Arcade machines are designed with various tamper-evident features to prevent unauthorized access, theft, or cheating. Here are the most common types:

1. Tamper-Evident Seals: These adhesive labels or stickers break or leave a mark when removed, indicating tampering. They are often placed on coin doors or access panels.

2. Security Locks: High-quality locks with unique keys or combinations secure critical compartments, deterring unauthorized entry.

3. Anti-Tampering Sensors: Electronic sensors trigger alarms or disable the machine if tampering is detected, such as when the cabinet is opened.

4. Reinforced Panels: Heavy-duty materials and hidden fasteners make it difficult to dismantle the machine without leaving visible damage.

5. Serialized Components: Unique serial numbers on parts help track replacements or theft, discouraging component swapping.

These features ensure arcade machines remain secure, fair, and operational for players and operators alike.
