RTP and House Edge Explained
Understanding RTP and house edge is essential to playing smart at an online casino.
RTP (Return to Player) is a number that shows how much a game theoretically returns for every ৳100 wagered over the long term. For example, a 96% RTP means that on average ৳96 comes back for every ৳100 bet over the long run.
RTP varies across different games. Slot games typically fall between 92–98%, while classic Blackjack played with the correct strategy can offer an RTP of close to 99%. Roulette generally sits around 94–97%.
House Edge is the flip side of RTP — it is the casino's built-in advantage. If a game has an RTP of 96%, the house edge is 4%. This means the casino keeps an average of 4% of every bet over time.
RTP is a long-term statistic — results in a single session can be completely different. Knowing the RTP is useful, but it is not a guarantee of winning. Choosing games with a higher RTP is a smart move, but always play within your own budget.
Bankroll Management Guide
Smart players don't just know how to win — they also know how to control how much they lose.
Set a Budget
Set aside a fixed amount each month for gaming. This should be money whose loss will not affect your day-to-day life.
Divide Your Sessions
Split your monthly budget across weeks or days. Setting a separate limit for each session means you don't risk losing everything at once.
The 1–5% Per Bet Rule
Experts recommend never placing more than 1–5% of your total bankroll on a single bet. This way, one loss won't wipe out your entire balance.
Stop After Winning
Set a target — for example, walk away once you are up 50%. Stopping at the right moment when you are ahead is the smartest long-term strategy.
Respect Your Loss Limit
If you lose 50% of your session budget, take a break. Trying to "chase losses" only increases the risk of losing even more.
Track Your History
Keep a record of deposits, withdrawals, and results for every session. This will help you understand your own playing patterns and make better decisions.
Account Verification Process
KYC verification secures your account and enables uninterrupted withdrawals.
KYC is mandatory for security and legal compliance. It prevents fraud and unauthorized access.
Required Documents
- National ID Card (NID) — clear photos of both front and back
- Proof of Address — utility bill or bank statement
- Selfie Verification — a selfie photo holding your NID
Usually completed within 1–24 hours
Unlimited withdrawals and maximum security
