  • Rocket — Minimum ৳200 (10 minutes)
  • Bank Transfer — Minimum ৳1,000 (1–4 hours)
No hidden charges on any transactions.

The minimum deposit via bKash and Nagad is ৳100. The daily maximum depends on your account level — typically between ৳1,00,000 and ৳5,00,000. VIP members enjoy even higher limits.

Deposits via bKash and Nagad are typically instant — arriving within 5 minutes at most. Rocket may take 10–15 minutes, and Bank Transfer can take 1–4 hours. If your deposit is delayed by more than 30 minutes, contact support with your transaction ID.

Withdrawals for verified (KYC-completed) accounts are typically processed within 5–15 minutes. Unverified accounts may take up to 24 hours. We strongly recommend completing your KYC in advance.

3666bet does not charge any withdrawal fees. However, mobile banking operators (bKash/Nagad) may apply their own cash-out charges — this is outside 3666bet's control. To receive the maximum amount, use direct Bank Transfer.

To complete KYC, log in to your account → Profile → Identity Verification → upload a photo of your NID or passport. Verification is usually completed within 24 hours. Large withdrawals cannot be processed without a completed KYC.

Yes! With an Accumulator (or Parlay) bet, you can combine multiple selections into a single wager. If all selections win, the payout is significantly larger — but the risk is higher too, as a single wrong pick will cost you the entire bet.

The minimum bet at 3666bet is generally ৳10, though this may vary by sport and market. The maximum bet depends on your account level and the specific market you are betting on.

Once a match concludes and the bet is settled, winnings are instantly credited to your balance — usually within 15–30 minutes of the final whistle. Live bet settlements may be even faster.
