Well, a reload bonus is essentially a bonus that you receive after your initial first deposit welcome offer. It can be a site-wide promotion available to all existing players or it could be a bonus exclusively for you and other qualifying players. It could be rewarded to you for making your 2nd, 3rd and 4th deposit as part of your welcome package or it could be a daily promotion available all throughout the year. You simply need to read the T&Cs, make a qualifying deposit, claim the bonus and get playing!
