How casino bonus works, its terms and conditions, and its requirement varies with individual casinos. It is usually a way to offer incentives and rewards to customers. Some of the bonuses require you to make an initial deposit, while others don't. The welcome bonus is often a percentage of the deposit you make. It can be from 100 up to c$500. For instance, if there is a 50% bonus and your deposit c$100, you get a bonus of up to c$50, which you can use to play. Some casinos offer no-deposit bonuses, but these are usually small, ranging from c$10 – $50
