Exactly How Weekly Cashback Works
At the end of every week, bk99 calculates your net loss from your total winnings and total bets. Your VIP tier's cashback rate is then applied to that net loss. If your total winnings are greater than your total losses, no cashback is given that week — cashback only applies in weeks where there is a net loss.
See the example calculation below — this is for the Gold tier, which offers up to 0.6% cashback:
Calculation: ৳20,000 × 0.6% = ৳120 — this is the maximum a Gold tier member can receive that week.
