IN999 App Download: Setup & Safety Guide
How to get the app installed on Android, what to check before you sideload, and when the browser is the better choice.
Download Options Overview
This is an independent explainer of the app-download process — not official installation documentation, and not a claim of affiliation with any operator. There are two realistic ways to play on a phone: install the Android app directly (commonly distributed as an APK rather than through the Play Store), or skip installation entirely and play through your mobile browser. Neither option is objectively "better" — it depends on how often you play and how much you care about home-screen convenience versus zero setup.
For a narrower, APK-file-specific walkthrough covering verification and update steps in more depth, see our dedicated APK download guide. This page instead covers the whole picture — app versus browser, setup, and safety.
Most players end up trying both at some point. It's common to start in the browser because it takes zero setup, and then move to the app later once you know you'll be playing regularly enough that a faster, dedicated shortcut is worth the few minutes it takes to install. Neither path locks you out of the other — your account and wallet follow your login, not the device or method you used to sign in last.
Faster Access
Skip the browser and open games directly from your home screen.
Lighter on Data
A native app typically loads game assets more efficiently than repeated page loads.
One-Tap Return
Stay signed in between sessions instead of navigating back to a URL each time.
Android Install: Step by Step
- Download the APK file from the download page or by scanning the QR code above.
- Once the download finishes, open your notification shade or Downloads folder and tap the file.
- If prompted, allow installs from this source (see the next section for exactly how).
- Tap Install and wait for the process to finish — this usually takes a few seconds.
- Open the app, then log in or register to reach your wallet and the games lobby.
Because the app isn't distributed through the Play Store, Android treats it as a sideloaded install and will show a security prompt the first time — that's expected behaviour for any APK from outside the store, not a sign that something is wrong.
Enabling Unknown Sources Safely
Modern Android versions ask you to approve installs on a per-app basis rather than with one global switch. The path is typically: open Settings → Apps → Special access (or Security on older versions) → Install unknown apps, then select the browser or file manager you used to download the APK and toggle Allow from this source.
The safer habit is to enable this only for the specific app you used to download the file, install what you need, and then turn the permission back off afterward. Leaving unknown-app installs permanently enabled for every app on your phone is unnecessary risk you don't need to carry.
Prefer the Browser Instead?
You don't have to install anything to play. Opening the site directly in your mobile browser gives you the same account, wallet and games lobby without a download, an install prompt, or any storage used on your device. It's the lower-friction choice for occasional players, or for anyone on a work or shared device where installing outside apps isn't practical.
The trade-off is convenience over time — a browser tab doesn't sit on your home screen, and you'll re-enter the address (and possibly your login) each session rather than tapping straight in. If you play often, most players eventually move to the app for that reason alone.
Storage & Compatibility Notes
The app is built to be lightweight, but plan for roughly 100 MB of free storage to cover the initial install plus room for cached game assets afterward. Most devices running Android 7.0 or newer are supported; very old devices or heavily customised Android builds occasionally run into compatibility quirks.
A stable internet connection matters more than raw phone specs — prediction rounds move quickly, so a shaky connection is more likely to cost you a missed bet window than a slower processor is.
If storage is tight, clearing the app's cache periodically (rather than uninstalling and reinstalling) usually frees up space without touching your login session. And if you ever switch phones, remember that the install itself carries no data with it — your balance, history and settings all live server-side, so signing in on the new device picks up exactly where you left off.
Safety Checklist Before You Install
Confirm the download link or QR code comes from a source you trust before tapping it.
Check the file size and version shown on the download page roughly match what you expect.
Re-enable install restrictions after you're done, instead of leaving unknown sources permanently on.
Keep your device's own security software up to date alongside any app you install.
Only enter your login details inside the installed app itself, never in a pop-up or link that arrived unprompted.

Frequently Asked Questions
Is the app available on the Play Store?
Typically not — that's why it's distributed as a direct APK download and requires enabling installs from outside the store.
Does the app work on iPhone?
The direct APK install path described here is Android-specific; iPhone users generally rely on the browser-based version instead of a native install.
Will installing the app cost me anything?
The download and install itself is free — any spending happens later, inside your wallet, once you choose to fund it.
Do I lose my account if I switch between app and browser?
No — your account and wallet are tied to your login credentials, not the device or method you use to access them, so you can move between app and browser freely.
