The game is designed for 4 people. Each person holds a controller with 1 person as the quiz master (the blue controller). The quiz master asks a multiple choice question and each contestant is given 7 seconds to answer A, B, C or D. You have to lock your question in with the controller so there's no going back on your decision. After 7 seconds are up, if you got the question wrong, you'll definitely know it. Your controller sends some 'pleasant' electric shocks up your arm, making sure you know just how wrong you are. Comes with 600 questions, dice, scoreboard and pen. NOT for people under 14.
