Weekly cashback is calculated based on your net losses for the week — that is, your total losses for the week minus your total winnings. A fixed percentage of that net loss is returned to your account according to the rate of your current VIP level.
Say you are a Gold level member and your net loss for a week is ৳20,000. In that case: ৳20,000 × 0.9% = ৳180 cashback. This is the maximum amount receivable at that level. Cashback is credited at the end of each week and added directly to your balance.
Cashback applies only in weeks where you have a net loss — if you are in profit for the week, cashback does not apply. This runs on a weekly cycle, so each week is calculated separately.
