A LCD game is a very small, handy and portable electronic device for playing interactive video games. It often concerns a miniaturized version of a well-known computer game. The control buttons, the screen and the speakers are all part of one and the same housing.

A handheld TV game or plug and play game is an integrated home video game console and game controller, usually battery powered, which connects directly to a television. It's typically designed to look like a toy or classic game console controller with the addition of a composite video cable to connect the unit. Because the game software is integrated into the game unit and almost never designed to be changed by the user, these game systems are typically marketed as electronic toys or collectibles rather than game consoles.
