Registration FAQs
66 OBD supports three popular odds formats, and you can choose your preferred format from Settings. Decimal format is set as the default for Bangladeshi players.
1. Decimal — The Easiest Format:
• Examples: 1.80, 2.50, 3.20
• How it's calculated: Your stake × Odds = Total return
• Example: ৳100 stake × 2.50 odds = ৳250 (total return)
• Profit = ৳250 - ৳100 = ৳150
This is the European style and the most widely used.
2. Fractional — British style:
• Examples: 1/2, 5/1, 7/4
• How to read it: 5/1 means you win BDT 5 for every BDT 1 wagered
• Example: You place a ৳100 bet at 5/1 odds
• Profit = 100 × (5÷1) = ৳500
• Total return = ৳100 + ৳500 = ৳600
This is most commonly seen in horse racing and cricket.
3. American — Plus/Minus:
• Examples: +250, -150
• Plus (+) Odds: Underdog — profit on a 100 BDT bet
+250 means ৳250 profit on a ৳100 bet
• Minus (-) Odds: Favourite — how much you need to bet to win BDT 100
-150 means a ৳150 bet returns ৳100 profit
This format is used in American sports (NFL, NBA).
How to change the format:
1. Log in to your account
2. Settings > Preferences > Odds Format
3. Choose Decimal, Fractional, or American
4. All odds will be updated instantly
Tip: The Decimal format is the simplest and quickest to calculate, making it ideal for new players.
If a match is cancelled, suspended, or abandoned mid-game, 66 OBD's bet settlement rules depend on the sport and the specific circumstances. We follow international betting standards.
1. Match Completely Cancelled (Before Kick-off):
If the match is cancelled before it begins:
• All bets Void (Cancelled) Will
• Your full stake will be returned to your account
• No wins or losses will be counted
Example: A cricket match that never starts due to rain.
2. Match Started but Not Completed:
Cricket:
• ODI/T20: If each team completes the minimum required overs (20 overs for ODI, 5 overs for T20), bets are settled via DLS method or the official result
• If the minimum number of overs is not completed, all bets are void
• Test Match: The result at the end of 5 days is final, regardless of outcome
Football:
• If 90 minutes are completed, all bets are valid
• If the match has progressed 70+ minutes and an official result has been declared, bets will be settled accordingly
• If the match is stopped before 70 minutes, all bets are void
Tennis:
• If a player retires or is disqualified, then:
- Match Winner bet: The opponent wins automatically
- Other bets (correct score, etc.): will be void
3. Match Suspended (to be played later):
• If the match resumes within 48 hours, the bet remains valid
• If suspended for more than 48 hours, all bets are void and stakes are refunded
• Live Betting: Bets settled before the moment of suspension are valid; all others are void
4. If one match is void in a Multi-bet/Accumulator:
• Void match odds will be counted as 1.00
• Remaining matches will be settled as normal
Example: In a 3-match accumulator, if one leg is void, the payout is calculated on the remaining 2.
How to check:
Check the status of each bet on the "My Bets" or "Bet History" page: Active, Won, Lost, or Void. For Void bets, verify whether the stake was refunded via your Balance History.
