Account and Registration
To register at big999, you need an active mobile number and a password. You will also need to provide your name and date of birth. You must be 21 years of age or older for age verification. Provide accurate information, as identity verification is required at the time of withdrawal.
Only one account per person is allowed. Opening multiple accounts with the same mobile number or identity document is prohibited. If multiple accounts are found, big999 reserves the right to suspend any of those accounts, and related bonuses may be cancelled.
Click the "Forgot Password?" option on the big999 login page. Enter your registered mobile number and use the OTP code you receive to set a new password. If you have trouble, contact our 24/7 live chat — the team will assist you in Bengali.
In most cases, identity verification is completed quickly. Submitting a clear photo of your national ID card or passport makes the process smoother. Withdrawals may be limited until verification is complete. Contact the support team if you run into any issues.
Deposits and Withdrawals
big999 currently supports deposits and withdrawals through three mobile banking methods: bKash, Nagad, and Rocket. These are the most popular payment methods in Bangladesh, and the entire transaction can be completed from your mobile.
Deposits made via bKash, Nagad, or Rocket are usually credited to your big999 account instantly or within a few minutes. If there is a delay for any reason, save your payment reference number and let us know via live chat.
The minimum deposit amount at big999 is ৳500, and the minimum withdrawal amount is also ৳500. This limit applies to all payment methods. Transactions below this amount will be rejected by the system.
Once a withdrawal request from big999 is approved, the funds generally arrive in your bKash, Nagad, or Rocket account within 1 hour. If your account verification is already complete, this process is even faster.
big999 does not charge any transaction fees on its end. However, bKash, Nagad, or Rocket may apply their own service charges. It is a good idea to check your mobile banking provider's fee structure before making a transaction.
First, check the SMS from bKash or Nagad to confirm whether the transaction was successful. If it was successful but has not been added to your big999 account after more than 30 minutes, contact our support team via live chat with your transaction ID. The issue will be resolved promptly.
Games and How to Play
Yes, big999 offers betting on BPL (Bangladesh Premier League), T20 World Cup, IPL, and various other international cricket tournaments. Both pre-match and live betting options are available. Visit the cricket page for more details on cricket betting.
RTP (Return to Player) is the average percentage of total bets that is returned to players over the long term in a game. For example, a 95% RTP means that on average ৳95 is returned for every ৳100 wagered — but this is an average across millions of rounds, not the result of a single session. A higher RTP is generally better for players.
All games at big999 are powered by software from reputable game providers such as PG Soft, Pragmatic Play, JILI, Spribe, and Ezugi. These games use RNG (Random Number Generator) technology, which keeps results completely random. The platform follows fair play principles.
