The 7h777 app is ready for both Android and iOS
Only download from this page — avoid third-party sites.
Choose the right method for your device
Tap the "Download Android APK" button above. The file will be saved to your phone's "Downloads" folder. On mobile data, the download typically takes 1–2 minutes.
Go to Phone Settings → Apps (or Security) → enable "Install unknown apps" or "Install from unknown sources." On Samsung phones, this is usually found under Settings → Biometrics and Security.
Open your File Manager app → go to the Downloads folder → tap the 7h777.apk file. Tap "Install" and the installation will be done within 20–30 seconds.
The 7h777 icon will appear on your home screen. Tap it and the login screen will open. If you already have an account, log in — otherwise, you can register a new one.
When the app asks for notification permission on first launch, tap "Allow." This lets you receive live odds updates, bonus offers, and match results in real time.
To install 7h777 on iOS, you must use the Safari browser. This method does not work in Chrome or Firefox. Open Safari and go to 7h777.world.
Tap the button in the middle of the bottom of the Safari screen — the one with an upward arrow inside a square box.
Scroll through the menu that slides up from the bottom, find "Add to Home Screen," and tap it.
The next screen will show the name "7h777" — keep it as is and tap the "Add" button in the top-right corner. That's all there is to it.
The 7h777 icon will now appear on your home screen. Tap it for a full-screen experience without any browser bar — just like a native app.

Latest changes in the 7h777 app
Your safety is our top priority when downloading and using the 7h777 app
Mobile apps have transformed online betting in Bangladesh. What once required sitting at a computer can now be done on the go — on the bus, in the street, or over a cup of tea. The 7h777 app makes that shift even easier and more enjoyable.
Before downloading the app, many people have questions — Is it really safe? Is it okay to install an APK file? Will it work on my phone? These are completely valid concerns. This page answers all of them, so take a moment to read through and download with confidence.
Many users hesitate when asked to allow "Unknown sources" or "Install unknown apps." In practice, this permission simply allows APK files from outside the Play Store to be installed — it is required for 7h777 and many other legitimate apps. Once installation is complete, you can turn this permission back off at any time without affecting how the 7h777 app works.
One important warning — only download the APK from 7h777's official website or this download page. APK files from other sites or WhatsApp groups can be dangerous, as they're more likely to be fake or infected with malware.
Many people in Bangladesh use budget phones — Symphony, Walton, or older Xiaomi models. 7h777 was built with this reality in mind. The app runs smoothly on any phone with Android 6.0 or above, as long as it has at least 1 GB of RAM.
If your device has less than 1 GB of RAM, the app will still run but live casino video streaming may feel a bit sluggish. In that case, stick to the Sports Betting section — it runs excellently on much fewer resources.
The PWA method for 7h777 on iPhone may sound a little complicated, but it's actually very straightforward. Once added to your home screen, you won't need to open Safari every time — just launch it directly from the icon, and the browser address bar won't be visible. The experience feels exactly like a native app.
Another major advantage of the iOS PWA is that updates are completely hands-free. Whenever a new version of 7h777 goes live, it loads automatically the next time you open the app — no action needed on your end.
Once the app is installed, the first thing to do is enable notifications — otherwise you'll miss live odds changes and flash bonus offers. Then save your payment method. If you use bKash or Nagad, saving your number once means you only need to enter the amount next time.
Enabling biometric login means you never have to type your password again. It is especially useful for placing quick in-play bets during a match — particularly when a wicket falls and the odds shift in seconds.
Older versions will not have access to new payment methods or features. In some cases, an outdated APK may fail to connect to the latest servers, causing the app not to open or data not to load. 7h777 usually sends a notification when an update is available — install it as soon as you see it.
Updating works just like the initial installation — simply download the new APK and install it the same way, and it will update automatically. Your account, balance, and bet history will not be affected.
Downloading a 24 MB file over a 3G network takes around 2–3 minutes on mobile data. If you'd like to save data, download over your home Wi-Fi or office network. That said, downloading on mobile data is perfectly fine — 24 MB fits easily within the average data package in Bangladesh.
If you run into any issues during download or installation, our Bengali support team is available 24/7 to help.
