Get started on iOSInstalling the bi999 app on your phone takes just a few simple steps. No technical knowledge needed — the process is straightforward.
Open bi999.win in your mobile browser. Go to the "App" section from the top menu, or navigate directly to the app download page.
Choose the right version for your device — Android or iOS. On Android, tap the APK button; on iPhone, follow the App Store link.
Go to Settings → Security and enable Unknown Sources or "Install unknown apps". This only needs to be done once for APK installation. The bi999 APK is completely safe and virus-free.
Tap the downloaded file and hit the "Install" button. Installation completes in under 30 seconds.
Open the bi999 app. Log in if you already have an account, or sign up for a new one. Make a deposit and jump straight into your game of choice.
The app offers a few extra features not available on the browser version
Once installed, games load up to 40% faster than in a browser. Gameplay stays smooth even on a weak network connection.
New bonuses, deposit confirmations, withdrawal updates — all notifications arrive directly on your phone. Never miss an offer.
Log in with your fingerprint or face in under a second. No more typing passwords.
Save your bKash or Nagad number and your next deposit is just one tap away. Payment confirmations are shown directly in the app.
Use Dark Mode for late-night sessions to reduce eye strain. The bi999 app automatically follows your phone's system theme.
The app stays stable even when your connection drops. It reconnects automatically once the network is restored, and you can still view your game history offline.
Mobile gaming is growing fast in Bangladesh. Most people now play on their phones rather than desktops or laptops — and bi999 built its app with exactly that in mind.
The bi999 app is just 5 MB. It stays lightweight because game data loads from cloud servers, so it doesn't take up much storage on your phone — without any compromise on game quality.
Many gaming apps lack local language support or require a foreign card to make payments. bi999 has a fully localized interface and supports direct deposits and withdrawals via bKash, Nagad, and Rocket. No extra hassle.
Bi999 app users get a little extra — weekly app-exclusive bonus offers that browser users don't have access to. A nice perk for regular players.
The bi999 app uses industry-leading security standards. Every session is encrypted, login is protected with two-factor verification, and you get instant alerts for any suspicious activity. Your account and funds are always safe.
