A 5 Deposit Bonus is a promotional offer commonly found in online casinos and betting sites, where players receive a bonus after making their first five deposits. Each deposit typically earns a percentage match bonus, enhancing the player's bankroll and extending their gaming experience. This incentive encourages new users to engage more with the platform, as it provides additional funds to explore various games or betting options. However, players should always check the terms and conditions, including wagering requirements, to fully understand how to maximize their bonus benefits.
