It’s the most popular casino bonus that’s offered by popular operators. In this promotion, you will get a bonus upon registration of the account and initial deposit. Often, it comes as a deposit match bonus up to a certain amount. For example, a casino may offer a 100% bonus of up to €150. This means that the operator is willing to double your initial deposit up to €150. So, when you deposit €150, you’ll start with a bankroll worth €300.
