Your full lobby, pocket-sized

Once installed, the c5i app opens directly to your lobby — live Roulette and Dream Catcher tables stream without lag, slot rooms like Gates of Olympus and Mahjong Ways load in seconds, and the sportsbook betslip sits one tap away. Push notifications let you know when a table seat opens or a market goes live. Quick deposit via UPI, Paytm or PhonePe

clears right inside the app, and fingerprint login means you are at the tables in under ten seconds from your lock screen.

APP FEATURE SET

Six things that make mobile play faster

These are the features our app adds on top of a standard mobile browser session — each one built around how you actually use your phone during the day.

Fingerprint login Authenticate with your device fingerprint and land inside your account in under ten seconds. No password typing on a small keyboard, no session time-outs forcing re-entry mid-session.

Dark mode Switch to dark mode in Settings and the lobby shifts to a low-glare palette. Easier on the eyes during evening sessions and saves battery on AMOLED screens common in mid-range Indian handsets.

Push notifications Opt in to alerts for live table seat availability, upcoming sports kick-offs or new slot rooms added to the lobby. Tap the notification and the app opens directly to that room.

Offline lobby preview When your connection drops, the app shows the last cached lobby so you can browse game tiles, check odds and queue your next action. Live streams resume the moment connectivity returns.

Quick deposit chip A persistent chip row in the app header keeps UPI, Paytm and PhonePe one tap away. Initiate a deposit without navigating away from the table you are watching — the deposit screen overlays the lobby.

Betslip on the go Add selections from the sportsbook while you are in a live casino room. The betslip counter updates in the corner — switch to it, confirm your stake and return to the table without losing your seat.

Install in 3 steps on Android

Android installation uses our APK direct from this page — no third-party app store needed. The file is code-signed, so your device can verify its integrity before it runs. iOS installation follows the standard App Store flow. Entire process from download to your first lobby view takes under two minutes on most devices.

Download the APK — Tap the Download APK button on this page. The 30MB file transfers over your mobile data or Wi-Fi and lands in your Downloads folder.
Allow install from this source — Android will prompt you to allow installation from this source. Go to Settings, find the browser or file manager you used, and toggle Install unknown apps on. This is a one-time step.
Open the file and install — Tap the downloaded APK in your notification shade or Downloads folder. Android runs a package check, then installs. The c5i icon appears on your home screen when done.
Open and sign in — Launch the app, enter your c5i account credentials or create a new account, and set up fingerprint login when prompted. Your full lobby is ready immediately after sign-in.

APP SECURITY SIGNALS

Why the c5i app is safe to install

Every build we ship goes through code signing and integrity checks before it reaches you.

Code-signed APK

Every Android build carries a cryptographic signature tied to our developer certificate. Android verifies this before install — a tampered file will fail the check and not run on your device.

Direct distribution only

We do not list on unofficial APK mirror sites. The only source for our Android build is c5i.club. If you find it elsewhere, that copy has not been verified by us and we cannot vouch for it.

Encrypted account sessions

All communication between the app and our servers uses TLS encryption. Your account credentials, deposit requests and game data travel over an encrypted channel at all times.

Biometric authentication

Fingerprint login uses your device's secure enclave — your biometric data never leaves your phone. We only receive a pass or fail signal from the device operating system.

Account recovery path

Lose access to your device? Account recovery is handled via your registered email and a one-time verification step. Contact support and we walk you through it without resetting your balance or history.

Version integrity checks

The app checks its own version integrity each time it launches and prompts you to update if a newer signed build is available. Running an outdated version is flagged, not silently allowed.

App experience against mobile browser

If you have been using c5i through your phone's browser, here is what changes when you switch to the dedicated app — the differences are practical, not cosmetic.

Login speed	Browser sessions require you to type credentials every time cookies expire. The app keeps you authenticated with fingerprint login, cutting your entry time from thirty seconds to under ten.
Push notifications	Browser tabs cannot push alerts to your lock screen. The app delivers live table and sportsbook notifications the moment they trigger, even when the app is running in the background.
Offline lobby view	A browser tab goes blank when connectivity drops. The app caches the lobby so you can browse game tiles and check odds while your signal recovers — useful on Indian metro networks.
Deposit flow	Browser-based UPI deposits sometimes open a new tab and lose your place in the lobby. The app's overlay deposit screen keeps you on the same page and returns you to it after payment confirms.
Home screen access	Bookmarking a browser page is an extra step most skip. The app icon sits on your home screen — one tap, no address bar, no waiting for the page to resolve DNS.
Live stream quality	The app allocates video buffer differently from a browser and handles adaptive bitrate switching more smoothly on variable mobile connections common outside major Indian cities.

Common questions about the c5i app

Here are the questions we hear most from people downloading the app for the first time — covering installation, device support, payments and account access.

Download the APK directly from c5i.club. We do not distribute through third-party APK sites — the only verified source is our own domain. Tap the download button and the file lands in your Downloads folder.

Yes. The iOS build is available via the App Store where local law permits. Search for c5i or follow the link on this page. You need iOS 14.0 or newer on your iPhone or iPad.

Android restricts APK files not downloaded from the Play Store by default. Go to Settings, find the browser or file manager you used, and enable Install unknown apps. It is a one-time permission for our APK only.

Yes. UPI, Paytm and PhonePe are all available inside the app through the deposit overlay. Initiate from the chip row at the top of the lobby without navigating away from whatever room you are in.

After your first manual login, the app prompts you to enable biometric login. Your fingerprint data stays in your phone's secure enclave — we only receive a pass or fail signal. No biometric data is stored on our servers.

Force-close the app, clear its cache in your phone's App Settings, then reopen. If the problem persists, uninstall and re-download the APK from c5i.club to ensure you have the latest signed build.

The app is built to run on devices with a minimum of 2GB RAM running Android 8.0 or newer. Live video streams may buffer on very congested connections — switching to a Wi-Fi or 4G network usually resolves this.
