Decimal Odds
The simplest format. If the odds are 1.80 and you bet ৳500, the total return will be ৳900 (meaning a profit of ৳400).
Formula: Bet amount × Odds = Total return.
Fractional Odds
Popular in British horse racing. "4/1" means ৳4 profit for every ৳1 wagered. So on a ৳500 bet, the profit is ৳2,000 and the total return is ৳2,500.
American Odds (Moneyline)
"+200" means ৳200 profit on a ৳100 bet. "-150" means you need to bet ৳150 to win ৳100 profit. Positive = underdog, negative = favorite.
Implied Probability
Calculating probability from decimal odds is straightforward: 1 ÷ Odds × 100 = Probability (%). Example: odds of 2.00 give a probability of 50%. Working this out before placing a bet makes it easier to decide.
RTP and House Edge Explained
RTP, or "Return to Player", is a figure that shows how much of total bets a game returns to players over the long run. For example, a 96% RTP means an average of ৳96 is returned for every ৳100 wagered — but this is a long-term mathematical average, not a guarantee for every session.
House edge is the opposite of RTP: 100% − RTP = House Edge. In a game with 96% RTP, the house edge is 4%. This means the casino keeps an average of ৳4 from every ৳100 wagered over the long term.
RTP ranges differ across game types: slots are typically 92–98%, blackjack is around 99%, and roulette can reach 94–97%. A higher RTP means a lower house edge — but volatility and your personal betting strategy also matter.
Being aware of RTP and house edge before you play helps you set realistic expectations and makes it easier to plan your budget.
Bankroll Management Guide
Experienced players do not rely on luck alone — they plan ahead.
1. Set a Budget
First, decide how much you can afford to lose. This is your "gaming budget" — never take it from household expenses, rent or savings. Set a fixed limit each month and commit to not exceeding it.
2. Divide into Sessions
Split your monthly budget into equal sessions. For example, if your monthly budget is ৳3,000 and you play three days a week, set aside ৳250 for each session. When a session's funds are gone, stop for the day.
3. The 1–5% Rule Per Bet
It is best to keep each bet to no more than 1% to 5% of your total session balance. This way, a single bad result cannot wipe out your entire balance. Avoid putting everything on one bet out of temptation for a big jackpot.
4. Take a Break After a Win
After a big win, resist the urge to immediately increase your bets. Withdraw a portion of your winnings and continue playing within your set limit with the rest. Winnings that are not withdrawn remain just a number.
5. Set a Loss Limit and Stop
Decide in advance how much loss will make you stop for the day — for example, 50% of your session budget. Placing more bets after a loss to try to recover often leads to bigger losses.
Account Verification Process (KYC)
Account verification, or KYC (Know Your Customer), is a normal and important process. It ensures the security of your account and helps prevent fraud.
Required Documents
- National ID (NID)
- Proof of Address
- Selfie Verification
Processing Time
Usually completed within 1–24 hours. You will be notified by email or live chat once verification is done.
Once verification is complete, you will have full access to all services including withdrawals. If you have any questions, get help in Bengali on live chat.
