Account
To update your profile on si6x, log in and go to Account Settings. You can update your name under the "Personal Information" or "Profile" section — just make sure the name matches what's on the NID you submitted for KYC, otherwise you may run into issues with withdrawals.
Changing your mobile number is a slightly different process since it's tied to your core account identity. An OTP is sent to your old number for verification, then another OTP is sent to the new number — once both are confirmed, the number is updated. If you no longer have access to your old number, contact support directly and verify your identity with your NID and a selfie — this is usually resolved within 24 hours. One important tip: keeping your bKash or Nagad number the same as your registered account number makes withdrawals smoother.
Account
You must be at least 18 years old to register and use any service on si6x. This isn't just a formality — it's one of si6x's strictest policies.
Date of birth is collected at registration, and age is verified through NID checks during the KYC process. Any account registered by someone under 18, or opened using false information, will be permanently closed and any deposited funds will not be refunded. If a family member suspects that a minor is using si6x, contact support@si6x.best immediately — si6x will act swiftly.
Bonus
To access daily check-in and free spin offers on si6x, log in first. Once logged in, active offers will appear on the home page or under the "Promotions" section — simply click the "Check-In" or "Collect Free Spins" button to register your participation.
For check-in bonuses, rewards typically grow with consecutive daily logins — for example, ৳50 on day one, ৳150 on day three, and up to ৳500 on day seven. Missing a day resets the streak and you'll need to start over. Free spins may be restricted to specific games or slots. All terms are clearly stated in each offer's description. To view the latest active offers On the Promotions page Go.
Betting
Placing an accumulator on si6x is straightforward. After adding a selection from one match to your betting slip, simply add a selection from another match to the same slip — the "Accumulator" mode activates automatically.
An accumulator can hold a minimum of 2 and a maximum of 20 selections. Each selection's odds are multiplied together to form the total odds — so if any one selection loses, the entire bet is lost. For example, if three selections have odds of 1.80, 2.00, and 1.50, the total odds are 1.80 × 2.00 × 1.50 = 5.40. A ৳100 bet would return ৳540 if all selections win. The total odds and potential winnings are shown on the slip before you place your bet. Minimum bet starts from ৳10. Accumulator restrictions may apply on certain markets — the system will notify you if that's the case.
VIP
si6x's VIP program has five tiers — Bronze, Silver, Gold, Platinum, and Diamond. Every bet you place earns loyalty points, and your tier is determined by your total points accumulated.
The benefits vary significantly across tiers. Moving from Bronze to Silver requires 5,000 points, unlocking higher reload bonuses and priority support. At Gold (20,000 points), you get a dedicated account manager, faster withdrawal processing, and monthly cashback. Platinum and Diamond members enjoy higher withdrawal limits, invitations to exclusive events, and custom bonus offers. You can always check your current points and progress toward the next tier in the VIP section of your account.
Tournament
Joining a si6x leaderboard tournament is usually automatic — no separate registration needed. Simply place a bet of the minimum required amount in the specified market during the tournament period and points will start accumulating.
Rankings are typically based on total net winnings, highest single win, or total bet amount in specific markets — the rules vary by tournament and are detailed on the "Sports Events" page. Prizes are generally credited to your account within 24 hours of the tournament ending. Top 10 prizes can range from ৳500 to ৳50,000 depending on the event. To view currently active tournaments On the Sports Events page Go.
Payment
Under normal circumstances, your si6x account balance is updated within 2 to 5 minutes of a bKash or Nagad deposit. If it still hasn't appeared after 10 minutes, please check the following first:
1. Whether your bKash or Nagad app shows a success message in your transaction history. If it doesn't say "Successful," the money was not deducted — please try again.
2. Whether you sent the deposit to the correct merchant number on the si6x deposit form. If sent to the wrong number, it will not be credited to your si6x account.
3. Have your payment reference number (Transaction ID) ready.
If bKash shows "Successful" but the amount hasn't appeared in si6x, go to live chat immediately and provide your bKash Transaction ID. The si6x support team will manually verify and credit your balance within 30 minutes. If you've been charged twice, don't worry — the duplicate charge will be refunded once the reference is checked.
