Weekly bonuses at BC.Game, such as the Weekly Cashback, are meticulously calculated based on a proportion of your aggregate wagers or losses throughout a defined period, traditionally from Saturday 00:00 hrs to Friday 23:59 hrs. The percentage applied varies by your VIP status and the explicit stipulations of the bonus. For instance, the Weekly Cashback bonus employs a formula that incorporates your total bets and a predetermined percentage. Conversely, the Sports Weekly Bonus is contingent upon your cumulative sports wagers within the week, with distinct levels proffering varied bonus sums.
