The welcome bonus is normally given to all new players when they join the casino for the first time. How big the bonus will differ from one casino to the next, but 100% up to a certain amount is quite normal.
The bonus is a great way for you to get to know the casino without having to risk too much of your own money. Yes, you can play many slot machines for free, but it’s not the same as playing with real money and there are hundreds of games you can’t play for free.
Qualifying for a welcome bonus is usually very simple. As long as you are a new player, meaning you don’t have an account at the casino already, you will normally qualify. Setting up several accounts with different usernames will not qualify you for an extra bonus. Most casinos will also have a requirement of a minimum amount of money you have to deposit in order to get the bonus, but it’s usually quite low.
