Enjoy all of OKBJ's games and betting features anytime, anywhere. Installation takes just a few seconds — no hassle at all.
The OKBJ app is completely free on both Android and iOS.
The OKBJ Android app is available as a direct APK download. Once installed, games load in just 2–3 seconds — and it runs smoothly even on a weak network connection.
The OKBJ app runs great on both iPhone and iPad. Game graphics look even more vibrant on a Retina display. You can also play via Safari.
Install in just 5 easy steps — takes less than 5 minutes.
Go to Settings → Security → Unknown Sources and toggle it on. This only needs to be done once, and you can turn it off again afterwards.
Tap the "Download Android APK" button above. The file will be saved to your phone's Downloads folder.
Open your Files or File Manager app, navigate to the Downloads folder, find the OKBJ APK file, and tap on it.
When prompted for permission, tap "Install". The installation will be complete within 15–30 seconds.
Open the app, log in if you already have an account, or create a new one in just 1 minute.
On iOS, simply add it directly as a web app using the Safari browser.
Open Safari on your iPhone and go to okbj.bet. You must use Safari — not Chrome or Firefox.
Tap the Share icon (box with an arrow pointing up) on the bottom toolbar. A menu will slide up.
Find the "Add to Home Screen" option in the menu and tap it. You'll see the OKBJ icon appear on your screen.
Tap the "Add" button at the top right. The OKBJ icon will be added to your home screen.
Now tap the OKBJ icon on your home screen and it opens in full-screen, just like a native app.
Playing on the app is easier, faster, and more enjoyable than playing in a browser.
Mobile internet usage in Bangladesh is growing every day, and so is the appetite for online gaming and betting. OKBJ recognizes this demand and has built an app that fits seamlessly into the daily lives of Bangladeshi users.
Riding a rickshaw through Dhaka's busy streets, taking a break at Chittagong port, or sitting by a tea garden in Sylhet — the OKBJ app works wherever you are. Games run smoothly even on a 3G connection, which is why the user base keeps growing every month.
Download the OKBJ app and get every feature the website offers — packed into one compact app. Play 500+ games including Aviator, Crazy Time, and Sweet Bonanza, all directly from the app. Place live bets on cricket, football, and more while watching real-time odds.
OKBJ's Live Casino experience is in a league of its own. Playing Baccarat, Teen Patti, or Roulette with a live dealer on the app, you'd never guess you're on a small phone screen — the graphics and streaming quality are that good.
The OKBJ app supports Bangladesh's most popular deposit and withdrawal methods. bKash, Nagad, and Rocket can all be used directly from the app. Bank transfers and USDT are also accepted. Deposits typically reflect in your account within 2–5 minutes.
Withdrawals are just as quick with OKBJ. In most cases, funds are sent within 24 hours — often even sooner. This speed is one of the main reasons users prefer OKBJ.
Many users wonder whether they can just play in a browser without downloading the app. The short answer: yes, the browser works fine. But the app offers a few extras you won't get in a browser — like push notifications, fingerprint login, and access to certain features in offline mode.
OKBJ uses industry-leading technology to keep your data secure. With 256-bit SSL encryption, your login credentials, personal information, and transaction details are fully protected. Your data is never shared with any third party.
The app is updated regularly to include new security patches. You don't need to update it manually — the app updates itself in the background.
Many users run into small issues when downloading the OKBJ APK for the first time. The most common one is forgetting to enable "Unknown Sources" — an Android security feature that blocks app installations from outside the Play Store. Just go to Settings and turn on that option, and the installation will go through without a hitch.
Another common issue is insufficient storage. The OKBJ app itself is only 28 MB, but after installation it takes up around 50–60 MB including cache. Keeping at least 100 MB of free space on your phone should prevent any problems.
OKBJ customer support is available 24 hours a day. If you run into any issues downloading or installing the app, contact support directly and get help in Bangla.
OKBJ works on both, but the app comes with a few extra benefits.
