Before you install
Open the download guide if you have not downloaded the APK or have an unfinished download. Check the file source, Android compatibility and available storage before continuing. Android menu labels differ by manufacturer and system version.
Keep Play Protect enabled. An installation permission lets a selected app request an install; it does not certify that the package is safe.
Install a completed APK
- Open the completed file from your browser’s Downloads list or Android Files.
- If Android blocks installation from this source, read the prompt. Only for a source you have verified, open its Install unknown apps permission in Settings. On recent Android versions this permission is specific to the browser or file manager.
- Return to the installer and review the app name, permissions and any security messages.
- If the details match what you intended and no security issue is reported, choose Install. Wait until Android confirms completion.
- Open the app, then turn off the temporary Allow from this source permission when you no longer need it.
If Android or Play Protect flags a harmful app, stop and verify the source with the publisher. Do not disable scanning or install a modified package to get around the warning.
Match the error to the next check
| Message or symptom | Possible cause | What to do |
|---|---|---|
| App not installed | Insufficient storage, incompatible build or conflict with an existing installation | Check storage and device requirements. Record the full error; if updating, verify the source and app identity before uninstalling anything. |
| Problem parsing the package | Incomplete file or a package your Android version cannot read | Check the browser’s download status and the stated Android requirements. Obtain the file again from the verified route if incomplete. |
| Installation from this source is not allowed | The browser or file manager lacks installation permission | Review the source before granting temporary, app-specific permission. A managed device may require its administrator. |
| Blocked or harmful-app warning | Android security has raised a concern | Stop. Keep security scanning on and ask the publisher to clarify the warning. |
| App opens and closes | Compatibility, a faulty build, storage or a runtime problem | Restart the phone, check for a supported update and note the Android/app versions for platform support. |
| App opens but cannot load or sign in | Connection, account or service issue | Check your connection and the platform’s current service status. Use the login help checklist. |
These are diagnostic possibilities, not a way to identify a cause from the message alone. Change one thing at a time so you can tell what helped.
Update or reinstall?
An update replaces a compatible installed build and usually retains app data. Use the existing app’s update route or the same publisher’s download source. A rejected update can mean the package identity, signing certificate or version does not match.
A reinstall first removes the app and may erase local preferences and locally stored data. Before uninstalling, make sure you know your account login and can receive recovery messages. Do not assume local files are backed up, or that reinstalling will resolve an account restriction.
A failed update is a reason to check the package, not a reason to delete a working app immediately. For persistent errors, send the exact message, device model and software versions to the platform’s support channel. Do not share passwords or OTPs.

First Launch: Register, KYC, Bonus and Payouts
Once the app opens, the sensible order of operations is below. Doing these in sequence — rather than jumping straight to games — saves you delays later.
- Register with your mobile number. Use the number you'll keep long-term and that receives SMS reliably, because you'll use OTPs to log in from new devices. The download page notes one account is allowed per mobile number.
- Complete KYC early. Withdrawals need it, and doing it right after registration means it's never a surprise. Our KYC verification guide covers the documents and how to avoid the common rejections.
- Understand the welcome bonus before claiming it. The ₹10,000 welcome bonus is tied to your first deposit, and the wagering terms decide whether it's worth using. Read the welcome bonus breakdown first. The site also advertises cashback on deposits — see the cashback bonus guide for how that type of offer generally works.
- Make a first deposit you're comfortable losing. Set the amount before you open a game, not after. The bankroll management guide explains how to size deposits and sessions sensibly.
- Test a small withdrawal path. Once KYC is approved, know how payouts work — the UPI withdrawal guide walks through it, including the details that cause delays.
None of this is difficult, but it's much easier to do it calmly on day one than in a hurry when you've won and want to withdraw. Keep in mind too that gaming involves financial risk and there is no guarantee of winnings — the install is the easy part.
