Click the wallet icon to go to the deposit page. Choose your payment method — Mobile Pay, Nagad, or Rocket.

Once your deposit is confirmed, the bonus will be credited to your bonus wallet. You can then use your bonus balance to bet on your favourite games or matches.
Vouchers and promo codes on online betting platforms can often be confusing. Some sites advertise huge bonuses, but the fine print makes them nearly impossible to claim. 3ok breaks away from that old pattern.
Every voucher code on this page has its terms listed right alongside it. No hidden conditions, no fine-print traps. What you see is what you get.
Whether you're in Chittagong, Dhaka, or anywhere else in the country — 3ok voucher codes work the same everywhere. Deposit via Mobile Pay, enter your code, and claim your bonus in seconds.
The welcome voucher is a one-time offer, so make the most of your first deposit. Put in ৳5,000 and a 100% bonus adds another ৳5,000 — giving you ৳10,000 to start with.

As online betting sites multiply in Bangladesh, so do fake vouchers and misleading offers. Ads promising "100% bonus" often come buried in so many conditions that most players never actually qualify.
3ok takes this seriously. Every voucher offer on our platform is written in plain language — conditions are clear and the bonus process is straightforward. We believe honest business is the best long-term strategy.
From the tea gardens of Sylhet to Bagerhat near the Sundarbans — millions of 3ok members across Bangladesh know that a voucher here means a real bonus. Visit our review page to read experiences from actual players.
New seasonal vouchers are added every month. Subscribe to the 3ok newsletter or enable push notifications on the app to receive special voucher codes during Eid, Puja, or the World Cup season.
What You Should Know Before Claiming a Bonus
Only use codes obtained from this page. Codes from third-party sites may not work.
Each voucher has a set expiry date. Once it expires, the code will no longer work and the bonus will be forfeited.
The welcome voucher can only be used once per account. Creating multiple accounts is strictly prohibited.
You need to wager a set amount before withdrawing bonus funds. For example, 5x means you must bet ৳5,000 on a ৳1,000 bonus.
