Many sites flash big numbers but bury the real terms in fine print. OKBK promotions are designed differently — the conditions are straightforward, clearly stated, and genuinely usable. Whether you're playing from Mymensingh or Barisal, every OKBK offer applies equally to you.
Every offer clearly displays its expiry date, minimum deposit, and wagering requirements right alongside it. No hidden terms — what you see is what you get. New members get a bonus on their first deposit; existing members enjoy regular cashback and seasonal offers.
Eid ul-Fitr, Eid ul-Adha, Pohela Boishakh, BPL season — OKBK runs special promotions for every major Bangladeshi occasion. Bookmark this page so you're always the first to know when a new offer goes live.

Claiming a bonus at OKBK isn't complicated. Most bonuses are added automatically. Some require a promo code — the step-by-step process is laid out below.
New here? Register now. Already a member? Log in directly and head to the promotions page.
Enter the code in the promo code box on the deposit page. No code is needed for automatic bonuses.
Make a minimum deposit. It takes just 3 minutes via bKash or Nagad.
Your bonus will appear in your balance as soon as the deposit is confirmed. Start playing now.
Once the required wagering is complete, winnings from the bonus can be withdrawn.
Wagering requirements confuse a lot of people, but they're actually quite simple.
If you receive a ৳1,000 bonus with a 10x wagering requirement, you'll need to place a total of ৳10,000 in bets. That's the same as placing a ৳100 bet 100 times. You don't have to do it all at once — take your time and complete it gradually.
Slots: 100%, Sports Betting: 100%, Live Casino: 100%. (Contribution may vary for certain games.)
If the wagering requirement isn't met within the set timeframe, the bonus will be cancelled. Your original deposit remains unaffected.
OKBK has dedicated promotions for Sports Betting fans. Boosted odds before big matches, free bets on select games, and bonuses for winning streaks — together, these make betting on sports even more rewarding.

All promotions are exclusively for verified OKBK account holders. Each bonus can only be claimed once per person. Claiming bonuses across multiple accounts from the same device or IP address is strictly prohibited.
Bonus funds are held in a separate bonus wallet. Winnings from gameplay are credited to your main balance. The bonus balance cannot be withdrawn directly until the wagering conditions are met.
You cannot claim a new bonus until the wagering on your current one is complete. The exception is cashback bonuses — those are available to you at any time.
All bonuses apply in BDT. Simply deposit via bKash, Nagad, Rocket, or crypto and your bonus activates automatically.
If the wagering requirement isn't met within the specified timeframe, the bonus is automatically cancelled. You can request an extension through support, but approval is not guaranteed.
If any suspicious activity is detected, OKBK reserves the right to cancel bonuses and investigate the account. Fair play is our policy.
