That’s right! And if a site that you are signing up to offer this then you are only need to think of it as free money.
As people like you are deciding to start gambling online every day the competition is fierce. There are hundreds of online betting websites opening up and all of these want YOU to sign up to their site.
What this means is that they are willing to give you freebies in order to encourage you to sign up to their site.
Once of the ways that they do this is to give you free money for when you sign up. It usually works in a percentage amount. So say for example you top up £10. The new player deposit bonus is 300%. Then they give you an extra £30. You get £40 in your account to bet with anything on their site.
Some sites work differently and will give you a set figure no matter how much you top up and some sites will even give you money to try the site before you fund your account.
These are just extra ways for you to try out the concept of betting online and the sites that you want to use. They are great because they mean you can try the site without spending too much of your own money.
