A casino deposit bonus is a promotional offer that rewards players for making a deposit into their gaming account. Typically, this bonus comes in the form of a percentage match on the initial deposit, allowing players to enjoy extra funds to play with. For example, a 100% deposit bonus means that if a player deposits $100, they receive an additional $100 in bonus funds. These bonuses often come with specific wagering requirements, meaning players must bet a certain amount before they can withdraw any winnings derived from the bonus.
