The short answer is yes, you can claim several bonuses from the same online casino. But you can't do it at the same time. You must finish wagering each one before claiming the next bonus regardless of the type you're using (reload bonuses, welcome bonuses, cashback promotions, VIP bonuses, etc.). With that being said, certain bonus offers and promotions don't come with a wagering requirement. If this is the case, you can generally claim the next bonus immediately. However, it's worth checking the terms and conditions before doing so. If you're looking to get your hands on more than one welcome bonus, you have to register accounts at different casinos.
