Arcade machines, especially coin-operated ones, are designed with various anti-tamper mechanisms to prevent theft, cheating, and unauthorized modifications. Here are the most common types:

1. Physical Locks and Latches – Heavy-duty locks secure coin boxes, control panels, and backdoors to deter tampering.

2. Tamper-Evident Seals – Adhesive or mechanical seals show visible signs if someone tries to open the machine.

3. Electronic Protection Circuits – Sensors detect voltage fluctuations or unauthorized board swaps, triggering shutdowns.

4. Custom Fasteners – Proprietary screws and bolts prevent easy disassembly without specialized tools.

5. Software Locks – Encrypted firmware or password-protected settings prevent unauthorized changes to game software.

These mechanisms ensure arcade machines remain secure while maintaining fair play and profitability for operators.
