The ok zzz app is available on both Android and iOS. Download the version for your device below.
Install the ok zzz app in just a few simple steps — the process is straightforward for both Android and iOS.
On your phone, go to Settings → Security → Unknown Sources and enable it. This is required to install APK files. On Samsung phones, you'll find this under Settings → Biometrics & Security.
Tap the "Download Android APK" button above. The file will be saved to your phone's Downloads folder. Wait for the download to complete.
Go to your Downloads folder and tap the okzzz.apk file. When the installation window appears, tap "Install".
Once installation is complete, tap the "Open" button. Log in to your ok zzz account or create a new one.
Open okzzz.im in Safari on your iPhone or iPad. Chrome and Firefox work too, but Safari gives you the best experience.
Tap "Get iOS Version". The download will begin and an installation prompt will appear on your device.
Go to Settings → General → VPN & Device Management and tap Trust on the ok zzz Developer profile. You only need to do this once.
You'll see the ok zzz icon on your Home Screen. Tap it to open the app, then log in or register.
Note: Only download the ok zzz APK file from the official website at okzzz.im. Files downloaded from third-party sites are not safe and could harm your device. ok zzz never shares APK files via WhatsApp or Telegram.
Using the app instead of a browser gives you far more — from faster performance to exclusive offers
The ok zzz app loads up to 3x faster than a mobile browser and runs without a hitch even on Bangladesh's 3G networks.
Get instant notifications for lottery draws, betting results, and prize wins — never miss an important moment.
Log in to the ok zzz app for the first time and get a ৳200 bonus. Plus, there are app-only promo offers every month.
Log in to your account in just one second using your fingerprint or Face ID — no more remembering passwords.
Some app features work offline. Once your internet connection is restored, everything syncs back up automatically.
The ok zzz app is designed with a dark theme. It's easier on the eyes during late-night sessions and helps conserve battery life.
Smartphones are now central to everyday life in Bangladesh — from sending money via bKash to shopping online, everything happens on mobile. ok zzz keeps pace with that reality, offering a full-featured mobile gaming app built with Bangladesh's network conditions in mind.
Many people ask: why bother with a separate app when the browser works fine? The answer is simple. The ok zzz app gives you a completely different feel — a smoother interface, near-zero loading time when placing bets, and truly uninterrupted real-time updates for live events.
Another great advantage of the ok zzz app is its data-saving mode. Whether you're in a rural area or roaming, the app runs smoothly even on a limited connection. At just 48 MB, it works without a hitch on older phones too.
Deposits and withdrawals via bKash and Nagad can now be done directly within the app — no need to open a browser or visit the website separately. Once you save your bKash number in the ok zzz app, every future transaction takes just one tap.
The ok zzz mobile app includes a full lottery section — from Instant Win games to mega jackpots. You also get live betting on cricket, football, tennis, and other popular sports. The casino section features Roulette, Baccarat, Teen Patti, and much more.
The ok zzz app features a dedicated Rewards Hub. Open the app daily to claim your daily check-in bonus. Log in 7 days in a row and you'll unlock a special weekly reward. Rewards can be sent directly to bKash or used in-game.
Customer support is built right into the app. You can live chat from within the app whenever you need help. The ok zzz support team assists in Bangla, so there's no language barrier.
Installing an APK on Android requires enabling "Unknown Sources" — this is completely normal and safe. The ok zzz APK has been tested against Google Play Protect and contains no malware. After downloading, you can scan it with Avast or Kaspersky for peace of mind — it will pass clean.
IOS users need to complete the Developer Trust setting once. It may seem a bit technical at first, but ok zzz provides a detailed step-by-step guide with screenshots on its website. If you run into any trouble, contact live support — issues are typically resolved within minutes.
Please note: the ok zzz app is strictly for users aged 18 and above. Play responsibly and know your limits. You can set daily limits anytime in the ok zzz Responsible Gaming section.
