"One or two players control chickens who can be made to run across a ten lane highway filled with traffic in an effort to "get to the other side." Every time a chicken gets across a point is earned for that player. If hit by a car, a chicken is forced back either slightly, or in some modes, pushed back to the bottom of the screen. The winner of a two player game is the player who has scored the most points in the two minutes, sixteen seconds allotted.
The chickens are only allowed to move up or down. The chicken sprite has limited animation and a cluck sound is heard when a chicken is struck by a car.
Comparisons are often made to Frogger, which has different gameplay but also features crossing a street filled with moving vehicles. Both games were developed independently at the same time. Similarities did help sales when Frogger was popular in the arcades and a home version was not yet available."
