Take the 21cuci experience wherever you go. The 21cuci mobile app gives you full access to Live Casino, Slots, Fish Shooting Games, exclusive promotions, and account management — all in one fast, lightweight platform.
The days of playing at a desktop are long gone. Most Malaysian players today prefer gaming directly from their smartphones — anywhere, anytime. 21cuci understands this need and has invested in developing a mobile app that is truly optimised for the best experience for Malaysian users.
The 21cuci app is not just a scaled-down web version. It is rebuilt from the ground up for mobile — with an intuitive interface, touch-friendly buttons, fast navigation, and Live Casino video streams optimised for Malaysia's 4G/5G connections. The result is a smoother gaming experience compared to browsing the site on a mobile browser.
One thing 21cuci users frequently praise is how lightweight the app is. At only around 35MB for Android and requiring no significant storage space on iOS, the 21cuci app will not burden your phone or quickly drain your data quota. The streaming optimisation technology used ensures live casino video runs smoothly even on standard 4G data.
Optimised for the latest ARM chips — Slot Games, Fish Shooting Games, and Live Casino run without any lag or stuttering.
Receive instant notifications for new promotions, deposit and withdrawal status directly to your phone without needing to open the app.
Supports login using fingerprint or facial recognition — secure and faster than typing your password every time.
The app updates automatically in the background — you are always on the latest version with the newest features and security improvements.
The 21cuci app installation process is designed to be as simple as possible — even for users who are not very familiar with mobile technology.
Go to Settings → Security → enable "Unknown Sources" or "Install Unknown Apps" to allow APK installation from outside the Google Play Store.
Click the "Download Android APK" button on this page. The 21cuci APK file will download directly to your phone's Downloads folder within seconds.
Open File Manager, locate the downloaded APK file, tap on it, and follow the installation instructions. The process takes less than one minute.
Open the 21cuci app, log in with an existing account or register a new one, make a deposit, and start enjoying all the games directly from your phone.
Make sure you are using the Safari browser — this is essential for the 21cuci PWA (Progressive Web App) installation process to run smoothly on your iOS device.
Access the 21cuci site via Safari. You will see a prompt to install the 21cuci web app directly to your iPhone home screen — free and secure.
Tap the "Share" icon at the bottom of Safari, scroll down, and select "Add to Home Screen". The 21cuci app icon will appear directly on your iPhone home screen.
Tap the 21cuci icon from your home screen to launch the app in full-screen mode. The experience is almost identical to a native app without taking up significant storage space.
Many players who initially played through a regular web browser eventually switched fully to the 21cuci app after trying it — and there are solid reasons for that. The in-app experience feels smoother, more responsive and more enjoyable compared to the web version.
One of the biggest advantages of the 21cuci app is the ability to play without interruption from incoming calls or other notifications. When you are in full game mode inside the app, the interface is clean with no distracting elements. You can focus entirely on the game and make wagering decisions with greater calm and precision.
Enjoy live casino, slots and fish shooting games in full screen mode without distracting browser bars — a more immersive experience that feels like playing on a real gaming device.
Save your preferred payment methods in the app and make deposits with a single tap. FPX, e-wallet and local bank methods are all available directly within the app.
View a full record of all your bets, deposits and withdrawals directly from the app. Data is stored securely and can be filtered by date, game type or amount.
Track your VIP points progress, check claimable rewards and receive alerts when you are promoted to a new VIP level — all displayed in real time within the app.
The dark interface of the 21cuci app is designed for comfortable night-time gaming — reducing eye strain while saving your phone's battery at the same time.
Never miss a great deal — the 21cuci app sends instant notifications when new promotions launch, including exclusive offers available only to app users.

Player trust is 21cuci's number one priority. That is why every aspect of the app's security is carefully designed. Your personal data — including phone number, bank account details, and transaction history — is all encrypted using industry-standard 256-bit SSL protocol.
The 21cuci app never stores your sensitive information locally on your device without protection. Every login session is secured with a periodically regenerated authentication token, and biometric login ensures only you can access your account even if your phone falls into someone else's hands.
The KYC (Know Your Customer) verification required for withdrawals only needs to be completed once — directly through the app using your phone camera. Upload your ID card photo and selfie in under 5 minutes, and verification is typically approved within 1 working hour.
21cuci also provides personal game limit controls within the app — you can set daily deposit limits, session wagering limits, and loss limits according to your own budget. This is part of 21cuci's commitment to responsible and sustainable gaming for all players.
The 21cuci app has undergone independent third-party security testing. No adware, spyware, or malicious code — guaranteed safe to install on your smartphone. For more information on how your data is protected, please read Privacy Policy us.
The 21cuci app has been tested and confirmed to work well across a wide range of phone brands and models popular among Malaysian users.
Minimum requirements: Android 5.0 or above with at least 2GB RAM, or iOS 13 or above for Apple devices. A 4G or WiFi connection is recommended for the best Live Casino experience. The 21cuci app also works on 3G connections, though Live Casino video quality may be reduced.
