Twelve chairs, numbered 1 to 12, each have an electric shock device. Players are Attackers and Defenders. Attackers leave while Defenders secretly activate one chair’s shock. Attackers return and sit on a chair. Defenders activate the device to check if the chair is electrified. No shock: The Attacker earns points equal to the chair’s number. Shocked: The Attacker’s score is zero, and they gain one Shock Point. Used chairs are removed.
