The most popular type of promotion in the online casino world is the wide range of deposit bonuses available. Casino bonuses compare with each other in different ways, and there are even no deposit bonuses that offer the chance to win real money prizes without having to bet (more on that later). Fundamentals of deposit bonuses are the percentage match you get and the maximum size of the bonus itself. This tells you the basic parameters of the bonus opportunity. For example, you could get a 100% match worth up to £ 200. If you bet £ 75 with this offer, you would get a £ 75 bonus. However, if you deposit £ 225, you will only get £ 200 since that is the maximum amount you can earn with this deal. When it comes to campaigns, compares online casinos primarily based on their approach to maximum and percent. As one increases, the other decreases as a general rule.
