tk 668 supports three odds formats:
1. Decimal Odds — the most common format: If the odds are 2.50, a ৳100 bet returns ৳250 in total (৳150 profit). The formula: Stake × Odds = Total Return.
2. Fractional Odds: For example, odds of 3/2 mean you earn ৳3 profit for every ৳2 staked. This format is rarely used in the Bangladeshi market.
3. American Odds (Moneyline): +150 means ৳150 profit on a ৳100 bet; -150 means you need to bet ৳150 to win ৳100 profit.
Head to tk 668 settings to switch to your preferred odds format. Decimal odds are the easiest to understand for beginners. The higher the odds, the less likely a win — but the bigger the payout if you do.
