How weekly cashback works
A portion of your net losses each week is returned based on your VIP tier.
Weekly cashback is a set percentage of your net loss for that week — total losses minus total winnings. The rate depends on your VIP tier; the higher the tier, the higher the cashback rate.
Example (Gold member):
Net loss in one week: ৳20,000
Gold rate: 0.7%
Cashback: ৳20,000 × 0.7% = ৳140
Cashback reduces losses slightly — it is not a path to regular income.

Live Betting and Cash Out
Bet while the match is in progress and secure your profit at the right moment.
How In-Play Betting Works
Once a match begins, odds change with every wicket, boundary, and goal. Markets may be briefly suspended after a review or key incident.
Popular Live Markets:
- Total runs in the next over (Cricket)
- Type of next wicket (Cricket)
- Innings total runs over/under (Cricket)
- Next team to score (Football)
- Live Asian Handicap (Football)
What is Cash Out?
Cash out lets you settle a bet at live odds before the match ends. It can be used in full or partially, and is available on many markets.
3 Useful Tips:
1. Cashing out when you are winning locks in a profit, but you may have won more if the result holds.
2. If things are going against you, use partial cash out to keep part of your stake active — if the match turns around, the remainder can still pay out.
3. You cannot cash out when a market is suspended — make your decision early at key moments.
