A no-deposit bonus is a promotional offer commonly used by online casinos and gaming platforms to attract new players. This type of bonus allows users to receive a small amount of free money or free spins without requiring an initial deposit. It provides an opportunity for players to explore the games and features of the casino risk-free. However, no-deposit bonuses often come with specific terms and conditions, such as wagering requirements and withdrawal limits, which players should carefully review before taking advantage of the offer.
