Snoopy is a simple platform game taking place over 20 single-screen levels. In each level, Snoopy's job is to travel from the left edge of the screen to the right edge. Various dangers, both stationary and mobile, hinder his progress. After 20 levels have been completed, the sequence starts again from the beginning, but this time at a faster pace.
The game's only relation to the Peanuts comic strip is the main sprite looking like Snoopy. No other Peanuts characters appear or are mentioned, and the game does not involve Snoopy's famous strange behaviour from the comic strip.
On the computer the controls are arrow keys to move and control to jump.
