An accumulator (also called a "multi bet" or "combo") means betting on two or more matches at once — you need to win all of them to get paid. Lose just one and the whole bet is gone, but win them all and your odds multiply, making the payout much larger.
Steps to place an accumulator bet on 666db:
- Go to the Sports section, select a match, and click on the odds — it will be added to your bet slip
- Keep adding more matches one by one (up to 15–20 selections)
- Select the "Accumulator" or "Multi" option on your bet slip
- Enter your stake amount and review your potential winnings before confirming
Example: Three matches with odds 2.0 + 1.8 + 2.5 — combined multiplier: 2.0 × 1.8 × 2.5 = 9.0. A ৳100 bet returns ৳900 if all legs win.
666db lets you bet on cricket, football, tennis, badminton, kabaddi, and 30+ other sports. Football sees the most action — World Cup, Premier League, Champions League, and more.
Popular Bet Types:
- Match Result (1X2): Will the home side win, will it be a draw, or will the away side win? Pick one of the three.
- Over/Under Goals: Will there be more or fewer goals than the set number? It's the simplest bet you can place.
- In-Play Bet: Bet on live odds while the match is in progress — the most thrilling way to bet.
- Handicap Bet: Bet on the underdog with a goal handicap advantage.
To get started: Log in → Go to Sports → Choose your league or match → Click on the odds → Enter your stake in the bet slip and confirm.
666db displays odds in decimal format — the easiest format to understand. The calculation is straightforward:
- Payout = Stake × Odds
- Example: Odds 2.50, Bet ৳100 → Win ৳250 (including your original ৳100)
- Odds 1.80, Bet ৳200 → Win ৳360
- Odds 3.00, Bet ৳500 → Win ৳1,500
The higher the odds, the bigger the potential win — but the less likely you are to win. Odds start from 1.01, which means a near-certain outcome but a very small return.
The bet slip automatically displays the odds and potential winnings — no manual calculations needed.
