Follow these 5 simple steps to download and install ef99 App on your Android phone. The process takes less than 3 minutes.

  1. Enable Unknown Sources

    Go to Settings → Apps & notifications → Advanced → Special app access → Install unknown apps. Find your browser (Chrome, Firefox, etc.) and toggle on "Allow installation of apps from this source". This permission is required because ef99 App is distributed directly, not through Google Play Store.

    Click the Download APK Now button above or in the download section below. Your phone will save the file ef99.apk (36 MB) to your Downloads folder. Wait for the download to complete before proceeding to the next step.

  3. Open File Manager & Locate APK

    Open your File Manager or Files app. Navigate to Downloads folder and find the ef99.apk file. Tap on it to open the installation dialog. Your phone may ask for confirmation again.

  4. Tap Install & Accept Permissions

    Review the permissions list (camera, storage, location for sports betting features). Tap Install and wait 20–30 seconds. You'll see a progress bar. Once complete, the button changes to Open.

  5. Launch App & Log In

    Tap Open to launch ef99 App immediately, or find the ef99 icon on your home screen anytime. Log in with your ef99 account (or create a new one). You're ready to play slots, live casino, sports, and more.

iPhone & iPad Users: ef99 offers a mobile web app. Visit https://ef99.ws in Safari, tap Share → Add to Home Screen, and create a shortcut. You'll get app-like access without downloading from App Store. No additional permissions needed.

Security & Permissions Explained

ef99 App is scanned for malware and verified safe. Here's what permissions it uses and why.

  • SSL Encryption

    All data between your phone and ef99 servers uses 256-bit SSL encryption. Your account, balance, and payment details are protected from hackers. We never sell or share your data.

  • Camera Permission

    Used only for KYC verification (first withdrawal) and live camera chat with support. You control when it's accessed. Optional—skip if you use other ID documents (NID, passport, driving license).

  • Location & GPS

    Detects if you're in Bangladesh to comply with local regulations. Disabled automatically if you travel. Does not track you elsewhere. Optional permission—you can deny it.

  • Storage Access

    Saves game graphics and app cache (36 MB) on your phone to speed up loading. You can clear this anytime in Settings. Does not access private files.

What ef99 Does NOT Do: We never use your data for ads, never track background activity, never access your contacts or messages, never ask for permission we don't need. Permissions you deny don't break the app—features simply won't work.

Frequently Asked Questions About ef99 App

Is the ef99 App APK safe to download? Will it install malware?
ef99 App is 100% safe. We use SSL encryption, pass malware scans from Google Play Protect, and store the APK on trusted CDN servers. We never inject ads, spyware, or tracking software. Always download from this official page (https://ef99.ws/ef99-app/) and verify the file size is exactly 36 MB before installing. If you see a different size, stop and contact support immediately.
Can I play the same games on the App and web browser? Do bonuses stack?
Yes, you can play all 4500+ games on both the App and web version using the same account. Your balance syncs instantly between both. Bonuses and cashback do not stack—they apply once per promotion or day. For example, if you claim a ৳250 deposit bonus on the web, you cannot claim it again on the App using the same deposit. Browse all games available in both versions.
How often does ef99 App get updated? Will my login change?
We release updates every 2–4 weeks to add new games, fix bugs, and improve performance. Current version is 3.0.9 (released November 3, 2026). Your login ID and password never change—just use the same credentials. When a new version is available, a notification appears in the app. Download and install the latest version from this page to unlock new features and security patches. Old versions continue working but may be slower.
Does ef99 App work on slow internet or 3G? What about offline play?
ef99 App works best on 4G LTE or WiFi (minimum 2 Mbps). Some slot and Crash games can load on 3G but may freeze. We recommend upgrading to 4G for smooth play. No games run offline—you must have an active connection to play live casino, sports, or place bets. Your login and balance refresh every time you connect. Games with cached graphics (like Crash) may seem faster on repeat plays, but no real money transactions happen offline.
I lost my password. Can I recover it through the App?
Yes. In the ef99 App login screen, tap "Forgot Password?". Enter your registered email or phone number. You'll receive a recovery link (check spam folder). Click the link to reset your password. If you can't access your email, contact our 24/7 support at [email protected] with your account details, NID, and a photo of yourself holding your NID. We'll verify and reset your password in under 2 hours. For security, log in here to manage your account.
Will ef99 App drain my phone battery quickly?
ef99 App is optimized for mobile devices and uses less battery than the web browser. Slot games with low graphics (like Color Game) drain minimal battery—you can play for 3+ hours before needing a charge. Live casino with high-quality video streams uses more power (2–3 hours per charge). Tips to extend battery: lower screen brightness, close other apps, use WiFi instead of 4G (uses less battery), and play in airplane mode for offline-compatible games. Disable background location tracking in Settings if not needed.
Can I use ef99 App on a tablet or dual SIM phone?
ef99 App works on most Android tablets and dual SIM phones running Android 8.0+. Screen size adapts automatically—tablets show a wider layout for more games at once. Dual SIM phones can install and run the app without issues (both SIM slots work independently). Install steps are identical. If you use the app on multiple devices with the same account, make sure to log out on one before logging in on another to avoid session conflicts. All transactions and balance sync instantly across devices.
