Installation paths for castle
We offer three ways to access castle on mobile devices. Android users can download our native APK file directly from our website and install it on their device. iOS users can access castle through Safari or Chrome by visiting our mobile site — no app store download required. Desktop and tablet users can also access castle through any modern web browser. Each path leads to the same account and balance, so you can switch between devices without losing progress.
Android APK installation steps
Installing the castle Android app requires four steps. First, download the APK file from our website to your device. Second, navigate to your device settings and enable installation from unknown sources (this allows you to install apps outside the Google Play Store). Third, open your file manager, locate the downloaded APK file, and tap it to begin installation. Fourth, follow the on-screen prompts to complete installation, then open the app and log in with your castle account credentials.
- Download the castle APK file from our website
- Enable "Unknown Sources" in your device settings under Security
- Open the APK file from your file manager and tap Install
- Launch the app and log in to your castle account
iOS browser access
iOS users do not need to download an app. Instead, open Safari (or Chrome) on your iPhone or iPad and navigate to castle's mobile site. Bookmark the page for quick access in future sessions. The mobile browser experience is optimized for touch navigation and smaller screens, so gameplay and account management work smoothly without installation. You can also add castle to your home screen as a web app shortcut, which creates an icon that launches the mobile site directly.
App versus browser experience
The native Android app and mobile browser both connect to the same castle account and balance. The app offers advantages such as offline access to game rules and tournament schedules, push notifications for upcoming events, and slightly faster load times due to local caching. The browser requires an internet connection for all features but avoids the installation step and works on any device with a modern browser. Both paths support deposits via DANA, e-wallet, mobile banking, local payment, online payment, and bank transfers (e-wallet, mobile banking, local payment, online payment, e-wallet). Choose based on your preference: if you value speed and offline features, use the Android app; if you prefer simplicity and cross-device flexibility, use the browser.
Same account across all devices
Your castle account balance and game history sync across Android, iOS, and web. Log in from any device and your account state updates immediately. You do not need separate accounts for different platforms.
Device compatibility
The castle Android app requires Android 7.0 or later. Most devices released in the past five years meet this requirement. iOS users need iOS 12 or later to access the mobile browser version. Tablets (both Android and iPad) are fully supported and display castle in a tablet-optimized layout. If your device is older than these specifications, you can still access castle through a desktop web browser on a computer.
Troubleshooting common installation issues
If you encounter problems installing the Android APK, first verify that you have enabled "Unknown Sources" in your device settings. Some devices hide this setting under Security or Apps. If the APK file fails to install, try clearing your browser cache and downloading the file again. If you see a certificate warning during installation, this is normal for APK files downloaded outside the Play Store — tap "Install anyway" to proceed. If the app crashes after installation, restart your device and try opening the app again. For persistent issues, contact our support team via the help portal or email — our team responds during business hours.
Data, permissions, and account security
The castle app requests permission to access your device's internet connection (required for all features) and, on Android, permission to send notifications (optional but recommended for tournament alerts). We do not request access to your contacts, photos, or other personal files. Your account credentials are encrypted in transit and stored securely on our servers. We do not store your password on your device — only a session token that expires when you log out. If you uninstall the app, your account remains active and you can log back in from any device. If you suspect unauthorized access to your account, change your password immediately through your Account settings or contact our support team.
