Deposits and Withdrawals
Answers to questions about depositing and withdrawing money via bKash, Nagad, and Rocket, including methods, timing, and fees.
bk664 currently supports deposits through three payment methods: bKash, Nagad, and Rocket. All three mobile banking services are widely used and trusted in Bangladesh. When making a deposit, use the correct account number and transaction ID so the process completes quickly.
The minimum deposit amount for each payment method at bk664 is ৳100. Whether you use bKash, Nagad, or Rocket, a minimum of ৳100 must be deposited. This amount is convenient for players of any budget.
Deposits via bKash are usually credited to your bk664 account within a few minutes. Providing the transaction ID correctly makes the process even faster. If the deposit does not appear for any reason, contact our support team via live chat with your transaction ID.
The minimum withdrawal amount from bk664 is ৳1,000. Withdrawal requests generally take 10 to 45 minutes to process. Providing the correct payment account number can reduce this time further. Nagad and bKash are popular choices for the fastest withdrawals.
bk664 does not charge any additional fees for deposits or withdrawals. However, your mobile banking provider (bKash, Nagad, Rocket) may apply their own service charges — these are determined by the terms of the respective service and are not within bk664's control.
Log in to bk664 and select the "Deposit" option. Choose Nagad and send the payment to the indicated number. After sending the payment, enter the transaction ID in the bk664 deposit form. Once approved, the balance will be added to your account. If you have any trouble, let us know immediately via live chat.

Games and Rules
Answers to questions about cricket betting, slot games, live casino, and fair play.
Go to the cricket section of bk664 and choose any match from the BPL season. You can bet on various markets before or during the match, such as match winner, run line, number of wickets, and more. Play within your budget and research the team's form and pitch conditions before placing bets.
In the bk664 Slots section, you will find a large collection from top game developers including PG Soft, Pragmatic Play, and JILI. In addition to popular games like Fortune Tiger, Gates of Olympus, Fortune Gems, and Sweet Bonanza, there are also fishing games, bingo, and many other categories. New games are added regularly.
RTP, or "Return to Player", is a game's long-term average payout rate. For example, a 96% RTP means that on average, ৳96 is returned for every ৳100 wagered over a long period. However, this does not guarantee winnings in any single session — short-term results are completely random (RNG-based). All games at bk664 are run on a fair play basis.
In bk664's live casino, you will find live table games from top providers like Evolution Gaming and Ezugi — Baccarat, Roulette, Blackjack, Teen Patti, and much more. Experience the feel of playing with a real dealer from the comfort of your home. You can join at any time as it runs 24 hours a day.
Yes, all games at bk664 are powered by Certified RNG (Random Number Generator) technology, which ensures every result is completely unbiased and unpredictable. We work with world-class game developers who are themselves subject to regular audits. Fair play is a core principle of our platform.
Section 04
Bonuses and Promotions
Learn about the welcome bonus, wagering requirements, VIP program, and cashback.
When you open an account at bk664 for the first time, you will receive a 100% bonus on your first deposit of up to ৳5,000. For example, depositing ৳5,000 will earn you an additional ৳5,000 as a bonus. A 15x wagering requirement must be met to use this bonus.
A wagering requirement is the number of times the bonus amount must be bet before it can be withdrawn. For the bk664 welcome bonus, the requirement is 15x. This means if you receive a ৳1,000 bonus, you must place a total of ৳15,000 in bets before withdrawing. This can be met through regular play over time.
bk664 has three VIP levels: Bronze, Silver, and Gold. By playing regularly, you can automatically move up to a higher level. Bronze members receive up to 0.3% cashback weekly, Silver members up to 0.7%, and Gold members up to 1.0% cashback.
Each week, a fixed portion of your net losses is returned as cashback based on your VIP tier. This cashback is credited directly to your bk664 account and can be used in your next game. It is a great benefit for regular players and helpful over the long term.
Yes, bk664 regularly brings promotional offers for special occasions — such as special betting bonuses during the BPL season, cashback offers during Eid ul-Fitr and Eid ul-Adha, and much more. Log in to your account to see active promotions and do not miss out.
