less likely you are to actually reach the requirement to be able to cash out. If you are thinking that the betting requirement looks reasonable because on games such as roulette the odds of winning are quite good then take a look at the small print of the casino bonus offer and you will find that bets on roulette only count for 10% or often not at all towards the play through requirement. Casinos.ie is not saying that a casino bonus is no good because after all the worst that can happen is that you play for longer than you would have otherwise but if you are expecting to withdraw cash you might be disappointed.
