Customer Support
Yes, gb99k's support team can help in both Bengali and English. If you write your question in Bengali, you'll get a reply in Bengali right away. You can reach out about any issue without worrying about the language.
gb99k offers two support channels — live chat and email. You can start a live chat directly from any page on the site. To reach out by email, the address is [email protected]. You can write in Bengali through both channels.
Before reaching out via chat or email, have your registered username or mobile number, a brief description of the issue, and your transaction reference number (if needed) ready. This helps the support agent identify and resolve your issue faster.
Absolutely. gb99k's live chat support is active 24 hours a day, 7 days a week — nights, early mornings, and holidays included. You can start a chat at any time according to Bangladesh Standard Time (BST, UTC+6).
Slots & Jackpots
If your budget is limited, go for slots with smaller coin sizes or low-volatility games — these let you play longer with small bets and tend to pay out more frequently. High-volatility slots can offer bigger rewards but may also come with long dry spells. Choose based on what fits your budget.
Free spins generally come in two ways — when specific symbols line up within the game, or through special offers on the platform. With free spins, you can spin the reels without spending your own balance. Winnings are usually credited as a bonus and may require meeting certain conditions before withdrawal.
RTP stands for Return to Player — it is a theoretical percentage indicating how much of the total bets a slot game is expected to return to players over the long term. For example, a higher RTP means comparatively more is returned. However, RTP is a long-term average — results in a single session can vary.
In a progressive jackpot, a small portion of every bet is added to a pool. The more players bet, the larger the prize grows. When someone wins the jackpot, the pool resets to zero and begins accumulating again. It can grow much larger than a fixed-amount jackpot.
Deposits
The minimum deposit amount at gb99k is ৳300 for every payment method. The same rule applies across all four methods — bKash, Nagad, Rocket, and Upay. Getting started with a small budget is easy.
gb99k supports four popular mobile payment methods — bKash, Nagad, Rocket, and Upay. Among these, Rocket is the mobile wallet service from Dutch-Bangla Bank. These methods are the most widely used in Bangladesh, making deposits very convenient.
Log in to your account, go to the deposit option, and select bKash. Send the payment from the bKash app to the number shown on screen. Save the transaction ID and enter the reference number in the designated field. The deposit will go through if the amount is ৳300 or more.
gb99k itself does not charge any deposit fee. However, your mobile wallet provider (bKash, Nagad, Rocket, or Upay) may apply their own service charge — this is governed by that payment method's own policy. Check the charge details in that app before making a payment.
In some cases it may take a little time. If the balance still hasn't appeared after waiting a few minutes, contact live chat with your wallet transaction ID and amount. The support team will verify and resolve it quickly.
Responsible Gaming
There are some signs that should prompt you to be careful — such as spending more than your set budget, returning to play in order to recover lost money, neglecting family or work for gaming, or playing with borrowed money. If you notice these signs, take a break and seek help if needed.
Online gaming and betting are for adults. Younger individuals do not have the same maturity for financial decision-making or the capacity to handle the psychological impact as adults do. For this reason, gb99k strictly does not allow anyone under 21 to open an account. Parents are urged to stay vigilant to protect their children.
Cooling-off is a feature that lets you take a break from playing for a set period. Self-exclusion allows for a longer break or closing your account. To activate either option, inform the support team via live chat or at [email protected]. The team will complete the process promptly.
Yes. You can set a deposit limit on a daily, weekly, or monthly basis. Once this limit is active, you will not be able to deposit more than the specified amount — it is an effective way to stay within budget. Let the support team know and they will help you set the limit.
For help with responsible gaming, first let gb99k's support team know. You should also speak with a mental health counsellor or a trusted family member. Acknowledging the problem is the first and most courageous step toward a solution.
Account & Login
Click the "Forgot password?" link on the login page. Enter your registered mobile number or email and a verification code will be sent to you. Use the code to create a new password. The entire process can be completed within a few minutes.
Yes, gb99k accounts are not tied to a specific device. Simply log in with your username and password from any smartphone or computer and you will see your previous balance and history. No additional verification is needed for a new device.
After logging in, go to account settings to update your personal information. In most cases you can make changes directly. If verification is required for security reasons, inform the support team via live chat or at [email protected] — they will help you update your details safely.
A one-account-per-person policy applies. Multiple accounts cannot be opened using the same mobile number or identity document. If two family members each have a different number and identity document, they may open separate accounts, but sharing the same details is not permitted.
First, clear your browser's cache and cookies and try again. Make sure your password is correct — reset it if needed. If the problem persists, contact live chat with your device model and browser name.
