Download the okzz app and take your favourite casino games wherever you go. Dragon Tiger, Bird Catcher, Win Drop, and more — all running smoothly on your Android or iOS device. Built for Bangladesh players, optimised for mobile networks.
Everything you get on the website, packed into a fast and lightweight mobile app.
The okzz app is built lean. It loads in under two seconds even on a 3G connection, so you are never waiting around when you want to place a bet or spin a game. No lag, no freezing — just smooth gameplay from the moment you open the app.
Your okzz account and payment details are protected by 256-bit SSL encryption inside the app. Biometric login — fingerprint or face ID — means only you can access your account, even if your phone is lost or stolen.
Top up your okzz balance directly from the app using bKash, Nagad, or Rocket. Withdrawals are processed just as fast. No need to open a browser — everything happens inside the app in a few taps.
Never miss a promotion again. The okzz app sends you push notifications when new bonuses drop, when your cashback is ready to claim, or when a limited-time offer is live. Stay ahead of other players with real-time alerts.
Every game available on the okzz website is also available in the app. Dragon Tiger, Bird Catcher, Win Drop, Ultra Treasure, Captain Fisher, Multi Bet — the full catalogue is right there in your pocket, ready to play any time.
The okzz app updates itself silently in the background so you always have the latest version without doing anything. Certain features also work in low-connectivity mode, so a weak signal does not ruin your session.
Getting the okzz app on your phone takes less than two minutes. Follow these steps.
Open your mobile browser and go to okzz.casino/app. You will see the download buttons for both Android and iOS. Make sure you are on the official okzz website before downloading anything.
For Android users, go to Settings > Security and enable "Install from Unknown Sources" or "Allow this source" when prompted. This is required because the okzz APK is distributed directly, not through the Play Store.
Tap the Android APK or iOS button and wait for the file to download. On Android, open the APK file and tap Install. On iOS, follow the on-screen prompts to add the app to your home screen.
Open the okzz app, then either log in with your existing account or tap Register to create a new one. New players get a 100% welcome bonus on their first deposit, applied automatically.
Add funds via bKash, Nagad, or Rocket directly inside the app. Your balance updates instantly and you can jump straight into any game in the okzz library.
Tip for Android users: After installing the okzz app, you can turn "Unknown Sources" back off in your settings. The app is already installed and this setting only applies during installation.

Most international casino apps are built for high-speed broadband connections and flagship smartphones. That does not work for most players in Bangladesh, where mobile data speeds vary and older Android phones are still very common. The okzz app was designed with this reality in mind from day one.
The app file size is kept deliberately small — under 50 MB — so it downloads quickly even on a slow connection. Once installed, it uses compressed assets and smart caching to make sure game graphics load fast without eating through your mobile data. If you are on Grameenphone, Robi, Banglalink, or Teletalk, the okzz app is built to work well on your network.
Payment integration is another area where the okzz app stands out. bKash, Nagad, and Rocket are all natively supported inside the app. You do not need to copy account numbers or switch between apps — the okzz app handles the payment flow directly, so deposits and withdrawals are done in a few taps. Most deposits reflect in your okzz balance within 30 seconds.
The okzz app also remembers your preferences. Your favourite games are pinned at the top of the lobby. Your last played game is one tap away. Notification settings let you choose exactly which alerts you want — bonus drops, withdrawal confirmations, or new game launches — so you only hear about the things that matter to you.
Security inside the okzz app is taken seriously. Every session is encrypted end-to-end. If you enable biometric login, your credentials are stored in your phone's secure enclave — not on okzz servers — which means even a data breach cannot expose your login details. Two-factor authentication adds another layer on top of that.
For players who travel or move between locations, the okzz app handles network switching gracefully. If you drop from 4G to 3G mid-game, the app reconnects automatically without losing your session or your bet. That kind of reliability is something a browser tab simply cannot match.
Responsible Gaming: The okzz app includes built-in tools to help you stay in control. Set daily deposit limits, session time reminders, or self-exclude directly from the app settings. Visit Responsible Gaming for more details.
