A match bonus is a type of casino bonus that is offered in many online and mobile casinos. It is a type of reward that is given to players who make a deposit, which is typically matched at a certain percentage. For example, a 100% match bonus would mean that players who deposit $100 would receive an additional $100 in bonus funds. The most common match bonus is usually between 50%-100%, although some casinos offer higher match bonuses depending on the amount that a player deposits.
