- Fully Cancelled: If a match is cancelled before it starts, your full stake is refunded to your account — usually within 1–2 hours.
- Abandoned mid-match (cricket): If the required number of overs (typically a minimum of 5 overs in an innings) have been completed, the result is settled under D/L rules. If not, the bet is voided and the full stake is refunded.
- Suspended mid-match (football): If play has exceeded 45 minutes but the match is not completed within the following 12 hours, the result may be determined by the score at that point — depending on the market type.
- Accumulator Bet: If one event in a combination is cancelled, the bet is recalculated using the remaining events.
Note: If you have any questions about a settlement, check the "Bet History" section of your account for full details, or contact support with your bet reference number.
Wagering (or "rollover") means you must bet a specified multiple of the bonus amount before you can withdraw it.
Let's walk through an example:
- You deposited ৳1,000 and received a ৳1,000 bonus under the 100% bonus offer.
- A ×15 wagering requirement on a bonus means ৳1,000 × 15 = ৳15,000 Total Betting must be completed.
- This ৳15,000 wagering requirement does not mean placing one large bet — it is met once the combined total of all your bets reaches ৳15,000.
- Once the conditions are met, the bonus balance automatically becomes withdrawable.
A "Wagering Progress" bar is visible on the bonus dashboard, so you can check how far along you are at any time. Full terms Terms & Conditions on this page.
3999bt displays odds in Decimal format — for example, 1.85, 2.50, 3.40. This number shows your total return per BDT staked, including your original stake.
Simple calculation:
- Odds × Stake = Total Return (including original stake)
- Example 1: Odds 2.00, stake ৳500 → win ৳1,000 (profit ৳500)
- Example 2: Odds 1.85, stake ৳1,000 → potential return ৳1,850 (profit ৳850)
- Example 3: Odds 3.50, stake ৳200 → win ৳700 (profit ৳500)
Higher odds mean a lower chance of winning, but a bigger payout if you do. Odds below 1.00 fall outside the scope of betting. Enter your stake on the betslip and the "Potential Winnings" figure is calculated automatically — no manual math needed.
Format change: In your 3999bt account settings, you can switch the odds display format to Decimal, Fractional, or American — whichever you prefer.
