FAQ
Answers to the most frequently asked questions at gtb99
From making deposits to playing on mobile — find simple, clear answers to all the important questions Bangladeshi players have.
Whether you are new to gtb99 or a returning player, questions come up every day. Below, the most common ones are organized into five categories: Deposits, Slot Games, Verification & Documents, Contact & Support, and Mobile Use. If you cannot find an answer to your question, reach out via our 24/7 live chat or email.
Deposits
Log in to gtb99 and go to the deposit page, then select Nagad as your payment method. Send the specified amount from your Nagad app to the number provided. Save the transaction ID and paste it into the form. The minimum deposit amount is ৳100. If the number and amount are correct, your balance will be updated instantly.
Yes, a few things are important to keep in mind. When paying via bKash, use the "Send Money" option — not "Payment". Use the number shown on the deposit page and enter your username in the reference or note field. Once the transaction is complete, submit the ID you receive on the site. Using the same bKash number each time makes the process even smoother.
There are currently four deposit methods: bKash, Nagad, Rocket, and bank transfer (Sonali Bank, Dutch-Bangla Bank, and other major banks). The minimum deposit amount is ৳100 for each method. There are no separate method-based limits or extra conditions — the same rules apply across all methods.
gtb99 does not charge any processing fee on deposits. However, your mobile financial service (bKash / Nagad / Rocket) may deduct their own service charge — this depends entirely on that provider's policy. Bank transfers may also carry applicable bank charges separately.
Wait a few minutes first, as there can occasionally be a short delay due to network congestion. If your balance still does not appear, take the transaction ID and a screenshot from the Rocket app and contact us via live chat. Providing accurate information allows the support team to resolve the issue quickly.
Slot Games
Free spins are a special slot game feature that grants you extra spins without spending your own balance. They are usually triggered when a specific symbol lands a certain number of times at once. Winnings from free spins are generally added as a bonus, which can be withdrawn after meeting the wagering requirements.
Slots that allow a low minimum bet per spin are the most suitable for players on a tight budget. Low-volatility slots pay out small wins frequently, giving you more playing time. High-volatility slots can bring larger rewards but also have longer dry spells in between. Staying within your own limits is the wisest approach.
Yes, many slot games at gtb99 have a demo mode available. In this mode you play with virtual credits, so there is no risk to real money. Demo mode is a great way for new players to get a feel for a game or test out its features. However, winnings from demo mode cannot be withdrawn.
RTP (Return to Player) is a theoretical percentage that indicates how much of the total bets placed on a slot it returns to players over the long term. For example, a higher RTP means the game has a greater average chance of paying back more. However, this is a long-term average, so results can vary from session to session — RTP is a statistic, not a guarantee.
In a progressive jackpot, a small portion of every spin from every player is added to the jackpot pool. The more people play, the larger the prize grows. Once someone wins the jackpot, the pool resets and starts again from a set minimum value. Players across multiple tables or networks contribute to this type of game simultaneously.
Verification & Documents
Yes, this is very important. The name registered on your gtb99 account must exactly match the ownership name on the bKash, Nagad, or Rocket number you are using. For bank transfers, the bank account name must also match. If the names do not match, your withdrawal may be held or your verification may be rejected.
Read the rejection email or message carefully, as it will state the reason. Common reasons include blurry images, cropped documents, or a name mismatch. Correct the issue and resubmit clear, complete documents. If needed, contact us via live chat and the support team will tell you exactly where the problem lies.
Verification is typically requested before large withdrawals, when suspicious activity is detected, or when updating account information. It may also be required on a new account's first withdrawal. This is a standard process to ensure the security of your account.
gtb99 stores all documents on secure servers using SSL encryption. This information is not shared with third parties and is used solely for identity verification purposes. You can read the site's privacy policy for more details.

Absolutely. The gtb99 support team is able to assist in both Bengali and English. If you write in Bengali via live chat or email, the support representative will reply in Bengali — you are not required to write in English.
For immediate issues, live chat is the most effective option since you can communicate in real time. Email is generally better suited for complex matters, submitting documents, or keeping a written record. For urgent problems, prioritize live chat.
