Deposits and Withdrawals
3666d currently supports the most widely used mobile banking services in Bangladesh: bKash, Nagad, Rocket, and Upay. All four methods can be used for both deposits and withdrawals. The minimum deposit amount for each method is ৳300.
Funds deposited via bKash are usually added to your 3666d account within a few minutes. If the amount is correct and the network is normal, the credit is nearly instant. If there is a delay, contact live chat with your slip or transaction ID.
The minimum withdrawal amount at 3666d is ৳1,000. Once a withdrawal request is approved, the money usually reaches your bKash, Nagad, Rocket, or Upay within 10 to 45 minutes. There may be a slight delay during peak hours.
3666d does not deduct any extra charges of its own for deposits or withdrawals. However, bKash, Nagad, or other mobile banking services may apply their own transaction charges, which depend on the payment provider's policy. It is wise to check the charges in the relevant app before making a transaction.
Log in to 3666d, click on the "Deposit" option, and select Nagad as the payment method. Following the instructions shown, send the amount to the designated number from your Nagad app. Enter the amount and reference number correctly — starting from a minimum of ৳300.
Common reasons for a rejected withdrawal include: incomplete account verification, unmet bonus wagering requirements, or the amount being below the minimum. Contacting live chat will help you quickly find out the reason and resolve the issue. Our support team is available 24/7 in Bangla.

Bonuses and Promotions
When you open a new account and make your first deposit of at least ৳300, 3666d automatically gives you a 150% welcome bonus — up to a maximum of ৳20,000. That means if you deposit ৳10,000 you get ৳15,000 as a bonus, bringing your total balance to ৳25,000. The bonus is added to your account automatically.
The wagering requirement for 3666d's welcome bonus is 15 times (15x). This means you need to complete bets totalling 15 times the bonus amount before you can withdraw it. Example: if you receive a ৳5,000 bonus, you need to complete ৳75,000 in bets for the bonus to become withdrawable.
3666d has five VIP levels: Bronze, Silver, Gold, Platinum and Diamond. By playing regularly, you can gradually move up to higher levels. The weekly cashback increases at each level — Bronze offers 0.2%, Silver 0.3%, Gold 0.5%, Platinum 0.6%, and Diamond up to 0.8% weekly cashback.
Each week, depending on your VIP level, a set percentage of your net losses is returned to you as cashback. Cashback is added to your account at a set time each week. This amount can be used directly for betting, which works as extra protection for regular players.
