How to Read Odds
Understand odds before you start betting.
Odds are a number that tells you how much money you will get back if your bet wins. Most online platforms, including those in Bangladesh, use decimal odds, which are the simplest and easiest to understand.
Example: You place a ৳500 bet at odds of 1.80.
You receive = ৳500 × 1.80 = ৳900
That means you get your original ৳500 back plus a ৳400 profit.
You can easily work out the implied probability from the odds. Odds of 1.80 mean that team has roughly a 56% chance of winning.
Comparison of three types of odds:
| Type | Example | Explanation |
|---|---|---|
| Decimal | 1.80 | Simplest — multiply directly |
| Fractional | 4/5 | British style — fraction of profit |
| American | -125 | Expressed as negative/positive numbers |
RTP and House Edge Explained
Know these important facts before you play.
RTP (Return to Player) is the average percentage of total bets that a game returns to players over the long term. For example, if a game's RTP is 96%, then on average ৳96 comes back for every ৳100 wagered — but this is an average across thousands of rounds, not each individual session.
House edge is the opposite of RTP — the portion the casino retains. A 96% RTP means a 4% house edge. This varies depending on the type of game.
Typical RTP ranges for various games
What is Volatility?
Volatility or variance describes how often and how large the rewards are. High volatility games pay out less frequently but in larger amounts; low volatility games offer smaller but more frequent rewards.
Why is this important to know?
Understanding RTP and house edge helps you make informed decisions. Choosing games with a higher RTP means your budget is more likely to last longer. Remember, each round is independent and gaming is always meant for entertainment.
Being an active player means knowing the mechanics of your favourite games — this is part of responsible gaming.
Account Verification Process
KYC — for your protection.
The account verification or KYC (Know Your Customer) process is required to confirm your identity and protect the security of your account. It is an international security standard that protects you from unauthorised access.

Take a selfie holding your National Identity Card. Both your face and the document must be clearly visible in the photo.
