Big small displays odds in decimal format — the easiest format to understand.
How to calculate: Total Payout = Stake Amount × Odds
- Example: Odds 1.85, Bet ৳100 → Total return ৳185 (Profit ৳85)
- Example: Odds 2.10, Bet ৳500 → Total return ৳1,050 (Profit ৳550)
- Example: Odds 3.50, Bet ৳200 → Total return ৳700 (Profit ৳500)
The higher the odds, the less likely the outcome — but the bigger the payout if you win. Odds of 1.85 mean the platform considers that team more likely to win. Odds of 5.00 indicate an underdog — lower chance of winning, but a bigger payout if they do.
Enter your stake on the betting slip and your potential payout is calculated automatically — no need to work it out yourself.

Wagering requirement (also known as turnover or rollover) means that before you can withdraw bonus funds, they must be used in betting a set number of times.
Let's break it down with an example:
- Say you deposit ৳1,000 and receive a 100% bonus of ৳1,000.
- If the wagering requirement is 10x, you'll need to place a total of ৳1,000 × 10 = ৳10,000 in bets.
- Once you've completed ৳10,000 in turnover, the bonus funds become withdrawable cash.
Important Note:
- Not all bets count toward wagering — typically only bets with odds above 1.5 are eligible.
- You can track your turnover progress in the Bonus section of your account — showing how much has been completed and how much remains.
- Wagering must be completed within a set timeframe — typically 7 to 30 days.
- Full Terms & Conditions on the Bonus page or in the Terms & Conditions available.
