Bop It is a series of battery-powered games made by Hasbro. The aim of the game is to respond quickly to the directions that come out of the game's speakers. These directions are given in a way that requires the player do use different devices on the machine, such as pull handles, twist cranks, spin wheels, or toggle switches. A beat is played during the game and the beat will get faster as the player scores more points, making it harder for the player to respond.
