Registration FAQs

Common questions about platform credibility and account closure

sis6 is an internationally licensed online gaming platform. Being licensed means the platform operates under a regulatory authority, undergoes regular audits, and is held to strict standards. At sis6, member funds are held in a separate, protected account — completely segregated from the company's operating expenses — so your balance stays safe no matter what. All games on sis6 use third-party audited RNG, guaranteeing that outcomes are entirely random and cannot be manipulated. All transactions are protected by 256-bit SSL encryption, and your personal information is never sold to third parties. If you ever have an issue, our support team responds quickly in Bengali. In short, sis6 is not just a website — it's a responsible platform that believes in accountability to its members. Registering is completely safe.

There are two ways to temporarily or permanently close your sis6 account. The first is self-exclusion, which you can do on your own. Log in, go to "Account Settings" → "Responsible Gaming", and select self-exclusion. You can choose a period ranging from 7 days up to 6 months, or opt for permanent closure. Once activated, your login access will be blocked immediately and you will stop receiving promotional messages. The second option is through support — if you are unable to do it yourself, email support@sis6.xyz or reach out via live chat. The support team will handle it on your behalf. If you want to permanently close your account, withdraw any remaining balance first, then submit your closure request. Reactivating a closed account requires a mandatory waiting period, which is designed to prevent impulsive decisions. To learn more about Responsible Gaming Responsible Play View the page.
