Generous sign-up bonuses are a must-have in terms of loyalty to an online casino. What usually happens is online casinos calculate the amount of free bonus money that players should receive when they enter their first and second deposits. After you make a deposit, the game will usually tell you how many credits you have accumulated, which is then followed by how much of your bonus you’ve used up. If any part of your deposits or bonuses were given as fake free money, then it might not be worth as much later on.
