It seems that all online casinos want to attract more customers and apart from heavy advertising most of them seem to think that offering a casino bonus to new players is a good way to do it but often these casino bonuses are quite hard to make any real money from as the casino bonus is paid into what is called a bonus account which is not immediately accessible. These casino bonuses are often what is known as deposit matching bonuses which means that the online casino will place into your bonus account an amount which is a percentage of your first deposit into that online casino. This is generally a 100% match but will be less if the casino bonus extends to your second or third deposit and whilst it is true that this money can be used to play any of the casino games of your choice it is much more difficult to get your hands on the cash if you win. Online casinos using this sort of casino bonus will have what is called a play through requirement which means that you must stake your bonus a number of times before any winnings can be withdrawn and this can be 20 or 30 times or more. Be careful also that some online casinos make the play through applicable to your deposit plus the bonus which effectively doubles the requirement and very often what are considered to be lower risk casino games such as Roulette do not count towards the requirement at all. There are alternatives to this arrangement such as at www.nobonuscasino.com which instead of offering a casino bonus to new players gives a 5% cash back if you are unfortunate to lose all your deposit under certain circumstances and this is applicable to all deposits into the casino whether you are a new player or not.
