Every online casino deposit bonus has wagering requirements. While welcome offers are almost always deposit bonuses and/or free spins, casino sites are able to be a lot more creative with their existing customer promotions, even including free physical gifts.

But with online casino bonuses, or any betting offers for that matter, that is unwise.
