Quick answer: To download the in999 app, open the download page in your Android browser, enable Install from Unknown Sources, download the APK (version 1.1.1.1), and install it. The whole process takes about 5 minutes. There is no Google Play version because real-money gaming apps are not permitted on the Play Store in India.

App overview

The in999 app is the Android client for the in999 platform. It provides access to all game categories — Wingo, Aviator, K3 Lottery, 5D Lottery, Slots, Cricket, Fishing, Poker, and the Original in-house titles including Mines, Dice, and Gold Wave.

The app is distributed as a direct APK download. It is not available on the Google Play Store. The current version is 1.1.1.1. The APK file size is approximately 15 to 20 MB, and the app runs on Android 6.0 (Marshmallow) and above.

Unlike some platforms that require a separate browser extension or a launcher, in999 works as a standard Android app. Once installed, it opens in full-screen mode and behaves like any other app on your phone — with push notifications, background updates, and offline access to cached data.

Why in999 is not on the Google Play Store

Google Play Store policy prohibits real-money gaming apps in India unless they fall under specific categories like fantasy sports or rummy (with state-specific rules). Colour prediction apps do not qualify. As a result, platforms like in999 distribute their APK directly from their official website.

This is why users see a warning about installing apps from "unknown sources" when they first install in999. The warning is a standard Android security measure, not an indication that the app itself is unsafe.

Security reminder: Only download the in999 APK from the official page. Third-party APK mirrors can bundle malware or modified code. Verify the version number shows 1.1.1.1 before installing.

How to download the APK

The download page shows a banner at the top that says Install the 1.1.1.1 app now to access in999, enjoy attractive rewards, and enhance your chances of success. Tapping the download icon in the top-right corner of the page starts the APK download.

Before downloading, check that your phone has at least 50 MB of free storage and a stable internet connection. The download usually completes in under a minute on 4G or Wi-Fi.

Step-by-step installation

Android blocks APK installation from unknown sources by default. You need to enable this setting once for your browser.

Open the download page

Open the in999 app download page in Chrome or any Android browser. A download prompt will appear at the top of the page.

Allow installation from unknown sources

Go to Settings → Security → Install Unknown Apps. Select your browser and enable Allow from this source. On newer Android versions, this prompt appears automatically when you first try to install the APK.

Download the APK file

Tap the download button on the page. The APK file (version 1.1.1.1) will download to your phone's Downloads folder. Wait for the download to complete before proceeding.

Install the APK

Open the downloaded APK from your notifications or from the file manager. Tap Install. Android will verify the package and install it in a few seconds.

Open the app and log in

Launch the in999 app from your home screen. Enter your registered mobile number with the +91 prefix or your email address, then tap Log in. New users can tap Register and use invite code 187587458275 to unlock the ₹500 gift bonus.

App features

  • Full game library. Wingo, Aviator, K3 Lottery, 5D Lottery, Slots, Cricket, Fishing, Poker, and Original games — all accessible from one app.
  • Faster load times. The native app loads game screens faster than the mobile browser, which matters during 60-second Wingo rounds.
  • Push notifications. The app notifies you about bonus drops, VIP level changes, and gift code redemptions.
  • Add to Desktop shortcut. A prompt inside the app creates a home-screen icon that opens the H5 version in full-screen mode.
  • All payment methods. UPI-QR, Paytm-QR, USDT, and ARPay — same as the web version.
  • VIP and bonus dashboard. Track VIP EXP progress, rebate earnings, attendance streaks, and first deposit bonus tiers from the Account tab.

App vs mobile browser

Both the Android app and the mobile browser give access to the same games and balance. The choice depends on how you use the platform.

InstallationRequired (APK)None — open and play
Load speedFasterDepends on browser and network
Push notificationsYesNo
Data usageLower per sessionSlightly higher
Works on iPhoneNoYes (Safari / Chrome)
Auto-updatesManual APK updateAutomatic
Recommendation: Use the app if you play daily. Use the browser if you play occasionally or use iPhone. Both give the same account and balance.

Add to Desktop shortcut

When you open the in999 web version on Android, a yellow banner appears at the bottom of the screen that says Add to Desktop. Tapping this banner creates a shortcut on your home screen. The shortcut opens the in999 H5 version in full-screen mode, without browser address bars.

This is different from the APK. The H5 shortcut does not need installation from unknown sources, and it updates automatically whenever the web version updates. For users who do not want to install the APK, Add to Desktop is a middle ground between the app and the browser.

iOS alternative

There is no separate iOS app for in999. iPhone users access the platform through Safari or Chrome. To add it to the home screen on iPhone:

  1. Open in999 in Safari on your iPhone. Log in or register with invite code 187587458275.
  2. Tap the Share icon at the bottom of the Safari toolbar.
  3. Scroll the share menu and tap Add to Home Screen.
  4. Name the shortcut "in999" and tap Add.
  5. The in999 icon appears on your home screen. Tapping it opens the platform in a Safari web app shell.
