Arcade game machines are designed to withstand tampering and cheating, ensuring fair gameplay and revenue protection for operators. Here are the most common anti-tampering mechanisms used:

1. Physical Locks & Enclosures – Heavy-duty locks and reinforced cabinets prevent unauthorized access to internal components like circuit boards and coin mechanisms.

2. Tamper-Evident Seals – Adhesive seals or stickers break when removed, alerting operators to potential tampering attempts.

3. Encrypted Firmware – Modern arcade machines use encrypted software to prevent code manipulation or unauthorized modifications.

4. Motion & Tilt Sensors – These detect tilting or shaking, common tactics to exploit mechanical games, and trigger alarms or shut down the machine.

5. Secure Coin Mechanisms – Anti-jamming and counterfeit detection systems prevent coin fraud and ensure accurate payouts.

6. Monitoring Software – Some machines log unusual activity, such as repeated high scores, to flag potential cheating.

By integrating these mechanisms, arcade operators can maintain game integrity and profitability while deterring dishonest players.
