👤 Account & Registration
How do I create a sis66 account in Bangladesh?
Creating a sis66 account takes under two minutes on any Android or iOS device. Visit sis66.vip, tap the register button, enter your mobile number, choose a strong password, and confirm your date of birth. You must be aged 21 or above to register. Once your number is verified via OTP, your account is active and ready for your first deposit.
What documents do I need for KYC verification on sis66?
sis66 accepts the Bangladesh National ID Card (NID) or a valid passport for identity verification. You may also be asked to submit a selfie holding your ID document. KYC is required before processing your first withdrawal and is typically reviewed within 24 hours of submission. Accounts that pass KYC have higher withdrawal limits and priority support.
I forgot my sis66 password — how do I reset it?
On the sis66 login page, tap 'Forgot Password' and enter your registered mobile number. You will receive an OTP via SMS. Enter the OTP, then set a new password. The entire process takes about 90 seconds. If your registered number is no longer active, contact [email protected] with proof of identity and our team will verify your account manually.
Can I have more than one sis66 account?
No — sis66 strictly enforces a one-account-per-player policy. Registering duplicate accounts is a violation of our Terms & Conditions and may result in permanent suspension of all associated accounts and forfeiture of any balances. If you have accidentally created a duplicate, contact support immediately to have the extra account closed before it is flagged by our systems.
How do I close my sis66 account permanently?
To permanently close your sis66 account, email [email protected] with the subject 'Account Closure Request' and include your registered mobile number. Any remaining real-money balance will be returned to your registered payment method within 3 to 5 business days. If your reason for closing relates to problem gambling, we strongly recommend activating self-exclusion instead — this can be done instantly from your account settings.
💳 Deposits & Withdrawals
How long does a bKash deposit take to appear on sis66?
bKash deposits on sis66 are credited instantly in the vast majority of cases — typically within 30 seconds of your bKash transaction being confirmed. If your deposit has not appeared after 5 minutes, check that you used the correct sis66 merchant number and entered the exact reference code. For unresolved delays, contact [email protected] with your bKash transaction ID.
What is the minimum deposit amount on sis66?
The minimum deposit on sis66 is ৳200 for bKash, Nagad, and Rocket. For Upay the minimum is also ৳200. Bank transfer minimums may be higher depending on your bank's own transfer limits — typically ৳500 or more. There is no maximum deposit cap, although very large transactions may trigger a routine account review as part of our security procedures.
How long do withdrawals take on sis66, and what is the minimum?
The minimum withdrawal on sis66 is ৳500. bKash and Nagad withdrawals are typically processed within 1 to 3 hours during business hours (10:00–24:00 BST). Rocket and Upay withdrawals follow a similar timeline. Bank transfers may take 1 to 3 business days depending on your bank. All withdrawals require completed KYC verification before they can be processed.
Does sis66 charge fees on deposits or withdrawals?
sis66 does not charge any platform fees on deposits or withdrawals. Your full deposited amount is credited to your account, and your full withdrawal amount is sent to your payment method. Note that your mobile banking provider (bKash, Nagad, Rocket, etc.) may apply their own standard transaction charges — these are set by the provider and are outside sis66's control.
Can I withdraw to a different bKash number than the one I deposited from?
For security reasons, sis66 processes withdrawals to the same payment method and account number used for your most recent deposit. This policy protects players from unauthorised withdrawal attempts. If you need to update your registered payment method — for example, if you have changed your bKash number — contact [email protected] with your ID document for verification before requesting a withdrawal.
🎮 Games & Gameplay
What cricket betting markets does sis66 offer for BPL and IPL matches?
sis66 offers a wide range of cricket betting markets for BPL, IPL, T20 World Cup, and Bangladesh Tigers matches, including match winner, top batsman, top bowler, total runs over/under, first wicket method, powerplay runs, and live in-play betting. Odds are updated in real time. Markets open approximately 24 hours before the scheduled match start time and close at the first ball.
Is sis66 safe to play on a mobile phone in Bangladesh?
Yes — sis66 is fully optimised for mobile play on Android and iOS devices and uses SSL/TLS encryption on all connections, meaning your personal data and financial transactions are protected. The platform does not require an app download; it runs directly in your mobile browser at sis66.vip. Game outcomes are determined by certified RNG systems to ensure fairness.
What is RTP and what RTP can I expect on sis66 slots?
RTP (Return to Player) is the percentage of all wagered money that a slot machine statistically pays back to players over time. A slot with 96% RTP returns ৳96 for every ৳100 wagered on average. sis66 hosts slots from leading providers including Pragmatic Play and NetEnt, most of which carry RTPs between 94% and 97%. Specific RTP values for individual games are shown in the game's information panel.
Can I play sis66 live casino games on my phone?
Yes — all sis66 live casino games, including live Baccarat, live Roulette, live Blackjack, and Andar Bahar with live dealers, are fully playable on Android and iOS smartphones. The live streams are optimised for 4G and Wi-Fi connections. For the best experience, a stable internet connection is recommended, though the streams automatically adjust quality for lower-bandwidth connections.
🎁 Bonuses & Promotions
What welcome bonus does sis66 offer to new players in Bangladesh?
sis66 offers a welcome bonus to new Bangladeshi players on their first deposit. The current offer is detailed on the promotions section of the site when you log in. Welcome bonuses at sis66 are subject to wagering requirements before the bonus or any winnings derived from it can be withdrawn. Always check the specific terms attached to each promotion before claiming.
What does wagering requirement mean, and how do I clear it on sis66?
A wagering requirement (also called rollover) is the number of times you must bet your bonus amount before you can withdraw any winnings. For example, a ৳1,000 bonus with a 20x wagering requirement means you must place ৳20,000 in total bets before withdrawing. On sis66, bets on slots typically count 100% towards clearing the requirement, while live casino games may count at a lower rate — check the specific promotion's terms for exact contribution rates.
Do sis66 bonuses expire if I do not use them?
Yes — most sis66 bonuses carry an expiry period, typically 7 to 30 days from the date of issue, within which you must meet the wagering requirement. If the wagering requirement is not met before expiry, the bonus amount and any associated winnings are forfeited. The remaining balance of your real-money funds is unaffected. Expiry dates are always shown in the bonus terms when you claim.
Are there reload bonuses or loyalty rewards for existing sis66 players?
Yes — sis66 runs regular reload bonuses, seasonal promotions tied to events like BPL, IPL, Eid, and Pohela Boishakh, as well as a VIP loyalty programme for high-volume players. VIP members receive faster withdrawals, higher limits, dedicated account managers, and exclusive bonus offers. The full current promotions list is visible after you log in to your sis66 account.
