Arcade machines have long been a staple in competitive gaming, and ensuring fair play is crucial. To prevent cheating or tampering, manufacturers implement multiple security measures.

1. Hardware Locks and Seals: Many arcade cabinets use tamper-evident seals and locks to prevent unauthorized access to internal components. Any attempt to open the machine leaves visible marks, alerting operators.

2. Encrypted Software: Firmware and game software are often encrypted to prevent hacking or code manipulation. Regular updates patch vulnerabilities, keeping cheaters at bay.

3. Secure Input Devices: Buttons, joysticks, and other controls are hardwired or use proprietary connectors to deter tampering. Some machines also employ anti-jamming mechanisms to block cheat devices.

4. Surveillance and Monitoring: High-stakes arcades use cameras and sensors to detect suspicious behavior, while networked machines log gameplay data for review.

5. Anti-Tilt Mechanisms: Tilting or shaking the machine to influence gameplay triggers tilt sensors, penalizing or disqualifying players.

By combining these methods, arcade machines maintain integrity in competitive environments, ensuring a fair experience for all players.
