A deposit match bonus is a promotional offer commonly used by online casinos and sportsbooks to attract new players. When a user makes an initial deposit, the operator matches a percentage of that amount, effectively doubling or increasing the player's available funds. For example, a 100% deposit match bonus on a $100 deposit would give the player an additional $100 in bonus funds. This incentive encourages players to deposit more and enhances their gaming experience, but it often comes with specific wagering requirements that must be met before withdrawing any winnings.
