A betting app deposit bonus is an enticing promotion offered by online sportsbooks and casinos to attract new users and reward existing ones. Typically, this bonus matches a percentage of the initial deposit, allowing players to start with extra funds to wager on their favorite sports or games. For example, a 100% deposit bonus up to $200 means that if you deposit $200, you'll receive an additional $200 in bonus funds. However, it's essential to read the terms and conditions, as wagering requirements and restrictions may apply before you can withdraw any winnings.
