Up 'n Down is a Racing video game developed and published by Sega. It was first released in 1983 as an arcade game, later ported to the Atari 2600 and game consoles and the Atari Xe and Commodore 64 home computer.
Up 'n Down is a vertically scrolling game that uses a pseudo-3D perspective. In the game, the player controls a purple buggy that resembles a Volkswagen Beetle. The buggy moves forward along a single lane track; Pressing up or down on the joystick causes the buggy to speed up or slow down, pressing the right or left causes the buggy to change lanes at an intersection, and pressing the "jump" button causes the buggy to jump in the air. Jumping is necessary to avoid other cars on the road; the player can either jump all the way over them, or land on them for points.
To finish the round, the player must collect 10 colored flags by running through them with the buggy. If the player passes the flag without raising it, she will reappear later in the round. Roads feature ups and downs that affect the speed of the buggy, and bridges that must be crossed. The player misses a turn when the buggy either collides with another vehicle without jumping on it, or jumps off the road into grass or water.
