Below are 3999but's most popular and currently active voucher codes. Copy any code and redeem it directly in your account.
On most online gaming platforms, a "voucher" or "promo code" is either a marketing gimmick or comes buried under so many conditions that the actual benefit is hard to reach. 3999but's voucher system is built differently. Every voucher code comes with clear, upfront terms — the bonus amount, wagering requirements, and expiry date are all stated in plain sight. No hidden traps.
For Bangladeshi players, 3999but specially designs vouchers around local festivals and seasons. Dedicated codes for Eid, special offers for Pohela Boishakh, sports vouchers during the World Cup — everything reflects the tastes and culture of Bangladesh. This isn't just a platform; it's Bangladesh's own online gaming experience.
Redeeming a voucher code is straightforward. Log in to your account, go to the "Voucher" or "Promo Code" section, enter the code, and click "Apply". The bonus will be credited to your account instantly. Most vouchers activate as soon as you make a deposit via Mobile Pay, Nagad, or bank transfer.
3999but offers five types of vouchers in total. First, the Welcome Voucher — available to new members on their first deposit. It provides the largest bonus, making it the most important code for newcomers. Second, the Reload Voucher — usable every time you make a deposit, with bonuses ranging from 25% up to 200%.
Third, free spin vouchers — great for slots fans. Use these codes to spin on selected games at no cost, with any winnings added straight to your real balance. Fourth, cashback vouchers — if you end a session at a loss, you get a set percentage back. Fifth, Sports Betting vouchers — designed specifically for cricket and football betting, offering bet bonuses or boosted odds.
Keep notifications turned on in your 3999but account and you'll be alerted by SMS and email the moment a new voucher code drops.

Many players receive voucher codes but miss out simply by not using them correctly. Follow these simple tips to get the most out of 3999but. First, always check the expiry date — even a great code is worthless once it's expired. Make it a habit to check 3999but's voucher page once a day so you never miss an offer.
Second, it's important to understand wagering requirements. A large bonus with high wagering may actually be less valuable than a smaller bonus with lower wagering. Choose a voucher that fits your playing style and budget. Third, keep your cashback voucher active at all times — it works without any deposit and acts as insurance against losses.
Fourth, subscribe to 3999but's newsletter and keep app notifications turned on. Exclusive vouchers are often sent only via email or SMS — and never shown on public pages. VIP members tend to receive more of these private codes. So if you play regularly and accumulate loyalty points, reaching a higher VIP tier can unlock even more vouchers.
3999but fully supports Mobile Pay, Nagad, and Rocket — Bangladesh's three most popular online payment methods. After redeeming a voucher, your bonus balance is credited instantly, and once wagering requirements are met, withdrawals via Mobile Pay or Nagad are completed within minutes.
3999but occasionally offers extra cashback vouchers specifically for Mobile Pay users — for example, an additional 5% bonus when you deposit via Mobile Pay. These payment-specific offers are listed in a dedicated section on 3999but's voucher page. Special codes are available for bank transfer users as well, though processing times may be slightly longer.
For security, every voucher code on 3999but is tied to a specific account. If someone tries to use the same code on multiple accounts, the system will automatically reject it. This effectively prevents abuse and protects fair players. Never trust codes shared by others — always get your codes directly from 3999but's official page.
