Arcade game manufacturers employ multiple physical security layers to prevent tampering with internal components. Custom-designed cabinets feature robust locking mechanisms on doors and access panels, requiring specialized keys unavailable to the public. Internal printed circuit boards (PCBs) are often coated with black epoxy resin, obscuring critical chips and preventing circuit modification. Security screws with unique drive patterns—such as Torx, spanner, or custom heads—deter unauthorized access to sensitive areas. Manufacturers implement tamper switches that trigger security modes when cabinets are opened improperly, potentially logging events or disabling gameplay. Many arcade PCBs incorporate custom chips with proprietary code that's difficult to reverse-engineer. Coin boxes utilize sophisticated locking systems and are physically anchored to prevent theft. Some manufacturers even install security cameras within cabinets to monitor for interference. These comprehensive measures protect against cheating, unauthorized repairs, and component theft, ensuring arcade operators maintain revenue streams and game integrity in public environments where machines face constant security challenges.
