Detailed Q&A

Registration & Account

To register on sis6s, you need a valid Bangladeshi mobile number, your full name, and a strong password. Registration is completely free and takes just a few minutes. You may be asked to provide a National ID card or passport later for account verification.

Each person may open only one account. Attempting to create multiple accounts using the same mobile number or ID document may result in all accounts being suspended. Multiple accounts for the same individual are strictly prohibited under sis6s terms and conditions.

You can play and deposit up to a limited amount without verification. However, account verification is required to make withdrawals. The verification process involves uploading a photo of your national ID or passport. Verification is usually completed within 24 hours.

Yes, but to change your mobile number you will need to contact the sis6s support team directly. Your identity will be verified before the number is updated. For security reasons, this change is not processed instantly.

Deposits & Payments

sis6s accepts all major mobile banking methods in Bangladesh — Mobile Banking, Nagad, Rocket, and Upay — as well as direct bank transfers. The minimum deposit is just BDT 200 across all methods. In most cases, deposits are credited to your account instantly.

Deposits via mobile banking (Mobile Banking, Nagad, Rocket) are typically credited within 1–5 minutes. Bank transfers may take up to 30 minutes. If your deposit hasn't been credited after 1 hour, contact support with your transaction ID.

sis6s does not charge any extra fees on deposits. However, your mobile banking provider may apply its own transaction fee. For Mobile Banking and Nagad, this is typically between 1% and 1.85%, charged by the payment provider.

Withdrawals & Cashing Out

Withdrawals are typically credited to your mobile banking account within 15 minutes to 2 hours of submitting a request. During peak hours or on weekends, it may take up to 24 hours. For first-time withdrawals, having a verified account speeds up the process.

The minimum withdrawal on sis6s is BDT 300. The maximum single withdrawal limit is BDT 50,000. Higher limits apply for VIP members. Multiple withdrawals in a single day are allowed, but the daily total limit cannot be exceeded.

Yes, but you must meet the wagering requirement before withdrawing bonus winnings. Typically, you need to wager 15–30 times the bonus amount to become eligible for withdrawal. Each bonus has its own terms and conditions, which are clearly stated at the time the bonus is issued.

Bonuses & Offers

When you open a new account and make your first deposit, the welcome bonus is credited automatically. You can receive up to 100% bonus on your first deposit. There is no need to claim it separately — it is added to your account automatically after the deposit.

Share your referral link. When a friend registers through that link and makes their first deposit, you receive a bonus. You may also earn a monthly commission as long as your referred friend remains active. See the sis6s promotions page for full details.

Active regular players receive 5%–15% cashback on their daily net losses. The higher your VIP tier, the higher the cashback rate. Cashback is automatically added to your balance the following morning.
