Game access, wallet tools and live notifications

The cv4 app opens Aviator, Gates of Olympus and our Evolution live tables directly from your home screen. Tap a push notification when a deposit clears, unlock the lobby with fingerprint or face ID, and switch between cricket markets and slot rooms without closing the window. We keep your betslip, wallet balance and session state live across tabs so you can move

between BPL odds and Dragon Tiger rounds in real time. Dark mode adapts to your device settings, and the quick-deposit widget lets you top up from bKash, Nagad or Rocket mid-session without leaving the game grid.

Browser requirements and screen support

Our mobile layout works on any device that runs a modern browser — iOS Safari from version 12, Chrome and Firefox from the past two years, and Edge on Windows tablets. The lobby adapts to screens from 320 pixels wide upward, so older budget phones and current flagships both render the grid correctly. Portrait and landscape orientations are supported; live-table streams switch to widescreen framing when you rotate your device. We recommend keeping your operating system and browser updated for the smoothest performance and the latest security patches, though we do not enforce a strict OS floor.

Browser compatibilityChrome, Safari, Firefox and Edge from the past two years; older versions may load the lobby but might not support fingerprint login or push notifications.
Screen size supportThe layout scales from 320-pixel-wide budget phones to 12-inch tablets, adjusting touch zones, game-tile size and the deposit bar so everything stays reachable on any screen.
Orientation handlingPortrait mode stacks the game grid vertically for scrolling; landscape switches live tables and slots to widescreen framing so you see more of the table felt or reel window.
Account requirementsYou need a verified cv4 account with a linked mobile number; biometric login and push notifications require you to grant permissions during your first session on the device.
Checking app availabilityVisit our support page or contact the live-chat team to confirm whether a native Android or iOS build is currently offered in your region; browser access remains available across all eligible areas.

Features that speed up every session

We added the tools Bangladesh players asked for: biometric login that skips the password screen, push alerts when your withdrawal is verified, and an offline lobby preview so you can browse game tiles before your connection stabilizes. The quick-deposit bar sits above the game grid — one tap opens your wallet choice and pre-fills the account number.

Biometric unlock

Sign in with your fingerprint or face ID so you skip the OTP step when you return to the lobby, keeping your session secure and your login instant on supported Android and iOS devices.

Push notifications

We send a notification when your bKash, Nagad or Rocket deposit reaches your wallet, when a withdrawal is verified, and when new promotions go live, so you stay in sync without refreshing the page.

Dark mode

The app follows your device theme and switches to dark mode automatically, reducing screen glare during late-night slots or early-morning cricket markets so your eyes stay comfortable across long sessions.

Offline lobby preview

Browse cached game tiles and provider categories when your connection drops, then reload the live lobby once you reconnect — no blank screen, no lost place in the catalogue as you scroll through slots.

cv4 Three steps to mobile lobby access

Three steps to mobile lobby access

We designed mobile access around the browser you already have, so there's no app-store approval wait or APK sideload to manage. Open cv4 on any device running a current browser — Chrome, Safari, Firefox or Edge all work. The site detects your screen size and serves the mobile layout automatically, with larger touch zones for deposit buttons and game tiles. Sign in

with your account credentials or register a new wallet if you're visiting for the first time; we'll send an OTP to confirm your mobile number. Once you're in, the lobby loads your last game category and your session persists across tabs, meaning you can check cricket odds in one window and spin Mahjong Ways in another without signing in twice. Add the

page to your home screen from your browser menu if you want a one-tap shortcut.

  • Open the site in your browser — Visit cv4 from Chrome, Safari, Firefox or Edge on your phone or tablet; the mobile layout appears automatically with no install step required.
  • Sign in or register your account — Enter your mobile number and OTP code, or create a new wallet by linking your bKash, Nagad or Rocket number during the registration flow.
  • Add to home screen (optional) — Tap your browser's menu and choose 'Add to Home Screen' for a shortcut icon that opens the lobby in one tap, launching in full-screen mode without the address bar.

You will if you grant notification permissions during your first visit. We send alerts when your bKash, Nagad or Rocket deposit reaches your wallet, when a withdrawal is verified, and when new promotions go live.

Yes, on devices that support biometric authentication. Enable it in your account security settings, and the next time you open the site your phone's fingerprint or face scanner will unlock the lobby without entering your password.
