Betting Exchange — Back vs Lay
On a standard sportsbook you always play against the bookmaker. On a betting exchange you bet against other players — the bookmaker only acts as the platform and takes a small commission.
Example: Say you think Bangladesh will win a match. You place a ৳500 Back bet at odds of 2.0. Meanwhile, another player places a Lay bet on Bangladesh losing. If Bangladesh wins, you win ৳500. If they lose, the player who placed the Lay bet wins.
Exchange commission is usually a small portion of winnings — typically a few percent. Odds on an exchange are often more attractive than with traditional bookmakers because the market sets the odds, not the bookmaker.
| Features | Back Bet | Lay Bet |
|---|---|---|
| You want | Your selected team to win | Your selected team to lose |
| If you win | Odds × stake amount | Back bettor's stake |
| If you lose | Lose the stake | Liability must be paid |
| Role | Regular bettor | Like a bookmaker |
A Guide to Understanding RTP & House Edge
RTP (Return to Player) is the theoretical percentage of total wagers that a game is expected to pay back to players over the long run. For example, if a game has an RTP of 95%, that means on average ৳95 is expected to come back for every ৳100 wagered — however, this is not guaranteed in every session; it is an average across millions of rounds.
The typical RTP range varies by game type. Slot games generally have an RTP between 92% and 98%. Blackjack, when played with correct strategy, can have an RTP of close to 99%. For roulette, the European variant typically falls between 94% and 97%.
House Edge is the flip side of RTP — it is the casino's mathematical advantage. If the RTP is 96%, then the house edge is 4%. It forms the basis of revenue for game developers and casinos. The house edge itself is not a problem — it should be viewed as the cost of an entertainment service.
Understanding RTP and house edge before you start playing is important because it helps you set realistic expectations. Choosing a high-RTP game means you can play longer within the same budget each session. This is a fundamental piece of knowledge for responsible gaming.
Account Verification Process (KYC)
KYC (Know Your Customer) verification is an international security standard for online gaming platforms. It ensures that every account holder is a real person and is at least 21 years of age. This process protects your account from fraud and unauthorized use.
National Identity Card
Upload clear photos of both the front and back of your NID card. Your name and date of birth must be clearly visible.
Proof of Address
A utility bill or bank statement showing your current address.
Selfie Verification
Take a selfie while holding your NID card. The photo must be clear and taken in good lighting.
After Verification
Once verification is complete, your account will be fully activated and withdrawal access will be enabled.
The verification process generally takes some time to complete. Our support team is always ready to assist you throughout the entire process.
