How to Read Odds
Odds are the language of betting — understanding them means you'll know how much you can win and where the probability is higher. There are three main formats:
Decimal Odds
The simplest format. If you bet ৳500 at odds of 1.80, your total return will be ৳900 (৳500 × 1.80). Profit: ৳400.
Fractional Odds
Common in the British betting market. 4/5 means ৳4 profit for every ৳5 wagered. In decimal, 4/5 = 1.80.
American Odds
Used in the US market. A positive number (e.g. +250) means ৳250 profit on a ৳100 bet; a negative number (e.g. −125) means you need to bet ৳125 to win ৳100.
Implied Probability: Odds of 1.80 mean the event has roughly a 56% chance of happening. The higher the odds, the lower the chance of winning but the greater the reward.
Payment Methods
Deposit a minimum of ৳300 at kb688. Withdraw from as little as ৳500, directly to your mobile wallet — usually within 30 minutes to 3 hours.

| Nagad | Those who prefer postal services | Select the Nagad option, enter your mobile number, and verify with OTP | No extra fee |
| Rocket | Dutch-Bangla Bank customers | Choose Rocket, enter your account number, and confirm | No extra fee |
| Upay | UCB Bank app users | Choose Upay and send from your mobile wallet | No extra fee |
| Bank Transfer | Those interested in large transactions (Dutch-Bangla, BRAC, Islami Bank) | Choose bank transfer, collect the account details, and send via net banking | The bank's own fees may apply |
