A no deposit bonus is a type of promotion offered by online casinos. It allows players to receive bonus funds without having to make a deposit. This bonus is often given as a reward for signing up or as an incentive to try out new games. Players can use the bonus funds to play real money casino games and potentially win cash prizes. However, there are usually wagering requirements attached to no deposit bonuses that must be met before any winnings can be withdrawn. Overall, no deposit bonuses can be a great way for players to explore online casinos without risking their own money.
