3rd deposit bonus funds are much like 1st deposit bonus funds, only that you do not receive the bonus from your first deposit. The 3rd deposit bonus funds offer is not very common, or at least you are more likely to see other bonuses before you come across a 3rd deposit bonus. As with all deposit bonuses, the 3rd deposit bonus amount is just extra funds and are subject to the conditions of the wagering requirements, so remember to gamble responsibly.
