A detailed guide for new members
Many people have questions before registering at si6x — "Why do I need to provide so much information?", "Is it safe?", "Will I actually get the bonus?" All of these are answered here, because si6x believes it's their responsibility to make sure new members are fully informed.
Your mobile number is required during registration because payments on si6x are made through bKash and Nagad. Registering with the same number streamlines the payment process — no need to manually match numbers later. Your date of birth is requested for age verification (18+), purely to protect our members.
Imran, a new member from Chattogram, shared: "I thought signing up would be a long process. But all it took was my mobile number, name, and a password — done in under 5 minutes." That's exactly the experience si6x aims to deliver for everyone.
Let's be clear about the Welcome Bonus. A 100% bonus on your first deposit means if you deposit ৳1,000, you get another ৳1,000 as a bonus — giving you ৳2,000 to start betting with. The bonus comes with a wagering requirement, meaning you need to place a certain amount in bets before you can withdraw it. This is not a hidden condition — all details are clearly stated on the bonus page.
Many people find KYC — or identity verification — to be a hassle. But it's actually your account's strongest safeguard. If someone gets hold of your number and tries to access your account, they won't be able to make any withdrawals without completing KYC — your funds stay protected. Your NID photos are stored securely on si6x's encrypted servers and are never directly accessible to anyone.
Once you register at si6x, you can immediately start betting on cricket, football, and other sports. Real-time in-play betting, a cash-out feature, and over a thousand markets — all in one account. Works smoothly through any mobile browser, no separate app download needed.
Take your password seriously. A lot of people go with something simple like "123456" or their date of birth — that's a bad idea. Mix in at least one uppercase letter, a few numbers, and a special character to make it much stronger. Never share your password with anyone — si6x support will never ask for it.
After registering, si6x's 24/7 Live Chat support is always there if you need help. Ask your question in Bengali and get a response within 3–5 minutes. Can't log in, not receiving OTP, or any other issue — the support team is ready to sort it out.
