Detailed FAQ
Verification & Documents
The most common reasons for rejection are blurry images, expired documents, or a name mismatch. The support team will notify you of the reason by email or live chat. Reapply with clear, correct images. If there is a name or date discrepancy, resolve that first, then resubmit.
The National ID Card (NID) is the most commonly used document. A valid passport or driving license is also accepted. Clear photos of both the front and back of the document are required. All information on the document must be fully readable — any covered or cut-off sections will not be accepted.
Yes. All uploaded documents are stored securely using SSL encryption. This information is not shared with any third party. It is used only for the verification process in accordance with 87bk's privacy policy.
Yes, this is mandatory. The name registered on your account and the name on your bKash, Nagad, or Rocket account must be exactly the same. The same rule applies to bank transfers. A name mismatch may cause your withdrawal request to be held.
Account Security
Use a password of at least 12 characters that combines uppercase letters, lowercase letters, numbers, and special characters (!, @, #, etc.). Avoid your own name, date of birth, or simple words. Do not use your 87bk account password on any other site, and change it at regular intervals.
Your OTP (One-Time Password) and mobile banking PIN are completely personal. No 87bk staff member or support agent will ever ask for this information. If anyone does ask, it is an attempt at fraud. Sharing this information can put both your account and your mobile wallet at risk.
SSL (Secure Socket Layer) encryption is used at every level of connection on the 87bk site. This means your login details, payment information, and personal data are protected in transit. If you see a padlock icon in your browser's address bar, your connection is secure.
If you see an unfamiliar transaction or login activity, change your password immediately and report it via live chat or at [email protected]. The support team will review your account activity promptly and, if necessary, take steps to temporarily secure it.
How to Deposit
87bk itself does not charge any deposit fee. However, mobile banking services such as bKash, Nagad, or Rocket may apply a small charge on send money or payment transactions according to their own terms. For bank transfers, fees may vary by bank — check with your bank for details on those charges.
After logging in to 87bk, go to the deposit option and select bKash. Make the payment to the designated 87bk merchant number and save your transaction ID. Once the process is complete, the balance will be added to your account. If you have any issues, contact live chat with your transaction ID.
Yes, the Nagad deposit process is mostly the same as bKash. Select Nagad on the deposit page, follow the instructions, and confirm the payment. Both the Nagad send money and payment options can be used. Always keep your transaction reference after the payment.
The minimum deposit for every method is just ৳100. That means whether you use bKash, Nagad, Rocket, Upay, or bank transfer, you can get started with just one hundred taka. The minimum withdrawal amount is ৳1,000.
Support Questions
Before getting in touch, have your registered email or phone number, a detailed description of the issue, and any relevant transaction IDs or screenshots ready. This helps the support team understand the situation quickly and resolve it faster.
87bk's support is active seven days a week, 24 hours a day. Whether it's morning, night, or a holiday, you can reach out via live chat or email at any time and a capable agent will assist you.
There are two main contact channels. The first is direct live chat — you will find the chat window as soon as you enter the site. The second is email — send a message to [email protected]. For urgent matters, live chat is the fastest option, while email is more effective for detailed issues.
Yes, the 87bk support team provides assistance in both Bengali and English. Players from Bangladesh can ask questions in their own language without any difficulty. There is no language barrier — reach out whichever way feels most comfortable.
Slot Games
Free spins are extra spin opportunities that do not require you to wager from your own balance. They are usually awarded through bonus offers, special promotions, or by triggering scatter symbols within a game. Winnings from free spins may be subject to wagering requirements — read the terms of each offer separately.
Many slot games have a demo or fun mode where you can try the game with a virtual balance. This is a good way to understand the game mechanics and features. However, any winnings from demo mode are not added to your real account.
A progressive jackpot is a prize pool where a small portion of every bet by every player is added continuously. The more people play, the larger the pool grows. When someone wins the jackpot, the pool resets to zero and starts growing again. This is why these jackpots sometimes reach very large amounts.
RTP, or Return to Player, is a measure of what percentage of total bets a game theoretically returns over the long term. It is a statistical average — results can vary in each session. A higher RTP means a better long-term return rate, but it is not a guarantee of individual wins.
Volatility refers to how frequently and how large the rewards a game pays out. Low-volatility games pay out frequently but in smaller amounts, which suits longer play sessions. High-volatility games pay out less often but the rewards are larger when they do hit. Choosing the right volatility level based on your preference and budget is a sensible approach.
