A Welcome Bonus is a promotional offer provided by companies, especially in the online gambling and gaming industries, to attract new customers. This bonus often comes in the form of free credits, matching deposits, or free spins, allowing users to try out the service without significant financial risk. Typically, to qualify for a Welcome Bonus, new users must create an account and make an initial deposit. The terms and conditions, such as wagering requirements and expiration dates, vary by company, so it's essential for users to read the fine print before claiming the bonus.
