There may be times you'll need to meet certain betting conditions before a bonus is triggered. This is known as a qualifying bet. For example, you may need to wager your own money on minimum odds to receive a bonus bet.
There are times when a deposit bonus is only triggered once you've made a minimum deposit. For example, you'll need to credit your account with a certain amount to claim a deposit match. Similarly, no-deposit bonuses usually require you to bet $10 or more on a specific event.
