3666 det Bet — A Complete Introduction to Online Betting in Bangladesh
From logging in to choosing markets, reading odds, and managing your budget — this guide will help you start betting on the 3666 det Bet platform.
Log In and Fund Your Account
Betting starts with an active account. The full process is explained step by step below.
Log In
Go to the 3666 det Login page and enter your username and password. If you are new, register — the entire form can be filled out in Bengali.
Go to Your Wallet
After logging in, go to the Wallet page and select the deposit option. The minimum deposit is ৳500.
Choose a Payment Method
Deposit using bKash, Nagad, Rocket, or bank transfer — whichever is convenient for you.
Confirm Your Balance
Once the deposit is complete, your wallet balance will be updated. You can then place a bet on any market right away.
A Little More About Payment Methods
At 3666 det, you can deposit instantly via bKash, Nagad, and Rocket. For bank transfers, accounts at major banks such as Dutch-Bangla, BRAC, or Islami Bank can be used. Withdrawal requests are generally processed within 5 to 30 minutes, and the minimum withdrawal amount is also ৳500.
Always use the Wallet section to track your betting history and balance — all deposits and withdrawals are recorded there in one place.
Find a Market and Read the Odds
A betting market is a list of outcomes you can bet on. Odds show how much you will receive if that outcome occurs. 3666 det Bet offers markets across various events from cricket to football.
Decimal Odds
This is the simplest format. Multiply the odds figure by your stake to get the total return. Example: a ৳1,000 stake at decimal 3.00 means a total return of ৳3,000 (profit ৳2,000 + stake ৳1,000).
Fractional and American Odds
The same price in three formats: decimal 3.00 = fractional 2/1 = American +200. 3666 det Bet generally displays decimal format, which is more familiar to Bangladeshi bettors.
Team A to Win, stake ৳1,000:
Decimal 3.00 = Fractional 2/1 = American +200.
If it wins, total return is ৳3,000 (profit ৳2,000 + stake ৳1,000); if it loses, ৳1,000 is gone.
Team B to Win: Decimal 1.50 = Fractional 1/2 = American -200. A ৳1,000 stake returns a total of ৳1,500 if it wins (profit ৳500).
For detailed information on betting markets such as cricket match winner, T20 top batter, or BPL match over/under, visit the Cricket Betting page — it covers live markets and different types of cricket bets separately.
The Bet Slip — Single and Multi Bets
Clicking on a selection in a market adds it to the bet slip. Enter your stake there and the potential return is shown immediately.
Single Bet
A bet on one selection only. The return is straightforward: stake × odds. An example —
There are no draws in limited-overs matches.
Team A odds 1.65, Team B odds 2.30.
A ৳500 stake on Team B returns a total of ৳1,150 if Team B wins (profit ৳650); if Team A wins, ৳500 is lost.
Multi Bet
Multiple selections are combined in one bet slip. You receive the full return only if all selections win — if even one loses, the entire bet is lost.
3 selections: Decimal 1.40 × 1.70 × 1.90 = 4.52 (combined odds).
With a ৳100 stake, if all win the total return is ৳452; if even one loses, the full ৳100 is gone.
The potential return is calculated and displayed on the bet slip as soon as you enter your stake.
BACK Team A at decimal 2.50, stake ৳500: if Team A wins, profit before commission is ৳750; if not, ৳500 is lost.
LAY Team A, bettor's stake ৳500: your liability is ৳750 (৳500 × 1.50); if Team A does not win, profit before commission is ৳500; if it wins, you pay ৳750.

Set a Budget and Limits Before Betting
Betting is entertainment — not a guarantee of profit. Before you start, set some rules for yourself so that it stays entertainment.
Daily Budget
Decide in advance how much you will spend on betting each day. Once that amount is used up, stop betting for the day.
Single Bet Limit
It is better not to put a large portion of your total budget on one bet. Betting smaller stakes across more markets reduces risk.
Time Limits
It is better not to bet for long stretches at a time. Bet for a set period and take breaks.
Self-Exclusion Option
If needed, you can temporarily pause your account. Read the Responsible Gaming guidelines for more details.
