Betting Basics
By default on a88o Fractional FormatOdds are shown in decimal format, such as 2.50 or 1.80. This number is the multiplier applied to your stake if you win. For example: odds of 2.50 on a ৳100 bet → you receive ৳250 if you win (৳150 profit + your original ৳100 stake). The higher the number, the bigger the potential payout – but the lower the probability.
In some sections Fractional Format (e.g. 3/2 or 5/1) – the left number is your profit and the right is your stake. 5/1 means a ৳100 bet returns ৳500 in profit. Money line format (+150 or -200) is mainly used in baseball and appears less frequently on a88o.

Withdrawals & Payments

Before your first withdrawal: KYC verification is mandatory. Submitting a photo of your national ID verifies your account and activates withdrawals. Once verified, you won't need to go through the process again.
