Maneuver a "worm" around the screen and eat "tokens" ... after nine tokens are eaten move to the next level. Increasingly difficult obstacles appear as new levels are reached. Hit an obstacle [or the worm itself] and you lose a life ... lose three lives and the game is over. Get through all ten levels to complete the game. Options are available for setting colors (playing field border, worm head, worm body, obstacles, etc.) ... sounds played when certain events happen (eat token, hit an obstacle, move to next level, etc.) ... speed of the worm (from very slow to very fast) ... starting level.
