One of the ways that the online casino operators use to entice us to register with their online casino site is the welcome bonus for new customers. Almost all the online casinos now feature what appear to be attractive casino bonus offers when you first register with their site, and many also offer a second or even a third casino bonus to new customers. These welcome bonuses usually take the form of a 100% bonus to match the customer’s initial casino deposit, which effectively doubles the money the casino games player has to play with, but there are of course a number of terms and conditions associated with all these bonuses, and it has to be said that these conditions do not suit every new entrant to the world of online casino games. The most important of these conditions is what is generally called the ‘ play through requirement’, which defines how much money the casino games player needs to stake on their favourite casino games before they are allowed to withdraw any money from their account. Once the new online casino customer has accepted a welcome bonus, they will be required to gamble a minimum sum of money as defined by the particular play through requirements of that online casino, and this can often be as much as 30 times their initial deposit plus the bonus. There is also often a time limit placed on the play through, and there may also be restrictions on which casino games qualify as part of the play through conditions. Clearly there will be many new online casino games players for whom these conditions would seriously affect their online gambling budget, and ultimately their enjoyment of their casino games. These players should not be tempted by the apparent generosity of the welcome bonuses and should decline the offers. Others may find these online casino bonus conditions perfectly acceptable and for them they provide welcome additional funds.
