Percentage Bonuses are contingent upon the amount of one’s deposit, and usually range from 50% to 450%. The most common percent bonuses are 50%, 100% (match) and 200%. The percentage of the bonus determines how much of one’s initial deposit will be awarded in bonus money. Of course, this is in addition to the deposit itself. For instance, a 200% bonus for a $50 deposit would amount to a $100 bonus, giving the player a total of $150 to gamble with.
