A gambling bonus is an incentive offered by online casinos and sportsbooks to attract new players and retain existing ones. These bonuses can come in various forms, such as welcome bonuses, free spins, or cashback offers. Typically, they require players to meet specific wagering requirements before they can withdraw any winnings. While bonuses can enhance the gaming experience and provide extra funds to play with, it's essential for players to read the terms and conditions carefully to understand the rules and limitations associated with each offer.
