What is a No Deposit Bonus?

To put it simply, the bonus is free money. When you register at a casino, this is normally the first thing you are offered as a welcome bonus. It doesn’t necessarily have to be cash. In fact, more and more online casinos are offering this as a free ‘download’ bonus. You don’t have to spend any money to get it and you don’t have to make any deposits to get it.

You can simply download the casino software, register, download some games, and start playing. You’ll usually be presented with a welcome bonus when you do this.
