Section 01
Account and Registration
To open an account at bigtk, you need an active mobile number, an email address, and a password. It is important to provide accurate information during registration, as it will be needed later for identity verification and withdrawals. All information is stored securely through SSL encryption.
bigtk is for users aged 21 and above only. Minors are not permitted to open an account. If age verification is requested, you will need to submit the required documents. This is an important part of responsible gaming.
No, one person may hold only one bigtk account. Attempting to open multiple accounts under the same name, mobile number, or device may result in all accounts being suspended and balances being forfeited. If you run into any issues, contact us via live chat.
Click the "Forgot your password?" option on the login page. Enter your registered mobile number or email, and an OTP or link will be sent to you. Follow the steps to set a new password. If you have trouble, email [email protected] or get help via live chat.
KYC (Know Your Customer) is the identity verification process. At bigtk, you may need to submit a national ID card or passport before large withdrawals or if suspicious activity is detected on your account. This ensures the security of your account and helps prevent fraud.
Section 02
Deposits and Withdrawals
Deposits from bKash, Nagad, or Rocket are generally instant — in most cases the funds are added to your bigtk wallet within a few minutes. Bank transfers may take a little longer. If there is a delay, take a screenshot of the transaction and report it via live chat.
The minimum deposit amount at bigtk is ৳500 for all payment methods. This applies to bKash, Nagad, Rocket, and bank transfers alike. Players with smaller budgets can get started easily.
bigtk itself does not charge any additional fees on deposits or withdrawals. However, bKash, Nagad, or your bank may deduct their own transaction fees in accordance with their own policies. Contact the relevant payment provider for specific details.
Withdrawal requests at bigtk are generally processed within 30 minutes to 3 hours. The process is faster for accounts that have completed KYC verification. Bank transfers may experience slight delays at night or on banking holidays.
The minimum withdrawal amount at bigtk is ৳1,000. Before submitting a withdrawal request, make sure your wallet has a sufficient balance and that any bonus wagering requirements have been met. Withdrawals may be held if the requirements are not fulfilled.
Contact us immediately via live chat or at [email protected] and provide a screenshot of the transaction along with the amount and time. The bigtk support team will quickly verify the matter and help resolve the issue. Keeping the correct reference number on hand will speed up the process.
Section 03
Games and Rules
At bigtk you can bet on BPL and cricket matches from around the world. Place bets on various markets before the match starts or while it is live — match winner, top run scorer, total runs, and more. Review the odds carefully before placing a bet and stay within your budget.
RTP (Return to Player) is the theoretical percentage of total wagers that a slot game returns to players over the long term. For example, an RTP of 96% means that on average ৳96 is returned for every ৳100 wagered. This is a mathematical average; results in each individual session may vary.
bigtk's live casino features a variety of popular table games including live roulette, live blackjack, live baccarat, live dragon tiger, and Andar Bahar. Games from several well-known providers including Evolution Gaming and Ezugi are available. Dealers are available at all times according to Bangladesh time.
Yes, bigtk is fully mobile-friendly. Simply open bigtk.cam in the browser on any Android or iOS smartphone, log in to your account, and you can access all games, betting markets, and payment features. No separate app download is required.
The game software used by bigtk comes from well-known providers including Pragmatic Play, JILI, PG Soft, and Spribe, all of which use Random Number Generator (RNG) technology. This technology makes every outcome completely random and not predetermined, which ensures fair play.
Section 04
Bonuses and Promotions
Open a new account and make your first deposit of at least ৳500, and bigtk will give you a 120% first deposit bonus of up to ৳20,000. That means if you deposit ৳10,000 you will receive an extra ৳12,000 in bonus funds, giving you a total balance of ৳22,000. The bonus is added to your account automatically.
The wagering requirement for the bigtk welcome bonus is 20x. This means you need to wager an amount equal to the bonus multiplied by 20 before you can withdraw. For example, a ৳5,000 bonus requires ৳100,000 in wagers. The contribution rate may differ by game — check the full terms and conditions for details.
bigtk has three VIP levels — Bronze, Silver, and Gold. You can advance to higher levels based on your regular play and deposits. Bronze offers up to 0.5% weekly cashback, Silver offers 1.0%, and Gold offers 1.5%.
Yes, taking a bonus at bigtk is entirely optional. If you choose not to take a bonus offer at the time of deposit, the funds will be added directly as real money and you can withdraw at any time. This is convenient for those who prefer flexibility without wagering requirements.
VIP cashback is calculated each week and is generally added to your account at the start of the following week. Cashback is usually withdrawable with low or no wagering requirements. Visit the VIP section or live chat support for specific terms.
