These bonuses are designed for players to receive a bonus at the particular casino without them having to deposit their own money. Newer casinos tend to use these promotions to get players to try their casino or a new game without any risk.
One thing to bear in mind is the restrictions in place with no deposit bonuses – many online casinos will include a very high wagering requirement or other restrictions in order to reduce the level of abuse they could receive. This means that players taking the no deposit bonus will need to deposit their own funds before they can withdraw the no deposit bonus and subsequent winnings.
Furthermore, wagering requirements and game restrictions will apply. As mentioned in the opening paragraphs, games like blackjack have a low house edge so may not be allowed to be played. Wagering requirements are normally very high for no deposit bonuses compared to other types of casino bonuses as this is completely free money the casino is giving away.
