Mobile app features for slots, live games, and payments
21 Casino Mobile App Overview
21 Casino offers a mobile app for iOS and Android that covers the full casino lobby: slots, live casino tables, and a small set of instant-win games. The app supports real-money deposits and withdrawals, balance and bonus tracking, game search, and session history, with login via email or phone number. Payments inside the app include bank cards and e-wallets, while some regions also get local bank transfer options; availability depends on the player’s country and the selected currency.
The app fits players who want one-handed navigation and fast access to the last played games, with a layout optimized for small screens and portrait mode. It works well for live casino users because it keeps table limits visible before joining a table and allows quick switching between tables without returning to the main lobby. It is less convenient for players who rely on advanced filtering or multi-window play, since the app focuses on a simplified lobby and single-game sessions.
21 Casino App Security
- Encryption: The app encrypts data in transit with TLS 1.2+ and stores sensitive tokens using OS-level secure storage (iOS Keychain / Android Keystore).
- Payment Protection: Card payments run through PCI DSS–compliant payment processors, and the app does not store full card numbers or CVV after authorization.
- Biometrics: 21 Casino supports Face ID / Touch ID on iOS and fingerprint authentication on Android to unlock the app and approve logins on supported devices.
- Account Controls: Users can enable two-factor authentication (OTP) and receive login notifications to flag new-device access.
- Session Security: The app uses short-lived sessions with automatic timeout after inactivity and requires re-authentication for withdrawals or profile changes.
