The h31 app brings the full casino experience to your Android or iOS device. Play Ocean Phoenix, Fishing Disco, Dinosaur Tycoon, and every other h31 game from anywhere in Bangladesh. Deposit via bKash or Nagad, claim bonuses, and withdraw your winnings — all from one lightweight app that runs smoothly even on budget phones.
Why Use the App
The h31 app is built for real players — fast, lightweight, and packed with everything you need to play, deposit, and cash out on the go.
The h31 app is optimised for mobile networks in Bangladesh. Games like Ocean Phoenix and Fishing Disco load in under two seconds even on a 4G connection. No buffering, no lag — just smooth gameplay from the moment you tap. The app caches game assets locally so repeat sessions load even faster.
Deposit and withdraw in Bangladeshi Taka without leaving the h31 app. bKash, Nagad, and Rocket are all integrated directly into the cashier section. Deposits are credited instantly and withdrawals are processed the same day. The minimum deposit is ৳200 and there are zero fees on any transaction.
Never miss a promotion again. The h31 app sends push notifications when a new bonus is available, when your withdrawal is processed, or when a limited-time offer goes live. You can customise which notifications you receive from the app settings — turn off what you don't need and keep what matters.
Log in to your h31 account with your fingerprint or face ID — no need to type your password every time. Biometric login is available on all supported Android and iOS devices. Your credentials are stored securely in your device's hardware security module and are never transmitted to h31 servers.
The h31 app uses a dark interface by default — easier on your eyes during late-night sessions and kinder to your phone battery. The app is also optimised to use minimal CPU and RAM, so it runs well on older or budget Android devices without draining your battery or slowing down other apps.
The h31 app updates automatically in the background. New games, bonus features, and security patches are delivered without you having to manually download anything. You always have the latest version of the h31 app without any effort — just open it and play.
Android Installation
Visit the h31 website or open the download link. If you don't have an account yet, register free — it takes under three minutes. Existing players can log in directly.
Since the h31 APK is downloaded directly (not from the Play Store), go to your Android Settings → Security → enable "Install from Unknown Sources" or "Install Unknown Apps" for your browser. This is a one-time step.
Tap the Android download button on this page. The h31 APK file (around 18MB) will download to your phone in seconds on any mobile data connection.
Open the downloaded APK from your notifications or file manager. Tap Install, wait a few seconds, then tap Open. Log in with your h31 credentials and you're ready to play.
Tip: After installing, you can turn "Unknown Sources" back off in your settings for extra security.
iOS Installation
The h31 iOS app installs as a Progressive Web App (PWA) through Safari. Open Safari and navigate to h31.one. Chrome and Firefox on iOS do not support PWA installation — use Safari for the best experience.
In Safari, tap the Share icon at the bottom of the screen (the square with an arrow pointing up). This opens the iOS share sheet with a list of actions.
Scroll down in the share sheet and tap "Add to Home Screen". Give it a name (h31 works fine) and tap Add. The h31 icon will appear on your iPhone home screen just like a native app.
Tap the h31 icon on your home screen. It opens in full-screen mode without the Safari browser bar — a clean, app-like experience. Log in and start playing immediately.
iOS 13+ is required. The PWA works on iPhone 6s and newer running iOS 13 or above.

The Full Picture
The h31 app was built with Bangladeshi players in mind from day one. Most online casino apps are designed for high-end phones and fast Wi-Fi connections — the h31 app is different. It runs smoothly on the kind of Android phones that most people in Bangladesh actually use, and it works well on mobile data, not just Wi-Fi. Whether you're on Grameenphone, Robi, Banglalink, or Teletalk, the h31 app adapts to your connection speed and keeps the experience smooth.
One of the biggest advantages of the h31 app over playing in a browser is the integrated payment experience. When you deposit via bKash inside the h31 app, the app hands off directly to the bKash interface and returns you to your game the moment the transaction is confirmed. There's no copying and pasting account numbers, no switching between apps, and no waiting for a page to reload. The same applies to Nagad and Rocket — the whole deposit flow takes under 60 seconds.
The h31 app also gives you access to the full game library — not a cut-down mobile version. Ocean Phoenix, Leprechaun Riches, Fruit Shop, Ice Hockey, Fishing Disco, and Dinosaur Tycoon all run natively in the app with the same graphics and features as the desktop version. The touch controls are optimised for mobile so spinning reels, placing bets, and navigating menus all feel natural on a touchscreen.
Security in the h31 app is the same standard as the website — 256-bit SSL encryption on all data, biometric login support, and automatic session timeouts after inactivity. If you lose your phone or it gets stolen, you can log out of all active sessions remotely from any browser by visiting your h31 account settings. Your balance and account data are stored on h31 servers, not on your device, so there's nothing to lose if your phone is replaced.
For players who are new to h31, downloading the app is a great way to start. Register directly inside the app, verify your mobile number with an OTP, make your first deposit via bKash or Nagad, and your 100% welcome bonus is credited automatically. The whole onboarding process — from download to first game — takes under five minutes. If you run into any issues, the live chat support is accessible directly from the app's help section.
The h31 app is updated regularly. New games are added to the library, bonus features are improved, and any reported bugs are fixed quickly. Updates happen automatically in the background on Android — you don't need to manually download a new APK every time there's an update. On iOS, the PWA refreshes automatically when you open it, so you're always on the latest version without any effort.
Play Responsibly: The h31 app includes built-in responsible gaming tools. Set deposit limits, session time reminders, or request a cooling-off period directly from the app settings. h31 is an 18+ platform. Visit our Responsible Gaming page for more information.
