How weekly cashback works
Each week, your net loss is your total losses minus your total winnings. You receive a set percentage of that net loss back — that is the weekly cashback. The higher your losses, the higher your VIP tier and the higher your cashback rate.
Cashback reduces losses to some extent — but it is not a winning strategy. Please bet responsibly.

Learn to read betting odds
Bettors in Bangladesh generally encounter three types of odds formats. Learn what each means and how to calculate returns.
The most common format. Multiply your stake by the odds to get the total return — the stake is included in that figure. For example, 3.00 means a ৳100 bet returns ৳300 (profit ৳200).
Example 1: Team A win odds decimal 3.00, stake ৳500
If you win: ৳500 × 3.00 = ৳1,500 (profit ৳1,000)
If you lose: you lose ৳500.
Example 2: Team B favourite, odds 1.80, stake ৳500
If you win: ৳500 × 1.80 = ৳900 (profit ৳400)
The British system — written like a fraction. The left number is profit, the right number is stake. 2/1 means ৳2 profit for every ৳1 staked.
Example 1: Team A odds fractional 2/1, stake ৳500
Profit: ৳500 × (2÷1) = ৳1,000
Total return: ৳1,500
Example 2: Team B favourite, odds 4/5, stake ৳500
Profit: ৳500 × (4÷5) = ৳400
Total return: ৳900
A + sign means how much profit you make on a ৳100 bet; a − sign means how much you need to bet to make ৳100 profit.
Example 1: Team A odds American +200, stake ৳500
Profit: ৳500 × (200÷100) = ৳1,000
Total return: ৳1,500
Example 2: Team B favourite, odds -125
You need to bet ৳125 to make ৳100 profit. On a ৳500 bet, profit is ৳400, total return ৳900
Remember — these figures are for illustration only; bet within your means.
150%
Welcome bonus on first deposit
Example: Deposit ৳1,000 and get a ৳1,500 bonus, giving a total balance of ৳2,500. Wagering requirement: ৳1,500 × 10 = ৳15,000. The bonus is not free money — it is a credit that can be withdrawn once specific conditions are met.

Many players start betting with certain common beliefs — it is worth checking whether they hold up.
"This slot hasn't paid out in a long time — it's due."
FactEvery spin is completely independent and random. Previous results have no effect on the next round — slots have no concept of being "due".
"I've been losing in a row — I'm bound to win now."
FactA losing streak does not guarantee a win. Each round is separate and the house edge stays the same throughout.
"There's a system that guarantees winning at Baccarat."
FactNo strategy can eliminate the house edge. The Martingale and any other system only increases losses over the long run.
"Depositing more gives a better chance of winning."
FactThe amount you deposit does not change the outcome of any individual round. A bigger bet also means bigger risk.
"You win more if you play at night."
FactThe RNG (Random Number Generator) has no concept of day or night. Results are determined by the same rules at all times.
"New accounts win more."
FactThe age of an account plays no role in game outcomes. RTP and volatility are the same for all accounts.
Betting is entertainment — for adults aged 21 and over. Set your own limits.
