A Big Deposit Bonus is a promotional offer provided by online casinos and betting sites to incentivize players to make larger deposits. Typically, this bonus matches a percentage of the player's deposit, significantly boosting their bankroll and enhancing their gaming experience. For example, a 100% bonus on a $200 deposit would give the player an additional $200 to play with. These bonuses often come with specific wagering requirements, encouraging players to engage more with the platform. However, it's essential to read the terms and conditions to fully understand the offer and maximize its benefits.
