Play 3 games simultaneously on one computer with one Joystick. 3 games (Pacman, Pong, and Space-Invaders) are played at the same time. The games each take up a full screen, and are in either red, green, or blue. When two colours (games) overlap, the colours are mixed to generate the resulting colour, so it looks like all 3 games are transparent. It is possible to play all 3 games at once with one joystick, but you can also disable the graphics of the games, as well as adjust their brightness.
