No deposit bonuses are one of the most sought after bonuses by casino players. They allow players to get a boost to their bankroll with no risk involved. A no deposit bonus is a type of casino bonus given to players without the need to deposit any of their own money. Players are usually given a very small sum of free money, often referred to as free credits, to play the casino games. These bonuses are designed to attract new players, as well as, give existing players an extra reward to try out a new game.
