Bonuses offered by gambling operators can vary, but typical promotions grant players bonus funds or free spins to encourage them to use their platform. Bonuses are also designed to encourage players to continue betting using their own money when the bonus funds run out.

Deposit Bonuses: The most common variety of online casino bonus is the deposit bonus or match bonus. It is given away as a percentage of players' deposit amounts. For example, a 100% match or deposit bonus of up to $100 means that the deposit amounts of a player will be doubled to a maximum of $100.
