That said, many online casinos tend to restrict how much they can lose by enacting what is known as wagering requirements, which place a mandate on how many times you will have to wager your bonus before they allow you to withdraw it.
They will come under a few different names, depending on the location and company, so just doing a search for one term will not always produce the results that you are looking for.
The general definition of this is classed as the number of times that you will need to bet past your wager in order to be able to withdraw this money.
Some examples tend to give you additional funds if you invest a certain amount yourself, which are often known as matched bets. In this situation, you would end up with $20 in the account, half of which came from you, and you would then have to reach that $300 worth of gambling before you could ask to take the money back out.
The chances are that for these individuals, they would be expecting to gamble that figure or much more anyway, and therefore it is of little concern. However, for those who like to be more free with their betting habits and not feel required to bet just to get closer to withdrawing, it could take a while to get that far.
For some people, this is no problem at all
One other aspect in terms of limitations is linked to which games you can actually play while using your welcome bonus. It turns out that many of these only allow you to play slot games, and specific ones at that, instead of something such as baccarat games.
While this can be frustrating, it is worth pointing out that this does not necessarily apply to all casinos, and each one will have some variance on this.
As for why it seems to be set up like this, it has to do with what value each game offers to the house. As an example, blackjack games are typically less profitable than slot games for the online casino, simply because of the way that margins work.
If there is a certain amount of money levied on a blackjack game, then the casino can win a set and certain amount, but never more than that. Slot games, on the other hand, have their randomisation process set so that the odds are a bit more in their favour for what they recover in cash from the average player.
If the casino provides you with a $10 deposit, then you would have to gamble with them to the tune of $300 before you could do anything else with the funds
Of course, this is one of the obvious reasons that some people prefer to play the likes of blackjack and roulette – the odds can be much clearer, and it is far clearer to figure out exactly what you would need to do to win on a hand or spin, while slots possess less skill in this regard.
This aspect of chance is hugely important to how it attracts people in, as many will believe that they are more likely to win by playing blackjack games than on slots over a specific period.
In many ways, this is completely true. That said, it begins to make sense why you would see many bonus schemes set up for slots and not for anything else, and that is because they offer more value for the casinos. This is not to suggest that this is the prie so heavily, and in fact it comes down to their attractive and fresher-looking visuals as much as other aspects.
