Arcade game manufacturers employ multiple strategies to prevent tampering and cheating in public settings, ensuring fair gameplay and revenue protection.

1. Secure Hardware Design: Arcade cabinets are built with tamper-proof locks and reinforced casings to prevent physical access to internal components. Critical circuit boards are often encased in epoxy or shielded to deter modification.

2. Encrypted Software: Modern arcade games use encrypted firmware and secure boot processes to prevent unauthorized code injection or ROM swapping. Checksum verification detects altered software.

3. Coin Mechanism Protection: Coin slots and payment systems are equipped with sensors and anti-jamming technology to prevent coin fraud, such as slug use or forced entry.

4. Real-Time Monitoring: Many arcades connect machines to centralized systems that track gameplay anomalies, sudden score spikes, or repeated resets—common cheating indicators.

5. Anti-Tilt Mechanisms: To discourage physical manipulation, games include tilt sensors that freeze gameplay or trigger alarms if the cabinet is shaken or tilted excessively.

6. Operator Settings Lock: Critical settings (difficulty, pricing) are password-protected, allowing only authorized personnel to adjust parameters.

By combining these physical and digital safeguards, manufacturers maintain arcade integrity while providing a cheat-free experience for players.
