Chase the Chuck Wagon is a 1983 promotional video game written by Mike Schwartz for the Atari 2600 and distributed by Purina.
It was available only via mail order by sending in proofs of purchase to Purina. In the 1970s and 1980s, popular television commercials for Purina dog food included a dog chasing a tiny chuckwagon. The gameplay is loosely based on this premise.
Chase the Chuck Wagon is a maze game. The object of each maze screen is to move Chuckie, the dog, through mazes of four different designs and escape through the opening directly below the chuckwagon. The player has limited time (60 or 30 seconds depending on the difficulty setting) per maze to accomplish this.
There are two obstacles in each maze: the dog catcher moves through the maze, and if he touches Chuckie, the player loses one life; the bouncing object (bone, etc.) travels back and forth across the maze unhindered by the maze walls, and if it touches Chuckie, he will be frozen momentarily (signified by the maze changing color), making it more difficult to reach the end of maze within the time limit or avoid the dog catcher.
