An accumulator or parlay is multiple bets placed together. You win if all bets are correct, and the payout is much higher. How to place an accumulator on 57abc:

• Choose your first match: Click on any match from the Sports section and select a market (e.g., Home Win in football). It will be added to your bet slip.
• Add more matches: Select markets from the second, third, fourth matches. Each will be added to the bet slip. You can combine up to 20 matches.
• Select the Accumulator option: At the top of the bet slip, you'll see "Single," "Multiple," and "Accumulator" options. Click "Accumulator."
• Enter bet amount: Enter how much you want to bet. Your potential winnings will be calculated automatically.
• How it's calculated: All match odds are multiplied together. Example: You bet on 3 matches with odds 1.80, 2.00, 1.50. Total odds = 1.80 × 2.00 × 1.50 = 5.40. If you bet BDT 1,000 and win, you'll receive BDT 5,400.
• All bets must win: If even one match is wrong, you lose the entire accumulator. So choose carefully.
• Bonus odds: When you accumulate 5 or more matches, 57abc gives bonus odds (e.g., +5% to +25% depending on number).

Accumulators carry higher risk but much bigger potential winnings. If you're new, start with 2–3 matches and build your experience gradually.

Odds on 57abc are typically shown in Decimal format, the simplest and most widely used globally. To understand Decimal odds and calculate winnings:

• What are Decimal Odds: This is a number that shows how much you'll get back for every BDT 1 wagered (including your stake). For example: 2.50 means you'll receive BDT 2.50 for every BDT 1 bet.
• Calculating your winnings: Total payout = Bet amount × Decimal Odds. Example: You bet BDT 1,000 at 1.80 odds. If you win, you'll receive 1,000 × 1.80 = BDT 1,800. This includes your original BDT 1,000 stake plus BDT 800 profit.
• Profit only: Net profit = (Decimal Odds - 1) × bet amount. Example: (1.80 - 1) × 1,000 = 0.80 × 1,000 = BDT 800 profit.
• The higher the odds, the lower the winning chance: High odds (e.g., 5.00 or 10.00) mean much higher winnings if you win, but lower chance. Low odds (e.g., 1.20 or 1.50) mean smaller winnings but higher chance of winning.
• Change odds format: If you prefer Fractional (5/1) or American (+200) odds, you can change the odds format from settings. But Decimal is the easiest.
• Live Odds: In-play odds change in real time. During a match, the odds for the leading team decrease while the trailing team's odds increase.
• Automatic calculation in bet slip: When you enter an amount in the bet slip, "Potential Win" is automatically displayed. No need to calculate.

If you're new, start with safer bets at lower odds and gradually learn how odds move. It becomes easier with practice.
