77dd Decimal Odds Format — this is the most straightforward format for users in Bangladesh.
The math is straightforward:
Winnings = Stake × Odds
Example:
If you place a ৳100 bet at odds of 1.90:
Winnings = 100 × 1.90 = ৳190 (this includes your original ৳100 stake; net profit is ৳90)
At odds of 2.50: 100 × 2.50 = ৳250 (profit ৳150)
At odds of 5.00: 100 × 5.00 = ৳500 (net profit ৳400)
Keep this simple rule in mind: The higher the odds, the lower the chance of winning — but the bigger the payout. Odds of 1.01 mean a near-certain outcome but a small return. Odds of 10.00 mean higher risk, but a big reward if you win. You can switch to fractional or American format in your settings if you prefer.
