An online casino deposit bonus is a promotional offer that rewards players for making a deposit into their gaming account. Typically expressed as a percentage of the deposit amount, this bonus allows players to enjoy extra funds or free spins, enhancing their gaming experience. For example, a 100% deposit bonus means that if a player deposits $100, they receive an additional $100 to play with. These bonuses often come with specific wagering requirements, encouraging players to explore the casino's games while maximizing their chances of winning. Always read the terms and conditions to make the most of these offers.
