The ao999 app brings your entire gaming account to your pocket. Install it on Android or iOS and get instant access to all games, your wallet, live bonuses, and 24/7 support — no browser needed.
One lightweight app. Every feature you need to play, deposit, withdraw, and win on ao999.
The ao999 app is optimised for low-bandwidth connections common across Bangladesh. Games load faster than the browser version, even on 3G networks, so you spend less time waiting and more time playing.
Never miss a bonus again. The ao999 app sends you real-time push notifications for new promotions, deposit confirmations, withdrawal approvals, and game results — all delivered straight to your lock screen.
Log in to ao999 with your fingerprint or face ID on supported Android and iOS devices. No need to type your password every time — just tap and you are in within one second.
The ao999 app integrates directly with bKash and Nagad. Deposit or withdraw funds with a single tap from your wallet screen. Most withdrawals are processed within minutes, not hours.
Every ao999 game is available inside the app — Crazy 777, Color Prediction, Bird Catcher, Captain's Bounty, Triple, Slide, and more. Switch between games instantly without reloading or re-logging in.
The ao999 app uses the same Shadow Green Silver theme as the website — dark background, bright green accents, and soft gold highlights. It is easy on the eyes during late-night sessions and saves battery on AMOLED screens.
Installing the ao999 app on Android is straightforward and takes less than two minutes. Because the ao999 app is distributed as a direct APK file rather than through the Google Play Store, you need to allow installation from unknown sources before you begin. This is a standard step for any APK install and does not affect your device security when the source is trusted.
Go to Settings → Security (or Privacy on some Android versions) and enable "Install from Unknown Sources" or "Allow this source" for your browser. This setting allows your phone to install APK files downloaded from the ao999 website.
Tap the Android download button on this page. Your browser will download the ao999 APK file directly to your phone's Downloads folder. The file is approximately 18MB so it downloads quickly even on a mobile data connection.
Once the download is complete, tap the notification or open your Downloads folder and tap the ao999 APK file. Your phone will show an installation prompt. Tap "Install" to proceed.
After installation, tap "Open" or find the ao999 icon on your home screen. Log in with your existing ao999 credentials or register a new account directly inside the app. That is it — you are ready to play.
The ao999 APK is scanned for malware before every release. Always download the APK from ao999.io only — never from third-party sites or links shared in messaging apps.
iPhone and iPad users can access the ao999 app through a progressive web app (PWA) installation or via the direct iOS link on this page. The ao999 iOS experience is fully optimised for Safari on iPhone and gives you the same fast, smooth gameplay as the Android app.
On your iPhone or iPad, open Safari and navigate to ao999.io. Safari is required for the PWA install option — Chrome on iOS does not support home screen installation in the same way.
At the bottom of the Safari browser, tap the Share icon (the square with an arrow pointing upward). A menu will appear with various sharing and saving options.
Scroll down in the share menu and tap "Add to Home Screen". Give it the name "ao999" and tap "Add". The ao999 icon will appear on your iPhone home screen just like a native app.
From now on, tap the ao999 icon on your home screen to open the app in full-screen mode without any browser bars. Log in with your ao999 account and start playing immediately.
The ao999 PWA on iOS runs in full-screen mode, supports biometric login via Face ID, and loads your last session automatically. It behaves exactly like a native app without taking up storage space.
Both the ao999 app and the ao999 website give you access to the same games and account features. But the app has several advantages that make it the better choice for regular players in Bangladesh.

The ao999 app was built specifically for players in Bangladesh who want a faster, more convenient way to enjoy online gaming on their mobile phones. Most ao999 players access the platform through their smartphones, and the app is designed around that reality — lightweight, fast, and easy to use even on older Android devices with limited RAM.
When you use the ao999 app, you get the same account, the same balance, and the same bonuses as the website. There is no separate registration required. If you already have an ao999 account, just download the app, log in, and everything is exactly where you left it. Your game history, your wallet balance, your active bonuses — all synced in real time.
The ao999 app supports all the payment methods available on the website, including bKash and Nagad. Deposits reflect in your ao999 wallet within seconds, and withdrawal requests are processed through the same fast pipeline as the desktop version. There is no penalty or delay for using the app instead of the browser.
Security on the ao999 app is identical to the website. All data is transmitted over 256-bit SSL encryption. Your login credentials are never stored in plain text on your device. If you enable biometric login, your fingerprint or face data stays on your device and is never sent to ao999 servers — it is handled entirely by your phone's secure enclave.
ao999 occasionally runs app-exclusive promotions for players who log in through the mobile app. Make sure push notifications are enabled so you never miss an app-only bonus offer.
The ao999 app is updated regularly to add new games, improve performance, and fix any issues reported by players. Updates are delivered automatically if you have auto-update enabled, or you can manually download the latest APK from this page whenever a new version is released. The app version number is always visible in the Settings section inside the app.
For players who are new to ao999, the app is actually the easiest way to get started. The registration flow inside the ao999 app is streamlined for mobile — fewer steps, larger input fields, and a cleaner layout than a desktop browser. You can complete registration, make your first deposit via bKash, and start playing your first game in under five minutes.
The ao999 app is designed to run on a wide range of devices. Here are the minimum requirements:
If your Android device runs version 5.x or lower, use the ao999 mobile website in your browser instead. The website is fully responsive and works well on older phones.
