Video game is an electronic game that interacts with a user interface to generate visual feedback on a video device. The electronic system in which the video game is played is called as platforms; personal computers and video game consoles are some of the examples. These range from large computers to small handheld devices. Arcade games which were once specialized video game, have gradually declined in use.



The game controller is the input device used to play or operate the Video games, which varies across platforms.
