No Deposit Bonuses, commonly referred to as NDBs, are a type of casino promotion offered to players as a token of appreciation for registering an account. It is also an incentive for players to try out a casino’s offering, without needing to make any financial commitment. As the name suggests, you don’t need to deposit any money to make use of the promotion - this makes it particularly attractive to newcomers who want to test out the offering.
Generally, a No Deposit Bonus is awarded either in the form of free spins on a particular slot, or as a general bonus in the form of casino credits which you can use to play a wide array of games.
There are some common conditions that come with NDBs, such as wagering requirements and maximum win limits, so it’s best to make sure you read the fine print before activating the bonus. This will ensure that you don’t get any unwelcome surprises later on.
