Arcade game manufacturers employ multiple strategies to prevent cheating and tampering, ensuring fair play and longevity of their machines.

1. Tamper-Proof Hardware: Many arcade cabinets are built with reinforced casings, security screws, and sealed components to deter physical tampering. Some even use sensors to detect unauthorized openings.

2. Encrypted Software: Firmware and game software are often encrypted to prevent hacking or code manipulation. Regular updates patch vulnerabilities and enhance security.

3. Anti-Cheat Mechanisms: Built-in algorithms detect abnormal gameplay patterns, such as impossible high scores or rapid button inputs, flagging potential cheaters.

4. Surveillance and Monitoring: Some machines connect to central servers, allowing operators to monitor gameplay data in real-time and identify suspicious activity.

5. Secure Payment Systems: Coin mechanisms and digital payment interfaces are designed to resist manipulation, ensuring revenue integrity.

By combining these measures, manufacturers protect arcade games from fraud while maintaining player trust and operational reliability.
