Finding markets and understanding odds
A market is the event or outcome you want to bet on. When you enter the sports section at 3666 bdt, you will see different categories by sport type. After selecting a match, there is a number next to each team — that is the odds.
Decimal odds
The simplest format. Multiply your stake by the odds to get the total return. For example, ৳200 × 2.50 = ৳500.
Most commonFractional odds
Written as a fraction, such as 3/2. This means ৳3 profit for every ৳2 staked. Total return = profit + stake.
British formatAmerican odds
Shown with a plus (+) or minus (−) sign. +150 means ৳150 profit on a ৳100 bet; −200 means you need to bet ৳200 to win ৳100 profit.
American formatA comparison example across all three formats
The table below shows the same bet in all three formats. A ৳200 stake on Team A to win:
| Format | Odds | Stake | Total return | Profit |
|---|---|---|---|---|
| Decimal | 2.50 | ৳200 | ৳500 | ৳300 |
| Fractional | 3/2 | ৳200 | ৳500 | ৳300 |
| American | +150 | ৳200 | ৳500 | ৳300 |
All three formats give the same result — only the way they are written differs. If the bet wins, you get back ৳500 (৳300 profit + ৳200 stake); if it loses, you lose ৳200. If Team B is the favourite, the odds might be decimal 1.50 = fractional 1/2 = American −200; in that case a ৳200 stake gives a total return of ৳300 (profit ৳100).
Bet slip — single and multi bets
Clicking on any outcome automatically adds it to the bet slip. Keeping just one selection makes it a single bet. Enter the amount in the stake field and the potential return is shown instantly.
Adding more than one selection creates a multi bet (or accumulator). All the odds are multiplied together to form combined odds, giving the chance of a larger return from a single bet — but if any one selection loses, the entire bet loses.
Cricket match winner example
In a limited-overs match: Team A odds 1.45, Team B odds 2.75. Placing ৳500 on Team B — if Team B wins you get back ৳1,375 in total (৳875 profit). If Team A wins, you lose ৳500.
Team A and Team B are hypothetical examples — these are not live odds or a guarantee of winning.
Multi bet example (3 selections)
If three selections have decimal odds of 1.60, 1.80, and 1.90, the combined odds are: 1.60 × 1.80 × 1.90 = 5.47 (approximately). A ৳100 stake returns ৳547 — but only if all three selections win. If even one loses, the full ৳100 is lost.
A multi bet offers greater potential profit, but also carries greater risk.
This return applies only if all three selections win.
Placing bets on sports and casino games
The sports betting section has markets for cricket, football, and other sports. Markets are most active during BPL, IPL, and T20 World Cup tournaments. Both pre-match bets before a game starts and in-play bets during a game are available at 3666 bdt. For cricket fans in Bangladesh, detailed information is available on the 3666 bdt cricket betting page.
In the casino section you will find slots, live casino, baccarat, roulette, and fishing games. There is no bet slip here — stakes or chips are selected within the game itself. In slot games, clicking the spin button completes the bet. Visit the casino page to see the full game list at 3666 bdt Casino.
Betting in a live betting exchange format is also possible. For example: backing Team A at decimal odds of 2.50 with a ৳1,000 stake — if Team A wins you make ৳1,500 profit (minus commission); if they do not win, you lose ৳1,000. With a LAY bet, if Team A does not win you receive ৳1,000, but if they do win you must pay out ৳1,500 (your liability is ৳1,500).
Bet history — open and settled bets
After placing a bet, go to the "Bet History" or "My Bets" section of your account to check its status. All bets are shown in two parts:
Open bets
Bets where the event has not yet finished appear here. The market, odds, stake, and potential return are all clearly shown.
Settled bets
Once an event ends, the bet is settled and the result is recorded. For winning bets, the return is added directly to your balance.
The history can be filtered by date and event. You can calculate your total stake and profit or loss for a given period from here, which helps with budget management.
Set your budget and limits in advance
Betting is a form of entertainment — only a set portion of what is left over after essential household expenses should go toward betting. Before you start, decide your limit for the day or for the week.
- Set a fixed weekly or monthly budget and stop when it is reached — regardless of results.
- Check your bet history regularly. At the end of each week, review your total stakes and returns.
- Avoid the urge to place larger bets to recover losses — this makes the situation worse.
- Also keep track of how much time you spend betting each day. Make time for rest and family.
- Betting is only for those aged 21 and above. Accounts should not be used by minors.
- To learn about responsible gambling rules and how to keep yourself safe, read the responsible gaming guide.
