Bop It
Groove It is an audio game made by Hasbro whose instructions have been copyrighted in 2003. It was voiced by Adam Rossi. With similar game play to the Bop It games, Groove It employs photodetection technology to determine the player's hand position. As with Bop It games, Groove It issues voice commands, however in this case the commands are: "the scratch", "the slide", and "the zoom". The game is more tolerant of errors than the Bop It games, allowing as many as three missed commands in some modes. The game requires a score of 250 to win, has a maximum score of 300, and uses a ranking system.
