Reload bonus is a kind of promotion offered by online casinos to their players as a reward for regularly visiting their website and playing. It can be thought of as a reward for loyalty as any player who regularly visits an online casino can qualify for it.
A casino reload bonus can take the form of a percentage deposit bonus, a lesser amount than the welcome bonus, or even free slot spins and other kinds of bonuses. It's a way that casinos use to reward existing customers and encourage loyalty.
